标准范围
IEC 62439-3:20 16可作为IEC 62439-3:20 16获得包含国际标准及其红线的RLV版本，显示技术内容与上一版。IEC 62439-3:20 16适用于基于以太网技术的高可用性自动化网络。IEC 62439的这一部分规定了两种冗余协议，旨在在网络中桥间链路或桥接单次故障的情况下提供无缝恢复，它们基于相同的方案:重复信息的并行传输。这第三版取消并取代了2012年出版的第二版。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:-技术修正和规范的扩展；-考虑IEC 61588时钟同步与端到端延迟测量以及PRP中现有的对等延迟测量。
IEC 62439-3:2016 is available as
IEC 62439-3:2016 is applicable to high-availability automation networks based on the Ethernet technology. This part of IEC 62439 specifies two redundancy protocols designed to provide seamless recovery in case of single failure of an inter-bridge link or bridge in the network, which are based on the same scheme: parallel transmission of duplicated information. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- technical corrections and extension of specifications;
- consideration of IEC 61588 clock synchronization with end-to-end delay measurement alongside the existing peer-to-peer delay measurement in PRP.
