Troubleshoot Redundancy

When a fault or other event occurs, use these methods to determine the cause:
  • View diagnostic information in the Logix Designer application.
  • View redundancy module events and status by accessing logs in the Redundancy Module Configuration Tool (RMCT). Each partner redundancy module keeps its own events in separate logs.
  • View and clear redundancy module faults.
  • Check the status messages and status indicators on the front panel of the redundancy modules. See 1756-RM3 Status Indicators.
  • If Front Port Crossload mode is enabled, use MSG instructions to access front port crossload diagnostics.
