标准范围

IEC 62439-5:20 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基于网络复制的冗余协议，冗余协议在端节点内执行，而不是内置在交换机中的冗余协议。快速错误检测由两个信标节点提供，切换决策在每个节点中单独做出。跨网络连接能力使得单个连接的端节点能够在两个网络中的任一个上连接。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:-协议现在独立于应用(Path_Check_Request定期发送)；-Failure_Notify消息已被删除；-帧格式已被改变；-添加了新的MAC地址。本出版物应与IEC 62439-1:20 10一起阅读。

IEC 62439-5:2016 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 redundancy protocol that is based on the duplication of the network, the redundancy protocol being executed within the end nodes, as opposed to a redundancy protocol built in the switches. Fast error detection is provided by two beacon nodes, the switchover decision is taken in every node individually. The cross-network connection capability enables singly attached end nodes to be connected on either of the two networks. 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:
- The protocol is now independent of application (Path_Check_Request is sent periodically);
- Failure_Notify message has been removed;
- Frame format had been changed;
- New MAC address had been added.

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