For my project I required two PLCs, one of which reads a IR thermometer. The second PLC needs that value, so I made the first write an Analog signal so that in theory I could capture the signal on the second and convert it back into the value I needed.
The problem I am having is that the 1st writes a perfect signal, with minimal error, however I can't seem to get the 2nd to pick up the analog signal successfully. The signal cycles through 0 to 4096 continuously. I anticipate a wiring error but I've tried almost everything.
Has anyone been able to get a TRI PLC to read an external analog signal before? I've done it many times with potentiometers and other sensors using the ground and Vs, but I have hit a wall this way. Thanks for any help!
