When the start button is pressed in a control system;
1)Green light and Yellow light lamp will turn on, after 10 seconds the yellow light lamp will turn off from these lamps,
2) As soon as the Yellow Light goes out, the M1 and M2 motors will start to run for 10 seconds and stop for 5 seconds.
3) This periodic process will be repeated six (6) times (in 15 second periods).
4) 6. When finished again, M1 and M2 motors will stop completely and the green light will turn off.
5) As soon as the green light goes out, the red light will turn on and the start button will be pressed again.
6) When the start button is pressed again, the red light will turn off and the system will work as described in the first 5 items.
7) If the stop button is pressed at any time, the engine will stop completely, the red light will turn on, and all other lights will turn off. When the start is pressed again, the red light will turn off and the system will work as described in the first 5 items.
Write the PLC program using the Ladder Diagram (ladder logic) for these requests.
Before writing the program, make the PLC input and output definitions at the top. NOTE: It will be assumed that the start button is not pressed as long as the green light and the Engines are running.
