The circuit shown in Figure 1b is termed a ladder diagram. Figure 1 – Ways of drawing the same electrical circuit. With such a diagram the power supply for the circuits is always shown as two vertical lines with the rest of the circuit as horizontal lines. The power lines, or rails as they are often termed, are like the vertical sides of a ...
Ladder diagrams (sometimes called "ladder logic") are a type of electrical notation and symbology frequently used to illustrate how electromechanical switches and relays are interconnected. The two vertical lines are called "rails" and attach to opposite poles of a power supply, usually 120 volts AC.

Ladder diagram examples and solutions to simple PLC logic functions. These are all basic PLC functions implemented in ladder logic. Simple Start/Stop Ladder Logic Relay
A work piece must travel back and forth on a conveyor. The location of the work piece is determined by two limit switches. When the location is detected control signal are sent to a reversing motor contactor. The machine is started and stopped from a local set of push button switches. Develop a ladder logic diagram to implement this control.
In our example, we do not have an input representing movement on the conveyor belt. This would be like a proximity sensor on a sprocket or an encoder on the conveyor shaft. We will accomplish this by using a system timed bit. (100ms interval) When the conveyor belt runs, we will trigger our shift register every 100ms.
