Experimental Procedure: You are requested to use SIMATIC S7-300 PLC to control a production line (mini mechatronics trainer) with a traffic light signal. Write a Step 7 program to control the following operations: (1) Use a push button to initiate the system and turn the conveyor on and another push button to turn the system/conveyor off, then using 3 LEDs to simulate a traffic light operation as follows: a-Turn on the green light for 5 s; while all the other lights are off. b- Turn on the yellow light for 5 s; while all the other lights are off. c- Turn on the red light for 40 s; while all the other lights are off. d- Repeat the sequence for infinite time as long as the system is ON. (2) When green turns on, eject a workpiece from the feeder magazine: the conveyor transfers it to

Please draw a ladder diagram (plc) for this question
Experimental Procedure:
You are requested to use SIMATIC S7-300 PLC to control a production line (mini
mechatronics trainer) with a traffic light signal.
Write a Step 7 program to control the following operations:
(1) Use a push button to initiate the system and turn the conveyor on and another push button to
turn the system/conveyor off, then using 3 LEDs to simulate a traffic light operation as follows:
a- Turn on the green light for 5 s; while all the other lights are off.
b- Turn on the yellow light for 5 s; while all the other lights are off.
c- Turn on the red light for 40 s; while all the other lights are off.
d- Repeat the sequence for infinite time as long as the system is ON.
(2) When green turns on, eject a workpiece from the feeder magazine; the conveyor transfers it to
the stopper, which opens the way to the container, then closes again. Eject a piece each time
green turns on.
(3) Use the inductive sensor to count the number of metal workpieces in the container.
(4) Use the capacitive sensor to count all workpieces in the container.
