I’m trying to use FactorySQL to retrieve data from a local KEPServer-EX OPC server. In the Frontend when I try to expand the OPC server tree to see the items configured in the OPC server I get the error message “Browse failed with message: Cannot connect to OPC server for browse”.
I can solve problem by configuring the FactorySQL service to run as “Local System” but I really need it to run under another account to facilitate communication with another OPC server (DeltaV).
Please tell me how to resolve this issue. If this is a permission issue, can you tell me which permissions are required to browse the OPC server?
