VNC server closed remotely

Hi community!

I am trying to connect to the X20 PLC VNC server via VNC viewer and I get a message from the viewer that the connection has been closed remotely all the time.

The simulation is activated PLC program is running; I can ping the IF2 ethernet port, check that the default port (5900) is well set and free in both ends. Also, I have tried different ports and still not be able to get access. Still getting the same message. I tested different VNC viewers (tiggerVNC, RealVNC, anyViewer…) and same issue in all of them.

Is there a way to confirm that the ARsim and VNC server is running other that the RUN in the taskbar?

I think the configuration of the VNC server is right (see image below)

Thanks in advance for your help :slight_smile:

See following post:
VNC Viewer working with ARSim - Ask Questions - B&R Community

very likely problem will be related color depth of the VNC-client. As it is mentioned in Corne post.

Thanks for your answers.

It’s very strange. I’ve been working on the project without any problems, and suddenly I couldn’t use the viewer when trying to simulate. Now, the only VNC client I can use is the B&R VNC viewer.

By the way, I can use that viewer without any problems. I just wanted to have everything set up properly in case I run into any configuration issues. But if I have to use the B&R VNC viewer from now on, is there a way to avoid the 60-minute trial mode limitation? Can I use my AS license in the application to have the “normal” version?

B&R VNC server does not limit access to the B&R VNC client. I think the reason why the B&R VNC client works and the other one does not is due to different settings on the VNC client side, such as color depth settings.

What about the trial mode in the B&R VNC viewer? is it possible to upgrade?

See Installer Readme.txt

Note: The B&R VNC Viewer runs only on B&R PCs with installed B&R
ADI driver! On other PCs the viewer is closed after 60 minute
