Hi, to be start with, I am having a two pump system hookep up with S7 200 Microwin. There were 2 unit of sinamics G110 drive attached to PLC with USS RS485 communication.

I replaced one of the drive to Sinamics V20 model today and set bus address and other parameter follow my old Sinamics G110.  However, my system does not start and there is no any error msg on sinamics V20.

Do I miss anything while do the conversion?

Closed cause question posted twice.

The second thread with the subject Microwin communication with Sinamics V20 is published within the conference SIMATIC S7-200.
