hallo 

I can use the function 

BUT

I do not understand where I have to define the Group name. (of course, it do not match the User Administration data, and I get always the text : PLC User)

(TIA PORTAL V15.1 and TP900)

Thanks

Split from Display User Group Name.

Hello daercole,

GetUserName reads the name of the currently logged in user. "PLC User" is an user that is created automatically - even though it is strange that you get this name when no other user is logged in. At the moment I have no idea, when resp. why "PLC User" is logged in.

Mostly this function is called with a scheduled task and the trigger <user change>.

Regards,

Frink
