PT-100 sensor showing value 32767

[Juho Sainio]

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.

Terminals 7 & 8 are Analog Input 1, not Analog Input 0. Just move your wire connections over to 5 & 6.

I was tunnel visioning while following the "IO Webinar" youtube video. Now it works!😄 Thank you for the quick reply.
