C200HS->AD001-> Temp sensor

[Shaynet]

Hey all.

I'm trying to fault find an issue with a temp sensor.

 

It's connected via an AD001 slot and a 4-20ma transmitter 

It has worked in the past but now showing a zero value in the memory. I'm after help trying to isolate the issue is it the sender, AD001 or wires.

Cheers,

Shayne

One of the i/O words has bits to indicate disconnection.

Hope this  helps.
