FUNCTION BLOCKS (FB) FOR PROCESS CONTROL –

Part 4: EDD interoperability guideline


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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 document may be the subject of patent
rights other than those identified above. 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”.
Technical reports do not necessarily have to be reviewed until the data they provide are
considered to be no longer valid or useful by the maintenance team.
IEC 61804-4, which is a Technical Report, has been prepared by subcommittee 65C: Digital
communications, of IEC technical committee 65: Industrial-process measurement and control.
The text of this Technical Report is based on the following documents:
Enquiry draft Report on voting

TR 61804-4 © IEC:2006(E) – 5 –

Full information on the voting for the approval of this Technical Report can be found in the
report on voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
The list of all the parts of the IEC 61804 series, under the general title Function blocks (FB) for
process control, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until the
maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
A bilingual version of this publication may be issued at a later date.

INTRODUCTION
This Technical Report
• contains an overview of the use of EDDL;
• provides examples demonstrating the use of the EDDL constructs;
• shows how the use cases are fulfilled; and
• shows the proper EDD application interpretation for each example.
This Technical Report is not an EDDL tutorial and is not intended to replace the EDDL
specification.
Instructions are provided for the EDD application, which describe what is to be performed
without prescribing the technology used in the host implementation. For example, the FILE
construct describes data that is to be stored by the EDD application on behalf of the EDD. The
FILE construct does not specify how the data is to be stored. The EDD application can use a
database, a flat file, or any other implementation it chooses.

4 User interface support
4.1 Overview
Most EDD applications can be characterized as either a PC application or a hand-held
application. Due to the relatively small screen of a hand-held device, hand-held applications
can only display a small amount of information at any given time. On the other hand, PC
applications can provide a much more beneficial user interface, largely due to their larger
screen size.
To support the capabilities of PC applications, the MENU construct has been extended in
IEC 61804-3 compared to IEC 61804-2. Due to the differences in the user interfaces of PC
applications and hand-held applications, it is expected that many devices will define two MENU
hierarchies – one for hand-held applications and the other for PC applications. Some MENUs
may be used in both hierarchies. Therefore, the entire hierarchy need not be specified twice.
Different menu structures for different classes of applications are possible. This guideline may
be used to create menu structures in an EDD that are interpreted by applications in an
unambiguous way. To promote interoperability across applications, it is highly recommended
that all EDD applications follow this guideline.
4.2 Menu conventions for applications
There are existing solutions for hand-held application menus and these solutions can be used.
This technical report does not provide specific conventions for hand-held applications.
4.3 Menu conventions for PC-based applications
4.3.1 Overview
EDD applications use special menus in the EDDs to show the user interface of the device.
Such menus are defined for diagnostic, process variables, device features, and offline
configuration. Defined identifiers are defined for the different root menus. Other submenus can
be underneath these root menus.
4.3.2 Diagnostic
The diagnostic menu includes views that show the device state, detailed diagnostic information
and may include graphical views that show, for example, a valve signature.

---------------------- Page: 12 ----------------------

TR 61804-4 © IEC:2006(E) – 9 –
4.3.3 Process variables
The process variable menu includes views that show process measurements and set points
with their quality and important information for process operators, for example, ranges.
4.3.4 Device features
The device feature menu includes features for device support. These features can be split into
process-related and device-specific features. This structure is not required if the number of
features is too small for splitting. Submenus that represent any structuring are allowed on the
device feature menu. In case of such submenus, the menus that are underneath can be split
into process-related and device-specific features.
4.3.5 Offline configuring
This menu hierarchy includes parameters, variables, and methods for offline configuration. It
contains, in particular, all of the application-specific parameters of the device and may also
contain important read-only and writeable variables. For more information about application-
specific parameters, see 4.4. The menu can have offline methods, for example, configuration
assistants.
4.3.6 Overview defined identifiers
Table 1 lists defined menu identifiers.
Table 1 – List of defined menu identifiers
Menu Identifier Short description
diagnostic_root_menu Diagnostic view
process_variables_root_menu Process variable views
device_root_menu Device feature views
offline_root_menu Menu hierarchy for offline configuration

4.3.7 Example of EDD menu structure
This is an example of additional menus that can be added to an EDD for PC applications.
These menus are additional to the existing menus for the applications. This example is HART-
1 2
specific. Examples for Foundation Fieldbus and PROFIBUS would be very similar.
