First, from the Analog extension configuration screen, select PT100 for the Input IJ:

Then, a GAIN function block is needed to apply the following formula :

T° = (( IJ x 150 ) / 1023) - 25

because the scale is:

-25°C => IJ=0
+125°C => IJ=1023

In consequence, the GAIN function has to be configured like below:

In Monitoring, we can see the read temperature is 24°C when the input value is 337:

Wiring:

• 1rst red wire connected to IJ
• 2nd red wire connected to Pt
• White wire connected to 0v
