Description of BS EN IEC 61804-3:2020 2020
IEC 61804-3:2020 specifies the electronic device description
language (EDDL) technology, which enables the integration of real
product details using the tools of the engineering life cycle. This
document specifies EDDL as a generic language for describing the
properties of automation system components. EDDL is capable of
describing • device parameters and their dependencies; • device
functions, for example, simulation mode, calibration; • graphical
representations, for example, menus; • interactions with control
devices; • graphical representations: – enhanced user interface, –
graphing system; • persistent data store. EDDL is used to create
electronic device description (EDD) for e.g. concrete devices,
common usable profiles or libraries. This EDD is used with
appropriate tools to generate an interpretative code to support
parameter handling, operation, and monitoring of automation system
components such as remote I/Os, controllers, sensors, and
programmable controllers. Tool implementation is outside the scope
of this document. This document specifies the semantic and lexical
structure in a syntax-independent manner. A specific syntax is
defined in Annex A, but it is possible to use the semantic model
also with different syntaxes. IEC 61804-4 specifies EDD
interpretation for EDD applications and EDDs to support EDD
interoperability. IEC 61804-5 specifies the EDDL builtin library
and provides the profiles of the various fieldbuses.
This fourth edition cancels and replaces the third edition
published in 2015. This edition constitutes a technical revision.
This edition was developed by merging material from multiple
variants of existing EDDL specifications including those from
FieldComm Group (FOUNDATION™ Fieldbus , HART® ), PROFIBUS™
Nutzerorganisation e.V. (PNO), and ISA100_Wirelessâ„¢ Compliance
Institute (ISA100 WCI). Any places where there may be a profile
deviation are now indicated in the context where the related
deviation is found. As a result, the formatting and numbering of
this edition may be different from any of the individual
specifications from which this edition was derived. This edition
includes the following significant technical changes with respect
to the previous edition: • Communication profiles ISA100 and GPE
were added. • EDD Identification Information has a new LAYOUT_TYPE
attribute. • New construct SEMANTIC_MAP was added. • CLASS
attribute values LOCAL_A and LOCAL_B were added. • Extended LIST
functionality to support device managed lists.
