Overview
EN IEC 61784-2-3:2023 (CLC / CENELEC adoption of IEC 61784-2-3:2023) defines extensions to Communication Profile Family 3 (CPF 3) for Real‑Time Ethernet (RTE). It specifies additional RTE fieldbus profiles based on ISO/IEC/IEEE 8802‑3 (Ethernet) and the IEC 61158 Type 10 family. The standard describes real‑time communication profiles, related network components and the RTE performance indicators and their inter‑dependencies used to specify and verify deterministic Ethernet solutions for industrial automation.
Key topics and technical requirements
- CPF 3 scope and structure: Extensions and profile definitions for CPF 3, including conformance class models and profile architecture for PROFINET/PROFIBUS‑based RTE.
- Profile families and examples: Defined RTE communication profiles (e.g., CP 3/4, 3/5, 3/6, 3/7) with physical, data‑link and application layer descriptions.
- Performance indicators: Specification of RTE performance indicators (latency, jitter, throughput characteristics), their selection, and dependencies used for deterministic behavior assessment.
- Conformance classes & behaviors: Node classes, application classes, communication classes, and expected behaviors for IO controllers, devices, bridges and network components.
- Protocol and timing parameters: Requirements for stack traversal, timing budgets, and protocol parameters relevant to real‑time communication.
- Resilience and redundancy: Media redundancy classes and media class definitions for availability and fault‑tolerant operation.
- Records and management: Communication feature lists, records and configuration/administration numbering to support device interoperability.
- Performance calculation guidance: Annex A provides structural examples and principles for calculating performance indicators.
Applications and who uses it
EN IEC 61784-2-3:2023 is intended for:
- Automation engineers and system integrators designing deterministic Ethernet networks for factories, process plants and machine control.
- Device and network component manufacturers implementing CPF 3 (PROFINET/PROFIBUS‑related) real‑time profiles.
- Network architects and testers who verify RTE performance (latency, jitter, redundancy) and establish conformance.
- Certification bodies and standards committees evaluating interoperability and compliance.
Typical applications include motion control, I/O cyclic communication, and other time‑sensitive industrial control scenarios where deterministic Ethernet behavior is required.
Related standards
Relevant companion and referenced standards include:
- IEC 61158 series (Fieldbus specifications, Type 10)
- IEC 61784-1-3 / IEC 61784-2-0 (CPF 3 base profiles and general concepts)
- IEC 61784-3-3 / IEC 61784-5-3 (functional safety and installation profiles for CPF 3)
- ISO/IEC/IEEE 8802‑3, IEEE 802.1AS, IEEE 802.1Q, IEC 62439‑2
Using EN IEC 61784-2-3:2023 ensures consistent, interoperable implementation of CPF 3 real‑time Ethernet profiles across industrial automation deployments.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretatio
