_Users
Users may have a name, an identification number, a password and an access code as user characteristics. Depending on the rights (authorization) the users may visualize or additionally acknowledge alerts.
Users having the necessary authorization level may also configure the control system. The characteristics of users are saved in a unique internal data point _Users. The element Deleted_Users of the data point type _Users contains the permanently deactivated users. The _Users data point is read-only for all users.
The _auth config
All data points of the data point type _Users contain the _auth config. The data points of the data point type _Users can only be set via the command channel. The WinCCOA_path/scripts/pvss_scripts.lst. file contains the commandChannel.ctl. The commandChannel.ctl script is started together with the pvss_scripts.lst when a project is started.
We do not recommend changing the _Users data point. This can lead to problems with the WinCC OA User Management. If this is, however, necessary, the Control manager running the "commandChannel.ctl" script must be stopped. By default, the Control manager with the number 1 starts the "commandChannel.ctl" script. For more information on the command channel, see chapter Command Channel.
If the authentication via Kerberos is used and the user root is disabled, CTRL cannot be started. In this case, start the CTRL manager as Windows user: -user <OS-User>.
