Section 3: I/O Fault Table Explanations The I/O fault table reports data about faults in three classifications:
• Fault category.
• Fault type.
• Fault description.
The faults described on the following page have a fault category, but do not have a fault type or
fault group.
Each fault explanation contains a fault description and instructions to correct the fault. Many fault
descriptions have multiple causes. In these cases, the error code, displayed with the additional fault
information obtained by pressing CTRL-F, is used to distinguish different fault conditions sharing
the same fault description. (For more information about using CTRL-F, refer to Appendix B,
“Interpreting Fault Tables,” in this manual.) The Fault Category is the first two hexadecimal digits
in the fifth group of numbers, as shown in the following example.
02 1F0100 00030101FF7F 0302 0200 84000000000003

The following table enables you to quickly find a particular I/O fault explanation in this section.
Each entry is listed as it appears on the programmer screen.
Loss of I/O Module The Fault Category Loss of I/O Module applies to Model 30 discrete and analog I/O modules.
There are no fault types or fault descriptions associated with this category. The fault action is
Diagnostic.
Description: The PLC operating software generates this error when it detects that a Model 30
I/O module is no longer responding to commands from the
PLC CPU, or when the configuration file indicates an I/O module is to
occupy a slot and no module exists in the slot.
Correction: (1) Replace the module.
(2) Correct the configuration file.
(3) Display the PLC fault table on the programmer. Contact GE Fanuc
PLC Field Service, giving them all the information contained in the
fault entry.
