IEC 62439

High availability automation networks

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.

IEC 62439:2008(E) is applicable to high-availability automation networks based on the ISO/IEC 8802-3 (Ethernet) technology. It specifies:

- a classification scheme for network characteristics (see Annex A);

- a methodology for estimating network availability (see Annex B);

- a set of communication protocols that realize high availability automation networks via the use of redundancy and that can be used in a variety of applications.
