What is Ladder Logic?

Ladder logic is a programming language that represents a program as a series of rungs on a ladder. Each rung represents a logical condition, and the program executes by evaluating these conditions in sequence. It is commonly used in Programmable Logic Controllers (PLCs) for industrial automation to control machinery and processes. Ladder logic is characterized by its graphical representation using symbols that resemble relay circuits, making it easily understood by electricians and engineers familiar with traditional relay-based control systems.
