Custom PLC Languages
Custom PLC (Programmable Logic Controller) languages are proprietary or specialized programming languages designed for industrial automation and control systems, often based on the IEC 61131-3 standard. They are used to program PLCs, which are ruggedized computers that automate electromechanical processes in manufacturing, energy, and infrastructure. These languages typically include ladder logic, structured text, function block diagrams, and sequential function charts, tailored for real-time control and reliability.
Developers should learn custom PLC languages when working in industrial automation, robotics, or process control industries, as they are essential for programming PLCs to manage machinery, assembly lines, or safety systems. They are used in scenarios requiring deterministic, real-time responses, such as automotive manufacturing, water treatment plants, or power grid management, where standard programming languages may not meet hardware or safety requirements.
