Thank you for the update. It looks like I really need to continue trying to make the repro.

Hi!

Unfortunately, no combination of those static properties changes the outcome:
            EasyDAClient.SharedParameters.ClientParameters.UseCustomSecurity = true;
            EasyDAClient.SharedParameters.ClientParameters.TurnOffActivationSecurity = true;
            EasyDAClient.SharedParameters.ClientParameters.TurnOffCallSecurity = true;

These are set before the client is instantiated and I can confirm they are set correctly before subscription.

Hello,
since I do not have a software for the repro yet, below is a suggestion I had in mind since beginning, but thought that I would try it out myself:

Can you experiment with security settings inside QuickOPC, by extending the app (in source code), as described here? www.opclabs.com/forum/connections-reconnections-com-dcom/124...ng-to-remote-machines-via-code

Best regards
==================================

A copy of the most important of the above mentioned forum thread:

Can you please try to assign different combinations to following static properties - in the code, before the very first OPC operation is attempted:
EasyDAClient.ClientParameters.UseCustomSecurity 
EasyDAClient.ClientParameters.TurnOffActivationSecurity 
EasyDAClient.ClientParameters.TurnOffCallSecurity

[ADDED LATER: TurnOffCallSecurity only has any influence when UseCustomSecurity == true.]

Hello,

I appreciate your offer ! However, the whole thing is, I need to have a reproducible scenario on our computer and be able to troubleshoot/analyze it locally, with all tools such as source code debugging we have. So no, it's practically impossible that you could do it for us.

Thank you anyway

Hello,

I have been working with Jesse as well.

If you are unable to receive an entitlement from Rockwell, I am willing to complete any testing and pass it on.

Best

Hello.

We are back where we were. I have stated already twice that the the Gateway is not in the download. I have even checked the custom installation options to make sure it was not deactivated by default - no such thing is there.

And, I cannot download using the alternative link you provided - I am not entitled to - see the images attached.

Regards

Hello,

That probably means either the FactoryTalk Gateway OPC component wasn't installed, or (more likely) the installer I linked was missing it.

compatibility.rockwellautomation.com/Pages/MultiProductFindD...ode=3&refSoft=1&versions=57679

I know, for sure, this download contains the OPC components which you should be able to install right over what you currently have working. My apologies if the earlier link didn't!

Hello,

The FactoryTalk Administration console is where you configure the application that will be bound to the OPC DA (and UA) server. There is a link in the toolbar of that application to the FactoryTalk Linx Gateway Configuration application.

The workflow is:
  1. Open the FactoryTalk Administration Console
  2. Right click Local and select New Application
  3. Create a shortcut to a device and name it]
  4. Open the FactoryTalk Linx Gateway Configuration application
  5. Select the scope to the named application created in the FactoryTalk Administration Console
  6. Apply and then OK

The OPC DA server (and UA) will now show the device(s) that were configured.

I've attached a screenshot as well.

I have run the "FactoryTalk Directory Configuration" and I think I have successfully configured the local directory.

But, I am still not sure that what you pointed me to is FactoryTalk Linx Gateway. It does not say so anywhere, as far as I can tell. Specifically, the Start menu has no "FactoryTalk Linx gateway administration tool" you mentioned. The closest name to it is "FactoryTalk Administration Console". Is that what you meant?

Also, re "you must have a device with which to communicate with" - I have no such devices. If it's not possible to reproduce the issue without a physical device, it is not reproducible by me at all. But I would expect at least the OPC server show up more or less empty, if there are no devices. But there is no OPC Classic server at all.

Regards
