Output Fault Handling
When an output fault occurs, a port fault alarm occurs. Fault recovery is automatic;
when the fault is no longer present, normal operation continues. To prevent
"bouncing," or reporting errors continuously, the module increments an error counter
each time a port fault occurs. If the error count exceeds a preset threshold, then the
faulty port is disabled. You must disable and then enable the port using software
commands to return it to normal service. The error counter automatically resets
when there are no errors in 24 hours.
The port status message indicates the state of each port. The letter code for each
port is as follows:
F – port fault
N – port is disabled
blank – port is in normal service
The following example shows port 5 with an internal port fault, port 7 with an
external port fault, and ports 10, 11, and 12 disabled.
