标准范围

IEC 62439-2:20 16适用于基于ISO/IEC/IEEE 8802-3（IEEE 802.3）（以太网）技术的高可用性自动化网络。IEC 62439系列的这一部分规定了一种基于环形拓扑的恢复协议，旨在在专用介质冗余管理器节点的控制下，对网络中交换机间链路或交换机的单个故障做出确定性反应。第二版取消并取代了2010年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-添加协议扩展以自动选择媒体冗余管理器；-添加协议以冗余地连接媒体冗余协议环。本出版物应与IEC 62439-1:20 10一起阅读。

IEC 62439-2:2016 is applicable to high-availability automation networks based on the ISO/IEC/IEEE 8802-3 (IEEE 802.3) (Ethernet) technology. This part of the IEC 62439 series specifies 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.This second edition cancels and replaces the first edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- adding a protocol extension to select the media redundancy manager automatically;
- adding a protocol to redundantly connect media redundancy protocol rings.

This publication is to be read in conjunction with IEC 62439-1:2010.
