You have created and animated status LEDs using the graphic object "circle". The red LED
flashes in the initial state.

value of the tag "ON_OFF_Switch" is set to "1" and the green LED flashes.
● When the control program is stopped by pressing the "Machine ON/OFF" button again,
the bit value of the tag "ON_OFF_Switch" is set to "0" and the red LED flashes.
In the next section you will create the graphic object "Conveyor".
