Can we implement CU310-PN with Sinamics S120 drives for tandom application (master-slave)?

Two Sinamics with profinet do not have direct interconnection (only Sinamics link) but it is usable only with CU320 and CBE20. For such application would be possible solution to use CU310DP and use point to point communication (Data exchange brodcast). But both devices must be a slaves under some Simatic. Because Simatics (HW configuration)control this data exchange broadcast.

Anoth solution is to use CU320 and CUA32 on the powermodules. Than you have all information inside.

But such master-slaves can be done good for spped/torque control. For position master slave (Gearing) I would recomend SImotion. Basic gearing is usable alsowith Sinamics onlybut it is not so easy!
