BS EN IEC 62439-3:2018

This standard BS EN IEC 62439-3:2018 Industrial communication networks. High availability automation networks is classified in these ICS categories:

• 35.110 Networking
• 35.100.05 Multilayer applications
• 35.040.01 Information coding in general
• 25.040.40 Industrial process measurement and control
• 25.040.01 Industrial automation systems in general

IEC 62439-3:2016 is available as IEC 62439-3:2016 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62439-3:2016 is applicable to high-availability automation networks based on the Ethernet technology. This part of IEC 62439 specifies two 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. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- technical corrections and extension of specifications;
- consideration of IEC 61588 clock synchronization with end-to-end delay measurement alongside the existing peer-to-peer delay measurement in PRP.
