Functional description

The functionality of the RTU is defined by means of standard software that is delivered with each RTU. The software is located in Flash memory on the Central Processor Unit board. All application software is written in ANSI C language using a strict modular design around the multi-user, multi-tasking real time operating system in such way that only configuration is D01-MRTU backview typical layout needed to set up the RTU for its specific task.

The design of the D01 system is driven towards reliability and versatile functionality that is required for the toughest remote System setup and configuration and unmanned conditions. Therefore components have ample specifications and modules have sustained long “burn-in” Extensive configuration, local as well as remote, is possible by tests in order to limit breakdown to a minimum. Furthermore using the RTU Manager. For the larger projects a central the system does not have any moving parts like disks and fans configuration database Action can be used independently or so that mechanical damage can not occur. The design is as part of the Datawatt WinCoach software suite. This realised in HCMOS technology that results in high degree of database contains the configuration information of all RTUs of insusceptibility for external interference, a low power a project or system.

Telecontrol functions

The telecontrol functions of the RTU handle the communication and signal status exchange procedures between the RTU and its central system and are based on the international open standard protocol IEC60870-5-101. The D01 RTU is furthermore equipped with the IEC60870-5-104 protocol. The 104 companion standard defines the same application layer as used for 101 protocol but in this case for communication using TCP/IP transport layers. These protocols handle many procedures for the reliable and consistent exchange of data and describe the data formats. Accurate time synchronization and reliable command procedures are part of it.

Conversion to flow or power Flow and power can be derived from accumulated amounts Metering functions by calculating the differences per interval. These differences can be recorded in the real time status memory as well. For remote fiscal metering D01-MRTU’s have special Different intervals may be chosen. The values can be used for functions on board that enable the performance of complex transmission to the host as well as for data logging purposes. flow, power and energy measurements retrieved from fiscal meters. Metering protocol IEC62056-21 This former IEC1107 protocol full fills the VDEW2.0 requirements and is implemented on the D01 to readout energy meters either point to point or point to multi-point on one or more RS485 interfaces. This protocol is widely used on many power meters, heat meters and volume correctors. Up to 10 meters can be connected to one RS485 bus. Datawatt will time synchronize the connected meters and will do the real time scanning of the selected registers. Apart from real time readout the last stored values of the load curve can be retrieved to enable equal time read out of all metering values. These equal time readings are the bases for near time fiscal monitoring systems in complex energy demand and management processes. Individual differences between protocol implementations may exist and register selection is required to limit read out time so that customer specific configurations may be required. Typical metering example for gas production Main and check (backup) meter comparison Counter value registration Main and check meter may be compared based on the The MRTU accepts metering pulses or serial information from following: both meters deliver values to the outstation. After a power meters, flow computers, volume correctors and other preset increase both values are compared. The difference intelligent electronic devices (IED). In case of serial between the two may not exceed a preset value. The increased information, it is required to run the meter protocol as a value as well as the preset difference may be entered into the separate process on the outstation. Many metering protocols configuration of the MRTU. Exceeding the preset difference have already been implemented so that a wide variety of value leads to an alarm. In case only one meter is selected to connections is available; others can be implemented. They are record values for transmission the change over between main available on request. and check meter can be done manually or automatically.

The pulses are accumulated in 8 digit registers (28 bit) and put Aggregation of flows and totals in to the real time status memory of the RTU. Meter values that Both flow as well as accumulated values can be used in free to come from meters with serial interface are put in the real time configure aggregation calculations. The values can be added status memory as well. In this way the accumulated amount of or subtracted and the resulting value may be put in the real kWh electricity or m3 gas are measured and can be used for time status memory as a separate value. The result can be data logging purposes or for transmission to the central station. used for data logging purposes and for transmission to the central station.
