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.

Latches and Flip Flop

Just like logic gates, the latches and flip-flops are the important elements of an electronic circuit. The logic gates form the important part of combinatorial circuits, while the latches and flip-flops form the essential part of a sequential circuit. Sequential circuits form the important concept of automata theory in electronics and electrical engineering, these circuits are a kind of logic circuit whose output depends on both present input and past inputs, that is, the input history.
