FIELD DEVICE INTEGRATION (FDI ) –

Part 6-100: Technology Mapping – .NET

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 62769-6-100 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.

4 Technical concepts
4.1 General
4.1.1 Overview
In 4.1.2, 4.2, 4.3, 4.4, and 4.5, this document describes the technology base for UIP
implementation based on the runtime .NET Framework CLR4, the hardware and software
environment including the related implementation rules. Clause 4 follows a lifecycle (use case)
oriented approach.
Subclause 4.6 describes the copy deployment procedures and related implementation rules for
®
the UIP and the FDI Client. UIP executable instantiation and termination is described in 4.7.
®
Subclause 4.8 defines the rules about interaction between the FDI Client and the UIP. Security
®
related definitions are written in 4.9. 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 and the UIP Services can be modelled as .NET interfaces
passing .NET 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 .NET exceptions classes are defined.

---------------------- Page: 9 ----------------------
– 8 – IEC 62769-6-100:2023 © IEC 2023
® ®
The FDI .NET interfaces, data types, and exception classes are defined in a single FDI Type
®
Library. The FDI Type Library is provided within a Nuget Package, which contains one or more
strong named assemblies. The file name of this Nuget Package shall be Fdi..nupkg.
® ®
The FDI Type Library 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. Therefore, it directly
® ®
influences the FDI Technology Version. All compatible changes of the FDI Type Library 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 version information of the FDI Type Library can be found in FCG TS10099.
® ®
The FDI Type Library is signed with a single unique key by the issuer of the file. The FDI
®
Type Library shall be installed separately as part of every FDI Client installation. User Interface
® ®
Plug-Ins (UIP) and the FDI Client Application shall use this instance of the FDI Type Library.
® ®
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.
®
Figure 1 shows the FDI Type Library structure.

®
Figure 1 – FDI Type Library structure
NOTE The composite structure diagram shows only the core interfaces that implement the interfaces defined in
IEC 62769-2.
4.2 UIP representation
The UIP Variant can contain either a single or multiple runtime modules (.NET Assembly) and
their related supplementary files (for example: resource files). The runtime module of the UIP
Variant is called UIP executable. The supplementary file(s) of the UIP Variant is/are called UIP
supplement(s).
UIP supplement(s) is/are stored under (a) subfolder(s) of the UIP executable installation
directory.
EXAMPLE Examples of UIP supplementary data files include resource files and application configuration data.

---------------------- Page: 10 ----------------------
IEC 62769-6-100:2023 © IEC 2023 – 9 –
®
The supported RuntimeIds and .NET Framework versions for a specific FDI Technology
®
Version are specified in FCG TS10099 FDI Technology Management.
The UIP Variant shall be self-contained. All UIP required libraries (.NET Assemblies) required
by a UIP Variant are stored within the same Folder.
4.3 UIP executable representation
The implementation of the UIP depends on the type of user interface elements that can be
®
embedded into the user interface hosting environment of the FDI Client. UIP shall be
implemented as a .NET System.Windows.Forms class UserControl or a WPF
System.Windows.Controls class UserControl.
UIP executables and their required libraries shall have strong names. The signing of a strong
named Assembly can be done using a self-generated key.
NOTE The identity of strong named Assemblies consists of a name, version, culture, public key token and digital
signature.
UIP executables and their required libraries shall be shipped with file containing the public key
in order to enable Assembly verification.
4.4 UIP executable compatibility rules
The compatibility rules for different versions of the UIP component are specified in IEC 62769-4.
The compilation target platform for the UIP shall be "anyCPU". If this is not feasible the UIP
shall be shipped in two variants. One UIP variant shall be compiled for target platform "x86".
The second UIP variant shall be compiled for target platform "x64". The compilation platform
target shall be described in the catalog.xml file which is defined in IEC 62769-4. This
catalog.xml file contains an xml element "CpuInformation" that describes the User Interface
Plug-in variant. The allowed values that shall be used in the xml element "CpuInformation" are
"anyCPU", "x86" or "x64".
4.5 Allowed .NET CLR versions
4.5.1 General
Specific CLR versions are released for the execution of software components built with
specific .NET Framework versions. The .NET CLR version 4.0 is used to execute software
components built with .NET Framework 4.0. .NET Components are built for one CLR version
only but can be able to run also under a newer CLR version.
® ®
FDI Clients can be built based on CLR version 4.0 or future versions. An FDI Client has to
realize the following situations when starting a UIP.
• When the UIP to be started was built for the same run-time, the UIP can be started in the
®
FDI Client as usual.
• When the UIP to be started was built with another CLR version and is not compiled for the
®
current running CLR version, the FDI Client shall start the UIP in a surrogate process with
the adequate CLR version. (More details are described in 4.5.2.)
Taking this behavior in account, a UIP shall be developed for CLR version 4.0 or any future
version. In case the CLR versions do not match, the UIP shall be started in a separate process.
®
The UIP will then not be displayed as an integrated module within the FDI Client. It is up to
®
the FDI Client to realize the surrogate process.

---------------------- Page: 11 ----------------------
– 10 – IEC 62769-6-100:2023 © IEC 2023
4.5.2 CLR compatibility strategy
®
In the future, FDI Clients and UIPs will be permitted to be built on different incompatible
versions of the CLR.
® ®
If an FDI Client detects that a UIP requires a CLR that is not compatible with the FDI Client,
®
the FDI Client can use a proxy class that enables interaction with the UIP built using a different
version of the CLR.
®
The FDI Client loads a proxy UIP executable, creates an instance of the proxy class, and
delegates the execution of the UIP to this proxy. The proxy starts a process with the required
CLR and executes the UIP in this surrogate process. The proxy classes provide the standard
® ®
FDI interfaces. The FDI Client can use these interfaces to interact with the UIP executed in
the surrogate process.

Figure 2 – .NET surrogate process
4.5.3 How to identify the .NET target platform of a UIP
The .NET target platform CLR version information for which a certain Assembly is compiled can
be extracted by means of .NET Framework library functions (see Figure 3).

Figure 3 – Identification of Run-time Version
®2
NOTE The Visual Studio 2008 and 2010 IDE allow developers to select the .NET Framework target. The selection
®
of a .NET Framework target older than the base for the current Visual Studio IDE automatically creates a
configuration file listed as "app.config" within the solution explorer. This file only reflects the current complier setting.
The compiler does not read that file.
