Restrict utility access to PI Vision

By default, AVEVA PI Vision is configured to allow the AVEVA PI Vision Display Utility to AVEVA PI Vision Migration Utility to read and write displays. You can restrict this access by:

• Allowing the utilities to only have read access.

• Disabling utility access entirely.

To restrict utilities to allow read access:

1. Use an editor to open the web.config file in the PI Vision\<Utility> root installation folder.

2. To restrict access to only read operations, look for the following entry in the web.config file: <add key="UtilityAccess" value="ReadWrite" />

3. Update this entry to: <add key="UtilityAccess" value="Read" />

To disable utility access entirely:

4. Run Internet Information Services (IIS) Manager.

5. In the Connections pane, select Application Pools.

6. Right-click PIVisionUtilityAppPool and choose Stop.
