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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.

A PAS is a technical specification not fulfilling the requirements for a standard but made
available to the public.
IEC-PAS 62453-2 has been processed by subcommittee 65C: Digital communications, of IEC
technical committee 65: Industrial-process measurement and control.

The text of this PAS is based on the This PAS was approved for
following document: publication by the P-members of the
committee concerned as indicated in
the following document
Draft PAS Report on voting
65C/398A/NP 65C/411/RVN
Following publication of this PAS, which is a pre-standard, the technical committee or
subcommittee concerned will transform it into an International Standard.

This PAS shall remain valid for an initial maximum period of three years starting from

2006-05. The validity may be extended for a single three-year period, following which it shall

be revised to become another type of normative document or shall be withdrawn.

IEC 62453 consists of the following parts under the general title Field Device Tool (FDT)

interface specification:
Part 1: Concepts and detailed description

Part 2: INTERBUS communication

Part 3: PROFIBUS communication

Part 4: HART communication
Part 5: FOUNDATION FIELDBUS communication

INTRODUCTION
This PAS is an interface specification for developers of 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 shall inter-operate seamlessly.

With the integration of fieldbusses into control systems, there are a few other tasks which

must be performed. This applies to fieldbusses in general. Although there are fieldbus- and

device-specific tools, there is no unified way to integrate those 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 DTM (Device Type Manager), 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.

Part 2: INTERBUS communication

1 Scope
This part of IEC 62435 provides information for integrating the INTERBUS® protocol into the

FDT interface specification (IEC 62453-1).

2 Normative references
The following referenced documents are indispensable for the application of this PAS. For
dated references, only the edition cited applies. For undated references, the latest edition of
the referenced document (including any amendments) applies
IEC 61158:2003 (all parts), Digital data communications for measurement and control –
Fieldbus for use in industrial control systems
IEC 62453-1, Field Device Tool (FDT) interface specification – Part 1: Concepts and detailed
description
Industrial automation systems and integration – Open systems application
ISO 15745-3,
integration framework – Part 3: Reference description for IEC 61158-based control systems
3 General
INTERBUS schemas are required to define the structure and semantics of the protocol-
specific data transferred via XML documents on the FDT interfaces. The schemas are based
on definitions given in the INTERBUS specification. Furthermore, they contain additional
information about the device that is needed by systems to configure INTERBUS links and to
establish communication between the INTERBUS master and the INTERBUS slave devices.
NOTE For details of the INTERBUS specification, see the IEC 61158 fieldbus series and the “Reference Manual
Peripherals Communication Protocol” available from INTERBUS Club Deutschland e.V.
