313C-Ptp (Ptp stands for point to point) can connect to 6RA70's, Masterdrives and Micromasters via USS. It doesnt setup like profibus and the Step 7 hardware config. The drives do have individual addresses like profibus but it uses the USS address settings. Also, USS is not as fast as profibus and you cannot do routing..etc. But for an inexpensive communication network for speed setpoints- it does work.
What is the application though?

If you need more info or a sample- post back

Many Thanks JRW,

How i see which data sedn to drivers from plc?

Many thanks

I dont understand your question.

For data sent from plc to drive see function diagram G170 (if using X300 USS interface 1)

For the plc function blocks do a search for DriveES Simatic
