Property-to-property binding
Property-to-property binding binds the property of one graphic element to the same property of another graphic element on the screen. If the graphic elements display a value in different formats, the graphic elements show the same value on the HMI device. This example depicts binding the value property of a numeric display to the Level property of a mixer to show the level graphically and numerically on the HMI device.
