Troubleshooting Appendix B
Error Codes
This section lists possible error codes for your controller, as well as recommended
actions for recovery. Information about the fault is stored in a fault log, which can
be accessed from the Diagnostics page in Connected Components Workbench
software. The fault log contains brief information about the last fault, and
detailed information about the last 10 non-recoverable faults that occurred.
If an error persists after performing the recommended action, contact your local
Rockwell Automation technical support representative. For contact information,

Fault Types
There are two basic types of faults that can occur:
• Recoverable – A recoverable fault can be cleared without having to power
cycle the controller. The fault LED flashes red when a recoverable fault
occurs.
• Non-recoverable – A non-recoverable fault requires the controller to be
power cycled before clearing the fault. Non-recoverable controller faults
may become recoverable after the controller has been power cycled, or an
automatic reset is performed by the controller. If the controller performs
an automatic reset and the fault becomes recoverable, the fault will not be
logged. After the controller has been power cycled or reset, check the fault
log in the Diagnostic page of the Connected Components Workbench
software, then clear the fault. The fault LED is solid red when a
non-recoverable fault occurs.
