To replie to your answer : '
The recommended communication way between two CU320 is via Profibus via peer to peer coupling (slave to slave communication). This requires a master in the Profibus (e. g. S7-300 or S7-400).'
Does this mean that the S7 plc first has to read CU320 nr 1 and then has to write to the other CU320 and the other way arround?
In that case the communication won't be very fast. What I really appreciate in the CU320 is that links between data of different motors can be done in one cpu, f.i. to send actual for speed synchronisation. In the masterdrives that had to be done with f.i. Simolink between the drives.
Now this isn't necassary anymore : the drives are within one cpu. But what when not alle drives are within one cpu? Depending on the configuration and selection of vector or servo mode I believe ten drives in one cpu will be a very maximum. What to do if you want speed synchronisation with drives that are in another CU320?
Thanks

Has anyone an example or some more information on direct data exchange or internode communucation between two Sinamics drives? I would use this for point to point communication of speeds and setpoints

Thanks
