CODESYS
CODESYS is an integrated development environment (IDE) and runtime system for programming industrial automation devices, primarily programmable logic controllers (PLCs). It provides a standardized IEC 61131-3 programming environment with multiple languages like ladder logic, structured text, and function block diagrams, enabling engineers to develop, simulate, and deploy control applications across various hardware platforms from different manufacturers.
Developers should learn CODESYS when working in industrial automation, manufacturing, or embedded systems that require PLC programming, as it is widely adopted in industries like automotive, energy, and robotics for its vendor-independent approach. It is essential for creating real-time control applications, integrating with industrial networks (e.g., PROFINET, EtherCAT), and reducing development time through reusable code and simulation features.
