Full title and description

St IEC 61784-1-4-2023 — Industrial networks - Profiles - Part 1-4: Fieldbus profiles - Communication Profile Family 4. This part of IEC 61784 defines Communication Profile Family 4 (CPF‑4), a set of protocol-specific communication profiles based on the IEC 61158 series (Type 4) and related standards for use in the design of devices and systems for factory manufacturing and process control.

Abstract

IEC 61784-1-4:2023 specifies CPF‑4: the selection of consistent, compatible subsets of services and protocols from the IEC 61158 (Type 4) model and any necessary constraints on parameter values. It describes the structure and intent of CPF‑4 profiles and cross-references protocol-specific profile definitions (some of which are given in IEC 61784-2-4). The document supports interoperability of fieldbus devices and defines profile behaviour to guide implementers and integrators.

Scope

IEC 61784-1-4:2023 defines the Communication Profile Family 4 (CPF‑4) used for fieldbus profiles that rely on the Type 4 elements of the IEC 61158 series and related standards. The scope covers the definition of protocol-specific communication profiles (CPs), the selection of service and protocol subsets from IEC 61158, and the description of required or optional constraints on parameters. It is intended to guide device designers, manufacturers and system integrators in implementing consistent, interoperable CPF‑4 compliant devices for industrial automation.

Key topics and requirements

• Definition of Communication Profile Family 4 (CPF‑4) and the concept of protocol-specific communication profiles (CPs).
• Mapping and selection of service and protocol subsets from IEC 61158 (Type 4) elements.
• Specification of parameter constraints and mandatory/optional features for CPs to ensure interoperability.
• Reference to protocol-specific CP definitions (some CPs specified in IEC 61784-2-4).
• Normative dependence on IEC 61158 parts (physical, data-link and protocol service definitions for Type 4 implementations).
• Application guidance for factory automation and process control device and system design.

Typical use and users

Typical users include fieldbus and industrial-network device manufacturers, control-system integrators, automation equipment vendors, test and conformance laboratories, and standards committees. The standard is used when designing or verifying device communication stacks, defining interoperable profiles for a product family, or selecting protocols for plant automation and process-control networks.

Related standards

Closely related standards include the IEC 61158 series (industrial communication networks — fieldbus specifications, especially Type 4 parts such as the physical and data‑link/service definitions) and other parts of IEC 61784 (notably IEC 61784-2-4 for some CPF‑4 CP definitions). National and regional adoptions exist as EN/IEC versions. Implementers should consult the referenced IEC 61158 parts for protocol element definitions and IEC 61784-2 parts for specific CPs.
