ABB 88TR01 GJR2391100R1210 Redundancy Control Module

88TR01 GJR2391100R1210 Redundancy Control Module

In a PROCONTROL station, the 88TR01 redundancy control module is used for redundancy applications.

The redundancy control module

· recognizes redundancy-relevant disturbance signals issued by redundant modules of its own redundant  station, monitors the proper functioning of the modules of its own redundant station.

· monitors the proper functioning of its own redundant station on the remote bus.

· monitors the redundant stations for identical configuration, and 

· monitors its own essential module functions.

Whenever a redundancy-relevant monitoring function does respond, this module will - in conjunction with the redundancy control module of the other redundant station - effect a redundancy switchover.

When a station is used as a redundancy, the station's address may be within n=1 to 121. In that case station address n+128 must not be used by any other station.

Features

The redundancy control module uses a standard interface with the PROCONTROL station bus. Connection with the redun-dant modules is established by the printed station-bus circuit board.Connection with the other redundancy control moduleis established through the partner interface on the lowered ge-connector of the module as well as via the PROCONTROL bus.

By their parity bits, the telegrams received from the bus are checked by the module for fault-free transmission.

The telegrams sent from the module to the bus are provided with parity bits. This ensures fault-free transmission.

Disturbances in the module, disturbances in the redundant station, and the module state are indicated by light-emitting diodes (ST, SG, SR, DF, BE, AK) located on the module front.

The redundancy control module continuously scans the state of its redundant station. Should a disturbance occur in its ownredundant station, the module will effect a switchover. in case the other redundant station is not fault-free, a switchover will not be made.
