General information
1 About this M anual
Version 4.3 and higher of the Global Drive Control (GDC) parameter setting software include an
integrated OPC interface (OLE for Process Control) that allows access as an OPC client to bus
servers supported by the Lenze DriveServer.
ThisManual complements the “Global Drive Control –Getting Started” documentation and provides
information about the use of GDC as an OPC client.
Tip!
The DriveServer delivery package includes bus servers for the fieldbus systems LECOM and
System bus (CAN). A bus server for the MPI bus (bus server S7-MPI) is also available from Lenze.
For an overview of the bus servers supplied by Lenze and third party manufacturers, please refer
to the “ DriveServer – Accessories” documentation.

2 Configuring GDC as an OPC client
Tip!
Before configuring GDC as an OPC client, the appropriate bus server must be configured so that
it is available for selection in GDC.
• For details about configuring the bus server, please refer to the bus server documentation.
To enable GDC to communicate with the DriveServer via the OPC interface, the GDC
communication parameters have to be configured accordingly:
1. Select OptionsWCommunication... to open the dialog box Select communication driver:
General information
– All communication drivers available are displayed in the list box.
2. Select the entry OPC in the list box and click the button Parameter... to open the dialog box
OPC :
3. Enter the name of the computer on which the bus server is installed in the input field
Computer name .
– Click the button Network to select the corresponding computer from your network
environment.
– If the bus server is installed on the same computer as GDC, you can simply leave the input
field Computer name blank.

General information
Tip!
When accessing a bus server via a network, please bear in mind:
In order to protect a computer from unauthorised access, the default DCOM safety settings do not
allow OPC access.
• Check the DCOM settings for the bus server concerned and change them, if necessary. For
details, please refer to the “DriveServer – Getting Started” documentation.
4. Click the button Refresh to update the list of available OPC servers.
Tip!
The program distinguishes between “normal” OPC servers and OPC bus servers:
• Configuring OPC servers (Data Access 2.0) is usually a difficult and time-consuming process.
• OPC bus servers (DRIVECOM) have been optimised for use with GDC/DriveServer and
therefore require only minimum configuration.
We therefore recommend the use of OPC servers that also display bus server features (presetting
OPC options:
æ Bus server (DRIVECOM ) ).
5. Select the corresponding OPC server from the list field Available OPC servers and close the
dialog box OPC by clicking Ok.
6. Close the dialog box Select communication driver by clicking Ok.
Configuration of GDC as an OPC client is now complete.

3 Searching for OPC drives
Once GDChas been configured as an OPC client, you c an search online to find the drives connected
to the OPC bus server:
1. If GDC is still in offline mode, c lick OptionsWOnline or press function key <F4>to change to
online mode.
2. Select DriveWSearch... or press function key <F2> to open the dialog box Find OPC d r ives:
General information
3. Click the button Search to start searching or c lick Cancel to abort.
Tip!
• The drive controllers found on the bus are listed in the window “Drives connected to bus” .
• GDC automatically tries to allocate device descriptions to the drive controllers found.
– If only one drive was found and a device description could be allocated, the device
description is loaded immediately.
– If automatic allocation of the device description for a drive fails, the device description for
the drive can be allocated manually.
Selectthecorrespondingdriveinthewindow“Drives connected to bus” or click Drive
WChoose... in offline mode to open the dialog box for manual allocation.
• Use the command DriveWCommunication parameters... to display the OPC access path
for the active drive in the dialog box Active drive in the text field Access path (e. g .
“COM1.Device_01“ ).
• For more information about operating GDC, please refer to the “Global Drive Control –
Getting Started” documentation or the GDC Online Help.

4 Using the S7-MPI bus server
In conjunction with the bus server S7-MPI, GDC can also be used to set the parameters for drive
controllers networked via PROFIBUS DP and controlled via a Siemens SIMATIC S7 PLC.
The figure below shows the architecture of such a system:

• The GDC oscilloscope function is the only function that is not available via this
communication path.
