    Overview of Ladder Diagrams

    Posted by Padhu Edupuganti on July 20, 2020 at 9:14 am

    Ladder Diagram (LD) is the most commonly used PLC programming language, which is the method that the user uses to communicate information to the PLC.

    A ladder diagram is a diagram used to represent relay ladder logic control systems.

    The diagram receives its name from the fact that it looks like a ladder because the power feed and return buses look like the vertical supports of the ladder and the series and parallel circuits connected across the power lines look like the horizontal rungs of the ladder.

    These diagrams are industry standard and are popular with those who prefer to define control actions in terms of relay contacts and coils.
