Configuring Genius I/O Blocks

Genius I/O block configuration for a GMR system is similar to configuration for a

non-GMR system. You should refer to the Genius Discrete and Analog Blocks User's Manual for specific configuration instructions.

A copy of the configuration prepared with the GMR Configuration Software should be used for reference during block configuration, to assure consistency.

Editing the Reference Addresses

For Genius blocks in a GMR system, blocks within a group use the same reference addresses in each of the redundant PLCs, so these are not changed.

Editing the Block I/O Type

Any discrete block that is part of a redundant input group (triplex, duplex, or simplex) must be configured as a ªcombinationº I/O block.

Copying Configurations

Because the blocks in a redundant input or output group usually have the same configuration, it would be most convenient to copy configuration from one block to another. However, the Copy Configuration feature of the Genius Hand-held Monitor only works when blocks are online on the same bus (and GMR blocks in a group are on separate busses). Of course, it is possible to use the Copy Configuration feature between similar blocks on a bus that are not in the same group.

Setting Up Blocks for Fault Reporting

Configuring a block for CPU Redundancy = GMR automatically sets up the block to send three fault reports when a fault occurs; one fault report each to serial bus addresses 29, 30, and 31. The blocks require no further setup to send multiple fault reports.

Setting Up Non-GMR Blocks to Send Multiple Fault Reports

Inputs-only blocks automatically send up to two Fault Reports to serial busses 30 and 31. However, non-GMR output and mixed I/O blocks must be configured for Hot Standby redundancy to send two Fault Reports to serial bus addresses 30 and 31.
