Overview

IEC TR 62453-51-150:2017 is a Technical Report that defines how to integrate IEC 61784 CPF 15 (Modbus TCP® / Modbus Serial Line®) protocol support into Field Device Tool (FDT) systems using the COM implementation. This part of the IEC 62453-51 series focuses on the mapping of Modbus protocol parameters to FDT data types, specifies communication and service implementations based on IEC 62453‑315, and is intended to be used together with IEC TR 62453-41 (Common Object Model). It does not change the FDT specification itself.

Key topics and technical requirements

• Data type mapping: Specifies how Modbus parameters map to FDT datatypes for consistent representation inside FDT/DTM components (protocol-specific usage of general data types).
• Communication and service implementation: Defines implementation patterns for communication services based on IEC 62453‑315 (communication profile for CPF 15).
• Network management and addressing: Introduces Modbus-specific network management data types (e.g., FDTModbusAddressSchema) and how the Modbus device address is represented (e.g., <BusInformation/UserdefinedBus>).
• Access methods and interfaces: References required access methods and interfaces such as IDtmParameter, IDtmSingleDeviceDataAccess, and IDtmSingleInstanceDataAccess, including use of GetParameters and SetParameters.
• Device identification and topology: Covers device type identification, topology scan schemas (DTMModbusDeviceSchema), scan identification, and XSLT transformations for device data.
• Protocol constraints: Notes that restrictions on allowed values and array limits are governed by IEC 61158-5-15 and the MODBUS Application Protocol Specification - implementers must consult these sources for protocol-specific limits.
• XML schema updates: This edition updates the XML schemas used to describe FDT data mappings and communication schemas.

Practical applications and who should use it

• DTM developers and device manufacturers: Use the mappings and schemas to build FDT Device Type Managers that expose Modbus device parameters as FDT data types.
• System integrators and control system vendors: Implement consistent integration of Modbus TCP and Modbus Serial Line devices into heterogeneous engineering tools and SCADA/PLC environments.
• Automation engineers and fieldbus specialists: Leverage the recommended interfaces and data mappings to ensure interoperable device commissioning, diagnostics, and configuration.
• Software architects: Ensure COM-based FDT environments implement the required methods and data schemas for CPF 15 compliance.

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 62453-51-150, which is a technical report, has been prepared by subcommittee 65E:
Devices and integration in enterprise systems, of IEC technical committee 65: Industrial-
process management, control and automation.
This document cancels and replaces IEC TR 62453-515 published in 2009. This edition
constitutes a technical revision. The main changes consist in updates of the XML schemas.
Each part of the IEC 62453-51-xy series is intended to be read in conjunction with its
corresponding part in the IEC 62453-3xy series. This document corresponds to
IEC 62453-315.

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 fieldbuses and thus meets the requirements for integrating different kinds of
devices into heterogeneous control systems.
Figure 1 shows how this part of IEC 62453-51-xy series is aligned in the structure of the
IEC 62453 series.
