IEC 61131-1

IEC 61131-1 is an international standard that defines the basic framework for programming industrial control systems, such as those used in manufacturing and automation. It establishes common concepts, terminology, and structure to ensure consistency and compatibility across different devices and software. Essentially, it provides a blueprint for designing, developing, and managing automation programs, making it easier for engineers to create reliable and maintainable control systems. This standard helps improve communication, reduces errors, and supports integration within complex industrial environments.
