is it possible to use teleservice adeptor direct with cu320 control unit.?

such as PLC, then it is possible to connect "route" from the PLC and connect to the CU320 drive system (DriveES Basic is needed for that).

I never heard of the teleservice adapter being used on the network without a master, such as direct, point-to-point connection to a CU320. It does not sound impossible, but should be tested first.

Another option would be to use an Ethernet Teleservice adapter instead of a Profibus version. New CU320-2 DP controllers have a built-in Ethernet port for PG access. Older CU320 controller would need to have a Profinet CBE20 card.
