Industrial communication networks - High availability automation networks - Part 3: Parallel Redundancy Protocol (PRP) and High availability Seamless Redundancy (HSR)
IEC 62439-3:2010(E) is applicable to high-availability automation networks based on the ISO/IEC 8802-3 (IEEE 802.3) (Ethernet) technology. It specifies two redundancy protocols based on the duplication of the LAN, respectively duplication of the transmitted information, designed to provide seamless recovery in case of single failure of an inter-switch link or switch in the network. 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, -

Serija IEC 62439 velja za omrežja za avtomatizacijo z visoko razpoložljivostjo, osnovana na ISO/IEC 8802-3 (IEEE 802.3) (eternet) tehnologiji. Ta del serije IEC 62439 določa dva redundantna protokola, osnovana na podvajanju LAN in podvajanje oddanih informacij v tem zaporedju, ki sta načrtovana tako,da zagotavljata neprehodno okrevanjem v primeru posameznega izpada povezave inter-stikala ali stikala v omrežju.
