Full title and description

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

Abstract

IEC 61784-2-2:2023 provides the CPF 2 extensions that describe RTE communication profiles and their expected RTE performance characteristics and dependencies. The document is intended to enable consistent implementation and conformance testing of CPF 2 profiles built on Ethernet technologies and the IEC 61158 family.

Scope

This part of IEC 61784 defines extensions of Communication Profile Family 2 (CPF 2) for Real‑Time Ethernet (RTE). It specifies the structure and content of CPF 2 communication profiles, identifies relevant RTE performance indicators and the dependencies between them, and references the IEC 61158 series (Type 2 elements), ISO/IEC/IEEE 8802-3 and other applicable standards used to achieve RTE functionality. The profiles described are intended to coexist with standard Ethernet and, where necessary, to amend lower-layer behaviour to obtain deterministic or bounded‑latency performance.

Key topics and requirements

• Definition and description of CPF 2 Real‑Time Ethernet communication profiles (CPs).
• Specification of RTE performance indicators relevant to each profile and how those indicators depend on network components and configuration.
• Normative references and linkage to IEC 61158 parts for the physical and data‑link layer elements used by CPF 2 CPs.
• Requirements to ensure interoperability with ISO/IEC/IEEE 8802-3 Ethernet and related timing/synchronization standards (for example IEC 61588 where used).
• Guidance to support conformance testing and consistent implementation of RTE features in CPF 2 devices.

Typical use and users

Used by device manufacturers, system integrators, test laboratories and standards bodies involved in industrial automation and real‑time networking to design, specify and validate Real‑Time Ethernet products and solutions. Typical applications include factory automation, process control and other industrial systems requiring deterministic Ethernet communication.
