My Symax controller is reporting an offset from the measurement devices that are connected to it. This is only happening on one I/O module on all 16 inputs. I have checked for grounds by disconnecting each input and seeing if the offset goes away. After checking all of the inputs, I did not find the ground. Is there another test I can try before shutting down the processor and changing the I/O board?
