Hello. 

I need your help. I have used Tia Portal for programming S7-300 plc. Transmitter is 2 wired and i have measured is sends me output signal. But i can't see it on tia scale module. For your information i have put the black switch in D position from back side of AI module. Also i wrote logic in simatic manager and it worked without any problem. But I don't know what is an issue in tia portal. and also simulation mode also works in Tia. But on online mode i can't see any signal. Please check pics in attached files.

CPU model: 6ES7 315-2EH14-0AB0

AI model :6ES7 331-7KF02-0AB0

Closed cause question posted twice.

The second thread with the subject S7 300 Analog module doesn't give signal is published within the conference SIMATIC S7-300 / S7-300F.
