What is ISO 55346:2018?

ISO 55346:2018 is a technical standard that provides guidelines and requirements for the use of data communication in process measurement and control systems. It aims to ensure interoperability and compatibility between different devices and systems used in industrial automation.

Importance of ISO 55346:2018

The standard plays a critical role in enabling seamless communication between various components of a process control system, such as sensors, actuators, controllers, and data acquisition devices. It establishes a common language and protocol for exchanging information, allowing for efficient data transmission and integration.

ISO 55346:2018 also helps to reduce costs associated with system integration and maintenance. By adhering to this standard, manufacturers can ensure that their devices and systems are compatible with each other, regardless of the brand or model. This interoperability simplifies the installation and configuration process, saving time and resources.

Main Features of ISO 55346:2018

The standard defines a set of protocols and services for communication in industrial automation systems. Some of the main features include:

1. Communication Profiles: ISO 55346:2018 provides predefined communication profiles, specifying the required communication parameters and data formats for specific applications. These profiles facilitate the plug-and-play functionality, allowing devices from different vendors to work together seamlessly.

2. Protocol Layers: The standard outlines a layered architecture for communication protocols. It defines various layers, such as physical layer, data link layer, network layer, and application layer, each responsible for different aspects of data transmission and control.

3. Message Formats: ISO 55346:2018 specifies standardized message formats for information exchange between devices. These formats ensure consistency and enable effective interpretation of data across different systems, regardless of the underlying technology or hardware.

Conclusion

ISO 55346:2018 is a significant standard in the field of industrial automation. By providing guidelines for communication and interoperability, it simplifies the integration process and enhances the overall efficiency of process control systems. Compliance with this standard enables seamless data exchange between devices from different vendors, fostering innovation and flexibility in the industry.
