Series 90–70 Remote I/O Scanner User’s Manual – July 1992116
Display and Clear Faults from Logicmaster 90–70
The content of the PLC and I/O Fault Table displays depends on whether the
programmer is communicating with the PLC or a remote drop.
I/O Fault Table at the PLC
The content of the fault display at the PLC depends on the revision level of the Bus
Controller. With a Bus Controller that is version 4.0 or later, when a fault occurs on a
remote drop, the I/O Fault Table shows the Drop ID and the rack and slot within the
remote drop where the fault has occurred:
33#0.4
Drop ID
Rack
Slot
Remote Drop Fault

REPLACE
I/O Fault Table Display with a Rev. 3 Bus Controller
If the Bus Controller is a rev. 3 version, it cannot transfer to the PLC the detailed fault
information provided by a Remote I/O Scanner. Instead, a rev. 3 Bus Controller reports
any fault from a remote drop as a GENA fault.
Fault Clearing
To clear the fault table, press the Clear key.
