83SR07D-E GJR2392700R1210 Control Module
Application
This 83SR07D-E module can be used to implement input and processing module redundancy in the PROCONTROL system. As a supplement to the updated module description for the module 83SR07-E/R1210, this document focuses on the module's redundancy-related features.
Features
Processing is performed in parallel in the on-line and standby units. When a redundancy switchover is effected, this results in a bump less transfer of the processing functions to the standby unit. This bump less changeover is ensured by synchronizing the standby unit with the on-line unit by means of synchronizing telegrams.
Both on-line and standby units are self-monitoring. Any disturbances within the modules are signal led to the appropriate redundancy control module 88TR01 via the SSG line.
All process connections (connectors X21) of the individual modules belonging to a redundant pair are connected in parallel by appropriate wiring in the station.
The input resistors (burdens) are connected in the on-line unit and disconnected in the standby unit. This is also true for the process outputs and for the transducer and contact supplies from the module.
For diagnostic purposes, standby units transmit a sign-of-life telegram on the bus.
Addressing
Sign-of-life telegram
On-line units transmit all telegrams as structured in the address list. Standby units transmit a sign-of-life telegram for diagnostic purposes. This is always register 0. If register 0 has been structured in the address list, the process telegram is transmitted with the appropriate data type. If register 0 has not been structured, a default telegram with data type 0 is transmitted. The sign-of-life telegram is transmitted cyclically.
Diagnosis
The module's hardware and software functions are monitored. The signal ling and monitoring concept is shown in Fig. 1.
All annunciations are signal led via the SST line and indicated by the ST lamp on the module's front panel.
When a module's SSG line is activated, this is interpreted as a module disturbance by the redundancy control module 88TR01 and indicated by the SG lamp on the module's front panel.
