Axometrics General Production and QC Software

USER’S MANUAL Software Version 4.0

2 1 INTRODUCTION

The Axometrics Production software package is the primary control software for the APM-20 Axometrics Production system. It interfaces seamlessly with hardware control programs such as the AxoScan Engine™. This software manual discusses the general operation of the Axometrics Production software and the steps necessary to perform an measurement. Section 2 discusses the basic steps performed when measuring an LCD panel, Section 3 discusses the details of setting up a measurement recipe, Section 4 discusses the details of setting up a calculation recipe, and Section 5 discusses the operation of the data viewer software.

3 2 BASIC OPERATION

All axometrics production machines are controlled entirely using the Axometrics Production software. Load the Axometrics Production software by double clicking on the icon on the front panel. The Main Menu for the production software is shown below.

There are 8 sub-menus that the user can access by pressing the buttons on the Main Menu, which will be discussed in this section. The On-Line measurement function will be discussed in a later chapter.

Because all Axometrics production systems use this software, it is necessarily highly configurable. The following describes the primary configurations for the production software.

1. Operation Mode: The software can be configured to operate in either Manual Mode (fully operated by a person from the user station) or Automatic Mode (measurements and operations controlled remotely via TCP (such as using a CIM). 2. Sensor Type: The production software can be used for AxoStep systems and AxoScan systems. 3. Fixture Type: The production software can be configured for several different fixture types, such as: a. APM (Axometrics PanelMapper) Fixtures: Standard transmission tilt and rotation turrets b. FA.x (Fixed Angle) Fixtures: Multiple heads with or without rotation motors c. x.x.RF (Reflection –Type) Fixtures:

4 4. Calculation Type: The production software can be configured to perform numerous different measurements by changing the data fitting subroutines. These calculation routines include (but are not limited to): a. AxoScan LCD panel measurements b. AxoStep LCD pixel measurements c. Ellipsometry measurements d. Optical Anisotropy Measurements.

2.1.1 LOG IN/LOG OUT:

The Axometrics Production software can be configured to log user operation by setting up user accounts. If the software is configured to require an operator login, then no operations can be performed unless a user is logged in. Press the User Log In Button, and log on to the system with your User Name and Password. If the Panel Mapper is configured to use an ID card reader, the user can swipe their ID card to Log On.

2.2 Initialize System

Pressing the Initialize System button opens the following window:

5 Initialize Sensors: Press this button to initialize the AxoScan (or AxoStep) Engine. The initialization sequence is configured in the System Settings-Hardware Options (Section Hardware Options). If the AxoScan Engine is running on startup the Initialize AxoScan Button will be green. If an error occurs or the initialization fails, the button will be red. Information about the initialization is shown in the box below the button

Initialize Optical Gauging Press this button to initialize the Panel Alignment System (if installed). The initialization sequence is configured in the System Settings-Panel Alignment Options (Section Error: Reference source not found). If the Panel Alignment System is running on startup the Initialize Initialize Panel Alignment System will be green. If an error occurs or the initialization fails, the button will be red.

2.3 Calibrate System Screen

6 The Calibration System Screen is displayed when the user presses the Calibration button on the Main Menu.

All controls on the Calibration System screen require that AxoScan has successfully initialized and that a user is logged on.

Perform Calibration Test Measurement: Launches the Calibration Program that is specified in the System Settings-Calibration Options (Section Calibration Options) in “measurement only” mode. In this mode, only a test measurement in air, as well as a measurement of the reference standard in the system (e.g. Cal-Vis-1) is performed, but no changes to the system calibration are made. The results of this measurement are shown in the Calibration Results Table. This is used only to verify the current calibration is within spec.

Recalibrate: Launches the Calibration Program that is specified in the System Settings- Calibration Options (Section Calibration Options) in calibration mode. In this mode, a baseline calibration and orientation calibration are performed and a test measurement is performed. The results of this measurement are shown in the Calibration Results Table.

Save Calibration as Default: Pressing this button will save the most recent calibration as the Default AxoScan Calibration.

2.3.1 TWO STEP CALIBRATION

7 In some cases it is desirable to perform the calibration steps separately (usually in cases where Axometrics software does not have direct control of an XY stage). In this case, the Axometrics Production software can be configured to perform the test measurements and calibrations as two separate steps. If the software is configured this way (See Section Calibration Options) the options on the calibration screen will be as follows:

In this configuration, the buttons operate as follows:

Test Air: Launches the Calibration Program that is specified in the System Settings-Calibration Options (Section Calibration Options) in “measurement only” mode. In this mode, a test measurement in air only is performed, and no changes to the system calibration are made. The results of this measurement are shown in the Calibration Results Table. This is used only to verify the current calibration is within spec.

Test Reference: Launches the Calibration Program that is specified in the System Settings- Calibration Options (Section Calibration Options) in “measurement only” mode. In this mode, a test measurement of the reference standard only is performed. No changes to the system calibration are made. The results of this measurement are shown in the Calibration Results Table. This is used only to verify the current calibration is within spec.

Recalibrate Air: Launches the Calibration Program that is specified in the System Settings- Calibration Options (Section Calibration Options) in calibration mode. In this mode, a baseline calibration in air only is performed and a test measurement in air is performed. The results of this measurement are shown in the Calibration Results Table.

Recalibrate Reference: Launches the Calibration Program that is specified in the System Settings-Calibration Options (Section Calibration Options) in calibration mode. In this mode, a orientation e calibration of the reference standard only is performed and a test measurement in of the reference standard is performed. The results of this measurement are shown in the Calibration Results Table.

Cell Gap: The thickness of the LC layer in the LC cell Rubbing Direction: The rubbing direction on the top surface of the LC cell. This quantity physically corresponds to the director orientation of the top layer of the LCD structure. Twist Angle: The amount the LC directors twist between the top and bottom surface of the LC cell. Front Pre-Tilt: The angle that the LC director tilts into the sample at the top surface of the LC cell. Back Pre-Tilt: The angle that the LC director tilts out of the sample at the bottom surface of the LC cell

These values are set using the LCD Properties Control, shown below:

Values can be changed by adjusting the sliders in the control, or manually entering values. The user also has three options for coupling the front and back pre-tilt angles.

Independent: Front and back pre-tilt angles are independent values Coupled: Front pre-tilt and back pre-tilt are the same value. Anti-Coupled: Front pre-tilt is the negative of the back pre-tilt

3.1.2 REFRACTIVE INDICES

Using the Refractive Index Dispersion Control, the user can directly enter the Cauchy terms, or enter the refractive indices at several different wavelengths in the table. If the refractive indices are entered manually, click the Find Cauchy Terms Button to determine the Cauchy Coefficients for the refractive index data. For more information on the Refractive Index Dispersion control, see Section 4.3 in the LCDView Users Manual.

3.1.3 FITTING OPTIONS

Also, on the tab control, the user can set the Fitting Options used in the LCD calculation.

The Fitting Options Tab gives the user two options for setting the number of layers, and thereby determines the simulation accuracy.

40 Adaptive Layer Count: LCDview uses an iterative algorithm to determine the type of LC cell, and adaptively determines the optimum number of layers necessary to accurately represent the inhomogeneous variation of the LC cell.

Manual Layer Count: The user can manually enter the number of layers used for the simulation.

In general, it is recommended that the user use the Adaptive Layer Count option when fitting LC data. However, if unusual results are obtained, the user might want to consider using the manual layer count.

There are also additional options that can be set by the user

Max Iterations is the maximum number of iterations that the optimization algorithm will use to fit the data

Tolerance is a parameter used by the algorithm to determine when to stop the optimization procedure.

Remove blocked data points: If this box is checked the software will remove any data points that are blocked (by support rails for example) from the data fitting calculation and only use unblocked values.

Transmission Threshold (% of Max): This is the threshold that is used to determine when to remove a blocked data point. It is given as a percentage of the Maximum Transmission that is measured in a given data set. Since the transmission for all tilt and rotation angles should be within a few percent of each other, a data point that is less than say 10% of the maximum transmission measurement can be safely rejected since it is most likely either fully or partially blocked..

Include Panel Bending: Check this box to include panel bending in the data optimization. Panel bending information is obtained through additional sensors (such as an autocollimator) that are included on some systems.

3.1.4 COMPENSATION

A section is included for sample compensation

41 Color Filter Rth (nm): On VA-type cells, the color filter can have a significant effect on cell gap measurements. Here the user can enter a compensation factor for the effects of the color filter. Typically the Rth of the isolated color filter is measured off line, and is entered here.

Color Filter Facing Up: Select this when the color filter is facing the PSG

Color Filter Facing Down: Select this when the color filter is facing the PSA

Cell Gap Correction: An option is given for applying a linear correction factor to the cell gap measurement. The correction factor is given as a linear offset of the form

New Cell Gap = A*(Old Cell Gap)+B where the values of A and B are provided by the user.

3.1.5 PARAMETER LIMITS

Measurement Parameter Limits are configured on the Parameter Limits Page.

Parameter Limits can be configured for each of the 5 measured values in the LCD Panel Measurement calculation. Parameter limits are configured as follows:

Max Value: Registers a bad measurement if the parameter exceeds this value Min Value: Registers a bad measurement if the parameter is less than this value

Active: Check this box to enable parameter limit checking on each measurement. Parameter limits are ignored if this box is un-checked

3.1.6 GLOBAL PARAMETER LIMITS

42 The LCD Panel Measurement Calculation also allows the user to set global parameter limits. These are limits that are placed on the variation of the parameters over all measurements performed in the recipe.

Global parameters can be configured in one of 3 ways

Range (Max-Min): Registers an alarm if the Maximum measured parameter – minimum measured parameter (over all measurements performed by the recipe) exceeds the value entered.

St.Dev (σ): Registers an alarm if the standard deviation of the parameter (over all measurements performed by the recipe) exceeds the value entered.

CV%: Registers an alarm if the Critical Value percent (100*St.dev/average) of the parameter (over all measurements performed by the recipe) exceeds the value entered.

3.1.7 LAUNCH LCDVIEW

The user can also launch LCDView to set up the calculation recipe. Refer to the LCDView user’s manual for more information on fitting LCD data using LCDView.

3.2 Measurement Settings

Setting up a measurement recipe requires configuring the three primary measurement variables used production system: x,y Coordinates: The list of positions on the panel that are measured. Tilt, Rotation Angles: The tilt and rotation angles that are measured at each point Wavelengths: The wavelengths used at each measurement

43 When the Load Measurement Recipe Button is pressed on the front panel, the LCD Measurement Recipe Builder window opens, which allows the user to configure the measurement recipe.

The following sections describe the steps necessary to properly set up a measurement recipe

3.3 x,y Coordinates Setup

The first tab on the LCD Measurement Recipe Builder allows the user to setup the x,y Coordinates that will be used for the measurement. (Note: Cell Number is optional)

The x-y coordinates can be expressed in one of two ways

1. Absolute coordinates: The values in the coordinate list are the actual position values of the x-y stage motors.

2. Panel coordinates (only available with Panel Alignment machine vision system): The values in the coordinate list are measured from the lower left alignment mark on the LCD panel being measured, and the x-axis is the line joining the two alignment marks on the panel. The measurement locations illustrated on the x-y coordinates tab shown above are drawn using the last successful panel alignment measurement. The actual motor location are adjusted accordingly each time an alignment measurement is performed. Therefore, even if the panel is repositioned in the panel holder, the same location on the panel is measured.

The relationship between panel coordinates and absolute coordinates is illustrated below.

44 offset y Panel Coordinates

Absolute (Stage) Coordinates offset x The user has three options for setting up these coordinates.

Load From File: The user can load a tab delimited file of x and y coordinates that will be imported into the table.

Enter By Hand: If the user presses the Enter By Hand button, the following window appears, allowing the user to manually enter x,y Coordinates.

Wizard: If the user presses the Wizard button, the Map Setup Wizard window appears, allowing the user to easily configure the x,y coordinates

45 The first step when using the Map Setup Wizard is to move the x,y table to the first measurement position on the panel by using the Jog controls or manually entering the Coordinates and pressing the Move button, or by dragging the cursor in the window. Once the x,y table is in the correct position, press the button. Then press the

button

Once the first position has been set, the text above the button changes to “Step 2” and the text on the button also changes indicating that the user move the x,y table to the opposite corner of the desired measurement area, which will correspond to the second position. Once the x,y table is in the second position, press the button. Then press the

button

Once both positions have been selected, the following control appears, allowing the user to set the number of points in the measurement. In the example shown below, the user has selected an array of 3 points by 3 points (9 total measurement positions) whose corners are defined by the two points previously selected by the user.

46 Once the array of points is defined, they are shown on the screen and the Finish button is shown. Pressing the Finish puts those values in the XY coordinates table on the Measurement Settings Page.

Note: When the user selects Panel Coordinates, the two alignment marks appear in the window, allowing the user an easy reference for navigating the panel. All the controls on the window are also converted to panel coordinates, except the cursor window, which always shows the absolute position of the motor stages.

3.4 Tilt, Rotation Angles

The Tilt and Rotation Angles that are available for configuration is highly dependent on the measurement fixture of the system being used.

3.4.1 APM TURRETS

For systems with both tilt and rotation motors (APM-type) the following controls are available for setting the tilt and rotation angles

47 There are four methods for configuring the tilt and rotation angles for an APM-type turret.

Load From File: Press this button to open a file dialog to load a comma delimited text file that contains the Azimuth and Polar Angles to be measured.

Enter By Hand: Press the Enter By Hand button to open the following dialog box allowing the user to enter the Azimuth and Polar Angles by hand.

Tilt Wizard: When this button is pressed, the following window appears.

This utility allows the user to enter polar angle scans along arbitrary rotation angles. The rotation angles can be entered manually, or the user can enter equally spaced rotation angles.

Rotation Wizard: When this button is pressed, the following dialog appears.

48 The wizard automatically generates azimuth angles spanning 360 degrees, starting at the Initial Rotation Angle.

3.4.2 FAA-TYPE TURRETS

For systems with only a rotation motor and fixed tilt angles (FAA-type) only Azimuth can be configured. Currently only two options are available to configure the Azimuth

Load from File: Press this button to load a list of Azimuth angles from a text file.

49 Enter by Hand: Press this button to manually enter the Azimuth Angles

Note that the Fixed Tilt Angles are displayed for reference purposes.

3.4.3 FAF-TYPE TURRETS

For systems with fixed polar angles and fixed azimuth angles (FAF-type) there is nothing to configure. A table showing the fixed tilt and rotation angles is displayed for reference

3.5 Wavelengths.

The third tab on the LCD Measurement Recipe Builder allows the user to setup the wavelengths that will be used for the measurement.

The polarimeter performs measurements at the wavelengths entered by the user. These wavelengths can be loaded from a file or entered by hand, using the following control.

50 If the user presses the Wizard button, the following control appears, allowing the user to setup the wavelengths automatically.

51 4 PRODUCTION MODE

If the system is configured for Production Line Mode (See Section Production Line) several additional features appear on the front panel.

Online Measurement: This button puts the system into On-Line Mode so that it can receive measurement commands remotely.

Online Recipe: This indicator shows the On-line Recipe that is currently loaded. Glass ID: This indicator shows the Glass ID (if provided) CIM Connected: This indicator is illuminated when a TCP/IP connection is established with a CIM computer

4.1 On-Line Recipies

When the system is configured for Production Line Mode, a second recipe table is displayed on the recipes page.

52 On-Line Recipes are configure in an identical manner to manual recipes. Additionally On-Line recipes can be copied from Manual Recipes (and vice-versa).

Note: Only On-Line Recipes are available to the CIM computer for measurement.

4.2 Production Status

When Production Line Mode is enabled, the status of the Production communications can be monitored on the Status page (See Section System Status).

53 The following a description of the indicators on the Production Status Tab.

Running, Ready and Alarm/Down: This indicates the current state of the system. 1. The Running light is illuminated when the system is actively measuring 2. The Ready light is illuminated when the system is in currently operating properly but not actively measuring 3. The Alarm/Down light is illuminated when there is a problem with the system that prevents it from making a measurement.

Ready to Measure, Safe to Load, Safe to Unload, Measurement Complete and Glass Present indicate the current condition of the machine. These are described below in Section System States.

CIM Connected: This light is illuminated when a connection is established on the production line listening port (typically 50000).

Sensors (PLC) connected: This light is illuminated when a connection has been established with the system sensor monitor (typically a PLC)

AxoScan Status Connected: This light is illuminated when a status connection has been established with all sensor head on the system.

Enable_Status: This light is illuminated when the ENABLE_STATUS command has been issued causing the Production software to send unsolicited messages when any production status change occurs.

Alarm Info: This indicator shows a list of all active alarms and warning.

Production Log: This indicator shows a log of all Production Activities.

54 4.3 System Control

The communication system is configured using two state variables (Mode and OperationMode)

Mode: Refers to the connection status between the client computer (ex. CIM computer) and the APS software and it can be in one of two states  Offline: There is no command and response available between the CIM PC and the APS PC:  Online: There is communication between the CIM PC and the APS PC. This communication might be limited depending on the state of the OperationMode variable

OperationMode: Refers to how measurements data is acquired the OperationMode variable can also be in one of two states:  Auto: All measurement and control of the equipment is performed using ithe CIM computer  Manual: All measurement and control of the equipment is performed with the User Interface of the Axometrics Production Software Based on the value of the Mode and Operation Mode variables the system control is shown in the following table:

Mode OperationMode Comments Perform Change Repor Create Measurement Recipe t Data Recipe to CIM Online Auto System Completely Controlled By CIM CIM CIM Yes No Online Manual System is controlled by user, but data and User User Yes Yes status are reported to CIM Offline Auto Disallowed - - - - Offline Manual System is controlled by user, but data and User User No Yes status are not reported to CIM

4.4 TCP Communication

Once the Axometrics Production software starts, it creates a listener on TCP port 50,000 (0xC350). The software will only allow one connection (Client) at a time. After a connection is established, the APS software continuously listens for commands on this port.

The table below shows the basic specifications for communication with the APS Software.

Item Specification Protocol TCP/IP Physical Layer Ethernet (IEEE 802.3) Communication Speed 100 Mbps (or higher) Topology One Connection Communication Port 50000 IP Address 10.0.0.20 Message Format Ascii Command Serial Number 0001-9999 Meas. Data Format *.csv file Meas. Data Transfer Shared Directory Connector RJ-45 (8-pin)

55 Typically, the APS Software acts as a server. Typically, it receives an incoming command from the Client software (the CIM software in this case), processes the command, and returns a response

If the APS Software receives an “ENABLE_STATUS” command, then the software will also send Status Message updates to the Client automatically any time there is a change in the instrument status.

4.4.1 COMMAND FORMAT

All commands and responses are sent in ASCII text format.

The command format is:

STX Serial Number (4 char) Command or Response ETX 0x02 0x03

All messages and responses begin with a “Start of Text” character (‘STX’ = 0x02 = CHR$[02] ) and end with an “End of Text” character (‘ETX = 0x03 = CHR$[03] ). The ASCII text between the STX and ETX makes up the command or the response.

A serial number 0001 through 9999 must be prepended to the message by the client (sender). The serial number is included on the response sent back to the client. The serial number 0000 is reserved for the automatic Status Messages send to the client from the APS Software.

EXAMPLE: To send the ‘ONLINE’ Command and receive the ‘OK’ response, the Client and AxoScan would send the following ASCII characters:

Command (Client → AxoScan) ‘STX’1234ONLINE‘ETX’ which is bytes:

STX Serial Number Command ETX 0x02 0x31 0x32 0x33 0x34 0x4F 0x4E 0x4C 0x49 0x4E 0x45 0x03

Response (AxoScan → Client) ‘STX’1234ONLINE_OK‘ETX’ which is bytes:

ST Serial Number Response ET X X 0x0 0x3 0x3 0x3 0x3 0x4 0x4 0x4 0x4 0x4 0x4 0x5 0x4 0x4 0x0 2 1 2 3 4 F E C 9 E 5 F F B 3

Once AxoScan receives the ‘STX’ it will begin adding incoming characters to the command. If another ‘STX’ is received before the ‘ETX’ then previous command is deleted and a new command is started

4.4.2 RESPONSE MESSAGES

56 The response to most of the commands given in the table above will be of the form of a command echo followed by and underscore character “_”(0x5f) and then the response in the form given in the table above.

For Example, the command:

0002GLASS_ID=ABC4321DE would generate one of the following responses:

0002GLASS_ID=ABC4321DE_OK or 0002GLASS_ID=ABC4321DE_ERR=0202

Additionally there are six additional response messages that are defined below:

1. Operator Message

When the CIM computer issues the GET_OPR command it is in the following format.

0002GET_OPR

This will generate a response which includes the operator message. The response will be in the following format

0002GET_OPR_{0x0D}{0x0A} [OPERATOR] {0x0D}{0x0A} OperatorID=123123123{0x0D}{0x0A} OperatorLevel=Engineer{0x0D}{0x0A}

Note: the two hex characters ({0x0D}{0x0A}) shown in green are the carriage return/line-feed (CR/LF) characters received when getting a multi-line response. Henceforth, the (CR/LF) characters will not be shown, and it will be assumed that multi-line responses from the APS computer will always include the CR/LF

4.5 Alarms and Warnings

Note: Alarms and warnings only occur when a Sensor Suite is connected to the Panel Mapper Software.

Depending on the system configuration, several different alarms and warnings can occur during the software operation.

The following definitions are used to differentiate between Alarms and Warnings:

Alarm: An alarm means that the system is in an abnormal state. When an alarm is triggered, the system is either automatically shut down, not functional, or there is risk that incorrect measurements might occur. (Example: the Emergency Stop Button is pressed)

Alarms have three levels of severity, which are used to determine how the CGM reacts to the Alarm.

57 Alarm level Reset Procedure Condition after Reset 2 Full hardware and software restery needed Measurement aborts and must be started over 1 User must press button on CGM software Measurement aborts and must be started over 0 Resets automatically when alarm condition clears Measurement continues from where it paused

Warning: A warning means that the system is operating properly but a warning is issued to inform the CIM computer that the CGM is in a state where certain operations are un-safe to perform. (Example: the robot forks are in the CGM).

Each Alarm and Warning is given a unique 5 digit code. The code is as follows

1 1 005

Chapter 10 shows the list of possible alarms on the system. ( A complete list is dependent on the exact hardware configuration of the system)

All the current alarms and warnings are shown on the Factory control Tab of the the Panel Mapper software

Whenever a level 1 or a level 2 alarm occurs, a user acknowledgement is required to restore the system to a ready state. The following warning box appears that allows the user to acknowledge the alarm. If the Panel Mapper software is controlling the signal tower and audio alarm, the signal tower will flash and the alarm will sound until the user presses the Acknowledge button. If the alarm is still present, the system will go into a “down” state (red light not flashing, no audio alarm). Note: The system will not return to a “ready” state until the condition that caused the alarm has been resolved.

58 4.5.1 ALARM LOG

If a log file has been configured in the Production Software Settings (See Section Event Logging) then the alarms and warnings will be logged to that file as they occur.

[Production Line Communication] Alarm Log Path= "/C/AxoView/Current Version/Alarms.log"

4.6 System States The system states are based on the status of the PLC sensors, and machine status. The system State is determined by the following four values in the [Machine Status]

Ready to Measure: (TRUE or FALSE) Determines whether the system can receive the “Measure” Command from the CGM. If Ready to Measure is FALSE, an Error will Result from the CIM sending a “Measure” Command.

Safe to Load: (TRUE or FALSE) determines whether it is safe for a panel to be loaded into the system.

Safe to Unload: (TRUE or FALSE) determines whether it is safe for a panel to be unloaded into the system.

Measurement Complete: (TRUE or FALSE) tell when a measurement has been completed successfully. This value stays TRUE until the panel is removed from the system, or a subsequent measurement is attempted and fails.

Whether these values are TRUE or FALSE is determined by the sensors and logic in the system. The table below shows a typical example of how the system states are determined. The actual sensor logic that will determine the system states will change depending on the measurement system. However, only the four values in the system state need to be monitored to determine the action that needs to be taken to prepare the system for a measurement (load and remove samples, initiate measurements etc).

The system states can be monitored, either by software communication by sending the ‘GET_STATUS’ command. or they can be monitored through the PLC connection by reading the following PLC channels.

Channel Purpose Y2B Safe to Load Sample Y2C Safe to Measure Y2D Ready to Measure Y2E Measurement Complete Y2F Safe to Unload Sample Since these channels are wired to an output module, the system can further monitor the hardware state of these three PLC channels.

An Example of the system state during a typical sample loading/measuring/unloading sequence is given below.

Additional state diagrams for systems with a PLC are given in Section Error: Reference source not found.

4.6.1 USING THE AUXILIARY DAQ CABLE

60 When the Axometrics Hardware does not include a PLC, the Axometrics Production Software cannot use hardware sensors to determine System States. Therefore when the system states are reported to the client software it will be assumed by the production software that Safe to Load = TRUE and Safe to Unload = TRUE unless there is a measurement in progress. Furthermore, provided the system is not in an Alarm State, the production software will always be in a state of Ready to Measure = TRUE unless a measurement is in progress.

61 5 USER ACCOUNTS

To operate the AxoScan PanelMapper software, a user login is required. A user can log-on either by pressing the User Log-On button on the front panel, or by swiping a keycard on the reader attached to the Panel Mapper system (for systems that are equipped with a key-card reader). If the user presses User Log-On on the front panel the software will prompt the user for a Username (or User-ID) and a password.

Currently there are three possible user accounts.

1. Engineer – The Engineer account level gives the user complete access to the instrument and all of it’s functionality.

2. TA2 (Technician Account Level 2) – This is a Technician Account level that gives the user limited access to the functionality of the instrument (Limited to performing measurements, and changing between pre-set measurement recipes)

3. TA1 (Technician Account Level 1) – Currently this account has the same access as the TA2 level.

The following table shows the access and functionality of the system based on the Account Level of the user that is logged in.

If the user presses the Add User button, or the Edit User button, the following window appears allowing the user to edit the account settings.

62 There are two options for the Log-On Security Requirement. Only Password – When this option is selected, all of the user names are shown in pull-down menu. All that is required is that the user enter the appropriate password.

Username and Password – When this option is selected, the user must enter both the correct username and password to log-on to the system.

63 All of the user account information is stored in a file (APMAccounts.ini). The path to this file is configured in the AxoScan Panel Mapper.ini settings file (See Chapter 9)
