Ladder Logic is a graphical programming language used to develop software for programmable logic controllers (PLCs). It represents electrical control circuits through symbolic diagrams resembling physical relay logic schematics, facilitating the design and troubleshooting of industrial control systems.

About Ladder Logic
Ladder Logic was developed in the late 1960s as a method to simplify the programming of PLCs. It was created to mimic the schematic diagrams of relay logic hardware, making it easier for engineers and technicians familiar with traditional relay control systems to transition to digital control systems. The language allowed for more efficient and flexible automation in industrial processes.
Strengths of Ladder Logic include its simplicity, ease of understanding for those familiar with electrical schematics, and suitability for discrete control tasks. Weaknesses involve limited scalability, difficulty in handling complex algorithms, and less efficiency for analog process control. Competitors include Structured Text (ST), Function Block Diagram (FBD), Sequential Function Chart (SFC), and Instruction List (IL).
