Message Interpretation
Major Fault TXX:CXX message A major fault of Type XX and Code XX has been detected.
For example, if the status display indicates Major Fault T04:C42 Invalid JMP Target, then a JMP instruction is programmed to jump to an
invalid LBL instruction.
I/O Fault Local:X #XXXX message An I/O fault has occurred on a module in the local chassis. The slot number and fault code are indicated along with a brief description.
For example, I/O Fault Local:3 #0107 Connection Not Found indicates that a connection to the local I/O module in slot three is not open.
Take corrective action specific to the type of fault indicated.
I/O Fault ModuleName #XXXX message An I/O fault has occurred on a module in a remote chassis. The name of the faulted module, as configured in the I/O Configuration tree of
the Logix Designer application, is indicated with the fault code and brief description of the fault.
For example, I/O Fault My_Module #0107 Connection Not Found indicates that a connection to the module named ‘My_Module’ is not
open.
Take corrective action specific to the type of fault indicated.
I/O Fault ModuleParent:X #XXXX message An I/O fault has occurred on a module in a remote chassis. The module’s parent name is indicated because no module name is configured in
the I/O Configuration tree of the Logix Designer application. In addition, the fault code is indicated with a brief description of the fault.
For example, I/O Fault My_CNet:3 #0107 Connection Not Found indicates that a connection to a module in slot 3 of the chassis with the
communication module named ‘My_CNet’ is not open.
Take corrective action specific to the type of fault indicated.
X I/O Faults I/O faults are present and X = the number of I/O faults present.
In the event of multiple I/O faults, the controller indicates the first fault reported. As each I/O fault is resolved, the number of faults
indicated decreases and the next fault reported is indicated by the I/O Fault message.
Take corrective action specific to the type of fault indicated.
