6 First steps for the Drive Server
The DriveServer enables communication via several media. As OPC server it operates in the background
and does therefore not have its own operator surface. The surface is provided by the OPC clients which
communicate with the DriveServer.
Tip!
In general every PC program with OPC interface, – e.g. a visualisation – can be used ad OPC client
and thus access drive parameters via the DriveServer.
Before we will give you further information on the software components, the next paragraph will inform
you about how the DriveServer starts.
6.1 Starting the DriveServer
The DriveServer is started automatically when an OPC clients want to access it.
The DriveServer starts all bus server and identifies all drives by means of the addresses sent from the
bus servers.
Identification means that the DriveServer checks every address for Lenze controllers. If a Lenze
controller is indicated in the address, the DriveServer detects the parameters for the corresponding
controller.
Based on these information, the name are for the DriveServer system is created. It lists all drives and
its parameters in form of a tree. OPC clients can access this list by means of the OPC browse function..
There are two ways to access the tree.
• Hierarchical: The name area corresponds to the tree structure created by the DriveServer.
• Flat: The name area only consists of one level which includes all elements.
The following figure shows a part of a (hierarchical) tree structure for a DriveServer system with three
fieldbus systems connected: PROFIBUS-DP, CANopen and LECOM
