The PMC detected an error in the user-defined safe I/O cross-check function. This indicates a discrepancy in the monitored user-configured safe I/O signals, potentially affecting user-implemented safety features. A power cycle is required.
Click steps to track your progress.
Examine the state of all user-defined safe I/O channels within the PMC.
Measure voltage at the PMC user I/O terminals.
Verify parameter P1-19 (PMC User I/O Configuration) for accurate setup.
Inspect the physical connections of user I/O devices.
Confirm the logic that drives or reads these user I/O signals.
