FIELD DEVICE INTEGRATION (FDI) –
Part 1: Overview
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.
International Standard IEC 62769-1 has been prepared by subcommittee 65E: Devices and
integration in enterprise systems, of IEC technical committee 65: Industrial-process
measurement, control and automation.This second edition cancels and replaces the first edition published in 2015. This edition
constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous
edition:a) support for generic protocol extension for faster adoption of other technologies;
b) digital signature now include trusted timestamping for long term validation of FDI Package;
c) support of new protocols.---------------------- Page: 6 ----------------------

4 Background
4.1 Motivation
In today’s automation systems, field devices from many different suppliers have to be integrated
into the system, which results in additional effort for installation, version management and
operation of these devices. This challenge is best met with an open and standardized device
integration solution.___________

Two different device integration technologies exist: the Electronic Device Description Language
(EDDL) in accordance with IEC 61804 and the Field Device Tool (FDT ) in accordance with
IEC 62453. While these technologies take different approaches to solve the problem, there is a
lot of overlap between them. This has led to a situation where the technologies compete instead
of complementing each other. As a result, system suppliers have taken their positions, device
suppliers have had to double their efforts in order to support EDDL and FDT , and the end
users have become frustrated because they want the best of both technologies.For all parties involved, the ideal solution looks different. System suppliers want to
