    Hi Joe, thanks for your response; I try your sugestion but the card didn't respond, also build a simulator to can test temps completally isolated from the system and the card either way didn't respond. I gess I will need a new one, Thanks again for your help.

    Hi everyone: We have a 350-35-TRA22 with a EX-1 and a IO-ATC8. The problem start when the system was restarted after last year, the thermocouple card was reading unusual temperatures then after that is start reading 0 in all the chanels. I change the thermocouple card with any advance, change the ex-1 and the cable with the same result; I put one of the thermocoules on the OPLC an I get the expected temperature (room temp. at this time), put back the thermocouple at the card still get 0, (card is configured for thermocouples). Any help will be graetly apreciated I run out of ideas.
