What is IEC 62439-6:2018

IEC 62439-6:2018, also known as the International Electrotechnical Commission Industrial communication networks - High availability automation networks - Part 6: Media Redundancy Protocol (MRP) specification, is a technical standard that defines a network protocol for achieving high availability and fault-tolerance in industrial automation systems.

Media Redundancy Protocol (MRP)

Media Redundancy Protocol (MRP) is a key part of IEC 62439-6:2018. It is primarily used in Ethernet-based industrial networks to provide seamless redundancy and uninterrupted communication between devices. MRP ensures that if one network path fails, data can be automatically rerouted through alternate paths, minimizing downtime and ensuring continuous operation.

Benefits of IEC 62439-6:2018 and MRP

Implementing IEC 62439-6:2018 and utilizing MRP in industrial networks brings several benefits:

Increased reliability: MRP enables redundant network paths, ensuring fault tolerance. This eliminates single points of failure and increases the overall reliability of the network.

Seamless network recovery: In the event of a link or device failure, MRP allows for rapid recovery without disrupting ongoing communication. Network traffic is automatically redirected through alternate paths, avoiding any interruptions in data transmission.

Improved performance: With MRP, devices can utilize redundant paths, distributing network traffic evenly. This results in better network performance and reduced latency.

Ease of implementation: IEC 62439-6:2018 provides a standardized protocol for implementing redundancy in industrial networks. This simplifies the design and deployment of high availability automation systems.


IEC 62439-6:2018 and Media Redundancy Protocol (MRP) play a crucial role in ensuring reliable and fault-tolerant communication in industrial automation networks. By implementing this standard, organizations can enhance the availability, performance, and resilience of their systems, resulting in increased productivity and minimized downtime. As technology continues to advance, adherence to standards like IEC 62439-6:2018 becomes increasingly important for building robust and future-proof industrial communication networks.
