BS EN 61131-3:2013

Overview

BS EN 61131-3:2013 is a critical standard in the field of manufacturing engineering, specifically focusing on programmable controllers and their associated programming languages. This standard is part of a broader suite of standards that define the architecture and programming of programmable logic controllers (PLCs). It provides a framework for the development and implementation of control systems in industrial automation.

Key Requirements

The standard outlines several key programming languages that are essential for the effective operation of programmable controllers. These languages include:

• Structured Text (ST): A high-level textual programming language that resembles Pascal, suitable for complex algorithms.
• Instruction List (IL): A low-level language that is similar to assembly language, designed for efficient execution.
• Function Block Diagram (FBD): A graphical language that allows users to create control logic using blocks.
• Sequential Function Chart (SFC): A graphical representation of sequential operations, ideal for process control.
• Ladder Diagram (LD): A graphical programming language that mimics electrical relay logic, widely used in industrial applications.

Each of these languages serves a distinct purpose and can be selected based on the specific requirements of the control system being developed.

Implementation Benefits

Adopting BS EN 61131-3:2013 provides numerous benefits for manufacturers and system integrators:

• Interoperability: The standard ensures that different PLCs and programming environments can work together seamlessly, facilitating integration across diverse systems.
• Flexibility: By supporting multiple programming languages, the standard allows engineers to choose the most appropriate language for their application, enhancing productivity and efficiency.
• Reduced Development Time: Standardised programming languages streamline the development process, enabling quicker deployment of automation solutions.
• Enhanced Maintenance: Clear structure and documentation requirements improve the maintainability of control systems, reducing downtime and operational costs.

Compliance Value

Compliance with BS EN 61131-3:2013 is essential for organisations aiming to meet industry standards and regulations. Adhering to this standard demonstrates a commitment to quality and safety in manufacturing processes. It also provides a competitive advantage by ensuring that systems are built to recognised best practices.

Furthermore, compliance can facilitate easier audits and inspections, as it aligns with international standards set by the International Electrotechnical Commission (IEC). This alignment can be particularly beneficial for companies operating in multiple jurisdictions, as it simplifies compliance with local regulations.

In conclusion, BS EN 61131-3:2013 is a vital standard for anyone involved in the design, implementation, or maintenance of programmable controllers. Its comprehensive framework for programming languages not only enhances technical capabilities but also supports compliance with industry standards, ultimately leading to improved operational efficiency and safety.
