1. ELMA Control Program Characteristics
ELMA is a control program for Electricity Meter Test equipment. Basic program characteristics: • user-accessible control; the program is designed for MS Windows 7 and newer • possibility to communicate with the program in any chosen language, to switch between languages without necessity of quitting the program, and user definition or modification of language-specific texts • automatic generation and printout of user-defined protocols using Microsoft Word program or Fast Report system • user-defined electricity meter types, tests, measurements and tolerances. All of those are stored in the database of the program • simple control of the measuring part of the program (warming up, adjustment, verification, protocol creation and printout) • full user control of the program configuration part (program configuration, database system, system of language localization and protocol templates creation) • built-in possibility of keeping the records of measured results (processing of the archive database by means of an external program) The program can be split into two basic parts: • measurement - involves measuring processes - the basic program activities aimed at tasks related to error evaluation of tested meters (setup and calibration of evaluation (OPS) units, warming up, tests, protocol generation and printout • configuration - comprises program activities associated with configuration and proper setup activities performed in the measuring part (program configuration, database system, language localization system and protocol templates generation) Control of the measuring part is simple and intuitive. The configuration part, however, requires deeper knowledge of the program, of the operating system (MS Windows) and of the utilized external programs (MS Word, Firebird database (older versions with Interbase support)). After system installation, default configuration is loaded and intervention is necessary only in special cases (for example introduction of new type of electricity meter, modification of output protocol, norm change, etc.). That’s why two possible approaches on how to work with program are possible: • measuring and configuration part are controlled by the same properly qualified personnel • the configuration part is accessed by an acknowledged properly qualified person and the measuring part i.e. the measurement itself is executed by skilled laborers having no access to the configuration
2. Program Installation and Backup
The program is installed from a CD (or USB flash drive) by running installation file (install.exe). Installer creates and installs all necessary files (program files, support communication libraries, initialization files, language files, databases, MS Word templates, Fast Report templates, …) into directory C:\ELMA. It is recommended (usually after a month or so) to backup periodically all files by copying the program's directory structure into a safe location, so that after an eventual operating system or disk drive breakdown it will be possible to complement the current versions of all the files within the new installation.

ELMA - Control System User‘s Guide 2.1 Configuration of databases Newest ELMA Control Software uses databases defined in configuration file database.ini located in same directory in which program exe file resides (typically c:\ELMA). Typically only one database pair is configured in this file and it contains only one block similar to this: [Local] ARCHIVE=c:\ELMA\DATABASE\archive.gdb ELMA=c:\ELMA\DATABASE\elmadb.gdb AliasNumber=0
Description of the content of database.ini file block: First line … name of the DB connection (showed in status bar of Control Software) defined by user Second line … definition (path and name) of archiving database file Third line … definition (path and name) of technology database file Fourth line … alias (block) number (0-99)* * Remark: Alias number can be specified as command line parameter when ELMA Control Software should be used with some database pairs directly. Syntax of program calling is: elma.exe -aX where X is alias number present and defined in database.ini file. In case when command line parameter -aX is not defined then default alias number 0 is used. In case when more separate databases should be prepared for usage (via command line parameters) then more blocks have to be present in database.ini file. Example of database.ini file with more blocks (more database definitions): [Local] ARCHIVE=c:\ELMA\DATABASE\archive.gdb ELMA=c:\ELMA\DATABASE\elmadb.gdb AliasNumber=0
[Old] ARCHIVE=c:\ELMA\DATABASE\archiveOLD.gdb ELMA=c:\ELMA\DATABASE\elmadbOLD.gdb AliasNumber=9
[ELMA02] ARCHIVE=10.114.35.51:c:\ELMA\DATABASE\archive.gdb ELMA=10.114.35.51:c:\ELMA\DATABASE\elmadb.gdb AliasNumber=22

3. Program Measurement Processes
Measuring process is essential action of the program towards performing necessary tasks of meter testing. The program involves following measuring processes: • setup and calibration of the (OPS) evaluation units • meters warming-up • tests in adjustment or verification mode • protocol creation and printout
Running of ELMA Control Software is hardware dependent. It is necessary to be connected to ELMA system (which consists of Signal Generator, Reference Standard, OPS units and optionally CMR-I units) or to Portable Test Equipment - PTE. However, if neither of such devices is available or demonstration purposes are required, ELMA SW will also run in DEMO mode, when no HW (except a PC) is required. If HW units are expected but not connected (intentionally or not) this window appears at ELMA SW start up (if enabled in Service tab of Configuration):
User can enter DEMO mode, check possible HW units’ communication issues by rechecking it again or close the program.
3.1 Setup and Calibration of Local Evaluation Units (OPS) The evaluation unit (OPS) is a computer operated system device which, in cooperation with the reference meter, scans and evaluates the electricity meter error. Each measurement position has its own evaluation unit. Correct functionality of the OPS requires its correct setup and calibration. It is necessary to perform the setup and calibration process each time the measuring system is switched on (OPS loses its previous calibration data each time it is switched off), after replacement or position change of the electricity meter or after change of the optical sensor head position. It is possible to perform the OPS setup and calibration in two ways: • individually (one specified OPS) • simultaneously (all OPSs on all activated measuring positions)
www.appliedp.com ELMASW-UG160-EN 7
ELMA - Control System User‘s Guide
Setup and calibration of a single OPS evaluation unit does not require a computer; it can be performed anytime, on condition that the electricity meter is supplied with sufficient energy (the induction electricity meter disk must move; the output LED of static electricity meter has to emit impulses). This setup and calibration type is usually used during the test performance in order to fine- tune the optical sensor setup. This process is started manually - first, user must set the proper position of the sensor and then initiate the auto calibration mode by pressing the SET button of OPS evaluation unit in MEAS mode. Auto calibration mode is terminated after approximately 15 seconds or the user can terminate it manually by MODE button of the OPS. Manual termination shouldn’t occur sooner as the meter’s disk makes whole disk rotation (two mark passages) or the LED of static meter once flashes. Simultaneous setup and calibration of the OPS is a process which can be run from the main program window by pressing the respective start button or from the program menu. After activation of this process, the computer initializes generation of respective load point and prompts the user to set all scanning heads. Control software adjusts OPTS units according to mounted meters on the bench (static or dynamic). It is necessary to adjust the position of the optical sensor head on the supporting arm with respect to the type of meter. With induction meter OPTS shines on a disk and captures the reflection of light. The quality of the captured reflection is shown by analogue way of LED INFO. This LED lights with maximum intensity in the transition mark. With static electricity meter OPTS is set to capture the flashing meter’s LED. Here the LED MARK flashes with the same intensity as the meter’s LED and LED INFO flashes with half-frequency. Then the computer upon user’s confirmation starts the auto calibration of OPS evaluation units. If the result of auto calibration does not reach the sufficient level, which is indicated by LED ERR, the setup process of the OPS evaluation units is necessary to repeat. The user’s most important task in the process of setting and calibration of OPS evaluation unit is the accurate setting of its optical sensor.
3.2 Warming-up of Meters The warm-up process is used to provide sufficient warming-up of all mechanisms of the meters being verified. It is possible to run the process and to quit it after a required time from the main program window by pressing the respective button or from the program menu. After activation of this process, computer generates the output signals of the respective load point and switches the OPS into the measuring mode.

ELMA - Control System User‘s Guide
3.3 Tests in Adjustment and Verification Mode A test is a basic measuring process of the program. In the verification mode the test result is directly sent to the output protocol. The program comprises two modes of tests: • adjustment mode • verification mode The main differences between the two modes are the following: • in the adjustment mode the automatic test is finished upon operator’s intervention while in the verification mode the test is completed automatically after measurement of specified number of samples, • manual test performed in the adjustment mode is always finished upon operator’s intervention, while in the verification mode it can be set also to automatic termination after a specified time, • in the adjustment mode, the OPS error tolerance window is set up wider than in the verification mode, so it is possible to evaluate meters with error many times exceeding the specified accuracy class. It is possible to run test from the main program window, by a mouse double-click on the respective line in the test window, or by selection in test window and pressing the respective start button, or running it from the program menu. The program distinguishes following test types: • automatic test • manual test • test of electricity meter constant verification (dial test) • maximum test • data input from a handheld terminal (input of serial numbers, dial final states, arbitrary user text) 3.3.1 Automatic Test Result of an automatic test is directly a value of electricity meter error in percentage (e.g. -1.23%) and is always provided by OPS. After setting the load point test signals, the computer reads measured individual error values from the OPSs and after completing the test, it automatically evaluates the final meter error by statistical processing of measured values. The automatic test is terminated upon user's instruction in adjustment mode (by pressing the start button or from the program menu) or, in verification mode, after the specified number of samples being measured.

3.3.2 Manual Test Manual test is expected to have a logical character (with "Pass" or "Fail" result type). The test result is obtained manually from the operator or automatically from the OPS evaluation unit operating in a special mode. Test evaluation OPS After running the test, the load point for the given test is generated. This type of evaluation can operate in two approaches (using one is not excluding the other): a) Manual evaluation: OPSs display text "YES" indicating positive (Pass) test result. By means of the OPS button it is possible to change the pre-set state to "NO" indicating negative (Fail) result of a test. After the time necessary for the test to elapse and the results are entered via OPS evaluation buttons, operator can terminate the test. b) Automatic evaluation: The choice of this type of evaluation of starting current test and no load test allows evaluating these tests without the necessity of operator’s intervention, however still possible. The evaluation unit scans the flashing of LED (for static electricity meters) or movement of the disk (for dynamic electricity meters). Based on the number of flashes or the number of disk rotations it evaluates the test while taking into account the marginal number of flashes or rotations set in the program parameters. After starting the test, the load point for the given test is generated. The OPS units display text “CNT”. After finishing the test (necessary time for the test elapses or it is terminated by an operator) the program automatically evaluates the test.
Evaluation using terminal (HHU): After starting the test, the load point for the given test is generated. After necessary time for the test to elapse, the operator enters the test result (Pass/Fail) for each position into the handheld terminal manually. After test completion, the operator is prompted to load the test results from the handheld terminal into the computer. Manual evaluation using a PC After starting the test, a load point for the given test is generated by the system. After defined time expiration operator terminates the test manually, afterwards the program prompts the operator to evaluate individual positions by opening the window "Manual Input". In this window, the operator individually evaluates logical states for all positions.
3.3.3 Dial Test The electricity meter constant verification (dial test) is used for verification of correct dial performance (in case of multi-rate meters, all dials consecutively) and thereby for verification of electricity meter’s constant. The amount of generated energy (or time) is specified at the test definition in the measurements database either by a direct entry of dosed energy quantity in kWh or by entering the time in minutes.

ELMA - Control System User‘s Guide
Test evaluation Manual evaluation using a PC (Manual from PC) After starting the test, the operator is prompted to load the initial dial status data from the handheld terminal. After the data are loaded, the energy flow is initiated. When the predefined energy volume is depleted, the operator is prompted to load the final dial states from the handheld terminal. When they are uploaded, the window "Manual Input Data" appears. Here the operator evaluates manually each measurement position according to the displayed initial and final states. Manual evaluation using OPS evaluation units (Manual from OPS) After starting the test, the operator is prompted to load the initial dial states from the handheld terminal. After loading, OPS units display consecutively the final states, calculated from the initial states and energy batch size. Consequently, energy batch load is initiated. When energy batch load is terminated, the operator is prompted to evaluate individual meters by pressing a button of the OPS evaluation unit at the respective measured position. The operator has to find out himself the deviation of the dials’ current states from the states displayed at the OPS units and to determine the logical result (Pass/Fail) for all meters. By pressing a button at positions with a Fail result, the operator informs the computer which meters passed and which failed the test. Automatic evaluation The test is evaluated automatically from the uploaded values of initial and final states. It is also possible to consider the result of the automatic test, which has been performed in the same load point. Eventually it is possible to enable meter error measurement during dosing of energy (during dial test). The dial error is then calculated using the following formula:
FINAL − INITIAL − ENERGY RESULT = .100 ENERGY The electricity meter passed if: RESULT +U ACCURACY
and simultaneously when considering meter error measured in same load point: RESULT − ERROR LIMIT
and ERROR +U LIMIT err err where: INITIAL dial state before the test FINAL dial state after the test ENERGY energy volume ERROR electricity meter error measured at the given load point (only if to be considered and already measured; otherwise ERROR = 0) U uncertainty of measurement of energy (coverage factor k=2) Uerr uncertainty of measurement of meter error (coverage factor k=2) ACCURACY accuracy of meter LIMIT limit for dial error (entered into program parameters) LIMITerr limit for meter error (from tolerance table)
At start the operator is prompted to load the initial data. Subsequently, batch energy load is initiated. After batch energy load is terminated, the operator is prompted to upload the final states. When done, the test is evaluated. The test type, evaluation type, consideration of the result of respective automatic test and error limit are defined in the program measurements database.

ELMA - Control System User‘s Guide
3.3.4 Maximum Test The maximum test is used for verification of correct measurement of maximums of meters. Load point of the test and test measurement period are defined in measurements database.
Test evaluation Using OPS evaluation units When the test is completed, operator is prompted to evaluate the test using OPS buttons. Each button press changes the state from "YES" to "NO" and vice versa. Using those states, the computer is capable of evaluating the test. Using hand-held terminal (HHU) After applying dose of power program will prompt the operator to enter maximum indicator states to hand-held terminal. Data entered to hand-held terminal are transferred to PC and used for calculation and evaluation of the test. Program will calculate error of maximum test for each meter under the test. Resulting error is in percentage and is calculated by the formula:
MAX − MAX RESULT = elmer etal .100 MAX etal where: MAXelmer maximum measured by meter under the test MAXetal maximum measured by reference standard of ELMA system Meter passes the test when the absolute value of result is less or equal to accuracy of meter. System evaluation by a PC When the test is finished, the operator is prompted to load the resulting measurement data from a handheld terminal. PC evaluates the complete test automatically.
When optical communication heads are used PC evaluates the complete test automatically. For static meters with supported communication protocols registers readout is used to check the internal values. User evaluation by a PC When the test is finished, the operator is prompted to evaluate the test in PC’s window "Manual Input Data" to evaluate each measurement position manually. 3.3.5 Parameterization Tests These types of tests are for meters equipped with optical interface for communication. Details are described in chapter “8 Data Exchange with (p. 125)”.

3.3.6 Special tests This type of test is used for electronic (static) meters. There are several modes of this test: Compare HHU data with meter display data This is used for visual test of displaying data on the meter display. Data transferred to HHU are visually compared by operator with data displayed on meter’s display. Data transferred to HHU are results of up to three tests executed in measurement. After running the test; program will show window “Results upload to HHU”. In this window it is required to choose three tests which results will be uploaded to hand-held terminal HHU. Use drag & drop method to add test names to bottom box. In case of dial test final states of counter are transmitted to HHU. Upload process is activated by pressing the “Send to HHU” button. After communication OPSs will show text “YES” on their displays (indicating pass state for meter). By pressing the OPS button it is possible to switch state for desired position to “NO”. In terminal HHU it is required to activate “View window” with results for each position. Operator should compare results in HHU with results on display of meter for each position in case of data mismatch should sign position as bad by pressing OPS button to show text “NO”. When there is no need to upload data to HHU this step can be bypassed by pressing “Skip” button.
Compare registers with data in HHU This test provides possibilities for comparison of data read from meter’s registers with data collected by a hand-held terminal HHU. For example, it is possible to compare serial number stored in registers with serial number displayed on meter label. This test requires prior executed test of reading registers. After starting this test program will prompt operator to enter data from terminal HHU.
Type of registers and data for comparison are defined in details of this test (Database of Measurements). When data from HHU and registers match, given position will pass the test.

ELMA - Control System User‘s Guide
Compare register content with specified data This type of test is used for verification of data from meter registers. This test requires executed test of reading registers. Parameters of this test are defined in Database of Measurements.
Compare register content with Reference Standard This type of test is used for verification of values read from meter registers with values measured by Reference Standard and result is evaluated with optional evaluation limit (class of meter is used if omitted).
Compare results of 2 tests This type of test is used for comparison of two tests results. Only tests with string result can be compared. It means following test types: • EM serial number • EM type • EM user text Tests to be compared are identified by their Codes. Test to be compared must be finished prior to running comparison test. It is possible to reject characters from the beginning or end of the string from comparison by defining their count in the definition of the test. Result of such test is 1 (or +) when strings are equal, otherwise 0 (or -).

3.3.7 Data Input from a Handheld Terminal
Data input from a handheld terminal is necessary when performing the following activities: • serial number test • electricity meter type test • final states test • user text load test • constant verification test • maximum measurement test Loading data from a handheld terminal is performed in a "Terminal Input selection" dialogue window. Depending on test type, this window displays individual items which have to be loaded from the handheld terminal. Only items with the checkbox enabled will be loaded. Each box represents one rollup list which, when expanded, lists the tests available in the active databank of the handheld terminal. Therefore, data from the test stored in a handheld terminal chosen from the rollup list will be loaded into the item with a marked checkbox. This method is used to load, for example, the serial number into the electricity meter type. The data from a single handheld terminal are stored in the PC in special file. If the "Use data from the previous communication" checkbox is enabled, pressing the "Load" button will load the data from a file already created in a PC and containing data from previous communication with handheld terminal. If it is needed to load data directly from the handheld terminal, leave this field blank. Pressing the "Load" button will, in this case, display a window prompting the operator to insert the handheld terminal into the docking holster. After inserting the handheld terminal with its program in idle state you can start communication by pressing the "OK" button. The ELMA program is capable to communicate with several handheld terminals. The configuration of the number of terminals and the number of docking holsters is set up in the program parameters in the "Hand-held units" tab. Possible configurations: single communication terminal - single handheld terminal single communication terminal - several handheld terminals multiple communication stations - several handheld terminals This setup determines program communication with handheld terminals as well as with the operator. Only the required tests data are transferred from handheld terminal. In addition, you can set up transfer of modifications only, i.e. of data not yet transferred into the PC. This setup is located in program parameters, in the "Hand-held units" tab. Exclusive transfer of modifications only has to be used when loading data from several terminals. If the "Read register values from text file" checkbox is enabled, pressing the "Load" button will display a window prompting the operator to load the file from a PC containing register values.

Electricity meter type filtering The program allows filtering from the electricity meter type database some types so as to make the menu shorter and more transparent when selecting the needed type of electricity meter in the main program window. This is important especially for those stations where large quantities of electricity meter types are defined and moreover several types are similar and differ only in minor details. Filter is available through context menu (by clicking the right mouse button) in the main program window on the dropdown list of available electricity meter types. A list of available options appears so it is possible to select various options. When selected the dropdown list of available meter types will immediately modify accordingly. This context menu is available only when dropdown list is not shaded (typically when no results are measured yet). The context menu displays several items which you can use to set the required filtering of the offered electricity meter types: • "All types" – clearing all filters (displays all types) • wiring type items ("3P4W, 3P3W", ... "1P2W") • construction type items ("Inductive" and "Static") • connection type items ("Direct", "Half direct" and "Indirect (CT/VT)") • measurement type items ("Active Energy", "Reactive Energy" and “4- Quadrant”) • tariff items ("Tariff 1" - " Tariff 4")
Any of these items can be set (by mouse click) in any combination with other options. For example it is possible to filter all electricity meters measuring (also) tariffs 2 and 3 by selecting the next to last or the one which is before the next to last item in the context menu. You can cancel all filters by selecting "All types". If right mouse click is made upon any parameter from the table beneath “Electr. meters” button, “Configure items” button will appear. Clicking on it opens “Electricity meter type parameters”. This allows showing / hiding parameters in the given table.

4.2.5 Tests Menu The tests menu is located under the start-up bar, right from both rollup menus. This window contains a list of all tests of selected measurement. In each window line, several parameters of these tests are displayed. These parameters (such as test status icon with test name, number of samples, test time (min), etc.) are presented in columns which can be enabled or disabled by user and their sequence can be also changed. In front of the name of each test there is a small icon displaying the test status.
Summary or all possible combinations of test status icons: - (blue arrow) - test in progress - (yellow square) - test to be entered into protocol, not done yet - (light green square) - manual test to be entered into protocol, not done yet - (grey square) - test not to be entered into protocol (usually some parametric tests), not done yet - (yellow square with red check mark) - test to be entered into protocol, already done and evaluated - (grey square with red check mark) - test not to be entered into protocol, already done and evaluated - (yellow square with sky-blue check mark) - test to be entered into protocol, already done but still not evaluated - (grey square with sky-blue check mark) - test not to be entered into protocol, already done but still not evaluated - (yellow square with red check mark and exclamation mark) - test to be entered into protocol, done with errors - (grey square with red check mark and exclamation mark) - test not to be entered into protocol, done with errors The window is also used to run the tests in the following ways: • by double-clicking the line with the required test • by highlighting the line with the required test (using the keyboard arrow keys or the mouse) and subsequently pressing the verification / adjustment start button or ENTER key on a keyboard

4.2.6 Stands Window The Stands window is the largest part of main window located in its center. It is used to inform the operator about measurement progress on respective measuring positions of attached stands. The Stands window has a number of tabs between which can be switched via keyboard (ESC, F1, F2 keys etc.) or by clicking with the mouse at respective tabs located under the Stands window.
In Total and stands tab it is possible to do activation, deactivation or “activation as not used” for the selected measured positions or group thereof. Deactivation of the measured positions is necessary if the number of measured electricity meters is smaller than the total number of measured positions of the whole system. By deactivating a measured position the program receives an information saying, that there is no electricity meter on the given position, which would be actually connected to the current and voltage circuit. In such case the program does not take into account the impedance of the electricity meter on the given position when setting the correct range of the electronic source, and it also does not activate the OPS unit on the given position. Activation of the measured position as not used is required, if it is necessary to measure only part of the connected electricity meters, or there is a need to exclude electricity meter from measurement although it will remain connected. In this case the program takes into account the impedance of the electricity meter on the given position when setting the correct range of the electronic source, but it does not activate the OPS unit on the given position while measure. There are two similar tabs: • Total with All stands view • individual Stands with detailed view
www.appliedp.com ELMASW-UG160-EN 27
ELMA - Control System User‘s Guide
Total tab (All stands) displays all positions Individual stand’s tab displays all positions per regardless of its state (activated, deactivated, stand with their particular state (activated, etc.) During test it shows various icons per deactivated, etc.) along with sample error during positions with different meanings, see below. It test. It also displays measured samples per test also displays measured samples per test per per position when test in progress. position when test in progress:
The summary view is displayed in each Stand window for each measuring position its state at all the attached system rack by means of a small icon. Displayed are the following states: Deactivated measured position: (empty square) - deactivated measuring position Active measured positions which are not used:
- (letter R with grey background) - active not used measured position, with the OPS unit in Ready state Active measured points:
- (letter R with orange background) - OPS unit in Ready state - (letters BG) - OPS unit in Bargraph state - (letter M) - OPS unit in Meas state - (letter C) - OPS unit in Calib state - (letters PAR) - OPS unit in Copy state - parameterization via optical communication - (letters CNT) - OPS unit in Counter state - impulse counting state - (large question mark) - error in communication with the OPS unit - (large exclamation mark) - sensor did not capture the mark - incorrect value - (black plus sign on green background) -meter has a positive error within tolerance - (black minus sign on green background) -meter has a negative error within tolerance - (black plus sign on red background) -meter has a positive error out of tolerance

- (black minus sign on red background) -meter has a negative error out of tolerance - (green plus sign on grey background) -meter measurement ended with a preliminary resulting positive error within tolerance - (green minus sign on grey background) -meter measurement ended with a preliminary resulting negative error within tolerance - (red plus sign on grey background) -meter measurement ended with a preliminary resulting positive error within tolerance - (red minus sign on grey background) -meter measurement ended with a preliminary resulting negative error out of tolerance - (black plus sign on green background with a small exclamation mark) - meter has a positive error within tolerance and the condition of increased result variation is fulfilled - (black minus sign on green background with a small exclamation mark) - meter has a negative error within tolerance and the condition of increased result variation is fulfilled - (black plus sign on red background with a small exclamation mark) -meter has a positive error out of tolerance and the condition of increased result variation is fulfilled - (black minus on red background with a small exclamation mark) - meter has a negative error out of tolerance and the condition of increased result variation is fulfilled The last four errors are displayed only if “Elevated swing of samples indication” is allowed in the program parameters (Measurement - Automatic test). In detail view of each stand window the measuring positions with symbolic indication are displayed as following:
- (no picture) - measuring position is inactive
- (picture of an electricity meter) - measuring position is active
- (struck out picture of an electricity meter) - measuring position active as not used
Deactivation or Activation as Not Used of particular positions can be carried out even when a test is in progress (only in stand view on Main Screen). Using context menu it is allowed to disable any meter, however it is not possible to reactivate such meter during test in progress. This feature is helpful in situations when some meter or its position goes malfunction but the rest of them can proceed with testing. During an automatic test it is possible, in the detail mode view, to detect the actual error of the electricity meter for each position. If the program allows setting up stand types, the detail view displays also the type for each stand. The stand type information in case of using multiple systems must be given into the program to achieve correct setup of electronic power source ranges. Selection of activation type for the measuring position can be performed in several levels: • selection of activation type for a single measuring position - through context menu displayed after clicking the right mouse button in detail view at appropriate electricity meter picture • selection of activation type for a part of a stand - through context menu displayed after clicking the right mouse button in detail view on a panel grouping numerous measuring positions (in most cases, a half of stand) • selection of activation type for the whole bench - through context menu displayed after clicking the right mouse button in detail view out of the panel grouping numerous measurement positions

ELMA - Control System User‘s Guide
• selection of activation type for all stands - through context menu displayed after clicking the right mouse button in the summary view
“Set meter error dispersion” is for internal use only and is available only in demo mode.
During running test context menu upon particular enabled position allows to choose “Restart test on this position”. This is available from Stand’s tab and performs re- initialization of samples. In other words all samples will be deleted and measured from the beginning. This feature is useful if some problem occurred during test start regarding that position and already been resolved. User might not wait until test is done for other enabled positions but rather reinitialize this position. In the end all other positions will be finished but this one will obtain its remaining samples, anyway this feature saves time. Load Point View Load Point view is activated by click on “LP” tab. This window displays values of quantities generated by a Signal Generator and measured by a Reference Standard.

4.2.7 Information Line The information line can be seen only under certain circumstances (during measurement) and is located in the lower part of the main window at its right edge, under the stands region and above the status bar. It consists of numerous individual parts, each of them having its specific usage.
2 1
The current program version uses the following parts of the information line: • the first part from the right - time indicator 1 • the second part from the right - progress indicator • the third part form the right - back control indicator 2 The time indicator informs the user about duration of the test in process, of warming-up or calibration of the sensors. The indicator is located at right edge of the information line. Displayed time format is mm:ss (e.g. 01:23) - if the time is shorter than 60 minutes h:mm:ss (e.g. 1:23:45) - if the time is longer than 60 minutes The indicator is normally in a mode of displaying time elapsed from launching the test or other operation and it is displayed in the information line only. However, also some extended modes of time display are accessible through the context menu displayed after clicking the right mouse button on this indicator: • display of time also in a separate window, the location and size of which and thereof derived size of digits provide the user with a good survey of test duration also from a larger distance from the monitor. The user can arbitrarily customize the location and size of this window and he can cancel this window by standard method anytime.

• display of time countdown starting from the value entered in this menu (e.g. if the entered countdown value is 20:00, the program will count down from 20 minutes downwards). When the value 00:00 is achieved, the program notifies the user by a sound alert and, until the test or other operation is completed (automatically or upon user initiation), the program will continue the countdown by transition into negative time values, i.e. 00:00 will be followed by -00:01, -00:02 etc. The program remembers the display mode and placement of a possible individual window on the screen for each test type (automatic test, manual test, dial test, maximum test, optical readout of the electricity meter registers, OPS unit calibration and warm-up), and these data are stored also after program shuts down. Progress indicator informs the user about the state of subsequent sample readings from measuring positions during an automatic test. The indicator is located left from the time indicator. The form of the progress displayed is: X / C resp. N - X / C - automatic verification test X / ( C ) resp. N - X / (C) - automatic adjustment test P% - mm:ss - dial or maximum test with the following meaning of individual parts: N - minimum number of samples read at all active measuring positions X - maximum number of samples read at all active measuring positions C - required number of samples read for the test currently in process, P% - percentage representation of elapsed portion of the test, mm:ss - number of minutes and seconds remaining till the end of test. If the minimum and maximum number of the samples read equals, only one of those numbers is displayed. In the adjustment mode, the required number of the samples read is enclosed in brackets, because (on contrary to the verification mode) achieving this number is not a condition of automatic termination of the test. Back control indicator informs the user of voltage and current in the system, measured by reference standard (RS) and processed by the program back check. The back control acquires backward system information from a reference gauge (RS) and from an electronic source. From this information the two most important quantities (voltage and current) are displayed, in individual phases, in the part of information line reserved for the back control indicator. Values of further quantities obtained during the process can be displayed by activating a separate back control window, using the context menu which displays after right-clicking this indicator. The separate back control window displays the following quantities: • voltage, current and phases of the electronic source (the Signal Generator device), • the basic reference’s quantities: voltage, current, phase and frequency, • some additional gauge quantities: active power, reactive power and some other. The additional quantities of the reference are visible only when this window height is sufficiently large. The program stores this window display mode and placement on the screen for each test type (automatic test, manual test, dial test, maximum test, optical readout of the electricity meter registers, OPS unit calibration and warm-up), and these data are stored also after program termination. The quantities as voltage, current and phase are displayed in colour (other than black), if their inspection is turned on in the program settings. According to the defined boundary values, green colour indicates that everything is OK for the given parameter; yellow colour indicates that the lower boundary has been exceeded, and red colour warns that the upper (critical) boundary has been exceeded. 4.2.8 Status Bar The status bar is located in the lowest part of the main window and spans its whole width. It displays miscellaneous useful information for the program user. The status bar is split into a number of parts, each of them having its specific usage. Recent program version uses following parts of the status bar:

4.3 Information Window The information window appears after choosing the item "Help / About program" in program menu or after mouse double clicking on the logo located in the right upper edge of the main window. In this window, it is possible to identify the recent program version.
4.4 Results Window The results window is displayed by pressing the respective activation button, from the program menu, using F5 or Ctrl + R keyboard shortcut.
In this window, test results for meters at individual positions are displayed. After performing any test, here you can find the results of tests already done. The window includes the following buttons: • the OK button closes the window • the Delete button clears the results of all tests. It is used after the measurement is finished (all the tests done) as well as the necessary operations with the protocol (generation, printout, archiving). After removal of all results, it is possible to start measure the same measurement with a new batch of meters or to change the electricity meter type or to change measurement as well (if all the test results of the current measurement are not erased at the time of change of measurement type or electricity meter type in the main window, this type of change is allowed only after confirming of deleting all test results). • the Protocol button starts the process of protocol generation and printout associated with archiving of measured test results • the Details button displays data read from registers of static electricity meters. These data are displayed in additional window, if the register readout test cell in the results window is selected and the given electricity meter has been read.

• the arrow keys are used for horizontal display shift of a number of positions depending on the window size. Those two arrows may be controlled also via plus and minus keys of the numerical part of the PC keyboard. In the results window each position with an electricity meter which did not pass the test is marked with red color and number sign # (hash). The program checks serial numbers with each opening of the results window. If it finds same serial numbers in several fields, they will be displayed in red color. While there are duplicate serial numbers, it will not be possible to continue with protocol printing after pressing the Protocol button (window with following message will be displayed: “Protocol printing not possible - duplicate serial numbers”). The highlighted serial number can be changed by double-clicking it. New window will be displayed, where you can enter a new serial number.

4.5 Manual Control Manual Control allows controlling of Power Source (Signal Generator) without defining tests and measurements. This feature is accessible through menu System – Manual Control. Main purpose is to allow user to easily define all essential parameters such as frequency, meter constant, voltage, current, phase angle etc. Seeing also the values from Reference Standard (Measured Values in top right corner) helps quickly evaluate the outcome. “Individual” checkbox - if unchecked allows to control all 3phase controllers per quantity.
In voltage and current section user defines maximum values and then using the color bars set percentage of the maximum value per individual (if checked in top) channel. Small timeout (2-3 seconds) is applied after each change in this window to enable change of more quantities in one batch before applying to Signal Generator in case when Power Source is not in standby state (voltage and/or current are generated).
4.6 Program Parameters Window The parameters window can be activated in the main window from the program menu. The window consists of multiple tabs: • Service (this page is accessible in service mode only) • Measurement • Evaluation • Hand-held units • Protocols • OPS • Back control • External Software All those pages use three common buttons: • OK confirming changes and quitting the window • Cancel discard changes and quitting the window • Apply confirming changes without quitting the window

Automatic test This field is used to set up parameters for automatic tests. It contains these parameters: Use last sample in adjusting mode It toggles on/off automatic test termination in the verification mode after measuring the specified number of samples (if switched off, the test must be terminated by the user using a button). Elevated swing of sample indication It toggles on/off indication of increased oscillations of the measured samples. If switched on, it is possible to define the limit at which the display will be indicated. Measurements timeouts First sample + All other samples Defines the maximum waiting time for error sample. Timeout algorithm Defines the algorithm for calculating the maximum waiting time. After error detection wait additional Defines the time in seconds to wait for error sample, when the test is finished, but no sample was detected. The ‘Error’ message on yellow background is shown on this position during this period.
Manual test The field is used for parameters setup for manual tests. External test If checked, the manual tests are considered as external (made in another equipment). Evaluation This field is accessible for internal tests only. The external manual tests are always evaluated by read- in of data from the handheld terminal. OPS For static electricity meters, choosing this type of evaluation selects automatic test evaluation in form of scanning the number of the electricity meter LED flashes, while taking into account the boundary number of flashes set in the test parameters. For dynamic electricity meters it is possible to choose between manual or automatic evaluation via OPS.

ELMA - Control System User‘s Guide
In case of manual evaluation of dynamic electricity meters, the test for each position is evaluated individually using a button on the OPS. By pressing this button the text on the display changes to either „YES“ (pass) or „NO“ (fail). Automatic evaluation of dynamic electricity meters is available only when the software and hardware of the whole system allows it - only then the detection of disk movement is available, which allows to turn on the automatic test evaluation. In such case, test is evaluated automatically based on detected disc movement, with respect to the boundary number of revolutions set in the test parameters. HHU For test evaluation, data input at the handheld terminal are used. PC The manual test is evaluated by the operator directly in displayed program window. The operator enters for each position the electricity meter state for given test (pass/fail). Dialogs with magnetic mover This parameter specifies whether the dialog window for moving the disk mark into the initial position should be displayed. The disk is moved with optional solder iron at the beginning of starting current test and no load test. Automatic test finishing This parameter specifies whether the manual tests have to be terminated automatically after the time pre-set in the test parameters elapses. Show last mark period If enabled, the parameter ‘Last mark period’ is shown in the bubble help of manual test in the Results window. This period means the interval between 2 last flashes of the LED. Enable concurrent tests If enabled, the parallel tests are allowed in blocks of tests, available only for Dial test and Maximum demand test. Starting current test Test duration calculated from first LED flash This parameter specifies time measurement of given test starting from first LED flash. This means, that time before first LED flash will be ignored. Impulse counting starts after first LED flash This parameter specifies impulse counting of given test starting from first LED flash. This means, that first LED flash will be ignored.

Dial Test (Constant verification test) The field contains parameters, which are used for constant verification test setup. Evaluation External For external tests only. Handheld terminal data are necessary for evaluation. Data contain the entered logical Pass/Fail states for individual positions. Therefore, read-in of test results from the terminal is obligatory, read-in of the dial states before and after the constant test verification is optional. Manual from PC For internal tests only. The operator evaluates the meters directly in the program window by choosing Pass/Fail result based on comparing the dial states before and after the test. Reading dial states is not obligatory; however, if they are not read they will be either not displayed in the window to be evaluated by the operator. Manual from OPS For internal tests only. The operator evaluates the meters manually by means of the individual OPS buttons. Pressing the button, two states of the OPS unit are switched. The actual state is shown on the display. If reading-in of initial dial states from a handheld terminal is allowed, display of the calculated final state (meaning Pass) is switched over with a "NO" text (meaning Fail). If the initial states were not read in, the text "YES" (Pass) and "NO" (Fail) are being switched over. Automatic The test is evaluated by calculating the dial error from dial states before and after the test. If the dial error is smaller than the limit entered, the electricity meter passed. The check box "Consider load point results" adjusts dial error calculation so that the calculation includes measured error of the automatic test in the same loading point as the constant verification test is performed. For automatic test evaluation, read-in of dial states before and after the test is required. Reading Data from the HHU Determines the items, which have to be read from handheld terminal. Corrections Power correction It toggles on/off the energy batch duration compensation with respect to the actual output power level. Time correction Time correction of dosage given in seconds. The Parameter Allow batch changing enables or disables the batch size change, when starting of test.

Maximum demand test The field is used to set up parameters for the maximum test. External test Used to setup the test type. If this field is checked, tests are considered external. Also the other field items adapt to the state of the checking parameter „Extern“. Evaluation This field is accessible for internal tests only. External manual tests are always evaluated by reading in the data from the handheld terminal. OPS The operator evaluates the test by means of a button on OPS unit for each position. By pressing the button, „YES“ (pass), „NO“ (fail) printouts switch over the display. HHU Data entered via the handheld terminal are used to evaluate the test. PC (system evaluation) The test is evaluated automatically by computer after reading in the numeric results of meters from the handheld terminal. PC (user evaluation) The test is evaluated by operator directly in the displayed program window. Operator enters result state at each position for given test (pass/fail). Use before test status If enabled, the test is evaluated as difference of register value at the end and at the start of the test, otherwise the maximum value at the end of test is evaluated.
Data exchange test The field is used for parameters setup for data exchange test between electricity meter and computer, i.e. to read out the registers of static meters. Extern test Used to set up the test type. If the field is checked, the tests are considered external. Also the other field items adapt to the „Extern test“ check parameter. Accept higher baudrate This parameter specifies whether during readout via OPS also higher communication speed, different from the standard, can be used, if the electricity meter allows this.

Initial Baudrate [bps] Standard communication speed can be changed in this field. Default speed is 300 baud. Manual input of register values when optical communication fails If enabled, ELMA automatically offers the manual input of values to the operator, if the optical communication fails. Use parallel communication if enabled in test properties This parameter allows the parallel communication on all positions, if it is allowed in the test properties.
End state test The field „End state test“ is used to set up the parameters of the final states test. Load from dial test Enables read-in of dial states after the constant verification test into final states. That means, after the dial test, the final states are filled-in, too. Evaluation This field is accessible for internal tests only. External manual tests are always evaluated by reading in the data from the handheld terminal. Rounding Active Used for activation of rounding of the final state values. If the rounding is active, also other items of the „End state test“ field are accessible. Position Specifies the number of digits for which rounding is active 100 rounding to hundreds 10 rounding to tens 1 rounding to an integer 0.1 rounding to one decimal point 0.01 rounding to two decimal points System Choice of rounding method. It is possible to round upwards, downwards and in a standard way.

This page contains parameters influencing display and evaluation of measurement’s results: • parameter 1 allowing to switch on/off graphic evaluation after automatic test completion • parameter 2 allowing to switch on/off checking for all defined measurement’s tests before printing the protocol or archiving the results • parameter 3 allowing to switch on/off the possibility of phase to phase voltage input in the database of electricity meters, if the current database version allows this
• parameter 4 allowing to choose the type of uncertainties: o none o fixed uncertainty (usage of selected table from database of uncertainties) o calculated uncertainty according to EA-4/02 document with definable “k” parameter (the remaining two parameters Chi and Zmax are defined on the service page) o using special formula o uncertainty set according to EN 62058-31 • Parameter “Adjust error according to Power Factor” - if enabled, the raw/measured error value is multiplied with Power Factor of the loadpoint. Then both values are present in the bubble help of ‘Results’ window.(the measured value in square brackets) • Parameter “Allow error values recalculation from Result Window” - allows to switch between these two values(see previous parameter) in the ‘Results’ window using checkbox ‘Values related to Power Factor’. • Parameter “Use System Of Asymmetric Tolerances” - it enables the system of asymmetric tolerances (limits) for evaluation of tests - more information you can find in the chapter 5.3 Database of Tolerances (p. 95) • Parameter “Use System Of Multiple Tolerance Bands” 5 - it enables the system of multiple tolerance bands for evaluation of tests - more information you can find in the chapter 5.3 Database of Tolerances (p. 95) • Parameter “Special Evaluation” 6 enables special evaluation of test - currently implemented as demonstration version - subject to changes in near future • Parameter “Enable Selective Filtering of Electricity Meter Types (or Measurements)” 7 enables using “Include In List” option in Electricity meters’ database (or Measurements’ database). This switch, if unchecked, hides given meter type (or measurement) from the list in program’s main screen rollup. • Parameters of “Average test error” - allows to set the average test error calculation, e.g. if the data from bad positions or results outside tolerances should be included into the average error. Moreover allows to exclude special errors with value 99.99% from average test error calculation.

• Parameters of “Average position error” - allows to set the average position error calculation, that means allows to exclude special errors with value 99.99% from average position error calculation. • Parameter “Show good / bad position count in results window header” - enables showing the good/bad position count in the header of the ‘Results’ window. • Parameter 8 allowing to switch on/off filtering of measured samples. If filtering is switched on, it is possible to define criteria 9, 10 and 11 for samples rejection. Filtration consists of two steps: o 1st STEP: User defined number of initial samples is rejected. Number of rejected samples can be specified either by (global) parameter 11 or in test properties. The setting in test properties has higher priority than global setting. Count of automatically rejected initial samples 11 – defines number of unconditionally rejected initial samples during different type of tests: cosines tests (tests with power factor other than 1), tests with low currents, tests with higher currents and remaining tests. These samples are not counted to limit specified in parameter 9. Even if parameter 9 is zero and count of automatically rejected input samples is one, one sample will be rejected (it will not appear in results and it will not influence the calculation of average or standard deviation of result). If number of raw measured samples is less than or equal to parameter 11, all raw measured samples will be rejected and test on specified position will fail (user will see in result special value defined in application configuration, most probably 99.99%). o 2nd STEP: Outliers are detected by iterative method: In every iteration first a dataset average AVG(n) and standard deviation STDEV(N) is computed. Next the absolute deviation between each data point and the average is determined. Then most extreme point is temporarily removed from dataset. Average AVG(N-1) and standard deviation of dataset STDEV(N-1) are calculated. If the ratio STDEV(N) / STDEV(N-1) is less than first part of criteria 10 and STDEV(N-1) is less then second part of criteria 10 iteration algorithm terminates. If this condition is not satisfied (for example because STDEV(N-1) equals or is more than second part of criteria 10), most extreme value is (permanently) deleted from dataset and next iteration of algorithm is started. The maximum number of samples rejected in step 2 is determined by parameter 9. For example if allowed number of rejected samples is set to 19% and dataset after step 1 contains 5 points, no sample can be rejected in step 2 irrespectively of dataset distribution. The algorithm stops also in case when number of samples in dataset equals 3 (so there will be at least 3 samples after step 2 from which final average and standard deviation will be calculated).

Resolution 1 This item enables to toggle high / low resolution of displaying the measured meters error. High resolution means displaying the measured meters error on 3 decimal places on OPS units’ displays and in ELMA control software. Otherwise Standard Resolution will be used - error will be displayed on 2 decimal places and resolution will be 0.01%. We recommend using Standard Resolution for testing meters with classes up to 0.2. High resolution should be used for measuring reference standards. Evaluation window switch 2 This field allows switching on/off the measurement window of OPS units (this measurement window specifies the maximum electricity meter error in both positive and negative direction from zero, measurable by OPS unit at its given setup). Separately for adjustment and separately for test it is possible to define for electronic and for electromechanical meters independent values of the measurement window of evaluation OPS units. For static meters, the size of this window can be set up to maximum. We recommend using max. window size in all cases.

To evaluate automatic tests, the program has to know for each load point the allowed limits of percentage errors. Limits depend on precision class of given electricity meter type. The allowed percentage error limits are exactly specified in the standards concerning electricity meter verification. Verified electricity meter fulfils the requirements for given precision class if in every tested point the absolute value of error increased by the expanded uncertainty is lower than the limits of percentage specified in the table. The expanded uncertainty uses expansion coefficient kU = 2. The program allows generating and editing the tables of allowed percentage errors. Each table should contain a set of load points in which verification of given electricity meter type together with specified limits of allowed percentage errors for individual precision classes is performed. Using program it is possible to create any number of tolerance tables 1. Each tolerance table is stored in an individual database file. For each measurement from the measurements’ database the selected tolerance table is used for evaluation of results. Editing and maintenance of toleration tables is accessible from the „Database“ - „Tolerances“ menu. In the left side of the window, a list of already created tolerance tables is located. Highlighted line indicates the tolerance table the parameters of which can be found in the table right from the list 2. Selecting (highlighting) of particular tolerance table can be performed by mouse click or by buttons under the list. When System of Asymmetric Tolerances is enabled (“Parameters - “Evaluation” Tab - “Use System of Asymmetric Tolerances”) on the right side from column “Tolerance” there will be a column “-Toler” 3 for entering lower boundary of tolerance. When System of Multiple Tolerance Bands is enabled (“Parameters - “Evaluation” Tab - “Use System of Multiple Tolerance Bands”) in tolerance table will appear additional columns 4 for specifying tolerances for all boundaries. System of bands and boundaries of tolerances is displayed in the following figure:

• symmetrical (0) • asymmetrical (1) • L1 • L2 • L3 Class 4 specifies electricity meter precision class for which the limit of allowed percentage error is specified. Power Factor 5 specifies the power factor of the load point for which a value of allowed percentage error is specified. Current Formula 6 expression with special syntax which specifies the current value of the load point for which a value of allowed percentage error is specified. The syntax format of the current expression is described in the next chapter. Tolerance 7 specifies numerical value of allowed percentage error. 5.3.3 Format for Current Formula Current expression is a string used for identification of given tolerance point. The tolerance points of particular tolerance table are defined as limits of allowed errors for evaluation of automatic tests. The current formula specifies the current value in load point for which the value of allowed percentage error is specified. For purposes of universality and compliance with the standards, current value is specified in relation to nominal or maximum current of the electricity meter being verified. The syntax has 4 possible variations: 1. Current value of the load point must be equal to the specified current: syntax: [k1]P[*] 2. Current value of the load point must be lower or not greater than the specified current: syntax: IZ[k]P[*] 3. Current value of the load point must be greater or not lower than the specified current: syntax: [k]PZI[*] 4. Current value of the load point must fall within the interval: syntax: [k1]P1Z1IZ2[k2]P2[*] symbols used: [] - the rectangular brackets contain optional text k, k1, k2 - multiplication constants P, P1, P2 - current denomination which can have the following values: In - nominal current Imax - maximum current Z, Z1, Z2 - comparison sign: < or <= * - if specified it indicates that the allowed percentage error and its load point is generated only if the values of electricity meter nominal and maximum current are equal. Syntax: [ki]Pi means that the current (nominal or maximum) is multiplied by the value of the ki constant. Examples: 0.1In ... the load point current value must equal to 10% of electricity meter nominal current Imax ... the load point current value must equal to electricity meter maximum current I<2In ... the load point current value must be lower than double electricity meter nominal current I<=2In ... the load point current value must be lower or not greater than double electricity meter nominal current 0.25Imax

The Imax parameter is checked during load point generation. This ensures that Imax will not be exceeded even in case of faulty setup of electricity meter parameters or inappropriate electricity meter/rack combination. 98 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide R [Ohm] 2 Stand’s own resistance without meters. It is necessary for optimal current source output impedance match in order to ensure maximum power output. Current Ratio (prim/sec) 3 It allows to define the ratio of primary against secondary side in case, when current transformer is used in order to achieve higher power (current). Using this ratio the control system (especially RS and SG) “knows” to apply necessary calculations, even if there is lower (higher) power on primary side than on secondary due to unequal number of loops on both sides. Enabled positions 4 Parameter allows an automatic change of position activation after changing a stand: • no change - after the change into the given type, the automatic change of activated positions will not be performed • all - after the change into the given type, all positions will be automatically activated • even - after the change into given the type, all even positions will be automatically activated • odd - after the change into such type of stand, all odd rack positions will be automatically activated • user defined - after the change into given type of stand, all stand positions entered into the text box in the following form, will be automatically activated: 1,2,3,5,8,9,12,18 CMRI 5 This option allows to enable / disable the usage of CMR-I units on the stand. If enabled detection of 1st unit can be set via its communication address. This feature allows to work with mobile stands each mounted with different CMR-I units. 5.4.1 Adding New Stand and Deleting the Stand Adding a new stand to the database is performed by New button. Afterwards, user has to enter data for individual items. Deleting a stand is performed by pressing the Delete button and action confirmation. 5.5 Database of OPS units Addresses 1 2 www.appliedp.com ELMASW-UG160-EN 99 ELMA - Control System User‘s Guide Each OPS evaluation unit is addressed by its unique address within the whole system. The address comprises three bytes. Immediately after powering on, the OPS successively displays: -AP- followed by the highest address byte in hexadecimal format and, after a short pause, the middle and lowest address bytes in hexadecimal format. The OPS addresses valid for positions are stored in the database of addresses. The database of addresses is accessible from the „Database“ - „OPS addresses“ menu. This window contains a table with two columns, „Position“ 1 and „Address“ 2. The position specifies the position name and the address displays the specific address for the position given. The addresses are displayed and entered in hexadecimal format. The addresses with zero lowest byte (e.g. 27FA00h) are reserved for special use and are not accepted by the program. 5.5.1 Address Modification Any address can be edited by double click on item in database. A dialogue window will appear in which user can enter new address for given OPS. If entered address is valid, it is subsequently stored in database of stands. Press „Use“ before closing the window. 5.6 Database of Stations and Equipment 1 2 The database of stations and devices stores information of all measuring stations connected to the system where sharing common databases are applied and to preserve information on equipment which is a part of the system. The database is split into measuring stations part 1 and the devices part 2. A part of the measuring stations preserves the following parameters of every station: • sequential number • name • serial number • type • precision • last verification date 100 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide • last verification validity termination date • note A part of equipment preserves the following parameters of every station: • equipment type (1=POWER ANALYZER, 2=SIGNAL GENERATOR ...) • serial number • type • precision • last verification date • last verification validity termination date • communication address In both parts it is possible to create a new record using „New“ button, to delete chosen record using the „Delete“ button, and to display parameters of the chosen record and optionally change them using the „Details“ button or mouse double-click. The „Save“ button is used to save the performed changes immediately. The „OK“ button closes the database window with saving the changes and the „Cancel“ button closes the database window without saving the changes. 5.7 Database of User Defined Signal Shapes This database defines user signal shapes which can be chosen in test definitions.

Generating and Printing Protocols The program enables user defined design of protocol and automatic generation and print of the output protocols using the MS Word profiting from all of its capabilities. Generating of output protocol is performed by automatic filling-in of measured and calculated output data into the previously created MS Word protocol templates and their subsequent saving in a file with an appropriate name and optional printer output. As a standard, a number of protocol templates is delivered with the program; although, the user has an option of creating custom ones. The protocol templates necessary for generation of the output protocol are automatically generated by the program from the command templates generation of which enables the user to get full control of the final look of the output protocol. When creating command templates, you can take full use of the MS Word program features. 6.1 Using the templates – diagram Protocol Measured and commands, prefix calculated values Command Template generating Generated protocol Template filling template process template process Template protocol filled Printing of protocol with data = Saving of protocol in new document output protocol name 106 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 6.2 Generating and Printing the Output Protocol For output protocol generation is necessary a protocol template which corresponds with the number and types of tests performed in the given measurement. Automatic generation of an output protocol, its saving into file, archiving and printing are activated in the Results window using „Protocol“ button. After pressing this button, „Protocol heading“ is displayed. Here it is possible to fill in necessary protocol heading items. As next, the „Protocol“ window is displayed: 1 2 3 4 5 www.appliedp.com ELMASW-UG160-EN 107 ELMA - Control System User‘s Guide In this window you have to specify whether: • the results have to be saved in the archiving database 1, • the output protocol 2 has to be generated and if so to specify: o protocol template 3 - the name of the template which was specified for the actual measurement in the database of measurements appears here. If it is necessary to use another template it is possible to enter its name or use the „List“ button. o whether the generated output protocol has to be saved automatically into a file with the specified name 4. If the file name does not contain path specification, the file will be saved into a directory for saving MS Word protocols which was defined in the program parameters. o whether the generated output protocol has to be printed from MS Word automatically 5. After pressing the „OK“ button, the chosen operations are executed in the following sequence: • archive of results • generation of output protocol • saving the protocol in a file with specified name • printing the protocol via system printer 6.3 Creating Protocol Template The program can generate the protocol template automatically from previously prepared command template. This is a process in which the command template is gradually scanned and recognized protocol commands are substituted by text fields with bookmarks. Those text fields are later used as marks specifying in course of the program which data have to be written to specified locations. Before starting generation of protocol template it is necessary to start MS Word and open a command template intended for protocol template generation. If there are more files opened in MS Word, the document with command template has to be activated. The process of generation of the command template is launched from main menu „System“ - „Protocol“ - „Creating the Protocol Template“. After activating an information window is opened which shows the progress of generation. After generation is successfully finished it is necessary to save the newly created protocol template in a file with a specific name for later output protocol generation. 6.4 Command Template and Protocol Commands The command template is used as a pattern for automatic creation of protocol template. It is a standard MS Word document and, therefore, during its creation the user can use all MS Word features (for example insert company’s logo, insert tables, change the font, highlight the text etc.). To input the measured and calculated values into the protocol and to specify the type of this data, it is necessary to insert appropriate protocol commands into the document. The commands in the command template are marked by defined command prefix. The pattern is: command prefix + protocol command (e.g. #TEMP). The protocol commands are stored in the database of protocol commands (in the „System“ - „Protocol“ - „Commands“ menu). 108 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 5 3 4 1 2 The protocol commands are listed here in a table in two versions: Default commands 1 are protocol commands that are predefined and cannot be changed by the user directly. User commands 2 are protocol commands which may be customized by the user (localized into his language). The user command may not contain the „_“ character and its maximum length is 10 characters. It is possible to change the command by mouse double click on the line with the particular command and entering a new expression. Each command has its description which may be supplemented and edited. The „Use commands“ 3 option allows to choose which commands will be used for creation of command templates. In the „Command Prefix“ 4 window it is possible to define the command prefix. The predefined character for the prefix is „#“. The „_“ sign is not allowed. In the „Protocol result and status texts“ 5 window region, text strings substituting the evaluation commands (VAL, TSTATUS a STATUS) are defined. Those text strings are defined separately for individual evaluation types and for the cases when the electricity meter passed, failed or was not measured. More detailed description of those commands can be found in further text. In the database of commands, the following commands are implemented: www.appliedp.com ELMASW-UG160-EN 109 ELMA - Control System User‘s Guide Predefined User Command description ANUM ANUM Meter Calibration Number CNTERR CNTERR Register test Error (absolute) COS COS Load point power factor DACT DACT Current date DATE DATE Date DATESEC DATESEC Date 2 DEL DEL Delta -

They are used to mark the blocks associated with individual tests. That means, to display data of the 1st test of the selected measurement, it is convenient to close the 1st test data of the selected measurement into a block using the #TESTxx, #ENDTEST commands: #TEST01 … Commands to display specific data … #ENDTEST The number following the #TEST command specifies the test sequential number within the actual measurement. This number must always be entered as two-digit. The lowest number for #TEST is 01, the highest is 99. 112 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 6.4.1 Rules for Using Commands in Command Template The #TESTxx and #ENDTEST commands are removed in the process of protocol generation. It is convenient to locate them in separate lines which will be then automatically removed. The commands from the commands database are recognized only if they are preceded by a valid prefix. The prefix is recognized up to the nearest white character (the following characters are considered to be a white character in this case: dash, move to next paragraph, tab character, character of moving to another table cell). All command parameters have to follow the command without any white character between them. The command itself must not contain the „_“ character which is reserved to separate the command parameters. The parameters are described in the following sections. 6.4.2 Syntax of Commands used inside #TESTxx … #ENDTEST Blocks Those are the commands concerning display of the measured or calculated values and commands for displaying the load point parameters. However, they always concern one specific test and therefore it is necessary to specify in the template to which test the commands belong. This specification is performed by embedding the mentioned commands into the #TESTxx … #ENDTEST block. The test number can be, however, specified also directly as a command parameter; but in this case the command may not be located in the #TESTxx … #ENDTEST block. Used labels: Pos - position number Test - test number Val - sequential number of the measured value Commands for display load point parameters and test parameters Command Syntax in the #TESTxx …#ENDTEST Syntax outside the #TESTxx block …#ENDTEST block U1 U1 U1test U2 U2 U2test U3 U3 U3 test I1 I1 I1test I2 I2 I2test I3 I3 I3test COS COS COStest CHAR CHAR CHARtest PHU1 PHU1 PHU1test PHU2 PHU2 PHU2test PHU3 PHU3 PHU3test PHI1 PHI1 PHI1test PHI2 PHI2 PHI2test PHI3 PHI3 PHI3test ENERGY ENERGY ENERGYtest SAMPLES SAMPLES SAMPLEStest TARR TARR TARRtest UTARR UTARR UTARRtest TNAME TNAME TNAMEtest TCODE TCODE TCODEtest www.appliedp.com ELMASW-UG160-EN 113 ELMA - Control System User‘s Guide Commands for display of measured values Command Syntax in the #TESTxx …#ENDTEST Syntax outside the #TESTxx block …#ENDTEST block VAL VALpos_val VALpos_test_val POC POCpos POCpos_test KON KONpos KONpos_test SNUM SNUMpos SNUMpos_test Commands for display of calculated values Command Syntax in the #TESTxx …#ENDTEST Syntax outside the #TESTxx block …#ENDTEST block VAL VALpos VALpos_test DEL DELpos DELpos_test DIFF DIFFpos DIFFpos_test UR Urpos URpos_test UA Uapos UApos_test UB Ubpos UBpos_test UC Ucpos UCpos_test TSTATUS TSTATUSpos TSTATUSpos_test TOLER TOLERpos TOLERpos_test 6.4.3 Commands used outside #TESTxx … #ENDTEST Blocks Commands for protocol description and Commands for display of commands for display of the station parameters electricity meter parameters Command Syntax Command Syntax ETYPE ETYPE LISTN LISTN EACCUR EACCUR DATE DATE EUNOM EUNOM DACT DACT EINOM EINOM TEMP TEMP EIMAX EIMAX REM REM ECONST ECONST PERSON1 PERSON1 EFREQ EFREQ PERSON2 PERSON2 EUPROT EUPROT STYPE STYPE EIPROT EIPROT SSNUM SSNUM EFREQPROT EFREQPROT SACCUR SACCUR ENTARR ENTARR SCALNUMB SCALNUMB ENPHASES ENPHASES SCALUNTIL SCALUNTIL ECOUNTD ECOUNTD ZMAX ZMAX ECOUNTM ECOUNTM K K EIMP EIMP CHI CHI EMANUFACT EMANUFACT EIMPPROT EIMPPROT ECALUNTIL ECALUNTIL 114 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide Commands for display of the Power Commands for display of the Signal Analyzer device parameters Generator device parameters Command Syntax Command Syntax PATYPE PATYPE SGTYPE SGTYPE PASNUM PASNUM SGSNUM SGSNUM PAACCUR PAACCUR SGACCUR SGACCUR PACALNUMB PACALNUMB SGCALNUMB SGCALNUMB PACALUNTIL PACALUNTIL SGCALUNTIL SGCALUNTIL Evaluation commands Command Syntax STATUS STATUSpos STATINFO STATINFOpos 6.4.4 Using TSTATUS, STATUS, STATUSINFO Commands The TSTATUS command is used to display the final state of the specified test. The text for the test final state display is entered in the „Commands of protocol formatting“ field in the edit fields „Test Evaluation“. There are three edit fields to enter the test status: pass, fail, test not performed. Afterwards, the TSTATUS value corresponds with the text which complies with the measured test status. TSTATUS is evaluated for the individual test types as follows: Automatic tests The electricity meter passed if the sum of absolute values of the weighted average and expanded uncertainty is lower or equal to the threshold value. The threshold values are specified for the given load point and the electricity meter type from the tolerance table associated to given measurement. Manual tests The electricity meter passed if the operator evaluates the electricity meter as Passed. Special tests The electricity meter passed if the test result passed the condition specified in the tests database for the given test and its respective tolerance point. Constant verification tests In case of manual evaluation of the constant verification test, the electricity meter passed this test if the operator evaluated it as Passed. At automatic evaluation of the constant verification test, the test is evaluated by computer. The evaluation is based on the dial states before and after the test. The STATUS command is used to display the final state of the electricity meter after all tests or the tests required by the operator are performed. The text to display the electricity meter states: pass, fail, was not evaluated, is user-defined in the field „Commands of protocol formatting“ in the „Electricity meter evaluation“ edit fields for all three states. The STATINFO command is used to display a string, which lists the states of all tests for the given electricity meter. The states are displayed sequentially by the test order, just as they are defined in the selected measurement. The individual tests are separated by a comma. The state of individual tests is illustrated by user-defined text defined as text for display of the test final state. www.appliedp.com ELMASW-UG160-EN 115 ELMA - Control System User‘s Guide 6.4.5 Using VAL Command The VAL command is used to display the measured test results. Therefore, it is useful to use the command within the #TESTxx … #ENDTEST block. Syntax: VAL Position number[_Value sequential number] If only the Position number parameter is specified, the command is used to display the following values depending on the type of test the order of which is then specified by the #TEST command parameter: for serial number test electricity meter serial number for final states test final state of the electricity meter dial for manual test the result of the manual test is displayed and the text entered by the user in the „Commands of the formatting protocol“ dialogue window, in three edit fields „Manual test result“, are used. One under the other, the possible text for all the test states is given: pass, fail, the test not performed. Instead of the VAL command, in the process of filling in the protocol the entered text is displayed, corresponding with the test state. for automatic and special test the average error value calculated from series of values measured for the given test are displayed. The average value is calculated from the following formula: 1 n = i n i=1 where: − is the percentage errors selective mean i i is the percentage error obtained from i-th measurement of the series of repeated measurements in the given test point, n is the number of measurements Specification of the sequential number is reasonable only for automatic tests during which specified number of values is measured; those are then used for statistical evaluation of the test. Specified measured value is entered into the protocol. If the test is not automatic and the measured values are specified with their sequential number, blank strings will be displayed at the given positions. The position number as well as the sequential number of the measured value starts with number 1. 116 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 6.4.6 Example of how to Use VAL Command The following example provides displaying values of 5th test in the actual measurement for positions 1, 2, 3, 4. This test is supposed to be automatic. In the column specified as the values of calculated balanced averages for positions 1- 4 will be displayed. In other columns, there are commands to display measured values 1 - 5 for all four positions. #TEST05 Position No. − 1 [%] 2 [%] 3 [%] 4 [%] 5 [%] [%] 1 #VAL1 #VAL1_1 #VAL1_2 #VAL1_3 #VAL1_4 #VAL1_5 2 #VAL2 #VAL2_1 #VAL2_2 #VAL2_3 #VAL2_4 #VAL2_5 3 #VAL3 #VAL3_1 #VAL3_2 #VAL3_3 #VAL3_4 #VAL3_5 4 #VAL4 #VAL4_1 #VAL4_2 #VAL4_3 #VAL4_4 #VAL4_5 #ENDTEST 6.5 Uncertainties The program can, within the protocol, display values of calculated measurement uncertainties. 6.5.1 Standard Uncertainty of Type A Its value is displayed by predefined UA command. It is calculated from the formula: n 1 2 u A ( ) = ( i − ) n.(n −1) i=1 6.5.2 Standard Uncertainty of Type B Its value is displayed by predefined UB command. It is calculated from the formula: zmax uB = zmax is the maximum specified error of the utilized standard meter in the given load point. It is calculated by comparing the largest allowed error from the technical specifications of the manufacturer and from the determined systematic mistakes from the last calibration lists of used reference. If, during calibration, no bigger error than the largest allowed has been determined, we will use the technical specifications of the reference for zmax calculation. If this is not the case, we will calculate the zmax value using the values of systematic errors from the calibration list. χ is a constant which specifies the distribution of probability variances. For uniform probability variance distributions the value is: χ = 1,73. 6.5.3 Combined Standard Uncertainty Its value is displayed using the predefined UC command. It is calculated from the formula: u ( ) = u 2 ( ) + u 2 ( ) C A B where: uA ( ) is the A type standard uncertainty, uB () is the B type standard uncertainty, u ( ) C is the resulting combined standard uncertainty. www.appliedp.com ELMASW-UG160-EN 117 ELMA - Control System User‘s Guide 6.5.4 Expanded Uncertainty of Measurement It is displayed using the predefined UR command. It is calculated from the formula: U = k .u U C where: ku is the expansion coefficient, ku and zmax have predefined values: ku = 2, zmax = 0.05 The choice of factor ku, which is usually in the range 2 < ku < 3, is based on coverage probability or level of confidence (denoted as p) required of the interval x – U to x + U (where x is measured value or average of more measured values). In most cases k = 2 is recommended. The value ku=2 determine the probability of finding the real (true) value within the range x ± U as equal to 95% (assuming that random errors are following Gaussian distribution). It is customary to write the measured value as x ± U. Modification of zmax and χ values is possible only in service mode in the „Parameters“ window of the „Workbench“ bookmark. The value of the expansion coefficient can be modified in the „Parameters“ window of the „Evaluation“ bookmark in the „Uncertainties“ field. 6.6 FastReport reporting system FastReport is large software component with many functionalities. FastReport system needs for its function SQL database, where measurement configuration and test results are stored. For ELMA such database is EDEX (usually located in C:\ELMA\EDEX\edex.gdb file). More information about EDEX subsystem can be found in chapter 12 EDEX System Overview on page 149. ELMA software is preinstalled with set of default templates which should meet the needs of most users. If someone wants to create custom template or edit existing one he must be familiar with SQL language (except for very simple changes). For power users who wants to write their own templates there is specialized manual which can be downloaded from http://www.appliedp.com/download/software/edex/FR5UserManual- en.pdf. The main advantages of FastReport system in comparison with old system based on MS Word are as follows: • greater flexibility – no need to define separate templates for stations with different number of positions or different measurements with different number of tests • ability to filter tests displayed in table (user can for example remove rows corresponding to stop tests or dosage tests as an example) • ability to highlight results which are outside of limits with bold font or red color • No need to remember names of template parameters. All supported parameters are displayed in toolbar window grouped by database tables in which they are stored. • Greater scale of output formats. ELMA currently supports following output formats: o MS Word 2003 (*.doc), MS Word 2007 (*.docx), o MS Excel 2003 (*.xls), MS Excel (*.xlsx), o MS PowerPoint 2007 (*.pptx), Open Document Spreadsheet (*.ods), o Open Document Text (*.odt), HTML4 (*.html), o HTML5 (*.html), Scalable Vector Graphics (*.svg), o Portable Document Format (*.pdf), Rich Text Format (*.rtf), o bitmap image (*.bmp), JPEG image (*.jpeg), o TIFF image (*.tiff), Gif image (*.gif), o simple text file (*.txt), CSV file (*.csv) • Ability to fill selected template “online” which means that in autorun mode template will be automatically filled after finishing some test in measurement. This mode of function shouldn’t slow autorun mode because template filling happens in background (except for very large measurements containing more than 1000 tests combined with tests whose duration is less than 1 minute). • Ability to export sample values measured so far while the test is running. Sample values can be exported for example to MS Excel and user can analyze them while the test continues to run. 118 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide • ability to add charts to output protocols • if dynamic content is needed, templates can be customized by C++ or Pascal scripts • ability to add data from customer specific database 6.6.1 FastReport configuration FastReport configuration page is located in main menu item Configuration → Parameters → Protocol → FastReport. Configuration parameters are described on page 52 of this manual. 6.6.2 Starting FastReport There are four ways how a user can invoke functionality related to FastReport: 1. Clicking on main menu item System → Generate quick protocol. 2. Running archiving process by clicking on button Protocol in Results window. 3. Opening FastReport template designer by clicking on main menu item System → Protocol → Open FastReport designer. 4. Enabling online protocol creation. More information can be found on page 54 of this manual. Cases 1 and 2 are essentially the same as generating MS Word protocol by using old system for protocol creation. The only difference is that in window Protocol user must choose FastReport protocol template. FastReport template is identified by file extension “fr3”. 6.6.3 Editing templates FastReport reporting system is based on templates. This is basically the same as with old system which was based on MS Word templates. But there are also some differences: • FastReport uses only one type of template. Compared with old system which used command template from which final protocol template was generated (refer to diagram on page 106). • FastReport templates are created and edited in its own visual designer which can be run from ELMA. • Less need to memorize names of template commands. All supported commands are listed in toolbar window grouped by database table to which it belongs. Complete list of supported commands with detailed description of each one is contained in chapter 12.4.1 on page 1508. • FastReport templates are more abstract than MS Word protocol templates, which means that in many cases one template can be used for broad range of measurements on different stations with different number of positions. If the table is too wide to fit page FastReport automatically breaks it into more parts each printed on separate page. The same rule applies in case if the table contains many rows (corresponding to tests in measurement). www.appliedp.com ELMASW-UG160-EN 119 ELMA - Control System User‘s Guide FastReport template designer can be started by clicking on main menu item System → Protocol → Open FastReport designer. If the active measurement has assigned FastReport template it will be automatically opened. This is how template designer looks like: 1 2 6 3 7 4 5 The workspace is divided into following parts: 1 – menu bar 2 – toolbars 3 – object toolbar 4 – “Object inspector” pane 5 – “Report tree” pane 6 – report design workspace 7 – “Data tree” pane – elements can be dragged from this pane onto a report page For detailed description of designer please refer to FastReport manual which can be downloaded from http://www.appliedp.com/download/software/edex/FR5UserManual-en.pdf. To fill template with data from database please use shortcut Ctrl + P (preview) or use menu item File → Preview. 6.6.4 Preinstalled templates ELMA is preinstalled with set of templates stored in directory C:\ELMA\TEMPLATE. These are some of them: Template name Purpose BasicReport_Portrait.fr3 General purpose template printed on portrait paper format. BasicReport_Landscape.fr3 General purpose template printed on landscape paper format. For these 2 templates it is possible to define the final look of the protocol using a variables. If you want to configure the variables, please use main menu item Report → Variables. It opens the Edit Variables window. 120 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide To select the particular variable you must click on it in the left part of the Edit Variables window. Then in bottom of the window called Expression you can see the actual value of this variable. Here you can change it to required value. After editing of all variables to required values, it is necessary to store changes using the green pipe (see red circle in the picture). Description of all predefined variables and their possible values: BlocksHighlight ... when enabled (value 1) then some types of tests will have another background color - default is 0 DosageTestDetails ... when enabled (value 1) then dosage tests will have more lines also with additional subresults - default is 0 MeterErrorTestPrecision ... defines precision (number of decimals) for meter error tests ... default is 2 CounterStatesPrecision ... defines precision (number of decimals) for printing final states of counters ... default is 0 ExecutedTestsOnly ... when enabled (value 1) then only executed tests will be present in the protocol ... default is 0 SamplesVisible ... when enabled (value 1) then for all meter error (and some dosage) tests will be printed (in separate lines) also measured samples ... default is 0 PowerInfoVisible ... when enabled (value 1) then also columns 'POWER' and 'UNIT' are visible in the protocol ... default is 0 UserTextTestsSuffix ... user defined text, which has to be added at the end of test name of input data tests ... default is "" (empty quotes/empty string) UserTextTestsSeparation ... when enabled (value 1) then input data tests are printed on separate page than results tests ... default is 0 LongTextWrap ... when enabled (value 1) then long cell texts are printed on multiple rows without changing the font size ... default is 0 SinglePositionPerPage ... when enabled (value 1) then only one position per page is printed ... default is 0 TestNumbersVisible ... when enabled (value 1) then also column '#'(means sequence number) is visible in the protocol ... default is 0 TestNumbersOriginal ... when enabled (value 1) then order number instead of sequence number is visible in '#' column ... default is 0 DosageTestDetailsUnits ... defines units for dosage test details dependant on energy type(rows Initial and Final) ... 0-Wh/varh, 1-kWh/kvarh, 2-MWh/Mvarh, 3-GWh/Gvarh ... default is 1 www.appliedp.com ELMASW-UG160-EN 121 ELMA - Control System User‘s Guide Example: Here is an example how setting of variable PowerInfoVisible changes the final look of the protocol. Default value for this variable is 0 and protocol looks following: Now we set the variable PowerInfoVisible to value 1, then new columns will be visible in the protocol: 122 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide Template name Purpose BasicReport_Dosage.fr3 Template customized for measurements containing dosage tests with power error measurements. Results for dosage tests are printed in separate table with additional information (dial state before the test, dial state after the test, dial difference during the test, dosage error, power measurement error – related to LED blinking, differential error which is difference between two of previous types of errors). BasicReport_Dosage_Landscape.fr3 The same as above but printed on landscape paper format. LiveTestMonitoring.fr3 Template specialized for exporting sample values while the test is running. It can be used for long-time measurements containing tests with large number of samples. Sample values from first position are exported to chart. This is how sample values exported by using LiveTestMonitoring.fr3 template can look in MS Excel: www.appliedp.com ELMASW-UG160-EN 123 ELMA - Control System User‘s Guide 7. System of User Permissions Certain program tasks can be carried out only whit required user permissions. The system can register several predefined users, while each of them has its own password and certain user permissions. The program divides the users according to their user permissions into three categories: 1. OPERATOR - he can operate the program, possibly also set its parameters 2. TESTER - he can do all what the previous category users, plus he can print protocols and archive results 3. TECHNICIAN - he can do all what the previous category users, plus he can switch the program into service mode, and he can also create, modify and delete any items in the program databases After the program is started, one of defined user can be logged automatically (given in elma.ini file) or login window may appear to prompt the operator to log in. If you need to switch users, you can do so from the program menu, by clicking System / Change user. After the correct user name and password are entered, the current program user will be logged off. Name of the current user is always displayed in the main window, in the second part of the status bar from the left. If you want to log off the current user and log on the basic user, you can do so from the program menu by clicking System / Log off current user. Last logged user can be saved / reused at start-up (saveActiveUser parameter) 124 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 8. Data Exchange with Meters Data exchange with meters is mostly performed via optical interface of meter. Data exchange is accessible only for meters defined as static (electronic). System ELMA is equipped with optical communication heads. Data exchange task can be divided into two groups: • Data Readout (reading meter serial number, energy state, …) • Meter Parameterization - sending command(s) to meters to set their parameters or perform some action (service mode enter, registers deletion, etc.) 8.1 Data Readout modes 1. Readout via Local Evaluation Unit (OPS) and its Optical Communication Head OPTH 1000 a. data exchange is in one time realized only with one meter, when finishes, data exchange continues on the next meter b. OPS is during data exchange switched to COPY mode. In this mode OPS works as gateway between PC and meter optical interface c. ELMA software supports FLAG (IEC 62056-21) protocol mode C for meter register readout or user defined commands for reading particular register d. In the test details it is referred as Direct Data Readout 2. Parallel Readout via EDEX (ELMA Data Exchange System) and Optical Communication Head OPTH 2000 a. data exchange with meters is performed via external program which communicate simultaneously with all tested meters via USB optical communication heads b. data between ELMA software and external data exchange program are exchanged via EDEX system database accessible by edex.dll and its functions c. ELMA software is supplied with program Readout_FLAG.exe which supports FLAG (IEC 62056-21) protocol mode C for meter register readout d. EDEX system enables to use user data exchange software to perform readout if required e. In the test details it is referred as ‘Direct Data Readout’ with checked ‘Use simultaneous readout if supported’ and ‘Use external program’ checkboxes 8.2 Meter Parameterization Modes 1. Parameterization via OPS and its Optical Communication Head OPTH 1000 a. data exchange is in one time realized only with one meter, when finishes, data exchange continues on the next meter b. Local Evaluation Unit (OPS) is during data exchange switched to COPY mode. In this mode OPS works as gateway between PC and meter optical interface c. ELMA software supports following possibilities for performing parameterization: i. FLAG (IEC 62056-21) protocol mode C with predefined commands (telegrams) - in the test details it is referred as ‘Direct Parameterization’. Data exchange with meter finishes when all commands are send. ii. FLAG (IEC 62056-21) protocol mode C with user definable commands (telegrams) - in the test details it is referred as ‘Advanced Direct Parameterization’. Data exchange with meter finishes when all commands are send. iii. Parameterization with external program - enables to run external program which performs data exchange with meter - input and output files are generated for data exchange between ELMA and external program. Data exchange with meter finishes when external program is closed. In the test details it is referred as ‘External Command Line Program Parameterization’. www.appliedp.com ELMASW-UG160-EN 125 ELMA - Control System User‘s Guide 2. Parallel Parameterization via EDEX (ELMA Data Exchange System) and Optical Communication Head OPTH 2000 a. data exchange with meters is performed via external program which communicate simultaneously with all tested meters via USB optical communication heads b. data between ELMA software and external data exchange program are exchanged via EDEX system database accessible by edex.dll and its functions c. ELMA software is supplied with program Write_FLAG.exe which supports FLAG (IEC 62056-21) protocol mode C for meter parameterization d. EDEX system enables to use user data exchange software to perform data exchange with meters according to user communication protocol requirements e. In the test details it is referred as ‘External Command Line Program Parameterization’ with checked ‘Use simultaneous data exchange if supported’ checkbox. 8.3 Readout via OPS and its OPTH 1000 Meter must be defined as static. It is required to define Meter Register Association which enables to recognize meter registers and assign data to particular register. Readout via OPS support • FLAG (IEC 62056-21) protocol mode C • user defined commands for reading particular register It is required to define data exchange test as displayed on the following screen shot: Use test as block margin • when checked, readout test is treated as block margin - dosage tests enclosed between two readout tests are evaluated as dosage block (refer to chapter “10 Batch Test Block” on page 145 for more details) 126 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide Use simultaneous readout if supported • when checked parallel readout is performed Register – All registers • Empty - readout of all register according to FLAG (IEC 62056-21) protocol mode C • Selected particular register - readout of selected register using command defined in Meter Type Database - Commands - Data Readout - Defined Data Readout (Refer to chapter „Page ‘Data Readout’” on page 90) Test behavior • After running the test system will apply nominal voltage to the meters (if not already applied) • Switches OPS on first enabled position to COPY mode and starts data readout with meter • When meter data readout on this position finishes, continues on the next enabled position until last enabled position • Successful readout is indicated with + mark in green field, failed readout is indicated with - mark in red field • System will try to perform data readout on failed positions another two times 8.4 Parallel Readout via EDEX EDEX system is compatible with older OPTH 2000 (USB) and with recent OPTH 1000 (Ethernet / RS422). Either of optical heads is visible for ELMA software as serial port. Meter must be defined as static. It is required to define Meter Register Association which enables to recognize meter registers and assign data to particular register. Parallel Readout via EDEX supports • FLAG (IEC 62056-21) protocol mode C - as standard supplied by Readout_FLAG.exe • Any communication protocol - depends on implementation of data exchange into data exchange program Test type • data exchange test Parameters • Direct Data Readout Register combo box • Empty Use test as block margin When checked, readout test is treated as block margin - dosage tests enclosed between two readout tests are evaluated as dosage block (refer to chapter “10 Batch Test Block” on page 145 for more details). Use external program • Must be checked to perform data readout via external software Use simultaneous readout if supported • must be checked for parallel readout It is required to define external software which should be executed during test.

All measured and collected data are stored into EDEX database by ELMA SW and are accessible to external software via interface edex.dll. • When external software closes ELMA software takes control and uses data stored by external software to EDEX database for evaluation of the test 8.5 Parameterization via OPS and its OPTH 1000 Meter must be defined as static. Parameterization via OPS supports: • FLAG (IEC 62056-21) protocol mode C with predefined commands (telegrams) - test details in the section ‘Parameters’ set ‘Direct Parameterization’ - more in chapter “8.5.1 Direct Parameterization - sequential” (p. 129) • FLAG (IEC 62056-21) protocol mode C with user definable commands (telegrams) - test details in the section ‘Parameters’ set ‘Advanced Direct Parameterization’ - more in chapter 8.5.2 Advanced Direct Parameterization - sequential (p. 132) • Parameterization with external program - enables to run external program which performs data exchange with meter - input and output files are generated for data exchange between ELMA SW and external program. Data exchange with meter finishes when external program is closed. Test details in the section ‘Parameters’ set ‘External Command Line Program Parameterization’ - more in chapter 8.5.3 External Command Line Program Parameterization - sequential (p. 133) 128 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 8.5.1 Direct Parameterization - sequential This type of parameterization test performs parameterization directly from program ELMA without use of an external parameterization program. Commands are already predefined in the program ELMA. Commands and their names correspond to commands defined in the FLAG (IEC 62056-21) standard. Direct parameterization has several advantages when compared with external parameterization programs - it is universal, independent of other programs, faster and more transparent. When defining this type of parameterization test it is necessary to select commands to be performed during communication with the meter. You can select the commands by dragging them from the list of supported commands (the upper window) using the mouse to the list of selected commands (lower window). Any of the commands listed in the list of selected commands can be deleted by clicking the ‘Delete’ button, or you can change their order using the arrow keys. The parameters of commands which use parameters, can be set after selecting the given command in the list of selected commands - if set, the parameters are displayed to the right of the command.

Typical usage of this file is sending error message(s) to ELMA software, which can then repeat call of external software (USERprogram). This is useful if for example electricity meter is not able communicate because of bad position of optical head. In this case the ELMA software can indicate to operator an error received from external program (USERprogram) and after finishing all other positions ELMA software can repeat the call of external program on that position (with adjusted position of optical head). Before ELMA software calls external program existing Output file is deleted and another one has to be created by external software. Structure of this file is standard Windows ini file with sections and parameters (each on separate line). File can contain more (for ELMA unnecessary) lines (information). ELMA software will use these parameters for test/position evaluation.

Parallel Parameterization via EDEX supports: Parameterization with external program - enables to run external program which performs data exchange with all enabled meters. Data between external software and ELMA software are shared via EDEX database. Test details in the section ‘Parameters’ set ‘External Command Line Program Parameterization’. This type of parameterization is designed for data exchange with meters via external program. This program can be user parameterization or calibration software. When defining this type of parameterization test it is necessary to select commands to be performed during communication with the meter. You can select the commands by dragging it from the list of supported commands (the upper window) using the mouse to the list of selected commands (lower window). Any of the commands listed in the list of selected commands can be deleted by clicking the ‘Delete’ button, or you can change their order using the arrow keys. Test type • data exchange test Parameters • External Command Line Program Parameterization Use simultaneous readout if supported • Must be checked LP Definition • optionally it is possible to activate load point generation - apply voltage and current to meter and also run measurement of meter error • when check box is ‘enabled’ then load point definition is accessible via button ‘LP definition’ • when in load point definition number of Samples is equal to zero - only defined load point will be applied then data exchange will start • when in load point definition number of Samples is non-zero value - defined load point will be applied and subsequently meter error measurement will start. When system measures defined amount of meter errors (samples) for each enabled position then data exchange will start. Selected command must have appropriate definition of external program details in the database of meter types as follows: www.appliedp.com ELMASW-UG160-EN 139 ELMA - Control System User‘s Guide Definition of executable with its parameters: Optional definition of commands: 140 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide Parameterization program file • enables to enter external program path and all required switches or parameters • parameter [INPUT] will be substituted with path of Input file during staring external software • parameter [OUTPUT] will be substituted with path of Output file during staring external software Test behavior • After running the test system will apply nominal voltage to the meters (if not already applied) or apply defined load point and perform measurement of meter error • Run external program and waits until external program is closed • When external program starts it can read all required information from EDEX database, then can execute data exchange with meter • When external program finish meter data exchange (parameterization/calibration) it should write results / status of data exchange for each position into EDEX database and should be closed • When external program closes ELMA takes control - read status of data exchange from EDEX database and use this information for meter evaluation www.appliedp.com ELMASW-UG160-EN 141 ELMA - Control System User‘s Guide 9. Running Tests When any test is started this window always appears: When any test is being stopped this window always appears: Main purpose of these windows is to secure the main window during starting and stopping of tests when accidental mouse clicking around might occur. Button Terminate Test allows to immediately termination of test generation as a prevention of accidental test triggering. Alternatively also F9 button can be used when this window appears to terminate starting test. 9.1 Auto-run Test Mode Auto-run Test mode enables automatic execution of tests in measurement without operator intervention. When auto-run test mode is activated after finishing test, program will automatically continue with executing next test in measurement until it will reach end of measurement. Automatic tests execution can be interrupted anytime by operator. In case of some problem (error) in system, program will immediately interrupt the automatic test execution and prompt operator for intervention. Activation/deactivation of auto-run test mode is available through menu “System -> Auto-run mode” or from button’s Test popup menu item 1“Auto-run test mode”. State of auto-run test mode is signalized in caption of button Test. Signs “>>” in caption means that system is activated. No “>” sign means that system is deactivated. Selected test can be run by following ways: A. button Test B. selecting from menu “System -> “Test” C. double click test name D. pressing ENTER key E. pressing key F9 When auto-run test mode is deactivated all types of test running are equal. When auto-run test mode is activated behavior of program after running the test depends on the kind of running: • C and D: only single test (selected) will be executed • A, B and E: cause activation of automatic test execution, i.e. selected test will run and after finishing it, another test will start automatically and so on, until the end of measurement or until an error or interruption from operator. Each test processing can be interrupted if it is required: a. button Test click b. selecting from menu “System -> “Test” c. pressing ENTER key d. pressing key F9 After using any operation from above cause interruption of actual test and abortion of auto-run test mode. Except of interrupting manual test with option c. It will interrupt the actual manual test but system will continue with automatic execution on next test. 142 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide Special shortcut for switching ON or OFF the automatic test execution is Ctrl + F9. This will cause that system will wait until actual test will normally finish and after that stop - interrupt automatic test execution. State of waiting until actual test finish is signalized by sign “>” in caption of “Test” button. On the other hand if the AutoRun was not enabled and some test is running, CTRL + F9 will enable AutoRun even during running this test. This feature is also available from button’s Test popup menu items 3 “Stop run after this test” and 4 “Switch to auto-run mode”. Caution: Auto-run Test Mode works correctly only for Testing. In Adjustment mode the ELMA SW does not perform tests sequentially, because they are triggered and ceased by user! 9.2 Auto-run Infinity Test Mode Auto-run Infinity Test mode enables automatic execution of tests in measurement without operator intervention. Program automatically runs all tests from measurement one by one until it will reach the end of measurement. Automatic tests execution can be interrupted anytime by an operator. The difference between Auto-run mode and Auto-run Infinity mode is that in case of some problem (error), the system program will continue the execution of automatic test without prompting operator for intervention. When the Auto-run infinity mode reaches the end of measurement, the error window will be shown in case of some errors during tests. All tests which contain some error have the icon signed with exclamation mark inside the icon of main window. We distinguish 2 types of error during test: • error of optical sensor in some position -> in this case the exact position number is shown at the end of measurement in error window. In case of optical sensor error a special time is defined, during which operator has chance to correct the optical sensor of error position. This time is defined (in seconds) as “measTimeout” parameter in elma.ini file in [Param.Measurement] section and can be defined by the operator editing the elma.ini file before start-up of ELMA program. If the operator corrects the error positions until the specified time, the test is considered as successful and it is not contained in error window at the end of measurement. • error in output generation -> in this case the “-” sign is shown at the end of measurement in error window. Activation/deactivation of auto-run infinity test mode is available through menu “System -> Auto-run mode infinity” or from button’s Test popup menu item 2 “Auto-run mode infinity”. State of auto-run infinity test mode is signalized in caption of button Test. Signs “>>>” in caption means that system is activated. No “>” sign means that system is deactivated. Selected test can be run by following ways: A. button Test click B. selecting from menu “System -> “Test” C. double click test name D. pressing ENTER key E. pressing key F9 When auto-run infinity test mode is deactivated all types of test running are equal regardless the way of triggering them. Thus, all five ways of starting the test are the same. www.appliedp.com ELMASW-UG160-EN 143 ELMA - Control System User‘s Guide When auto-run infinity test mode is activated behavior of program after running the test depends on the kind of running: • Running a test using type C and D will cause only single test (selected) execution, therefore no automatic continuing of other tests will take place • Running a test using type A, B and E will cause that selected test will run and after it is finished, another test will start automatically (also in case of an error). This process continues until end of measurement is reached (i.e. all remaining tests will accomplish), or interruption from operator has happened. Each test processing can be interrupted if it is required: a. button Test click b. selecting from menu “System -> “Test” c. pressing ENTER key d. pressing key F9 After using any operation from above cause interruption of recent test and abortion of auto-run infinity test mode. Except of interrupting manual test with option c. It will interrupt the actual manual test but system will continue with automatic execution on next test. Special shortcut for interrupting of automatic test execution is Ctrl-F9. This will cause that system will wait until actual test will normally finish and after that stop - interrupt automatic test execution. Main indication of deactivated system is signalized by sign “>” in caption of “Test” button. Caution: Auto-run Infinity Test Mode works correctly only for Testing. In Adjustment mode the ELMA SW does not perform tests sequentially, because they are triggered and ceased by user! 144 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 10. Batch Test Block During testing of static meters with optical communication it is advantageous to merge batch tests (dial tests, maximum test) to one batch block bounded by reading registers. Register association must be defined for registers used by tests generating the batch block. 10.1 Principle Batch block is bounded by two tests - reading of registers initial and final. Both of them must have checked parameter “Use test as block margin”. Between this two tests are placed batch tests - dial tests and maximum tests. No other types of test can be placed into block except tests which generate zero power - data input from terminal or parameterization tests. Batch test block starts with running of initial registers reading (Test “Read Registers - Initial” in followed pictures). After execution of this test it is possible consistent launching of batch tests. When concurrent running of batch tests is enabled (“Parameters->Measurement->Enable concurrent batch tests”) test with matching load points are executed concurrently. Each executed test is signed by light blue color which signalized that test was executed but not evaluated yet. After all batch tests are done it is possible to run final registers reading (Test “Read Registers - Final”). When final register reading is finalized all executed batch test are to be evaluated. To guarantee correct behavior during concurrent test running it is important to meet followed order of tests: Dial tests must be in the beginning of block and they can be followed by maximum tests. Reason for this is very simple - when in automatic test run mode system automatically starts dial test with this test can run at least one maximum test (if defined). The precision of energy dose is controlled by Reference Standard. But when you place maximum test prior to dial test, system will automatically start maximum test and concurrently with maximum test will proceed dial test, but during tests Reference Standard doesn’t control energy dose only specified time for maximum test is guaranteed. To optimize process of concurrent batch test running program automatically adjust batches and times of tests. 10.2 Practical example of batch test block Picture above shows example of batch tests prepared for execution. 4th column displays energy doses and times required for test running. Tests with optimized energy doses and times have initial value displayed in brackets. In this example were optimized tests: www.appliedp.com ELMASW-UG160-EN 145 ELMA - Control System User‘s Guide • “Dial Test total” - this test will run concurrently will all tests in block except “Dial Test supply total”. Program optimized energy dose for this test to match to maximal energy dose from possible concurrent tests. Note: For dial test in which is tested register total is energy dose information irrelevant because real energy dose is sum of energy doses from all concurrent tests. • “Maximal Power” and “Maximal Current” - Defined times of duration for both test is 1 minute. System recognized that these tests can concurrently run with test “Dial Test tariff 4” and therefore optimized time of duration of these tests (time 10.03 minute is required for energy dose 2.5kWh). Followed picture shows two concurrently running tests: Test “Dial Test total” is concurrently running with test “Dial Test tariff 1”. Applied power increments both registers “Energy total” and “Energy tar. 1”. Picture above show concurrent running of tests “Dial Test tariff 2” and “Dial Test total”. Test “Dial Test total” is running second time. Test “Dial Test tariff 1” is signed by light blue that means that test is already executed but not evaluated. It is not possible to run again already executed test. Followed picture shows running test “Dial Test tariff 4”. Concurrently with this test are running another 4 tests. 146 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 11. Testing meters with different constants and ratios ELMA software enable to measure in one batch meters with different constant, different ratio or different tolerance (class) while nominal and maximal ratings of voltage and current must the same for all meters within tested batch. This measurement creates requirement to enter these additional information for each meter into the system. ELMA software provides this facility 4 test types: • EM Constant for LED/Disc • EM Constant for SO • EM Ratio • EM Tolerance Parameters of the test enable to set data input type: • Data input from hand-held terminal • Data input from PC (keyboard in string format) Example of test detail: When there is no test for entering meter constants or ratios or these tests are not done, program will behave as standard and constant and ratio will be taken from meter type definition. 11.1.1 Meter Constant Entering Test behaves as standard user text input. When started, operator is asked to enter data via hand-held terminal or directly via PC keyboard. Constants must be entered in unit imp/kWh, resp. rounds/kWh. For indirect meters are entered constants treated as primary. 11.1.2 Meter Ratio Entering Test behaves as standard user text input. When started, operator is asked to enter data via hand-held terminal or directly via PC keyboard. Entered ratio must be multiplication of voltage and current ratio. 11.1.3 Meter Tolerance Entering Test behaves as standard user text input. When started, operator is asked to enter data via hand-held terminal or directly via PC keyboard. 11.1.4 General notes Selected Meter Type must have the same setting of constants and ratio as at least one of tested meters. www.appliedp.com ELMASW-UG160-EN 147 ELMA - Control System User‘s Guide This feature is available by combination of setting of OPS predivider and nominal impulses. When measuring dynamic meters it is not possible to use predivider therefore in this case range of measured constants can be 1:10. While measurement of static meters there are no restrictions. For Register test and Maximum demand test system evaluates entered ratios for each measured position. In real situation this means that each meter with different ratio registered different batch of primary energy or power. 148 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 12.

Priority of them is as follows (from highest to lowest): customized (per test) meter tolerance defined in measurement database, customized (per position) meter tolerance defined by “EM Tolerance” test, database of tolerances, database of electricity meters (see class & class reactive fields) 168 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 13. DLMS 13.1 Main Features From version 16.00 ELMA SW supports readout and parameterization of DLMS meters. This was possible also in previous versions using parallel readout via EDEX database (described in previous chapter). For this purpose user has to provide external program written specifically for particular type of meter. To unify communication (readout / parameterization) with various types of DLMS meters from various manufacturers Applied Precision created universal external program for DLMS meters. Program was tested with meters from following six manufacturers: Landis&Gyr, ADD Grup, Iskra, Mikroelektronika, Meter&Control a Sanxing. It is possible that it will function also with other types of DLMS meters if properly configured. However, this cannot be guaranteed because of differences in implementation of DLMS protocols between various manufacturers. Communication program is named dlms.exe and commonly it is stored in C:\ELMA\EDEX directory. ELMA software was also enhanced to support configuration of parameters related to DLMS protocol. 13.2 Description of changes in ELMA SW related to testing of DLMS meters 13.2.1 Database of meters New settings can be accessed from „Data Exchange“ page of electricity meter types database. Electricity meter register association Example of register association dialog in next screenshot: www.appliedp.com ELMASW-UG160-EN 169 ELMA - Control System User‘s Guide DLMS protocol is more versatile than IEC but at the cost of higher complexity. User, for testing of DLMS meters, needs to know more parameters that are required to be entered into ELMA software or communication utility dlms.exe. It is not possible* to do universal readout, where all registers were read from meter. Another specific issue with DLMS meters is that register set can be different between various meter manufacturers. For practical purposes, it is good to read only user specified subset of registers. For particular data exchange test, it is possible to reduce this set even further and read only three – four required registers. The meaning of columns is as follows: Object address – Unique identification number of meter register. The syntax uses 6 fields. IEC address is a subset of DLMS address. Special attention is needed while editing this property. Incorrect value can result into reading different register from meter. Type of register – Type is used to reference particular register in test properties. The value of this field can be changed by dragging it from list in right part of window. Multiplication constant – optional real number to scale numeric value read from meter. Typically this is used for converting unit for example from Wh to kWh. Object type – type of DLMS register object type. It is one of predefined values Data, Register, Extended Register, Clock. Special attention is needed while configuring this property. Incorrect value can result into communication error. User can obtain required configuration data from meter manufacturer or for commonly used registers to use auto detection (see below). Readout name – optional string under which the value of particular register will be identified in test results. Empty string means object address will be used. List on the right part contains currently supported meter register types. Filter is available for this list using edit box above. The list supports drag-and-drop. Under the table, there are buttons with following functions: - Change order of registers supported by the meter type Delete – delete definition of selected register type Delete all – delete definitions of all register types Fill default addresses – fill default object addresses for all register types Fill default registers – removes current definitions of register types and adds all default register types that are needed to verify basic functionality of meter (for example 1.6.x, 1.8.x, 2.6.x, 2.8.x, 3.6.x, 3.8.x etc.) *Note: It is possible to read all, but the register set is so huge that it would take a few minutes to read all of them. 170 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide Communication settings This window was named „Port settings“ in previous versions of ELMA software. Some of the parameters are related to older IEC 62056-21 protocol. This is because some DLMS meters require to begin communication using IEC protocol. After the communication channel is initialized, communication proceeds using DLMS protocol. Some of these parameters can be later applied also to IEC communication utilities readout_flag and write_flag. Currently they are configured using text files readout_flag.ini and write_flag.ini. Baudrate, Data bits, Parity, Stop bits – basic communication parameters Protocol – IEC (default) or DLMS Communication timeout (ms) – maximum time to wait for answer from meter. If the meter does not respond after this time, communication fails. During initialization of communication if IEC protocol is used; another timeout is used, defined later in IEC settings section. Max.retry count – Maximum number of communication attempts. If there is a communication problem, dlms.exe tries to communicate with meter again. Reset power after communication error – if communication error happens and this parameter is checked, dlms.exe waits to finish communication with all enabled positions. After that, it sends signal to ELMA software to reset meter power. The power is not reset after last communication attempt fail if we know that resulting test status will be bad. The goal is to resolve rare communication errors by reinitializing meter firmware. www.appliedp.com ELMASW-UG160-EN 171 ELMA - Control System User‘s Guide Power off duration (ms) – duration of power outage when communication error happens. This parameter applies only if checkbox „Reset power after communication error“ is checked. During this time, voltage on input terminals of meters will be zero. Length of this period should be adjusted for particular type of meter. Initialization time (ms) – Time to wait after power outage so the meter has time to initialize. This parameter applies only in case when communication error happens and checkbox „Reset power after communication error“ is checked. This time is counted after the voltage on input terminal of meter is turned on and stabilized (which typically takes 2 – 3 seconds). Length of this period should be adjusted for particular meter type. Section IEC settings contains settings for IEC part of DLMS protocol. IEC protocol is used only on the beginning of communication (first few packets). After that, communication switches to DLMS protocol. Some meters (e.g. Landis&Gyr) don’t use IEC protocol at all. Ident packet timeout (ms) – maximum time to wait for first packet from meter Accept high baudrate (read) – True if communication should proceed on higher baudrate than 300 baud for read operation. Value of this parameter can be changed for particular position on Test Devices tab on main form. Accept high baudrate (write) – True if communication should proceed on higher baudrate than 300 baud for write operation. Value of this parameter can be changed for particular position on Test Devices tab on main form. Delay before high speed sent – time to wait after receiving identification packet and before sending request to switch to higher baudrate. Delay after high speed sent – time to wait after switching to higher baudrate and before continue with readout or parameterization Packet begins with STX and finishes with ETX character – Not implemented yet. Later it may be used by utilities readout_flag.exe and write_flag.exe. Send logout (B0) sequence – Whether to send sequence SOH B0 ETX BCC after communication. Not implemented yet. Later it may be used by utilities readout_flag.exe, write_flag.exe or dlms.exe. 172 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide Electricity Meter DLMS settings This window contains following four tabs named Security, Communication settings, Readout and Parameterization. Security tab This tab contains list of DLMS profiles for particular meter type. These are the parameters needed to successfully login to meter. Meter manufacturer can provide them. Profile name – identification string for profile. It is used to refer a profile on other tabs. Any unique string can be used, it is not stored in meter. Authentication type – drop-down menu with three options: None, Low and High. Default option is Low. High option includes encryption of communication and currently it is not supported. Client address – address under which PC software is identified to the meter. Must be paired with configuration stored internally in meter. Client address specifies the access privileges to particular registers. Meter firmware can implement more communication interfaces with different client address. Each communication interface can have different privileges. E.g. one communication interface allows only data readout, other communication interface allows changing some data stored in meter. The communication interface reserved for meter manufacturer has full right access, where also the possibility of firmware update is allowed. Physical server address – physical address of communication unit in meter. Logical server address – logical address of communication unit in meter. Server address size – size of server address in bytes. Password – password. Communication settings tab This tab contains settings specific to particular manufacturer. Settings on this tab can be shared between various meter types (except the value Meter type selected in drop down menu). Meter type (drop down menu) – select between various predefined profiles. Parameters of selected profile are displayed below in group box Meter type properties. Meter type (edit box) – name of profile. This can be any unique string used for identification purpose. Manufacturer – meter manufacturer. This can be any string used for description purpose. www.appliedp.com ELMASW-UG160-EN 173 ELMA - Control System User‘s Guide Start protocol – Protocol used for initiating communication (IEC or DLMS). This setting can be same for various meter types from the same manufacturer (obtained from meter manufacturer). Changing this parameter here will change it for all meter types that refer to this profile. Readout tab Contains settings needed for meter readout. External data readout program – path to external program used for meter readout. Default value is C:\ELMA\DLMS\dlms.exe. This path can include command line parameters. Profile – name of profile from Security tab, which will be applied during meter readout. Full command line parameters – read-only text box containing full path to external program with all command line parameters. User can edit some of them on this tab and some of them will be added automatically by ELMA software (for example path to EDEX database). Parameterization tab It contains definitions of parameterization commands. Table on the left contains list of all supported parameterization commands. Used parameterization commands are grouped in the top part and are distinguished by red arrows next to them. They can be referenced in properties of data exchange test. For quick access of required command filter edit box is available above the list. Right part contains definition of selected parameterization command: Parameterization program file – path to parameterization program. Default value is C:\ELMA\DLMS\dlms.exe. Path to external program can include command line parameters. Profile – name of profile from Security tab, which will be applied during meter parameterization Command – optional hexadecimal command that will be sent to meter 174 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide Full command line parameters – read-only text box containing full path to external program with all command line parameters. User can edit some of them on this tab and some of them will be added automatically by ELMA software (for example path to EDEX database). 13.2.2 Measurements database Communication with DLMS meters can be done using data exchange test. Data exchange test subtype can be configured in one of two ways: - Direct Data Readout - External Command Line Program Parameterization Direct Data Readout Test properties window for data exchange test was changed as follows: User can assign more than one register type to particular test (button Edit in group box Register). Editor of register types looks following: www.appliedp.com ELMASW-UG160-EN 175 ELMA - Control System User‘s Guide In the left part there is a list of register types assigned to test being edited. On the right part there is a list of all supported register types. If you leave the list empty, ELMA will interpret this choice as if all registers were chosen. If you want to narrow the list of registers whose values will be read, you can drag them from the right list. This list will be stored to EDEX database so the DLMS utility dlms.exe can use it. Advantage is faster readout, because only values that will be needed for particular data exchange test or batch test block, will be read. After clicking on OK new values will be assigned to test and displayed in test properties window in shortened form (because the list can be large). External Command Line Program Parameterization Test properties window for data exchange test looks following: 176 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide List of parameterization commands is on the right part of window. Above the list of parameterization commands, there is an edit box, which can be used to type filter condition. According to filter condition list of parameterization commands will be narrowed to include only required items. This can be used to quickly locate required command. Another option how to narrow the list of parameterization commands, is to use checkbox Show only commands defined in electricity meter database. List box in right bottom part of window contains list of parameterization commands that will be applied for this particular test. Up and down arrow buttons change the order of parameterization command. One special type of parameterization command is Set Time & Date. If user does not specify command in meter properties (in hexadecimal format - see chapter Parameterization tab on page 174), dlms.exe will build required command automatically according to settings in test properties window: User can set either current date & time or specify another (fixed) value. If checkbox Set Summer is checked it means that meter will interpret time value as summer time. One exception is if option Actual values from PC is chosen and current time according to what operating system Windows reports is not summer time than set value will be interpreted as normal a.k.a. winter time. This happens if user runs the test for example on first of December. This is because a user can run the same test regardless of the current time of year. 13.3 External program for reading / writing DLMS meters This program is named dlms.exe and commonly should be stored in directory C:\ELMA\DLMS. www.appliedp.com ELMASW-UG160-EN 177 ELMA - Control System User‘s Guide It contains all positions, one on each row, along with their status. Program displays properties as communication port, number of bytes written and read and communication retry count. If no communication error happens, retry count will remain zero. In case of communication error, its description will be displayed in last column (and also in test result for this position in ELMA software). If more than one retry count is set in meter properties and communication error happens, after all other enabled positions finish communication, dlms.exe will send signal to ELMA software to reset power: 178 ELMASW-UG160-EN www.appliedp.com ELMA - Control System User‘s Guide 14.
