Can't read Tag @UserName

Sorry but i can't read  Tag @UserName

I can see on an IO Field on HMI but i can't read Tag from a script.

For example i have to write a line on a txt every time an user is logged in.

I use Tags("@UserName").Read(); but this return 'undefined' and this error:

HmiTag: Tag '@UserName' does not exist

Split from Read out current user from Runtime.

It does not work. Seems you can not use local tags in scripts.

As @AndreaLari mentioned, the TraceViewer gives an error "Tag does not exist".

So it is not about WString or data type

Hi

There is a bug here, so you need at least Runtime V17, Update 2.

Hi

TiaPortal v18 same behaviour.

I can read @UserName form a control script.

But not from a task scheduled script.

Hi,

as someone wrote above: It is not possible to read the systemtag "@CurrentUser" in a Scheduled Task.  Please keep in mind, that with Unified we have a server/client system and you can probably have more than just one client (or even you have no Browser opened to display the RT). That's the same reason why it is also not possbile to access to "UI." from a Scheduled Task.

Greetings,
