Full title and description
Industrial communication networks — High availability automation networks — Part 1: General concepts and calculation methods (IEC 62439-1:2010+A1:2012+A2:2016). This entry refers to the consolidated edition that incorporates the 2010 first edition and its amendments (A1:2012 and A2:2016), and describes general concepts, definitions, conformance test specifications and calculation methods used across the IEC 62439 series.
Abstract
IEC 62439-1 provides the foundational material for the IEC 62439 series for high-availability Ethernet-based automation networks. It specifies common elements and definitions used by other parts of the series, a normative conformance test specification, an informative classification scheme for network characteristics, a methodology for estimating network availability, and rules and methods to calculate deterministic recovery time for Rapid Spanning Tree Protocol (RSTP). The consolidated 2016 text also documents the introduction of HSR and DRP protocol specifications and related calculation methods.

Scope
Applies to high-availability automation networks based on ISO/IEC 8802-3 (IEEE 802.3) Ethernet technology. It sets out the common elements and definitions for the IEC 62439 series, provides conformance test requirements, defines a classification and methodology for estimating network availability, and gives configuration rules, calculation and measurement methods for deterministic recovery times (notably for RSTP). The consolidated text also references redundancy protocols standardized in other parts of the series (PRP, HSR, DRP).
Key topics and requirements
- Common terminology and definitions for high-availability automation networks.
- Normative conformance test specification for elements of the series.
- Classification scheme for network characteristics and an availability-estimation methodology.
- Configuration rules and calculation/measurement methods for deterministic recovery times in RSTP, including restricted-ring calculations.
- Documentation of redundancy protocols introduced or referenced (HSR, DRP) and their relation to PRP/HSR in other parts of IEC 62439.
Typical use and users
Used by network architects, automation engineers, device and switch vendors, test laboratories and system integrators who design, implement or validate high-availability Ethernet networks in industrial automation, process control and other mission-critical systems where deterministic recovery and high availability are required. It is also used by standards committees and certification bodies as the baseline for conformance testing.
Related standards
Other parts of the IEC 62439 series are directly related, including: Part 2 (Media Redundancy Protocol - MRP), Part 3 (Parallel Redundancy Protocol - PRP and High-availability Seamless Redundancy - HSR), Part 4 (other related media/profiles), Part 5 (Beacon Redundancy Protocol - BRP) and Part 6 (Distributed Redundancy Protocol - DRP). The consolidated Part 1 text cross-references these parts for protocol-specific requirements and test methods.
