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.
The main task of IEC technical committees is to prepare International Standards. However, a
technical committee may propose the publication of a technical report when it has collected
data of a different kind from that which is normally published as an International Standard, for
example "state of the art".
IEC TR 62453-52-150, which is a technical report, has been prepared by subcommittee 65E:
Devices and integration in enterprise systems, of IEC technical committee 65: Industrial-
process measurement, control and automation.
Each part of the IEC 62453-52-xy series is intended to be read in conjunction with its
corresponding part in the IEC 62453-3xy series. This document corresponds to
IEC 63453-315.

The text of this technical report is based on the following documents:

Full information on the voting for the approval of this technical report can be found in the
report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
The list of all parts of the IEC 62453 series, under the general title Field device tool (FDT)
interface specification, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
This part of IEC 62453 is an interface specification for developers of Field Device Tool (FDT)
components for function control and data access within a client/server architecture. The
specification is a result of an analysis and design process to develop standard interfaces to
facilitate the development of servers and clients by multiple vendors that need to interoperate
seamlessly.
With the integration of fieldbuses into control systems, there are a few other tasks which need
to be performed. In addition to fieldbus- and device-specific tools, there is a need to integrate
these tools into higher-level system-wide planning or engineering tools. In particular, for use
in extensive and heterogeneous control systems, typically in the area of the process industry,
the unambiguous definition of engineering interfaces that are easy to use for all those
involved is of great importance.
A device-specific software component, called Device Type Manager (DTM), is supplied by the
field device manufacturer with its device. The DTM is integrated into engineering tools via the
FDT interfaces defined in this specification. The approach to integration is in general open for
all kind of fieldbusses and thus meets the requirements for integrating different kinds of
devices into heterogeneous control systems.
Figure 1 shows how this part of the IEC 62453-52-xy series is aligned in the structure of the
IEC 62453 series.
