Traffic Light System Construct a PLC program for a traffic light system with the following condition: The green light will be ON for 10 second, followed by the yellow light for 3 second and red light for 20. The system will run continuously until the START/STOP switch is deactivated. Figure 12: The traffic light system Two Directional Control of Traffic Light Extend the PLC program for the traffic light system with the following condition:. Red = north/south Green = north/south Amber = north/south Green = east/west Amber = east/west Red = east/west -25 s ·5 s 25 s 5 s
