The PLC and I/O Fault Tables in a GMR System
Faults and alarms from I/O devices, Bus Controller faults, and bus faults are automati-
cally logged into the Series 90–70 PLC’s I/O Fault Table. Faults can be displayed with
the programmer in either On–Line or Monitor mode.

Clearing the Fault Tables in a GMR System
Although the Fault Tables seem to operate as they would in a non-GMR system, they are
actually controlled by the GMR software, not the PLC firmware. Therefore, in a GMR
application, the fault tables must be monitored and cleared from the application
program logic.

Caution
Use these %M references to clear the PLC Fault Tables. Do not use the Logicmaster F9 key to
clear the Fault Tables.
clear the Fault Tables.
H To clear the PLC Fault Table in a single PLC, set reference %M12259 to 1 for at least
one PLC sweep in that PLC.
H To clear the PLC Fault Table in all PLCs, set reference %M12264 to 1 for at least one
PLC sweep in any PLC.
H To clear the I/O Fault Table and corresponding fault contacts in all PLCs, set
reference %M12258 to 1 for at least one PLC sweep in any PLC.
