Annotation of standard text ČSN EN IEC 62439-3-ed.4 (184022):

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)
