Hi All, Trying to use a pac to change dlt labels when a room screen is open/closed. Having some issues with the labels, when I use the following in the pac SetStringIBSystemIO("Label Group Text", "Local", "Lighting", "Load 2", 0, 'New Label'); It changes the label to default ie Button1, Button 2 etc... When I connect pc to network and simulate the logic works fine and label changes to "New Label".... Using latest piced 4.8.1.
