Hello, I'm using a analogue module 6ES7 331 7KF02 0AB0 for 4 to 20 mA transducers and a 6ES7 331 7KF01 0AB0 for 3 wire PT 100 sensors. In the 4-20 mA I get in all the channels overflow lectures, and in the PT 100 I get ZERO in all the channels. I want to know if there is a wiring problem or is a card problem. I wired the sensors as shown in the S7 300 Module data manual.


Regards
Victor.

Hello

Did you ajust black squares on the side of cards depends from 2 or 4 wires transducer?

Hello Aret

This is how is wired the 7KF02 module: P1 thru P4 are two wire pressure transducers. VD1 and VD2 are linear transducer using 3 wire connection. For this type of transducer I'm installing the block in the 4 wire position
