FIELD DEVICE INTEGRATION (FDI ) –

Part 6-200: Technology Mapping – HTML5

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.
IEC c0 has been prepared by subcommittee 65E: Devices and integration in enterprise systems,
of IEC technical committee 65: Industrial-process measurement, control and automation. It is
an International Standard.
The text of this International Standard is based on the following documents:

4 Technical concepts
4.1 General
4.1.1 Overview
In 4.1.2, this document describes the technology base for UIP implementation based on HTML5,
the software environment including the related implementation rules. Clause 4 follows a life-
cycle (use case) oriented approach.
Subclause 4.3.4 describes the copy deployment procedures and related implementation rules
®
for the UIP and the FDI Client. UIP instantiation and termination is described in 4.5.
®
Subclause 4.6 defines the rules about interaction between the FDI Client and the UIP. Security
®
related definitions are written in 4.7. The service interface definitions for the FDI Client and
the UIP are found in Clause 5.
®
4.1.2 FDI Type Library
The Device Access Services, the Hosting Services, and the UIP Services are modelled as
TypeScript interfaces passing TypeScript data type arguments. These interfaces and data types
®
are used for the data exchange and interaction between the UIP and the FDI Client. For
runtime error handling purposes during interface method calls TypeScript error objects are
defined.
® ®
The FDI TypeScript interfaces, data types, and exception classes are defined in a single FDI
Type Library. The file name of the interface definition shall be ‘fdi.ts’.

Figure 1 shows the FDI Type Library structure.

®
Figure 1 – FDI Type Library structure
NOTE 1 The composite structure diagram shows only the core interfaces that implement the interfaces defined in
IEC 62769-2.
®
The interfaces shall be implemented by the FDI Client respectively the UIP using TypeScript.
The TypeScript implementation files are transpiled to JavaScript using the feature set specified
in the edition of ECMA 262, which corresponds to the RuntimeId of the UIP variant. The edition
of ECMA 262 is unambiguously specified in the FCG TS10099 by the RuntimId of the UIP
variant.
® ®
The result of the transpilation of FDI .ts is FDI .js, which contains the function prototypes. The
® ®
transpiled FDI Type Library, i.e. FDI .js, and the host specific implementation of the interfaces,
® ®
i.e. host.js, is called FDI Host Type Library. The overall structure of FDI Type Library together
with host and UIP specific implementations of the interfaces is shown in Figure 2.

®
NOTE 2 The FDI Type Library is specified by this specification and can be obtained from FieldcommGroup (see
www.fieldcommgroup.org). Host specific implementation will be provided by host vendors and the UIP specific
implementation will be part of the specific UIP variant.
®
The FDI Type Library fdi.ts respectively the fdi.js shall be versioned as per IEC 62769-1:2021,
® ®
8.1. The FDI Type Library is part of the FDI Core Technology as per IEC 62769-1:2021,
®
8.3.2.1. and therefore directly influences the FDI Technology Version. All Compatible changes
®
of the fdi.ts respectively fdi.js lead to an increase of the minor portion of the FDI Technology
®
Version. Incompatible changes lead to an increase of the major portion of the FDI Technology
Version (see IEC 62769-1:2021, 8.3.2.2).
® ®
The FDI Type Library shall be installed as part of every FDI Client installation. User Interface
®
Plug-Ins (UIP) and the FDI Client Application shall use this instance of the fdi.js. UIPs shall
® ®
not carry or deploy the FDI Type Library. The FDI Client is responsible to provide means to
allow updates of this type library over time.
® ®
The transpiled host specific implementation of the FDI Type Library, i.e. host.js, and the FDI
®
Type Library itself (fdi.js) shall be provided by the FDI Client during the load process of the
UIP. Both files shall be located in the subfolder ‘./scripts’ of the UIP installation folder. The
®
respective files of the FDI Host Type Library fdi.js and host.js shall be referenced by the UIP
explicitly. For example, this can be done with the statements
