6.5 Integrating clients that do not support DCOM
The MK8000 server uses DCOM (Distributed Component Object Model) to
communicate via network for distributed configurations. In the event that your OPC
client does not have DCOM capability, you can install this script on the client PC to
create the illusion that the OPC server resides on the OPC client, and permits them to
communicate effectively.
This section explains how to install, customise, and remove the
TransparentOPC.reg file on an OPC client.
Using the DCOM Transparency capability
 Prior to installing the TransparentOPC.reg file, the OPC client and server PCs must
recognise each other on the network. To check this, use the ping command in the
DOS window: ping Remote Computer Name
 The TransparentOPC.reg file is compatible with the MK8000 OPC Server.
Installing the file
To install the TransparentOPC.reg file, do the following:
1. Locate the TransparentOPC.reg file (select MK8000 Installation dir > Utilities >
OPC Transparency).
2. Copy the TransparentOPC.reg file to the OPC client PC.
3. Open the TransparentOPC.reg file with Notepad (right-click Menu > Open with >
Notepad)
4. Replace the text: <insert here computer IP address or name> with the name of the
computer where the MK8000 server is installed.
Note: Don’t delete the quotes.
Insert the name of the OPC Server
5. Save and Close the file.
6. Double-click the file to register it. (Save as a .REG file in the registry.)
