No alarm indication on button controls

FAQ Question
I’m using a button control to refer to a subpicture (diagram), but I don’t get any alarm indication on the button, how can I solve that?

Answer

In order to get the alarm indication on the button, you must place a Rectangular Field on top of the command button with a reference to the same diagram. The rectangular field will then blink with the alarm colour, if there’s an alarm on the referenced diagram.
