12.5 Controller Fault Table

Most error conditions involving the Ethernet interface generate faults in the Controller Fault table. The table on
the next two pages lists Ethernet interface faults and corrective actions.
To access the details of a Controller Fault Table entry, double-click the Fault Table entry and the details are
displayed as "fault extra data". Refer to Online Help in the PLC programming software for more information.
An example of the fault extra data is shown below:
For Ethernet Interfaces the leftmost 14 digits of fault extra data (underlined in the example above) show the
corresponding log Events (2 digits) and Entries 2, 3, and 4 (in that order, 4 digits each).
The example above is reporting
▪ an Event 16,
▪
Entry 2=6,
▪ Entry 3=3, and
▪ Entry 4=5.
This information can be used to refer directly to detailed fault descriptions included in the Exception Log Event
tables in GFK-2225, TCP/IP Ethernet Communications for PACSystems Station Manager Manual. (In that
document, refer to Appendix B, Exception Log Events.)

Check to make sure that the logic application is not sending COMMREQs
faster than the Ethernet Interface can process them. Reduce the rate at
which the application is sending COMMREQs to the Ethernet interface. If
problem persists, contact Technical Support.

Check for valid COMMREQ command code. If problem persists, contact
Technical Support.
Try to validate the operation of the remote node. If problem persists,
contact Technical Support.
Error reported when message received where IP/MAC address cannot be
resolved. Error may indicate that remote host is not operational on the
network. Check that remote host is operational on network and its
addresses are correct.
