PID Feedback Supervision Fault (PID1)

What does 101 mean?

The feedback value for PID controller 1 is outside the configured supervision limits (P3.13.6.2 and P3.13.6.3) for a specified delay (P3.13.6.4). This indicates a deviation from the expected process variable feedback, suggesting an issue with the process or the sensor. It can lead to incorrect control actions and process instability.
