Programming Examples
In LED Separation mode, the LEDs in the corner of each momentary pushbutton
may be directly controlled by the PLC program. The example on the right shows a
segment of a program that lights button 2’s inset LED when input X7 is energized.
In
order for this example to work, the panel must be configured for LED separation and
button 2 must be a momentary pushbutton.
