Design a PLC program and prepare a typical I/O connection diagram and ladder logic program for the following motor control specifications: • A motor must be started and stopped from any one of three start/stop pushbutton stations. • Each start/stop station contains one NO start pushbutton and one NC stop pushbutton. Motor OL contacts are to be hardwired.
