Ladder Logic

Ladder Logic is a graphical programming language used primarily for programming Programmable Logic Controllers (PLCs) in industrial automation and control systems. It mimics the appearance of electrical relay logic diagrams, using rungs with contacts (inputs) and coils (outputs) to represent logic operations. It is widely used in manufacturing, robotics, and process control to automate machinery and processes.

Also known as: Ladder Diagram, LD, Ladder Programming, Relay Ladder Logic, PLC Ladder
🧊Why learn Ladder Logic?

Developers should learn Ladder Logic when working in industrial automation, manufacturing, or control systems engineering, as it is the standard language for programming PLCs. It is essential for creating logic to control machinery, sensors, and actuators in real-time applications, such as assembly lines, HVAC systems, or water treatment plants, due to its simplicity and direct mapping to electrical circuits.
