IEC 62439-1:2010+A1:2012+A2:2016 is applicable to high-availabilityautomation 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. This consolidated version consists of the first edition (2010), its amendment 1 (2012) and its amendment 2 (2016). Therefore, no need to order amendments in addition to this publication.
