Make an active alarm visible

Configure the
Active
 property of a graphic object to make an alarm visible at runtime. Dynamically link the
Active
 variable of the graphic object to the
Active
 variable of an alarm. At runtime, the appearance of the graphic element changes when the alarm is active.
The
Active
 variable requires no scripting or NetLogic. For example, you can create a digital alarm and then bind the
Active
 property of a graphic element, such as an LED, to the
Active
 variable of a digital or other alarm. The LED lights up at runtime when the alarm reaches its configured limits or state.
