Prerequisites

Permissions

For any OPC DA client, including XLReporter, to browse tags and read data, the Guest account must have Browse and Read permissions to the item(s) in the database you wish to make accessible.

  1. In ViewX, on the Database tab at the bottom, right click the root branch of the tree (the System Name) and select Configure, Edit Security.

  2. Make sure that either the Guest account or Everyone has at least Read and Browse permissions checked.

Verify Communication

Communication between the OPC server and an OPC client must be verified. 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.

  1. To run, double-click SampleClientDA.exe.

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

All of the selected tags appear along with their real time values, type, quality, and timestamp.

If the client does not respond as described, contact Schneider Electric technical support to troubleshoot and correct these issues.
