Preface and general information
The
DriveServer is a software which provides easy integration 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.
