Question

A simple farm milk packing system has one proximity sensor (using one of the buttons) to count the number of milk bottles, one start pushbutton, one stop pushbutton, and one reset pushbutton (using one of the switches) to reset counters. When the start button is pressed, the assembly line starts. After 5 milk bottles are detected by the proximity sensor, the packaging machine will be initiated to pack them into a box (i.e., each package/box must contain 5 bottles). Every time when 4 boxes are packed, the system has to stop automatically in order to let workers move those boxes off the assembly line. Please use PLC counters to complete the following tasks: (1) Counting 5 bottles for each box; (2) Counting 4 boxes; (3) Counting the total number of boxes filled in a day.

Write a ladder logic program needed to implement each of the following (assume inputs A, B, and C are all normally open toggle switches). A. When input A is closed, turn ON and hold ON outputs X and Y until A opens. B. When input A is closed and either input B or C is open, turn ON output Y; otherwise, it should be OFF. C. When input A is closed or open, turn On output Y. D. When input A is closed, turn On output X and turn OFF output Y.

1- Write a PLC ladder program to implement the process illustrated in Figure. 2- Indicate all the input and output field devices in their un-actuated conditions with symbolic addresses. The sequence of operation requires that: * Normally open start push button and normally closed stop push button station is used to start and stop the process. * When the process starts, the tank is empty and solenoid A energizes to start filling the tank with liquid. * As the tank fills, the Empty sensor switch closes. * When the tank is half full, the Mid-full level sensor switch closes and the motor starts running to mix the liquid. * When the tank is full, the Full level sensor switch closes momentarily so that: a- The motor stops. b- Solenoid A is de-energized. c- 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.

Design a state-based PLC program to control a motor. The system specification is as follows: Press a normally open push button, and the motor will start. The motor will stop after 5 minutes or when a normally closed push button is pressed. When the motor is running, a red light is ON. When the motor is stopped, a green light is ON. Use the Fail-Safe concept, i.e., if the wire of the stop push button is disconnected, the motor cannot be started. Complete the following: 1. Define the inputs, outputs, and states of the system described above. 2. Design this process control using state diagrams. You are required to clearly express each state of the system and describe the conditions for state transitions. 3. Create complete ladder logic for the system.
