3 wire RTD is not bad. But you need to connect 4 wires to the module. So 1 additional wire required as bridge.

Well, TC give temperature delta to reference junction. To get absolute T value you either put cold junction in bucket with melting ice or use RTD to measure cold junction or use compensating wires (which made of same material as TC) thus moving cold junction to PLC clamps (and use internal compensation routine).

Hello,

Glad it works, but it's not only devide by 10

convert to real first and then devide by 10.0

L "analog in" ITD DTR L 1.000000e+001 /R T "temp_out"

Temp out is a real, so a DW.

Regards,

Marcjan

I know, but, i only need send INT Value to read on Magelis HMI (Profibus), on Magelis i will divide by 10.
