• Inputs and outputs
• Ladder logic diagram
3. Advantage and disadvantages

3. Problem statement
• Washing machine starts when we press the start button
• 5sec for water inlet
• 5sec for detergent inlet
• 10sec forward spin then alarm should on for 5sec
• Reset the process by Pressing stop button

4. INPUTS;
I0.3 = START
I0.2 = STOP
OUTPUTS;
M0.1 = MACHINE START
Q0.1 = WATER INLET
Q0.2 = DETERGENT INLET
Q0.3 = FORWARD SPIN
Q0.4 = BUZZER
Solution;

5. Ladder Logic Diagram

6. Advantages
• Allowing for precise control of water levels, agitation, spin cycles, and
detergent dispensing.
• Flexibility: PLCs are highly adaptable and can be reprogrammed
easily to accommodate different washing programs and load sizes.
Disadvantages
• High cost
• Complex programming
