Status Indicators Appendix A
I/O Fault Codes
I/O faults indicated by the controller are indicated on the status display in one of
these formats:
• I/O Fault Local:X #XXXX message
• I/O Fault ModuleName #XXXX message
• I/O Fault ModuleParent:X #XXXX message
The first part of the format is used to indicate the location of the faulted module.
How the location is indicated depends on your I/O configuration and the
module’s properties specified in the Logix Designer application.
