What is EN 50037?

EN50037 is a technical standard that is commonly used in the field of industrial automation. It specifies the requirements for programmable controllers, also known as PLCs (Programmable Logic Controllers), which are widely used in manufacturing and other industrial processes.

The Purpose of EN50037

The main purpose of EN50037 is to ensure the safety and reliability of programmable controllers. It sets out guidelines and criteria that manufacturers must meet in order to design and produce controllers that can operate in a safe and efficient manner.

One important aspect of EN50037 is its focus on functional safety. This means that the standard not only considers the performance and functionality of the controller, but also its ability to respond to potential hazards or failures. By following the requirements of EN50037, manufacturers can create controllers that adhere to industry best practices for safety and security.

Key Requirements of EN50037

EN50037 covers a wide range of topics related to programmable controllers. Some of the key requirements include:

- Hardware specifications: The standard defines the minimum requirements for the hardware components of a programmable controller, such as the CPU, memory, and communication interfaces.

- Programming languages: EN50037 specifies the programming languages that can be used to program a controller, such as ladder logic and structured text. It also provides guidelines for writing clear and readable code.

- Fault tolerance: The standard outlines requirements for fault detection and error handling within a programmable controller. This ensures that the controller can recover from faults and continue to operate safely.

Benefits of EN50037 Compliance

Complying with EN50037 offers several benefits for both manufacturers and end-users of programmable controllers. Firstly, it helps to ensure the safety of industrial processes by reducing the risk of accidents and malfunctions.

Secondly, EN50037 compliance enables interoperability between different brands and models of programmable controllers. This means that end-users have more options when selecting controllers for their specific applications, and can easily integrate them into existing systems.

Finally, EN50037 compliance also enhances the reputation and credibility of manufacturers. By adhering to a recognized industry standard, manufacturers demonstrate their commitment to quality and safety, which can lead to increased customer trust and satisfaction.
