Given four normally open pushbutton switches (A, B, C, and D). The motor will turn on a motor if pushbuttons A and B are closed, or if C is open and D are closed? Write a PLC program and explain? In an application, a relay is used to turn on a solenoid valve to release water in a fluid tank. A push button switch (start button) is used to activate the relay. If the relay is not activated, a pilot light (red) indicator will come on, otherwise the solenoid valve and a pilot light (green) will come on. Write a PLC program and explain? Consider an application controlling a motor by inputs consisting of two pressure switches (Low/High), one photodiode switch, and a pushbutton switch (stop button). The motor is in off state if the high pressure switch or stop button are not activated, otherwise it will come on if the start button and photodiode are activated? Write a PLC program and explain? In a steam boiler two pressure switches. (Low/High) are used. The low pressure switch activates when the steam pressure goes below 80 psi, and the high pressure activates when the pressure goes above 125 psi. The output is monitored by three bulbs (yellow, green, red). The green lamp indicates the pressure is between 80 psi and 125 psi, yellow lamp indicates pressure is below 80 psi, and red indicates the pressure is above 125 psi. Write a PLC program and explain? Consider an application consisting of three inputs consisting of normally open toggle switches (A, B, and C) and two outputs (X, and Y). Write a ladder logic program for each of the following: 1) when input A is dosed, turn ON and hold ON outputs X and Y until A opens, 2) When input A is closed and either input B or C is open, turn ON output Y; otherwise. it should be OFF. 3) when input A is closed or open, turn ON output Y, and 4) when input A is closed, turn ON output X and turn OFF output Y? Write a PLC program to describe an application consisting of mixing two fluids in a tank? Describe function of the program along with the inputs and outputs considered for the application? Write a PLC program to describe an application consisting of keeping constant the level of fluid in fluid tank - if the level goes below a minimum, the fluid enters into the tank, and if the level goes above a maximum, inlet stops. Describe function of the program along with the inputs and outputs considered for the application
