2 Introduction
The main concept of the DriveServer can be compared with a printer driver:
A printer driver provides all special data required for a specific printer. Every Window conform and
printable program uses a standardised interface to set up the printer. The dialog box is called “Printer
properties”. Although the interface is standardised, the parameters can be set for a specific printer.
The DriveServer also provides a standardised interface to enable access to the drives via different
fieldbus systems.
2.1 Structure of the DriveServer system
The following figure shows the basic components of the DriveServer system:

drives In the center you can see the driveswhich are addressed by several PC programs, for instance visualisation and
parameter setting programs.
fieldbuses, The drives are connected through different fieldbuses,which require different drivers.
Bus server Drivers are fieldbus-specific OPC servers with DRIVECOM-DriveServer profile as offered by manufacturers of
fieldbus cards. These OPC servers, called Bus server provide all information required for different bus systems.
Since they are not especially configured for drive systems, a configuration without the DriveServer would be very
complicated.
DriveServer The DriveServer itself does not have any special fieldbus features. It has however been written for Lenze drive
technology and is therefore able to carry out many configuration tasks without manual support from the user.
Software tool OPC clients for communication with the DriveServer can be any Software tool that has an OPC interface, e.g.
visualisation, diagnostics and parameter setting programs.
More functions of the DriveServer
DCOM Because of the use of the Windows technology DCOM, the DriveServer can overcome computer limits via
Ethernet. The software tools used do therefore not have to be installed on the computer, but can also be included
in the fieldbus module. In a local network, access is possible from any station connected.
LECOM/
System bus
Furthermore, the DriveServer is delivered with the bus servers for LECOM and system bus, since these two
fieldbus systems are mainly used with Lenze drives.
An overview of more bus servers also offered by Lenze and other manufacturers, can be obtained from the
Appendix. They have been optimised for use with DriveServer to reduce configuration tasks.
