Juho Sainio Posted November 28, 2021 Report Share Posted November 28, 2021 Hello, I have a problem getting a pt-100 3 wire sensor to work with my unitronics plc V350-35-TU24. Despite all of my efforts, it still shows the value 32767. Here is my setup right now: This is how the jumper settings should look like for pt-100: https://imgur.com/a/Q73WbcY Here is how they are on my plc: https://imgur.com/a/HAhDQpk This is how the pt-100 wire connection should look like: https://imgur.com/a/e55mO8O And the connection on my plc: https://imgur.com/a/vpn97Ld The software configurations look like this: https://imgur.com/a/EjbkioB And after downloading it to the plc, the online test shows the error value: https://imgur.com/a/SZrL3Eq I have also tried other wire connections like this one: https://imgur.com/a/6LuGb8q But this one also shows the same error value. The pt-100 sensor also works perfectly fine: https://imgur.com/a/6FzEM5d Is there something I'm missing? What should I try to get it to work? Thank you in advance.

MVP 2022 Flex727 Posted November 28, 2021 MVP 2022 Report Share Posted November 28, 2021 Terminals 7 & 8 are Analog Input 1, not Analog Input 0. Just move your wire connections over to 5 & 6. 1 Quote Link to comment Share on other sites More sharing options...
