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.

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.

In industrial automation, a control system often comprises many binary and analog
input/output signals transmitted via a communication network. Numerous field devices
provided by different manufacturers have to be included in the network by direct connection or
I/O multiplex units. Many applications use more than 100 different field device types from
various device manufacturers.
Each device has specific configuration and parameterization functions to support its designed
task. These device-specific properties and settings have to be taken into consideration when
configuring a fieldbus coupler and bus communication for the device. The device presence
and its capability have to be made known to the control system. Device input and output
signals and function block services need to be effectively integrated into the planning of the
control system.
In the absence of a common interface standard, the large number of different device types
and suppliers within a control system project makes the configuration task difficult and time-
consuming. Various different tools have to be used (see Figure 1). The user requirement for
consistency of data, documentation and application configurations can only be guaranteed by
intensive and costly system testing.
A common location for service and diagnostic tasks in the control system does not fully cover
the functional capabilities of available fieldbus devices nor does it guarantee that different
device or module-specific tools can be integrated into other system software tools. Typically,
device-specific tools can only be connected directly to a specific fieldbus or directly to a
specific field device type.

4.2 Objectives of FDT
4.2.1 General features
Full integration of fieldbus devices or modules into automation systems requires a
communication path from central engineering or operator terminals via the system and
fieldbuses to the individual field devices.
FDT supports:
• central facilities for planning, diagnostics and service with direct access to all devices;
• integrated, consistent configuration and documentation of the automation system, its
fieldbuses and devices;
• organization of common data for the automation system and the field devices;
• central data management and data security;
• simple, fast integration of different device and module types into the automation system.
Integration of field devices into the engineering systems of automation technology can cover a
small set of configuration, service and diagnostic functions as well as a large set of functions.
4.2.2 Device and module manufacturer benefits
Figure 2 shows how FDT technology allows integration of individual device and module
properties, including specific characteristics and special features for different device and
module types. Planning and service tools provided by the manufacturer can be integrated as
device or module-specific software components into the engineering system. The
manufacturer is able to define the configuration, service and diagnostic functions and also to
design the appearance of devices and modules in the engineering environment of the
automation system.
This reduces the costs for the manufacturer, as one standardized software component is able
to support configuration, service and diagnostic functions for the device in any automation
system. It also eliminates frequent project-specific or control system-specific adaptations,
which have to be developed and maintained for multiple device and module types in the
absence of a standard.

4.2.3 System manufacturer and integrator benefits
The control system manufacturer or integrator has to implement the defined interfaces for the
integration of all fieldbus devices and modules only once. Manufacturer-specific and/or
device-specific implementations and their maintenance are eliminated.
4.2.4 Other applications
Although FDT is primarily designed to control device functionality and for accessing data to
configure parts of the control system, FDT interfaces can be used in many places within an
application. At the lowest level, they can get raw data from the devices and modules in a
SCADA, DCS or PLC to configure the bus master. At a higher level the Frame Application can
start device-specific diagnosis applications via the DTM. The architecture and design make it
possible to build and to integrate scalable DTMs, where the functionality depends on the
capabilities of the device.
4.3 FDT model
4.3.1 General
FDT facilitates the interaction between device-specific software components, fieldbus
interface-specific software components and host systems (see Figure 3).
• The device-specific software components are called Device Type Managers (DTMs).
• The fieldbus interface-specific software components are called Communication Channels.
• The host systems are called Frame Applications.

Figure 3 – General architecture and components
A Frame Application provides the runtime environment for the DTMs. Typically, the Frame
Application comprises client applications that use DTMs, a database for persistent storage of
device data, and a Communication Channel to the field devices. Client applications are single
applications focusing on specific aspects such as configuration, observation, channel
assignment, and using the service provided by the DTMs.
A DTM encapsulates device-specific software applications and protocol specific definitions.
Thus a Frame Application is able to handle any type of device by integrating corresponding
DTMs without the need for device or fieldbus specific knowledge.
Device and module-specific software components are of several types to cover integration of
products commonly used in automation systems. DTM objects can, for example, represent
normal measurement and control devices. There are specializations of DTMs which represent:
• software entities or function blocks that are movable and may be hosted by different
modules in a network, also known as Block DTM (BTM) objects;
• modular equipment combinations, such as I/O stations with plug in boards to provide
combinations of I/O and control functions also known as Module DTM objects.
A Communication Channel represents the entry point to a fieldb
