18.7Configuration of the Client Computer

Overview

When operating with DCOM, this situation is that the OPC server runs on a different computer from the OPC clients (applications). This is why no process for the OPC server is visible in the Windows Task Manager of the client computer.

To allow the OPC clients to access the OPC server, the following requirements must be met for this mode:

SRegistering the OPC server

The OPC server and its location must be registered on the client computer. This registration is necessary so that the COM library knows the required object making configuration possible.

You must specify the user account will be used to access the OPC server. The procedure is described below.

SProviding “OPC proxy” libraries

The OPC Proxy libraries provided by the OPC Foundation are also required on the client computer. This library converts the COM calls into a data stream for transmission over the network.

You should also read the notes on how to install a client in the Installation Instructions.

SRegistering the OPC client

When necessary access rights and security settings must be made for the OPC clients. As shown below in the example of the OPC Scout, the default setting assumes an open system and assumes that the user will adapt the settings when higher security is required.

Make the required settings analogous to the description of configuring the server computer in Section 18.6. Below, you will find instructions on registering, for example the OPC Scout as a client .
