What is EN 48187?

In today's rapidly advancing technological landscape, it is essential to have standardized systems and protocols in place for seamless interoperability. One such standard that plays a crucial role in the field of IoT (Internet of Things) and industrial automation is EN48187. But what exactly is EN48187? In this technical article, we will delve into its significance and shed light on its key features.

The Purpose of EN48187

EN48187, also known as "Industrial Communication Networks - Fieldbus Specifications - Functional Safety Communication in a Semi-Duplex Transmission Mode," is an international standard that defines the requirements and guidelines for functional safety communication within fieldbus systems. It primarily focuses on ensuring the reliable transfer of safety-related data between devices in hazardous environments.

This standard is applicable to various sectors, including manufacturing, process industries, robotics, and transportation systems. Its purpose is to provide a common framework for implementing safety measures and communication protocols, enabling devices from different manufacturers to work together seamlessly while maintaining a high-level of safety and reliability.

The Key Features of EN48187

EN48187 specifies several key features that contribute to the achievement of safe and robust communication between devices. These features include:

Semi-Duplex Transmission Mode: EN48187 focuses on semi-duplex transmission, which enables devices to send and receive safety-critical data in a half-duplex mode. This mode ensures optimal utilization of limited communication resources while maintaining the required level of safety.

Segment Type Safety Protocol: The standard defines a segment type safety protocol that facilitates error detection and correction, ensuring data integrity throughout the communication process. This protocol helps identify any issues or faults in the transmission and takes appropriate actions to maintain overall system safety.

Safe State Analysis: EN48187 emphasizes the need for a comprehensive analysis of the system's safe states, including all potential failure scenarios. This analysis helps identify risks and implement suitable safety measures to mitigate those risks effectively.

Compatibility and Interoperability: Ensuring compatibility and interoperability between devices from different manufacturers is a critical aspect of EN48187. The standard provides guidelines for device behavior, configuration, and diagnostic information exchange, making it possible for devices to communicate seamlessly while maintaining safety.

Conclusion

EN48187 serves as a vital standard in the field of industrial communication networks. By providing a framework for functional safety communication and ensuring compatibility between devices, it plays a crucial role in maintaining high-level safety and reliability in various industries. Understanding the purpose and key features of EN48187 is essential for professionals working with IoT devices, automation systems, and related technologies.
