Desktop UI With CentOS

[uxout]

Hello,

I'm trying to connect a DesktopUI under CentOS 7 to my WinCCOA 3.15 project running on Windows 10 Host.
I can connect to the same project with Android and Windows Desktop UI Client, but I'm having issue with CentOS Desktop UI Client.
This is what I get :

Code: Select all

Cannot register project: PA_E_REG_ERROR
: installdir: /root/.wincc_oa-cache
Initialization via HTTP server failed

Can someone explain me why I'm having this error and how to resolve it?

Thanks.

Hello,

Take a look at /root/.wincc_oa-cache to see if the project files were created there. If yes, also look at the generated config file on this client at the cache directory to see if it is somehow corrupted.

The projects are getting registered in the file /opt/WinCC_OA/DesktopUI/pvssInst.conf
Check if this file exists and has permissions for the user running the desktop ui.
It should also contain at least 2 lines like:

Code: Select all

[Software\\ETM\\PVSS II\\3.15]
InstallationDir = "/opt/WinCC_OA/3.15"

I just tried to connect to Demo ETM WinCC OA project and the directory WinCCOA_Demo is correctly created in /root/.wincc_oa-cache, but there is only config files downloaded.
Here is the config file :

The config seems correct to me.
Have you tried to connect Unix WinCC OA Desktop Client to this project?

[uxout]

There is no file /opt/WinCC_OA/DesktopUI/pvssInst.conf
Isn't this file created when you install the whole WinCC OA Software instead of the WinCC OA Desktop Client?

[mkoller]

Check something like this:
rpm -qp --scripts /opt/WinCC_OA/3.15/data/clsetup/linux-rhel-x86_64/WinCC_OA_3.15-desktop-ui-rhel-0-7.x86_64.rpm

this shall show you a small script which creates the registry file, e.g.
...
PrepRegistryConfig()
{
CONFIG_STD=pvssInst.conf
REGDIR_STD=/opt/WinCC_OA/DesktopUI
...

so this file should be created during the installation of the WinCC_OA_3.15-desktop-ui rpm package

[uxout]

Yes, i got what you get.
Does that mean that the Unix Desktop Client is not correctly installed?

[mkoller]

It seems so. Try deinstalling the package and reinstall it and check if there are any errors while installing, then check after the install if the pvssInst.conf file exists.

[uxout]

Alright, it works now.
Thanks for your help !
