H.W: Write a program to implement the process illustrated in figure below. The sequence of operating 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 energized 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-energized solenoid B. • The start button is pressed to repeat the sequence. SOL A Empty sensor switch Motor -SOL B Start/stop control station Full sensor switch

The process shown in Figure 1 is to be used to control the level of water in a storage tank by turning a discharge pump on or off. The modes of operation for which programming is required are as follows: Pump running Low level High level ON/OFF High sensor switch MANAUTO Low sensor switch Pump motor Figure 1: The process used to control the level of water in the storage tank OFF Position -The water pump will stop if it is running and will not start if it is stopped. Manual Mode -The pump will start if the water in the tank is at any level except low. Automatic Mode -If the level of water in the tank reaches a high point, the water pump will start so that water can be removed from the tank, thus lowering the level. When the water level reaches a low point, the pump will stop. Status Indicating Lights -Water pump running light (green) - Low water level status light (red) - High water level status light (yellow) Provide the allocation list and the ladder logic program for the above…
Consider a manual washing machine with five (5) buttons: WASH, RINSE, SPIN, STOP and PAUSE. Press any of these buttons will change the state of the washing machine. Without any interruption, wash, rinse and spin process will take 15 minutes each to complete the process and then stop. Button WASH transfer the washing machine state from stop to washing state. At washing state, it will change to rinse state if button RINSE is pressed, spin state if button SPIN is pressed or pause state if button PAUSE is pressed. If the machine at any state (wash/rinse/spin/pause), the machine will stop if button STOP is pressed. Nothing will happen if the same button is pressed while the process still going on. For example, press WASH button while the machine is at washing state will not change the state. Based on the above description, the states, inputs and outputs are as follow: State Inputs Outputs So: Stop a: WASH button 0: Nothing happen Sı: Wash b: RINSE button 1: Process S2: Rinse c: SPIN button…
