Great, I am glad that it works!
Thank you for update.

Hello,

I agree with you. I also have encountered a need to configure DCOM locally in some situations - when the server was running under a service account (not sure if this is the case with FactoryTalk), but still, our client is behaving differently from other vendors, in this case.

I hope the suggested steps will resolve the issue for you too.

Best regards

Hello,

I was able to resolve the issue by configuring DCOM - more or less the same as described here: support.softwaretoolbox.com/app/answers/detail/a_id/1379/~/i...-opc-server-and-i-get-an-error .

Specifically, here is what I did:

1. Started DCOMCNFG.
2. Right-click on Console Root -> Component Services -> Computers -> My Computer, select Properties.
3.1. On the COM Security, press Access Permissions -> Edit Limits
3.2. In the permissions dialog, press "Add", and add "Everyone". After return to the permissions dialog, make sure at least the "Local Access" under Allow is checked, and Deny is not checked.
3.3., 3.4., 3.5.: Do the same with "Interactive", "Network" and "System".
4. Repeat steps 3.1-3.5 for Access Permissions -> Edit Default. (again, also make sure that Local... is checked under Allow)
5. Repeat steps 3.1-3.5 for Launch and Activation Permissions -> Edit Limits. (again, also make sure that Local... is checked under Allow)
6. Repeat steps 3.1-3.5 for Launch and Activation Permissions -> Edit Default. (again, also make sure that Local... is checked under Allow)
7. Press OK on the "My Computer Properties" dialog.

I hope this helps

Hello,
thank you for perfect instructions! I was able to configure the FactoryTalk as needed. I can see OPC tags in OPC clients.

And, I was able to reproduce the issue you reported (HRESULT 0x80040202).
So, I can now work on it. Give me some time. I will report my findings here once I know more.

Best regards

Hello,
I think I am getting close... but not there yet.

Here is what I have at the moment:



Can you please elaborate (if possible, step by step) on "... I have added a ControlLogix Emulator to the 1789-A17 Virtual Backplane that comes with FT Gateway. This is done by right clicking the virtual backplane in the communication setup window and wiring up a shortcut to it just like you have done already." . Where precisely should I click (which of the icons is the virtual backplane?) and what to select?

Thank you

Hello,

I managed to get an entitlement and 30-day demo activation from a local Rockwell representative.
So, now I have what I think is the proper Rockwell software installed (FACTORYTALK LINX GATEWAY 6.11.00),
and I have also proceeded to create an application and a "shortcut", and have enabled the OPC DA Server.

There are now two OPC DA Servers on the machine: "FactoryTalk Gateway", and "RSOPC Gateway". Both show my shortcut name under the root of their address space as a branch, but that's all that is there. There are no OPC items (tags) to actually use for the repro.

Is that because I am missing the physical device, or because it is not enough just to create the shortcut, but I also need to do something more?

Please advise.
