Hi!
The Front Panel from your Program isn't downloaded to your RT Target.
In normal execution the RT System doesn't have any User Interface.
So even if making Remote Panel Connection or during the developpement modus, the User Interface Events aren't cached in the RT System.
You can make User Events.
