i replaced the IO board and doesn't work, i have 4 PT100 and doesn't work with any , i just hace one connected with the PLC but i changed the PT100 input and was the same prpblem :c -
Hi, 1. Please check jumpers for good contact. *Take jumpers from other PLC for test. 2. It is not recommended to exchange board. Upside board store all calibration data for upside board. Downside board store all calibration data for upside board. B.R. -
If you have two similar PLC - then you can replace IO board for test what is wrong - PLC program or PLC IO hardware. By the way - you have two PT 100 input on SM35-J-RA22- do you test the same PT100 on another one? P.S. Maybe replace green connector is the solution? -
This is all a good result, but Mitchell, please note that you posted in the Unistream part of the forum. There are dedicated forum areas for different model types. The initial responses here were based somewhat on you using Unistream, which then turned out to be Vision after all. When you have another little hiccouph which we'll gladly help with, please ensure it is in the correct area. It's bad enough the regular responders getting confused as to where they are, let alone those asking the questions! 🤔 cheers, Aus -
the wires and jumpers are well connected, what could be wrong with the PLC?
