Hi all,
I have an issue in the communication between PI Server and OPC Server.
After many test we have found this trouble occurs each time OPC Server Machine is restarted. Because the user and password configuration in OPC DCOM is missing and communication fail(all tags become Timeout state).
To fix temporaly the problem we have to execute dcomcnfg.exe windows tool, navigate to Component Services | Computers| My PC | DCOM Configuration and search OPC DCOM item. (Right Click), click on Identity tab and fill user,password and confirm password in this user radio button. Yoy can see details in the snapshot attached below. It looks as whether all user and password configuration parameters disappear when OPC Server reboot.
With this solution communication is restablihed until an inesperate or controllated reboot happens.
Could you please help me?
Thanks in advance
