Ladder Logic is a graphical based industrial programming language used to program and configure Programmable Logic Controllers, or PLC’s. Ladder programs consist of rungs that house instructions. Once compiled and downloaded to a PLC the ladder program is scanned like a book; from top-to-bottom, left-to-right.

Feb 9, 2015 · Ladder logic was designed to have the same look and feel as electrical ladder diagrams, but with ladder logic, the physical contacts and coils are replaced with memory bits. Let’s take a look. For this program, the relay logic’s ladder diagram is duplicated with ladder logic; no more hard-wired logic, but memory locations instead.
Ladder logic has evolved into a programming language that represents a program by a graphical diagram based on the circuit diagrams of relay logic hardware. Ladder logic is used to develop software for programmable logic controllers (PLCs) used in industrial control applications.
