Full title and description

St IEC 61784-2-6-2023 — Industrial networks - Profiles - Part 2-6: Additional real-time fieldbus profiles based on ISO/IEC/IEEE 8802-3 - CPF 6. This part defines extensions to Communication Profile Family 6 (CPF 6) for Real‑Time Ethernet (RTE), specifying RTE communication profiles (CPs) and related network components based on the IEC 61158 series and ISO/IEC/IEEE 8802-3.

Abstract

IEC 61784-2-6:2023 provides extensions to CPF 6 to describe additional real‑time fieldbus profiles for Ethernet-based industrial networks. The document standardizes profile definitions, expected RTE performance indicators and dependencies between those indicators to support interoperability and conformance testing of Real‑Time Ethernet solutions.

Scope

This part of IEC 61784-2 defines extensions of Communication Profile Family 6 (CPF 6) for Real‑Time Ethernet (RTE). It covers the specification of additional RTE communication profiles (CPs), the related network components and the RTE performance indicators and their interdependencies required to characterize deterministic Ethernet‑based fieldbus profiles. The scope explicitly references applicable layers and protocols from IEC 61158 (Types 8 and 10) and ISO/IEC/IEEE 8802-3 as the foundation for the CPF 6 extensions.

Key topics and requirements

• Definition and formalization of additional CPF 6 communication profiles for Real‑Time Ethernet.
• Specification of RTE performance indicators (latency, jitter, synchronicity, throughput where applicable) and dependencies between them.
• Mapping to relevant data‑link and physical layer types in the IEC 61158 family and ISO/IEC/IEEE 8802-3.
• Requirements for network components and services to support the defined profiles and deterministic behavior.
• Support for interoperability and conformance assessment of RTE implementations.

Typical use and users

Used by standards engineers, network architects, device manufacturers, test laboratories and system integrators designing, implementing or certifying deterministic Ethernet solutions for industrial automation. Typical applications include factory automation, motion control, process control systems and other use cases that require bounded latency and real‑time communication over Ethernet.

Related standards

Closely related to IEC 61784-2 (the general part for profiles), the IEC 61158 series (fieldbus protocol types, notably Types 8 and 10 referenced by CPF 6), and ISO/IEC/IEEE 8802-3 (Ethernet). It sits within the IEC 61784 family of standards on industrial network profiles and should be used alongside specifications that define conformance testing and safety profiles where applicable.
