Full title and description

Industrial communication networks - Profiles - Part 5-3: Installation of fieldbuses - Installation profiles for CPF 3 (consolidated edition incorporating IEC 61784-5-3:2018 and Amendment 1:2024). This consolidated publication defines installation profiles and related installation requirements for Communication Profile Family 3 (CPF 3), intended to be read in conjunction with IEC 61918.

Abstract

This standard specifies installation profiles for CPF 3 (PROFIBUS/PROFINET family), providing requirements and annexed installation profiles that state which requirements of IEC 61918 apply and where they are supplemented, modified or replaced. The 2024 amendment introduces technical changes including support for 4‑pair cabling, addition of M12 X‑Coding connectors, definition of end‑to‑end links, revisions to certain installation tables and a formula for NEXT limits for end‑to‑end links.

Scope

The document defines installation profiles for the Communication Profile Family 3 (CPF 3), describing physical-layer and installation requirements (cabling, connectors, end‑to‑end link definitions and electrical parameters) necessary to install CPF 3 fieldbus systems. The annexes contain the specific installation profiles and are intended to be read in conjunction with IEC 61918 and other referenced connector/cabling standards. The amendment A1:2024 updates and extends the original 2018 requirements to reflect new cabling and connector options and measurement limits.

Key topics and requirements

• Installation profiles for CPF 3 (PROFIBUS/PROFINET family) — requirements and annexed profiles.
• Physical cabling specifications including support for 4‑pair cabling where applicable.
• Connector requirements and additions (notably M12 X‑Coding where specified).
• Definition and requirements for end‑to‑end links, including formalisms for NEXT limits and other signal‑integrity measures.
• Cross‑references and compatibility statements with IEC 61918 and related connector/cabling standards.
• Installation tables, test limits and measurement guidance for field installations.

Typical use and users

This standard is used by control system designers, automation engineers, site installers, system integrators, cable and connector manufacturers, test laboratories and standards/quality engineers who specify or validate installation practices for CPF 3 fieldbus networks in industrial automation environments. It supports procurement specifications, installation checklists, factory acceptance and site testing procedures.

Related standards

Commonly referenced documents include IEC 61918 (communication profile rules and application), other parts of the IEC 61784 series (installation and profile definitions), and connector/cabling standards from the IEC 60603 and IEC 61076 series. The amendment explicitly lists several IEC connector and cabling standards as normative or informative references.

FAQ

Q: What is this standard?

A: IEC 61784-5-3 (consolidated with Amendment 1:2024) is the IEC installation‑profile standard that defines how CPF 3 fieldbus systems should be installed — covering cabling, connectors, link definitions and test limits.

Q: What does it cover?

A: It covers installation profiles for CPF 3 (PROFIBUS/PROFINET family), specifying which requirements of IEC 61918 apply and providing annexed profiles that supplement, modify or replace other requirements for practical installation and testing. The 2024 amendment adds cabling and connector options and refines measurement limits.

Q: Who typically uses it?

A: System integrators, automation and control engineers, installers, cable and connector manufacturers, test labs and standards bodies use it to design, specify, install and verify CPF 3 fieldbus installations.

Q: Is it current or superseded?

A: The consolidated edition incorporating Amendment 1 (published March 26, 2024) is the current published consolidated version; it amends and updates the 2018 edition. IEC lists the consolidated/CSV edition as edition 4.1 with a stability date noted in the IEC record.

Q: Is it part of a series?

A: Yes — IEC 61784 is a multi‑part series covering communication profiles; Part 5 addresses installation of fieldbuses and Part 5-3 specifically addresses CPF 3 installation profiles. The standard is also intended to be used alongside IEC 61918 and related connector/cabling standards.

Q: What are the key keywords?

A: CPF 3, installation profiles, fieldbus installation, PROFINET, PROFIBUS, cabling, M12 X‑Coding, end‑to‑end link, NEXT, IEC 61918.
