What is BS EN IEC 62439-2- Media Redundancy Protocol about?
BS EN IEC 62439 discusses industrial communication networks. BS EN IEC 62439-2 is the second part of the BS EN IEC 62439 multi-series and discusses Media Redundancy Protocol used in high availability automation networks.
BS EN IEC 62439-2 series is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802-3 (IEEE Std 802.3) (Ethernet) technology.
Who is BS EN IEC 62439-2 - Media Redundancy Protocol for?
BS EN IEC 62439-2 on Media Redundancy Protocol high availability automation networks is useful for:
- Software developers
- Information technology engineers
- Network service providers
Why should you use BS EN IEC 62439-2- Media Redundancy Protocol?
The protocols of the IEC 62439 series provide ISO/IEC/IEEE 8802-3 (IEEE Std 802.3™) compatible, reliable data communication, and preserve determinism of real-time data communication. In cases of fault, removal, and insertion of a component, they provide deterministic recovery times. These protocols retain fully the typical Ethernet communication capabilities as used in the office world so that the software involved remains applicable.
The market needs several network solutions, each with different performance characteristics and functional capabilities, matching diverse application requirements. BS EN IEC 62439-2 provides you with a recovery protocol based on a ring topology, designed to react deterministically on a single failure of an inter-switch link or switch in the network, under the control of a dedicated media redundancy manager node. BS EN IEC 62439-2 helps you by providing relevant principles for high availability networks that meet the requirements for industrial automation networks.
