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).

Genius Device Number of
the I/O device(s) that
should send extra fault

In the event only selected blocks should report their faults to the
assigned monitor, program separate Assign Monitor commands for
each, entering a different SBA in this field each time.

Genius Device Number of
the bus interface device
that will RECEIVE the extra
fault reports.
0-31: the SBA of the receiving Genius Device (i.e. the Assigned
Monitor).
