Ladder logic programming language is characterized by looking very similar to electrical relay circuits. Draw ladder diagrams for simple logic operations.
Ladder diagram, better known as ladder logic, is a programming language used to program plcs (programmable logic controllers).
X0, x1, x2, and x3 are the open type input contacts while y0, y1, y2, and y3 are the output contacts. The example below shows a ladder diagram with pushbuttons (pb), control relays (cr), a motor (m) and a light (l). They are called, respectively, the rails and the rungs.
