1 Preface and general information
The DriveServer is a software which provides easy i ntegra tion of drives into open automation
struc tures based o n OPC (OLE for Process Control ).
When used together with the bus server S7, you can access drives which are connected via
PROFIBUS-DP and controlled via a Siemens SIMATIC S7 PLC.
The following figure shows the architecture of such a system:

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.
