Problems communicating with VR2109


I have made a WinStudio screen in IndraWorks Engineering 15V12 that I want to have running on my VR2109. I am able to connect to it and upload the screen, but the VR2109 does not update any values.

I think the problem stems from my OPC UA certificate. I am able to generate one just fine using my computer’s Machine name and use the virtual WinStudio screen in IW15V12, but when I attempt to use the VR2109’s Machine name (“2750” in this case), I run into some problems.

Below is shown the various options for when I setup the certificate, the trusted certificate in ctrlX WORKS, and the error message I get, when testing the connection with it afterwards.

Any ideas on, what I do wrong?

For the VR2109’s Machine name, I have used its Device name, which I could see in its options menu after booting the VR2109. I have also tried changing it with an Admin.ini file on my USB key, but that did not work, either.

Thank you.

Did you already check this topic for further information? There was a discussion of how to use WinStudio and ctrlX CORE.

EDIT: And of course don't forget to accept the certificates on both sides.

The standard device name of a VR21 is "Compact". You can see it in the cockpit tool in the folder network settings. So in my opinion you just have to create a second certificate with this device name to the OPC_UA communication running with your Notebook and the VR21

I am also unable to get a Winstudio app on VR21 to communicate with the ctrlX OPC UA server, even though I can do it when running the winstudio app on my laptop. I have checked every thread on this forum concerning this matter and the pdf by Peter_B without any luck. Is it actually confimed that this is possible, and can someone provide even more detailed descriptions of how this is done?

Winstudio version: standalone from IW 15V16 installation folder

ctrlX OPC UA server: 1.16.0
