TCs connected to ADU257 module on Modicom PLC all are reading Zero. Software is IN Touch - WindowViewer; Observations: TCs pluged in; All LED lights indicate normal on PLC, processor, etc.; power supplies okay; fuses okay on PLC; Re-booted PC; If you disconnect a TC, it still reads 0.0C. (should read 409.5 indicating an open TC); Loop controlers work okay on PLC.
Any ideas what is going on?
(Note: I'm out of my field - mine is chemistry!)
Thank you,
