FIELD DEVICE TOOL (FDT) INTERFACE SPECIFICATION –
Part 1: Overview and guidance
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 62453-1 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 2009. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition: introduction of a new implementation technology (defined in IEC 62453-42).

INTRODUCTION

Enterprise automation requires two main data flows: a “vertical” data flow from enterprise

level down to the field devices including signals and configuration data, and a “horizontal”

communication between field devices operating on the same or different communication

technologies.

With the integration of fieldbuses into control systems, there are a few additional tasks to be

performed. The may result in a large number of fieldbus- and device-specific tools in addition

to system and engineering tools. Integration of these tools into higher-level system-wide

planning or engineering tools is an advantage. 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.

Several different manufacturer specific tools are used. The data in these tools are often

invisible data islands from the viewpoint of system life-cycle management and plant-wide

automation.

To ensure the consistent management of a plant-wide control and automation technology, it is

important to fully integrate fieldbuses, devices and sub-systems as a seamless part of a wide

range of automation tasks covering the whole automation life-cycle.

IEC 62453 provides an interface specification for developers of FDT (Field Device Tool)

components to support function control and data access within a client/server architecture.

The availability of this standard interface facilitates development of servers and clients by

multiple manufacturers and supports open interoperation.

A device or module-specific software component, called a DTM (Device Type Manager) is

supplied by a manufacturer with the related device type or software entity type. Each DTM

can be integrated into engineering tools via defined FDT interfaces. This approach to

integration is in general open for all fieldbusses and thus supports integration of different

devices and software modules into heterogeneous control systems.

The IEC 62453 common application interface supports the interests of application developers,

system integrators, and manufacturers of field devices and network components. It also

simplifies procurement, reduces system costs and helps manage the lifecycle. Significant

savings are available in operating, engineering and maintaining the control systems.

The objectives of the IEC 62453 series are to support:
• universal plant-wide tools for life-cycle management of heterogeneous fieldbus

environments, multi-manufacturer devices, function blocks and modular sub-systems for

all automation domains (e.g. process automation, factory automation and similar
monitoring and control applications);

• integrated and consistent life-cycle data exchange within a control system including its

fieldbuses, devices, function blocks and modular sub-systems;

• simple and powerful manufacturer-independent integration of different automation devices,

function blocks and modular sub-systems into the life-cycle management tools of a control

system.

The FDT concept supports planning and integration of monitoring and control applications, it

does not provide a solution for other engineering tasks such as "electrical wiring planning”,

“mechanical planning”. Plant management subjects such as "maintenance planning”, “control

optimization”, “data archiving”, are not part of this FDT standard. Some of these aspects may

be included in future editions of FDT publications.
