Prerequisites

Verify Communication

Communication between the OPC server and an OPC client must be verified. Some OPC Server vendors like Kepware and Rockwell Automation provide OPC clients with their servers. These clients can be used to validate in the same way as the client described below.

If an OPC client is not provided with the server, XLReporter provides an independent OPC client to verify connectivity and data retrieval from any OPC DA server. This client can be downloaded from www.SmartSights.com.

To run, double-click SampleClientDA.exe.

To connect to an OPC server, select Edit, New Server Connection to open the Server Properties window.

If the client does not respond as described contact the OPC DA Server vendor technical support to troubleshoot and resolve the issues.
