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
