144 FOREWORD

145 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national

146 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co -operation on all

147 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC

148 publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and

149 Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National

150 Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non -

151 governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the

152 International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two

153 organizations.

154 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus

155 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National

156 Committees.

157 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in

158 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC

159 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.

160 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to

161 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the

162 corresponding national or regional publication shall be clearly indicated in the latter.

163 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment

164 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by

165 independent certification bodies.

166 6) All users should ensure that they have the latest edition of this publication.

167 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its

168 technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature

169 whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of,

170 or reliance upon, this IEC Publication or any other IEC Publications.

171 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable

172 for the correct application of this publication.

173 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC

174 shall not be held responsible for identifying any or all such patent rights.

175 IEC 62769-3 has been prepared by subcommittee 65E: Devices and integration in enterprise systems, of

176 IEC technical committee 65: Industrial-process measurement, control and automation. It is an International

177 Standard.

178 This third edition cancels and replaces the second edition published in 2021. This edition constitutes a

179 technical revision.

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

181 a) added interactive transfer to device.

184 Full information on the voting for its approval can be found in the report on voting indicated in the above

185 table.

186 The language used for the development of this International Standard is English.

187 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in accordance

188 with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available at

189 www.iec.ch/members_experts/refdocs. The main document types developed by IEC are described in

190 greater detail at www.iec.ch/standardsdev/publications.

191 The committee has decided that the contents of this document will remain unchanged until the stability

192 date indicated on the IEC website under "http://webstore.iec.ch" in the data related to the specific

193 document. At this date, the document will be
194 • reconfirmed,

235 3.2 Abbreviated terms and acronyms

236 For the purposes of this document, the abbreviated terms and acronyms given in IEC 62769-1 apply.

237 4 Overview
238 The structure for an FDI Server is shown in Figure 1.

239 FDI Servers that support connectivity with third-party FDI Clients shall support OPC UA. A vendor can

240 provide both an FDI Server and one or more FDI Clients. In this case, the FDI Clients can communicate

241 with the FDI Server through proprietary protocols.

242 An FDI Server communicates with devices via Native Communication (see 7.2.1) and/or Communication

243 Devices (see IEC 62769-7).

244 An FDI Server provides information to FDI Clients through an Information Model (see IEC 62769-5) as

245 follows.

246 • The Information Model includes information about Device Types and Device Instances. The

247 information for a Device Instance includes offline data (engineering data), as well as online data

248 (values from the physical device).

249 • The Information Model is created using information from FDI Packages. However, not all of the

250 information in an FDI Package is reflected in the Information Model.

251 • Referential integrity of the Information Model is maintained using information from FDI Packages.

IEC CDV 62769-3 © IEC:2022 – 11 –

252 • FDI Packages can contain Attachments that contain device manuals and protocol specific

253 information (see IEC 62769-4). Those Attachments, including device manuals and protocol specific

254 support files, are exposed via the Information Model.
255 • FDI Device Packages contain information about device types (see

256 IEC 62769-4). Each device type defined in a package is mapped to a distinct DeviceType node in the

257 Information Model.

258 • FDI Profile Packages are used to provide interaction with devices for which an FDI Device Package

259 does not exist (see IEC 62769-4).

260 • Multiple revisions of an FDI Package generate distinct DeviceType nodes in the Information Model

261 (see IEC 62769-4).

262 FDI Packages contain digital signatures that allow an FDI Server to authenticate their contents (see

263 IEC 62769-4).

264 An FDI Server shall verify the FDI Technology Version (see IEC 62769-1) of any F
