Output relay warning

What does A881 mean?

This warning is generated by an edge counter, likely configured to monitor the number of operations or switching cycles of an output relay. An auxiliary code in the event log will specify which edge counter triggered the warning. Excessive relay operations can indicate a control issue or impending relay failure.
