PROFIBUS-DP and controlled via a Siemens SIMATIC S7 PLC.

• A bus system (MPI, Ethernet or PROFIBUS) is used to connect the PC with the DriveServer to
the PLC. The DriveServer uses the bus server S7 as OPC bus server.
• The S7 program uses special Lenze function blocks via which the DriveServer can access the
drives through the PLC as if the PLC was not connected.
• The drives are connected to the PROFIBUS master of the PLC via PROFIBUS-DP.
