Hello,
I'm using AB Control Logix 5580 with rslogix 5000.
I have one transmitter, that is wired to 2 AI modules (both on channel 3), just for redundancy reading. There is a resistor on the inputs. There is other transmitters on the AI modules as well.
We have an alarm if the inputs differ by 200. We are constantly getting this alarm. We checked the wiring connections and ohm the wiring. All is good.
The other transmitters is setup the same, yet we don't get this difference alarm.
Any reasons for the difference if both AI is coming from the same transmitter?
Thanks,
