Ladder Logic
Save
Ladder Logic is a graphical programming language used in programmable logic controllers (PLCs) to control automation systems. It is a simple yet powerful language that is easy to learn and use, making it a popular choice for industrial automation applications.
History of Ladder Logic
Ladder Logic was developed in the 1970s by engineers at General Motors. It was designed to be a user-friendly alternative to traditional electrical schematics, which could be difficult to understand and maintain. Ladder Logic's graphical representation makes it easy to visualize the flow of logic in a program, and its modular design makes it easy to add or remove elements as needed.
How Ladder Logic Works
Ladder Logic is based on the concept of Boolean logic. Boolean logic is a system of logic that uses only two values: true and false. Ladder Logic uses these two values to represent the state of inputs and outputs in a PLC program. Inputs are conditions that can be true or false, such as the presence or absence of a signal. Outputs are actions that can be performed, such as turning on or off a motor.

Ladder Logic programs are made up of a series of rungs. Each rung represents a single logical operation. A rung consists of three parts: an input section, an output section, and a logic section. The input section contains the conditions that must be met for the rung to be executed. The output section contains the actions that will be performed if the rung is executed. The logic section contains the logic that determines whether the rung will be executed.
