Overview

IEC 61784-5-21:2018 (consolidated with AMD1:2024) defines the installation profiles for CPF 21 (FL‑net) within industrial communication networks. It specifies which requirements of the reference installation standard IEC 61918 apply to CPF 21 and where those requirements are supplemented, modified, or replaced. The standard is intended to be read together with IEC 61918 and related amendments, and organizes CPF‑specific guidance into a single annex (Annex A) covering planning, implementation, verification, administration and maintenance of fieldbus installations.

Key topics and technical requirements

The CPF 21 installation profile (CP 21/1 - FL‑net) addresses practical, installation‑level requirements including:

• Installation planning
  • Planning requirements and network capabilities (supported data rates, topology constraints)
  • Selection and use of cabling components (balanced copper and optical fibre)
  • Documentation and verification of cabling plans
• Installation implementation
  • Cable routing and installation best practices
  • Connector, terminator and device installation rules
  • Coding, labelling, earthing and bonding of equipment and shielded cabling
  • As‑implemented cabling documentation
• Verification and acceptance testing
  • On‑site installation verification and acceptance test procedures
• Administration, maintenance and troubleshooting
  • Operational administration, maintenance guidance and fault investigation

Notable technical updates in Amendment 1 (2024) include:

• Addition of 1 000 Mbit/s as a supported data rate and inclusion of Category 5e in cabling/connectors tables.
• Revisions to single‑mode silica fibre parameters (bandwidth and optical power budget) for CP 21/1.

Standards referenced in the profile include IEC 61918, IEC 61784‑2, IEC 61158, and cabling norms such as ISO/IEC 11801‑3.

Applications and who uses this standard

IEC 61784-5-21 is targeted at professionals involved in industrial fieldbus and factory automation installations:

• System planners and network designers - to define network capabilities and select appropriate cabling and connectors.
• Installers and commissioning engineers - to follow implementation, termination, earthing and labelling rules.
• Verification and validation personnel - to perform installation acceptance tests and verify conformity to CPF 21 profiles.
• Maintenance teams and integrators - for troubleshooting, administration and lifecycle documentation.
• Device manufacturers and vendors - to ensure hardware and cabling compatibility with CPF 21 installation requirements.

Typical use cases include deploying FL‑net fieldbus segments in manufacturing lines, process automation, and retrofit projects requiring consistent, standards‑based cabling and test procedures.

INTRODUCTION
This International Standard is one of a series produced to facilitate the use of communication
networks in industrial control systems.
IEC 61918:2018 provides the common requirements for the installation of communication
networks in industrial control systems. This installation profile document provides the
installation profiles of the communication profiles (CP) of a specific communication profile
family (CPF) by stating which requirements of IEC 61918 fully apply and, where necessary, by
supplementing, modifying, or replacing the other requirements (see Figure 1).
For general background on fieldbuses, their profiles, and relationship between the installation
profiles specified in this document, see IEC 61158-1.
Each CP installation profile is specified in a separate annex of this document. Each annex is
structured exactly as the reference standard IEC 61918 for the benefit of the persons
representing the roles in the fieldbus installation process as defined in IEC 61918 (planner,
installer, verification personnel, validation personnel, maintenance personnel, administration
personnel). By reading the installation profile in conjunction with IEC 61918, these persons
immediately know which requirements are common for the installation of all CPs and which
are modified or replaced. The conventions used to draft this document are defined in Clause 5.
The provision of the installation profiles in one document for each CPF (for example
IEC 61784-5-21 for CPF 21), allows readers to work with documents of a convenient size.

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
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
This International Standard is one of a series produced to facilitate the use of communication
networks in industrial control systems.
IEC 61918:2018 provides the common requirements for the installation of communication
networks in industrial control systems. This installation profile document provides the
installation profiles of the communication profiles (CP) of a specific communication profile
family (CPF) by stating which requirements of IEC 61918 fully apply and, where necessary, by
supplementing, modifying, or replacing the other requirements (see Figure 1).
For general background on fieldbuses, their profiles, and relationship between the installation
profiles specified in this document, see IEC 61158-1.
Each CP installation profile is specified in a separate annex of this document. Each annex is
structured exactly as the reference standard IEC 61918 for the benefit of the persons
representing the roles in the fieldbus installation process as defined in IEC 61918 (planner,
installer, verification personnel, validation personnel, maintenance personnel, administration
personnel). By reading the installation profile in conjunction with IEC 61918, these persons
immediately know which requirements are common for the installation of all CPs and which
are modified or replaced. The conventions used to draft this document are defined in Clause 5.
The provision of the installation profiles in one document for each CPF (for example
IEC 61784-5-21 for CPF 21), allows readers to work with documents of a convenient size.
