Has anyone set up an OPC-UA connection to connect to a Cognex OPC server? Cognex documentation is limited and doesn’t give me enough information about ports to get this working. I obviously tried the default that Ignition gives with no luck. Any help would be appreciated. I can set up the connection with KepServer EX, but am migrating.
