Question

Design a circuit, utilizing set/reset coils where PB1 or PB2 start Motor M1, PB3 or PB4 start M2 and PB5 turns off all motors.

Answer 1

in this ladder logic, motor 1 will be on when any one of the push button is pressed PB1 or PB2 as it is connected in parallel. Again M1 is latched therefore, it will be on even push button are released. Similarly for motor 2. Now push button 5 is connected in normally closed Fashion, if it is pressed it will deactivate both motor simultaneously.

Note- please find me in comment box if you find any difficulty. I assume this is a plc question. Good luck
