I have a Omron PLC with CPM1A-MAD01 anaolog input output module its reading pt100 temperature probe. When the machine is running it starts to fluctuate like its getting electrical noise however i noticed when i disconnect the RTD Transmitter it reverts to 714degrees instead of going off scale (9999) like the other rtd's in system.
I am stumped where to look next, was thinking possibly faulty analog module as machine was and has been running fine. temp probes are good rtd transmitters are good.
