Hello Yaacov_M,

there is not systemtag like "@CurrentUser" for reading out the
name of the logged in User, for reading out the name of the
Group, the User belongs.
If you would not use the option "Simatic Logon" the Users and
Groups are configured in the WinCC-configurationdatabase in the
table "PW_User", and you could read out the name of the Group,
the User belongs.
If you would use the option "Simatic Logon" only the Groups are
configured in the WinCC-configurationdatabase in the table "PW_User",
and the Users are configured in Windows.

You could try to use the SIMATIC Logon Development Kit, for
finding out the name of the Group, the User belongs.

The Development Kit is intended for programmers who wish to integrate
SIMATIC Logon in a customer application.

You will find the following files in the directory "...\SimaticLogon\developmentkit":
•SL_ProgrammingGuide.pdf
The "SL_ProgrammingGuide.pdf" contains the English language manual SIMATIC;
SIMATIC Logon Development Kit; Programming Guide.
•SL_Example.zip
The "SL_Example.zip" file contains a example application. The SIMATIC
Logon Development Kit programming guide uses an example application to
demonstrate how to integrate SIMATIC Logon in a customer application.

Regards

Georg Berghof
