ABB 81EU01G-E GJR2391500R1210 Universal Input Module

81EU01G-E GJR2391500R1210 Universal Input Module  

Functional Description

The 81EU01G-E module can be used in PROCONTROL redundancy applications for input and processing modules. This description is intended to supplement the applicable module description for module 81EU01-E/R1210 with information on the redundancy-relevant properties of the module.

Features

· Processing is performed on the active and on the non-active module in parallel. In the case of a redundancy changeover, the non-active module takes up processing in a bumpless take-over. Bumpless condition is ensured by dual acquisition and processing of the input signals.

· Active and non-active modules are self-monitoring and signal module disturbances to the respective 88TR01 redundancy control module over the SSG line.

· All process connections (connector X21) of the redundant partner modules are connected in parallel through the station wiring.

· The input resistors (loads) are switched on for the active module and off for the non-active module. The contact and transducer supplies are on for both modules.

· For diagnosis purposes, non-active modules send a live-sign telegram to the bus.

Structure, address and limit-value list

For redundant operation all lists of the module (structure, address and limit-value list) must be identical on both redundant modules. This can be ensured by the user with the help of the PDDS.

Simulation

For redundant operation, the signals of the redundant modules have to be simulated identically. This is also done from the PDDS.

Checksum

For all active lists (structure, address and limit-value list) in the EEPROM or RAM as well as for the module firmware, the modules generate a checksum. This checksum is used for monitoring the lists on active and non-active module for conformity. The checksums can be displayed on the PDDS.
