Problem with Pt100 measurement

Hello, ABB.

I'm having trouble with a Pt100 measurement.

I'm using a PM554 PLC with an AX522 I/O module. I wired the Pt100 as shown in the user's manual (- to 2.0, + to 2.1 and return to 1.0). I also configured channels 0 and 1 (as indicated on the manual) to read Pt100 3-WIRE -50.0...400.0°C. I'm taking the reading on the PLC from channel 1.

However, when reading the INT value, I get a very low number (equivalent of -44°C), even though I'm currently at approximately 25°C.

I'm not sure if this is a scaling problem. I've programmed the reading of the INT value to be scaled to a REAL by using a 0 to 27648 scale, according to the manual (see attached image).

What could be causing this? I already changed the Pt100 and have the same problem.

Thanks!
