I ended up getting this error (on the ProPlus) after I started to shut down the database server from Database Administration but I aborted it. Basically, I clicked shut down, then it replied that there are connections still open. Instead of closing the connections and proceeding with the shutdown, I decided to continue working in control studio for a while. OPCWatchit gave this error until I rebooted the proplus.

I see you have several OPC threads, but all related. Based on your other threads, can I assume you are no longer getting the 80070005 error when connecting an OPC client to the local OPC server on the app station?

If remote access of the OPC client to the OPC server works, then the failure of the local OPC client would indicate that the interactive user is not logged into DeltaV when the client connects to the OPC server.

Hi Yousset. Thank you for your feedback.

For questions 1. and 2., I don't have any problems. I can access each OPC server remotely without any problems.

Questions:

1. Can you use OPCWatchit from the ProPlus to access the OPC Server on the App station?

2. Vice versa? Can you use OpcWatchit on the App station to acces the ProPlus OPC Server?

When connecting an OPC client to a DeltaV OPC Server from the Interactive Windows Logon, the DeltaV OPC server checks to see if the user is logged in to the DeltaV Application. In other words you will not be able to use a local OPC client to a DeltaV OPC server *interactively* without first logging into DeltaV. If the Local OPC client is run as a service, (or if the OPC client is remote), this is not a concern.

By the way, 80070005 is the ubiqitous error code for "Acess Denied".
