Full title and description

St IEC 61784-1-22: Industrial networks - Profiles - Part 1-22: Fieldbus profiles - Communication Profile Family 22. This part defines Communication Profile Family 22 (CPF 22), a protocol-specific communication profile based on the IEC 61158 series (Type 28), intended for use in the design of devices for factory manufacturing and process control.

Abstract

IEC 61784-1-22:2023 specifies CPF 22 by selecting compatible subsets of services and protocol elements (physical, data-link and application layers) from the IEC 61158 Type 28 family and related standards, and by describing required or optional parameters and constraints to ensure deterministic communication and interoperability for devices that implement the profile.

Scope

Specifies Communication Profile Family 22 (CPF 22) for fieldbus systems: it defines one or more communication profiles that map selected IEC 61158 (Type 28) layer elements to a constrained, interoperable set of services and parameter constraints for devices used in factory automation and process control. The document is limited to profile definition (selections and constraints) rather than detailed installation rules, which are provided in related parts (for example the installation profile in IEC 61784-5-22).

Key topics and requirements

• Definition of CPF 22 profiles and any sub‑profiles (e.g., profile identifiers such as 22/1) mapping to IEC 61158 Type 28 elements.
• Selection and constraint of Physical Layer (PhL), Data‑Link Layer (DLL) and Application Layer (AL) elements needed for deterministic fieldbus communication.
• Specification of required vs optional services and parameter value ranges to ensure interoperability.
• Normative references and dependencies on the IEC 61158 series and other IEC communications/installation standards (installation guidance appears in IEC 61784‑5‑22 and IEC 61918).
• Compatibility statement clarifying that CPs are based on standards or international standards and select consistent, compatible subsets from those standards.

Typical use and users

Used by device and module manufacturers, automation system designers, integrators, test laboratories and certification bodies to implement and verify CPF 22 compliant devices and systems for factory and process automation. It is referenced in product specifications, interoperability testing and when aligning device firmware and network stacks with a standardized fieldbus profile.

Related standards

Closely related to the IEC 61158 series (Type 28) which provides the layer element definitions used by CPF 22; other parts of IEC 61784 (profiles and installation parts) and IEC 61918 (installation of communication networks in industrial premises) are normative or informative references. The installation profile for CPF 22 is specified in IEC 61784‑5‑22 (published 2024), which should be consulted for cabling and installation guidance.

FAQ

Q: What is this standard?

A: IEC 61784‑1‑22:2023 is the part of IEC 61784 that defines Communication Profile Family 22 (CPF 22), a protocol‑specific fieldbus profile based on IEC 61158 Type 28 for industrial automation.

Q: What does it cover?

A: It covers the selection of physical, data‑link and application layer elements and any parameter constraints required to ensure interoperable and deterministic communication for devices implementing CPF 22. Installation practices are covered in related parts such as IEC 61784‑5‑22.

Q: Who typically uses it?

A: Device manufacturers, automation engineers, system integrators, test houses and certification bodies use the standard to design, verify and certify CPF 22‑compliant products and solutions.

Q: Is it current or superseded?

A: IEC 61784‑1‑22 was published as Edition 1.0 on 7 March 2023 and is the current published edition for Part 1‑22; subsequent related installation parts (for CPF 22) were published in 2024. Users should check national adoptions or committee updates for any amendments.

Q: Is it part of a series?

A: Yes — it is part of the IEC 61784 series (Industrial networks — Profiles). CPF 22 is one communication profile family within the broader IEC 61784 framework and depends on layer definitions in IEC 61158 and related IEC documents.
