1.1 General 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). 1.2 Code component distribution This document is associated with Code components. Each Code Component is a ZIP package containing at least the electronic representation of the Code Component itself and a file describing the content of the package (IECManifest.xml). The IECManifest contains different sections giving information on: - the copyright notice; - the identification of the code component; - the publication related to the code component; - the list of the electronic files which compose the code component; - an optional list of history files to track changes during the evolution process of the code component. The Code Components associated with this IEC standard are a set of SNMP MIBs. The Code Component IEC-62439-3-MIB.mib is a file containing the MIBs for PRP/HSR and PTP_SNMP. It is available in a full version, which contains the MIBs defined in this document with the documentation associated and access is restricted to purchaser of this document. The Code Components are freely accessible on the IEC website for download at: https://www.iec.ch/sc65c/supportingdocuments/IEC_62439-3.MIB.{VersionStateInfo}.full.zip but the usage remains under the licensing conditions.
