Determining Fault Type
When you are monitoring a module’s configuration properties in
RSLogix 5000 and receive a Communications fault message, the Connection
page lists the type of fault.
For a detailed listing of the possible faults, their causes and suggested
solutions, see Module Faults in the RSLogix 5000 online help.
Refer to the RSLogix 5000 AOP help to troubleshoot using the Module Info
tab, Internet Protocol tab, Port Diagnostics dialog, Time Sync tab, or Network
tab. Access the AOP help by clicking Help on any of these tabs.
RSLogix 5000 software generates 1s in
response to a module communication
fault.
In this example, a communication fault
occurred between the controller and the
module, so the controller automatically
writes 1s for all bits in the word.
