The system will be controlled by five pushbutton switches, SWITCH 1, SWITCH2, SWITCH3, SWITCH4 and SWITCH5. These switches will control the lighting and the door access in a room based on the following criteria: 1. Any o f two of the switches SWITCH1 or SWITCH2 if turned ON can turn the lighting ON, but all two switches must be O FF before the lighting will turn OFF. 2. The third switch SWITCH3 is a Master Control Switch. If this switch is in ON position, the lights will be OFF and none o f the other two switches have any control. 3. SWITCH4 when turn ON can OFF the magnetic lock at the door after 5 seconds and the door can be opened after that. 4. SWITCH5 must be in OFF position before the door can be opened. Design the wiring diagram for the controller connections, assign the inputs and outputs and develop the ladder diagram to accomplish the task.
