The International Electrotechnical Commission (IEC) published the standard IEC 61131:2024 SER on January 8, 2018. This standard is pivotal for the design and implementation of programmable controllers across various industrial sectors, ensuring reliability and consistency in automation solutions worldwide. It defines the architecture and programming languages suitable for programmable logic controller (PLC) systems, encompassing aspects such as structured text, ladder diagrams, function block diagrams, instruction lists, and sequential function charts. This comprehensive approach supports engineers in developing efficient and maintainable control applications that meet stringent industrial requirements.
The revision of IEC 61131:2024 SER focuses on incorporating the latest advancements in programmable controller technology while maintaining backward compatibility with existing systems. It provides guidelines for software development, testing procedures, and maintenance practices, enhancing system robustness and facilitating smoother integration into complex automation networks.
By adhering to this standard, manufacturers can ensure that their PLC products comply with international norms, fostering interoperability and reducing barriers to market entry. End users benefit from a standardized framework that simplifies the selection process for programmable controllers based on specific application needs, thereby accelerating project timelines and minimizing operational risks.
