Data Transfer between S7-300 and Sinamics G120 Drive through PROFINET

HI,

I have a program with S7-300 PLC communicating with PILZ safety PLC and Sinamics G120 drives through Ethernet. How to identify the DB address which sends and receives the data between the PLC and sinamics drive by the IP address...

It matters how do you call communication fuctions and where you store the result, not necesarily it has to be a DB. It is described in the manual with examples:
