COMMREQ #7: Assign Monitor Command

An Assigned Monitor is an additional bus interface module (usually in another PLC) that
monitors Genius I/O devices on the bus. Remote I/O Scanners and I/O blocks broadcast their
inputs to all devices on the bus. Therefore, any interface module on the bus will receive all
inputs sent by the blocks. However, blocks direct fault reports and configuration change
messages only to the bus interface module that sends them outputs. Blocks configured for
CPU Redundancy will automatically transmit two copies of any fault report or configuration
change message, directing them to Device Numbers 30 and 31.
The Assign Monitor command can be used to have Genius I/O devices send extra fault report
and configuration change messages to a monitoring bus interface module. Blocks would
send two copies of each fault report or configuration message in a non-redundant system.
Blocks in a redundant system would send three (two to the redundant bus interface
modules, and the third to the Assigned Monitor).
6 This enhancement (use of 255 as Genius Device Number) requires that the supervising PNC001 firmware be version 2.11 or later;
otherwise the COMMREQ command will fail. If CPE330 is used, firmware version 8.80 is required. If CPE400 is used, all firmware versions
support this functionality.
