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 61918:2013 provides the common requirements for the installation of communication
networks in industrial control systems. This installation profile standard 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 standard, see IEC 61158-1.
Each CP installation profile is specified in a separate annex of this standard. 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 standard are defined in Clause 5.
The provision of the installation profiles in one standard for each CPF (for example
IEC 61784-5-16 for CPF 16), allows readers to work with standards of a convenient size.

Where there is no corresponding subclause of IEC 61918 in the normative annexes in this
standard, the subclause of IEC 61918 applies without modification.
The annex heading letter represents the installation profile assigned in Clause 4. The annex
heading number shall represent the corresponding numbering of IEC 61918.
EXAMPLE “Subclause A.4.4” in IEC 61784-5-16 means that CP 16/2 specifies the subclause 4.4 of IEC 61918.
All main clauses of IEC 61918 are cited and apply in full unless otherwise stated in each
normative installation profile annex.
If all subclauses of a (sub)clause are omitted, then the corresponding IEC 61918 (sub)clause
applies.
If in a (sub)clause it is written “Not applicable.”, then the corresponding
IEC 61918 (sub)clause does not apply.
If in a (sub)clause it is written “Addition:”, then the corresponding IEC 61918 (sub)clause
applies with the additions written in the profile.
If in a (sub)clause it is written “Replacement:”, then the text provided in the profile replaces
the text of the corresponding IEC 61918 (sub)clause.
NOTE A replacement can also comprise additions.
If in a (sub)clause it is written “Modification:”, then the corresponding IEC 61918 (sub)clause
applies with the modifications written in the profile.
If all (sub)clauses of a (sub)clause are omitted but in this (sub)clause it is written
“(Sub)clause x has addition:” (or “replacement:”) or “(Sub)clause x is not applicable.”, then
(sub)clause x becomes valid as declared and all the other corresponding
IEC 61918 (sub)clauses apply.
6 Conformance to installation profiles
Each installation profile within this standard includes part of IEC 61918:2013. It may also
include defined additional specifications.
A statement of compliance to an installation profile of this standard shall be stated as either
