Design a small PLC system that controls the east garage entrances, exits and parking capacity of university. Assume the east parking garage has a max capacity of 150 cars and that the only users that can enter and exit the garage are those with valid university IDs. Also note the parking attendant vehicles must be allowed entrance at all time even when the garage is full. however, anyone else with a valid university ID cannot enter the east garage when it is full. Draw a neat figure of ladder logic on the paper and upload an image as a answer.
