| Title | Industrial communication networks - High availability automation networks - Part 1: General concepts and calculation methods |
| Project Number | 23217 |
| Abstract/Scope | IEC 62439-1:2010(E) 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. It cancels and replaces IEC 62439 published in 2008 and constitutes a technical revision. It includes the following significant technical changes with respect to IEC 62439 (2008): - adding a calculation method for RSTP (rapid spanning tree protocol, IEEE 802.1Q), - adding two new redundancy protocols: HSR (High-availability Seamless Redundancy) and DRP (Distributed Redundancy Protocol), - moving former Clauses 1 to 4 (introduction, definitions, general aspects) and the Annexes (taxonomy, availability calculation) to IEC 62439-1, which serves now as a base for the other documents, - moving Clause 5 (MRP) to IEC 62439-2 with minor editorial changes, - moving Clause 6 (PRP) was to IEC 62439-3 with minor editorial changes, - moving Clause 7 (CRP) was to IEC 62439-4 with minor editorial changes, and - moving Clause 8 (BRP) was to IEC 62439-5 with minor editorial changes, - adding a method to calculate the maximum recovery time of RSTP in a restricted configuration (ring) to IEC 62439-1 as Clause 8, - adding specifications of the HSR (High-availability Seamless Redundancy) protocol, which shares the principles of PRP to IEC 62439-3 as Clause 5, and - introducing the DRP protocol as IEC 62439-6. |

| Normative reference (6) |
(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved
(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat
(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level
(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement
(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
