Setting Up Blocks to Report Genius Faults

By default, most Genius blocks, including the types of blocks normally used in GMR systems, send only one copy of a Fault Report. For a GMR system, blocks can be set up to send additional Fault Reports. The setup needed for a block depends on two things: what type of block it is, and how many PLCs should receive its Fault Reports..

Setting Up 16- and 32-Circuit DC Blocks to Send Multiple Fault Reports

A 16 or 32 Circuit DC Sink/Source block (only) will send three Fault Reports, one each to serial bus addresses 29, 30, and 31, if set up in either of the following ways:

HFor blocks in a GMR group, block configuration is CPU Redundancy = GMR

HFor non-GMR group blocks, block configuration is CPU Redundancy= Hot Standby. Hot Standby is selected on ªNon-Voted I/Oº screen of the GMR configuration software.

Setting Up Other Blocks to Send Multiple Fault Reports

Other blocks may also send ªextraº copies of Fault Reports.

HInputs-only blocks automatically send two Fault Reports to serial busses 30 and 31 with no additional configuration.

HOutput and mixedI/O blocks configured for CPU Redundancy = Hot Standby will send two Fault Reports to serial bus addresses 30 and 31.

HIf the block is configured in the GMR configuration, the GMR software issues an ªAssignMonitorº datagram to cause a block to send the third fault report.

Summary Table

The following table summarizes how many Fault Report messages are sent by blocks configured for different types of CPU Redundancy, with or without the Assign Monitor datagram. X means the feature is not configurable for that block. (Page 6-50 describes configuring Genius blocks for Fault Reporting)
