Hi _paulg_,

WinCC Unified is designed as a multi-client system. This means that several clients can connect to a runtime system and each client uses its own session. It is therefore possible for several users to be connected.

This results in "@UserName" being a local system tag of the current session and as a local tag it cannot be used in a scheduled task as these are run in a global scope. So you need to use the tag in a script placed somewhere on a screen object - preferably one that is always active.

Kind regards
Stefan

Hello _paulg_

If you use a global Screen hierarchie like a startscreen with only screen windows in which you show navigation , header, content and so on, you can use a dummy object (not visible) like an IO Field (or also a visible one or a Text Field) and here use a Script like this:

Or you use the @UserName direclty on an IO Field:

But It has to run in the Screen context
