We had a new installation with Control Logix L81 which uses 2 of the 1756-IR12. Using Studio 5K Ver.30
We are facing no readings at the terminal of both the cards. It is connected with 100 Ohm PT385 RTD's [2 wire]. There is no fault displayed at the card, but the channels report a fault, with the underrange triggered true as well. The data is showing -200 Deg C, which is the lowest of the cards range. I think the card is not getting the field device into it. Tried with terminal B and C of each channel, link with and without a jumper as well, no difference
Contacted the Rockwell Tech connect as well as the local tech support, the problem still persists. Tech support advice to connect a 100 ohm resistor and see it reads 0 Deg C, tried that, but no response as well. Now the local tech support had bought back one of the card to their lab for testing. Anyway I have put up an order for a new card, as the project can't wait.
I noticed there are a 2 rows of 7 pin pairs on the card's PCB [as in the image below], which do not have any jumpers on it, can anyone please help to verify, is it suppose to have a jumper on it or left it open. Or any other advice for me to solve this issue.
Thank You
Best Regards
