Description

IEC 62439-3 Ed. 4.0 b – Industrial communication networks – High availability automation networks – Part 3: Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR)

The IEC 62439 series is applicable to high-availability automation networks based on the Ethernet technology.

This document:
– specifies PRP and HSR as two related redundancy protocols designed to provide seamless recovery in case of single failure of an inter-bridge link or bridge in the network, which are based on the same scheme: parallel transmission of duplicated information;
– specifies the operation of the precision time protocol (PTP) in networks that implement the two redundancy protocols (Annex A);
– specifies PTP profiles with performance suitable for power utilty automation (Annex B) and industrial automation (Annex C);
– includes for better understanding a tutorial (Annex D) on the PTP features effectively used in high-availability automation networks;
– includes a management information base for PTP (Annex E);
– defines a conformance test suite for the above protocols (Annex F).
