Property to property binding in an Add-On Graphic

This example depicts property to property binding within the definition of an Add-On Graphic. Property to property binding binds the property of one graphic element to another graphic element in the definition. Even if the graphic elements display a value in different formats, the graphic elements show the same value on the HMI device. In this example, a user-defined data property exists for the level of a mixer graphic element in the definition of an Add-On Graphic. Binding the property of the numeric display to the Level property of the mixer then shows the level graphically on the mixer, and numerically on a numeric display.
