Cause : Analog input wire breakage comes when the wire-break monitoring for an analog input has responded. The input current of the analog input has exceeded the threshold value parameterized in p0761[0]. p0756[0]: analog input 0 (X131.7/X131.8).
- Check the wiring to the signal source for interruptions.
- Check the magnitude of the injected current - it is possible that the infed signal is too low.
- Check the load resistor (250 Ohm).
