Everything is working, there is no error, but PT100 does not read the value and I cannot enter the value in the tiaportal, it only shows 3276.7 and this value does not change. what is the reason of this ? I am using TIA portal V14 ------------------------------------------------------------------------------------------ Split from Error Checking RTD PT100.

I couldn't figure out which color wire to connect where, but I did this by trial and error. When I changed the cable location, the rtd leds turned red. So with this wiring it is green and does not give any errors. But as I said, PT100 does not read any value and I cannot enter the value from the tia portal. Could this be because the RTD card version is not compatible with Tia Portal V14? Thank you very much Attachment WhatsApp Image 2023-10-31 at 12.58.41.jpeg (573 Downloads)
