Write a program to implement the process illustrated in the figure below. The sequence of operation is to be as follows: Normally open start and normally closed stop pushbuttons are used to start and stop the process. When the start button is pressed, solenoid A energizes to start filling the tank. As the tank fills, the empty level sensor switch closes. When the tank is full, the full level sensor switch closes. Solenoid A is de-energized. The agitate-motor starts automatically and runs for 3 min to mix the liquid. When the agitate-motor stops, solenoid B is energized to empty the tank. When the tank is completely empty, the empty sensor switch opens to de-energize solenoid B. The start button is pressed to repeat the sequence. Put a counter which shows how many times the system is restarting
