WinCC OA users in Linux ...

[equesada]

Hello,
I wonder what user is required for a project in Linux. Installation is performed as "root", but have not seen documented in the help if needed another user for the runtime of the projects. By other hand, just as "root" I can start the project. With another user can not get the detection of USB dongle key .

Best regards,

Eugenio

Hello,

it should be possible to start the project also with another user.
If you are using a dongle please have a look at the following chapter of the online-help, there it is described what has to be configured:
Installation - Requirements for WinCC OA --> Licensing.

I am not sure about the Dongle key, but here are some items that I discovered running as NON-root

Use Dolphin and change the permissions for the following folders:
/etc/opt/pvss
/opt/WinCC_OA/3.11/log
Right click on folder and change properties->permissions->can view & modify content for everyone and check the box for “Apply changes to all subfolders and their contents”
Projects should be user independent. It is suggested that you put your projects in the following folder (which needs to be created). Be careful, sometimes the /opt folder is on a small partition. Be sure you have enough space for your project!
/opt/WinCC_OA_Proj
Be sure to change the permissions and make it shared. The sharing is important as this is how redundancy and distribution work.

Note: changing the mode of /etc/opt/pvss and /opt/WinCC_OA/3.11/log is already done by the rpm installation and therefore should not be needed
