800xa OPC DA Third party instrument
We are trying to get data from a Particle Counter (Particle Measuring Systems - Airnet II 510).
We added a generic OPC in 800xA, configured the service group, and we were able to upload the OPC Structure from the instrument. But we can not read any data.
On the same node we installed MobileOPCExplorer from Matrikon and we can read the values.
As this is not a Windows System there is no user to be configured on the other side.
Can you help us with this?
Thank you in advance.
Sounds interesting... and a problem probably tied to access permissions. If you enable Security Audit (Failures) in Local Security Policy, do you see any failures, eg failed callbacks from the OPC server?
I believe it is a matter of COM/DCOM access permission; The OPC server must be able to post asynchronous "OnDataChange" callbacks to the AdvDsOpcConnector.exe.
If you have a case registered and escalated to the SE L3 center I'm working at we could perhaps setup a remote session and let R&D participate?
A tunneller might be a workaround?
