IEC 62439-1:20 10适用于基于ISO/IEC 8802-3（IEEE 802.3）（以太网）技术的高可用性自动化网络。它规定:-IEC 62439系列其他部分的共同要素和定义；-一致性测试规范（规范性）；-用于网络特性的分类方案(信息性的)；-用于估计网络可用性的方法(信息性)；-RSTP中确定性恢复时间的配置规则、计算和测量方法。本标准取消和取代2008年发布的IEC 62439，构成技术修订。它包括以下变化:-用于RSTP(快速生成树协议，IEEE 802.1 Q)的新计算方法，-两种新的冗余协议:HSR（高可用性无缝冗余）和DRP（分布式冗余协议），-计算受限配置(环)中RSTP的最大恢复时间的新方法，符合IEC 62439-1作为条款8，HSR(高可用性无缝冗余)协议的新规范，其与IEC 62439-3作为条款5共享PRP的原理，以及-引入DRP协议作为IEC 62439-6。这个双语版本（2013-07）对应于2010-02年出版的单语英文版。

IEC 62439-1:2010 is applicable to high-availability automation networks based on the ISO/IEC 8802-3 (IEEE 802.3) (Ethernet) technology. It specifies:
- the common elements and definitions for other parts of the IEC 62439 series;
- the conformance test specification (normative);
- a classification scheme for network characteristics (informative);
- a methodology for estimating network availability (informative);
- the configuration rules, calculation and measurement method for a deterministic recovery time in RSTP. This standard cancels and replaces IEC 62439 published in 2008 and constitutes a technical revision. It includes the following changes:
- a new calculation method for RSTP (rapid spanning tree protocol, IEEE 802.1Q),
- two new redundancy protocols: HSR (High-availability Seamless Redundancy) and DRP (Distributed Redundancy Protocol),
- a new method to calculate the maximum recovery time of RSTP in a restricted configuration (ring) to IEC 62439-1 as Clause 8, new specifications of the HSR (High-availability Seamless Redundancy) protocol, which shares the principles of PRP to IEC 62439-3 as Clause 5, and
- introduces the DRP protocol as IEC 62439-6. This bilingual version (2013-07) corresponds to the monolingual English version, published in 2010-02.
