Chapter 8  Diagnostics and Fault Clearing
PLC Fault Table at the Remote I/O Scanner
If the programmer is communicating with a remote drop and in on–line mode, the
PLC Fault Table shows the remote drop rack and slot locations of the module where
the fault occurred, and a description of the fault.
Faults on option modules (such as the PCM) are listed in the Remote I/O Scanner’s
PLC Fault Table.  Faults on I/O modules are listed in the I/O Fault Table.
