Full title and description

IEC 61784-5-20:2018 — Industrial communication networks - Profiles - Part 5-20: Installation of fieldbuses - Installation profiles for CPF 20 (ADS‑net). This part specifies the installation profiles (planning, cabling, implementation, verification and conformance statements) for CPF 20 communication profiles to be used in conjunction with IEC 61918.

Abstract

This standard defines installation profiles for CPF 20 (ADS‑net and its variants) and sets out which requirements of IEC 61918 apply, and where needed how they are supplemented, modified or replaced. Normative installation profiles for CP 20/1 (ADS‑net/μΣNETWORK‑1000) and CP 20/2 (ADS‑net/NX) are given in normative annexes; the profiles cover installation planning, cabling component selection, connector and terminator requirements, earthing/shielding, labelling, and acceptance testing.

Scope

IEC 61784-5-20:2018 specifies installation profiles for the CPF 20 family (ADS‑net) by identifying which clauses of IEC 61918:2018 apply and by providing profile-specific additions, modifications or replacements. The normative annexes contain the CP‑specific installation requirements (notably for CP 20/1 and CP 20/2). The profiles are intended to be used together with IEC 61918 (installation of communication networks in industrial premises).

Key topics and requirements

• Normative installation profiles for CPF 20 variants (CP 20/1 and CP 20/2) — scope and profile-specific normative references.
• Installation planning: documentation, network capability analysis, selection and use of cabling components.
• Cabling and connector requirements: balanced copper and fibre guidance, connector types, fixed cabling vs cords, routing and segregation.
• Implementation details: cable installation, connector and terminator installation, device placement, coding and labelling conventions, earthing and shielding requirements.
• Verification and acceptance: installation verification, acceptance test procedures and as‑implemented documentation.
• Conformance statements: how to declare compliance to a specific CP 20/n installation profile (format and wording).

Typical use and users

Used by industrial network designers, site and cabling installers, system integrators, plant engineers, equipment manufacturers and testing/acceptance teams to ensure CPF 20 (ADS‑net) installations meet consistent, interoperable and verifiable cabling and installation practices. It is also referenced by certification bodies and procurement specifications for CPF 20 systems.

Related standards

Primary related documents include IEC 61918 (Installation of communication networks in industrial premises), other parts of IEC 61784 (communication profiles family and CP definitions such as IEC 61784‑2), and lower‑layer protocol standards referenced by CPF 20 profiles. Users should consult IEC 61784 (all relevant parts) and IEC 61918 alongside this part for a complete installation and conformance picture.

Q: What does it cover?

A: It covers installation planning, cabling component selection, connector and terminator installation, device mounting and labelling, earthing and shielding, and installation verification and acceptance tests for CPF 20 profiles; the normative annexes give CP‑specific requirements.

Q: Who typically uses it?

A: Network engineers, system integrators, cabling contractors, plant automation engineers, equipment vendors and conformity/acceptance testers working with CPF 20 (ADS‑net) systems.

Q: Is it current or superseded?

A: The published edition is Edition 1.0 (2018). The IEC publication entry lists the document as published on 30 August 2018 and shows a stability date indicating it is current through (and expected stable until) 2028; users should check national adoptions for local publication dates and amendments.

Q: Is it part of a series?

A: Yes — it is Part 5‑20 of IEC 61784 (Profiles). IEC 61784 is a multi‑part series covering communication profiles; Part 5 contains installation profiles and other parts cover communication profile definitions and application layer protocols. This part is intended to be used together with IEC 61918 for installation guidance.
