UaGateway connects to DA-Server, but no items are found
Posted: 11 Sep 2015, 13:45
Hello.
We are evaluating UaGateway to provide UA-Clients a possibility to connect to an existing DA-Server.
The used OPC DA Server is the 'Saia-Burgess Controls AG & Merz OPC server', version 2.02.17.20 ( https://www.sbc-support.com/de/software/opc-server/ ).
The OPC Server is running and registered, ordinary DA-Clients (like the matrikon opc client) can successfully connect to the DA-Server, browse its items, add them and see the actual data from the PLC.
So we have installed the Unified Automation UaGateway, created the certificates and then started the configuration screen. We were able to successfully add the local DA-Server (showed up under the 'local' node). The UaGateway can successfully connect to the DA-Server (see attached screenshot).
Next, we started the Unified Automation UaExpert. In UaExpert we added the UaGateway Server and established a connection to it. If we then look at the 'Address Space' window we see below the 'Objects' node an entry for the 'Merz.OPC_SAIA_S-BUS.1.' server, but no items are shown.
We would be glad for any hints what could be wrong.
Notes:
- Its running on Windows 7 prof. 64bit.
- UaGateway is registered to run as auser with Administrative privileges, UAC is disabled.
- When I Stop Ua-Gateway, and then start it again, I see in ProcessExplorer that an instance of the corresponding DA-Server gets started (SBCSBus.exe and SCommDrv52.exe).
- Attached is a trace-file of the UA-Gateway.
