FIELD DEVICE INTEGRATION (FDI) –
Part 115-2: Profiles – Modbus-RTU
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 62769-115-2 has been prepared by subcommittee 65E: Devices
and integration in enterprise systems, of IEC technical committee 65: Industrial-process
measurement, control and automation.
FCG_TS62769-115-2_Profiles_PSD ModbusRTU_1.1.0.4, a specification of the FieldComm
Group, PROFIBUS Nutzerorganisation e. V., OPC Foundation and FDT Group, has served as
a basis for the elaboration of this standard.

1008 FOREWORD
1009 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
1010 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
1011 international co-operation on all questions concerning standardization in the electrical and electronic fields. To
1012 this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
1013 Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
1014 Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
1015 in the subject dealt with may participate in this preparatory work. International, governmental and non-
1016 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
1017 with the International Organization for Standardization (ISO) in accordance with conditions determined by
1018 agreement between the two organizations.
1019 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
1020 consensus of opinion on the relevant subjects since each technical committee has representation from all
1021 interested IEC National Committees.
1022 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
1023 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
1024 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
1025 misinterpretation by any end user.
1026 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
1027 transparently to the maximum extent possible in their national and regional publications. Any divergence
1028 between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
1029 the latter.
1030 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
1031 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
1032 services carried out by independent certification bodies.
1033 6) All users should ensure that they have the latest edition of this publication.
1034 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
1035 members of its technical committees and IEC National Committees for any personal injury, property damage or
1036 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
1037 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
1038 Publications.
1039 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
1040 indispensable for the correct application of this publication.
1041 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
1042 patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
1043 International Standard IEC 62769-115-2 has been prepared by subcommittee 65E: Devices
1044 and integration in enterprise systems, of IEC technical committee 65: Industrial-process
1045 measurement, control and automation.
1046 This document is based on FCG_TS62769-115-2_Profiles_PSD ModbusRTU_1.1.0.4, a specification
1047 of the FieldComm Group, PROFIBUS Nutzerorganisation e. V., OPC Foundation and FDT
1048 Group.
1049 The text of this International Standard is based on the following documents:
