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