A box contains seven bottles of juice. In a plant, bottles are placed on a conveyor belt that keeps moving by a motor. There is a proximity sensor fixed on top of the conveyor belt to sense the bottles.

The complete system can be manually started, stopped, and reset at any moment. Once the system is started, the conveyor motor keeps running. After 5 seconds of counting the seventh bottle of juice, the conveyor motor automatically stops. At the end, the number of counted bottles is added to the running time and the result is displayed on a screen.

Note: stopping the system means de-energizing it without resetting its values. Once the system is started after stopping it, the operation of the system should continue from the stopping point.

• Task 1 ( /2): List all the required inputs, outputs, and blocks.

• Task 3 ( /4): Using PLC Fiddle, implement the Ladder Diagram program of the system. Include your program link (URL) and a screenshot of it.
• Task 4 ( /4): Using your own words, describe the implemented Ladder Diagram program of the system.
