IEC 62439

Denne samlingen protokoller ser ut til å være rettet mot “redundancy” for generelle kontrollnettverk.

Det kan se ut som at videoen på YouTube bare dekker en standard i en mer generell samling med standarder.

What is the IEC 62439?

IEC 62439 is an international standard that pertains to redundancy protocols for industrial automation and control systems. Specifically, it focuses on the development and implementation of High Availability (HA) and Fault Tolerant (FT) communication networks in industrial settings. The International Electrotechnical Commission (IEC) is responsible for creating and maintaining this standard.

IEC 62439 is divided into several parts, each of which addresses different aspects of redundancy and fault tolerance in industrial networks. Some of the key parts include:

  1. IEC 62439-1: General Concepts and Overview
    • This part provides an introduction to the concept of high availability and fault tolerance in industrial communication networks.
  2. IEC 62439-2: Ring Network
    • Focuses on redundancy mechanisms for Ethernet-based ring topologies commonly used in industrial networks.
  3. IEC 62439-3: Parallel Redundancy Protocol (PRP)
    • Specifies the Parallel Redundancy Protocol, a standardized method for achieving zero-time switchover between redundant network paths.
  4. IEC 62439-4: High-availability Seamless Redundancy (HSR)
    • Covers the High-availability Seamless Redundancy protocol, which is used to provide fault tolerance in Ethernet networks by enabling rapid network recovery.
  5. IEC 62439-5: Media Redundancy Protocol (MRP)
    • Describes the Media Redundancy Protocol, which is used for redundancy in ring topologies and provides a way to ensure network resilience.
  6. IEC 62439-6: Configuration Profiles
    • Provides guidelines for configuring devices and networks according to the IEC 62439 standards.

These standards are particularly important in critical industrial applications where network failures can have serious consequences, such as manufacturing automation, power distribution, transportation systems, and more. By implementing redundancy and fault tolerance mechanisms defined in IEC 62439, organizations can improve the reliability and availability of their industrial communication networks.

Please note that standards may evolve over time, and new revisions or updates may have been released after my last knowledge update in September 2021. Therefore, it’s a good practice to check the latest version of the standard for the most up-to-date information.
