Engineering data exchange format for use in industrial automation systems engineering - Automation markup language - Part 1: Architecture and general requirements

IEC 62714-1:2014 is a solution for data exchange focusing on the domain of automation engineering. The data exchange format defined in the IEC 62714 series (Automation Markup Language, AML) is an XML schema based data format and has been developed in order to support the data exchange in a heterogeneous engineering tools landscape. The goal of AML is to interconnect engineering tools in their different disciplines, e.g. mechanical plant engineering, electrical design, process engineering, process control engineering, HMI development, PLC programming, robot programming, etc.

Format d'échange de données techniques pour une utilisation dans l'ingénierie des systèmes d'automatisation industrielle - Automation markup language - Partie 1: Architecture et exigences générales

L'IEC 62714-1:2014 constitue une approche de l'échange de données qui cible le domaine de l'ingénierie de l'automatisation. Le format d'échange de données défini dans la série CEI 62714 (Automation Markup Language, AML) est un format de données de type schéma XML mis au point afin de venir à l'appui de l'échange de données dans un environnement d'outils techniques hétérogène. L'objectif de l'AML est l'interconnexion des outils techniques dans leurs différentes disciplines, par exemple, ingénierie des installations mécaniques, études d'électricité, ingénierie de procédés, ingénierie de commande de processus, développement des IHM, programmation PLC, programmation de robots, etc.

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.

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.

INTRODUCTION
IEC 62714 is a solution for data exchange focusing on the domain of automation engineering.

The data exchange format defined in the IEC 62714 series (Automation Markup Language,
AML) is an XML schema based data format and has been developed in order to support the

data exchange in a heterogeneous engineering tools landscape.

The goal of AML is to interconnect engineering tools in their different disciplines, e.g. me-

chanical plant engineering, electrical design, process engineering, process control engineer-

ing, HMI development, PLC programming, robot programming, etc.

AML stores engineering information following the object oriented paradigm and allows model-
ling of physical and logical plant components as data objects encapsulating different aspects.
An object may consist of other sub-objects, and may itself be part of a larger composition or
aggregation. Typical objects in plant automation comprise information on topology, geometry,
kinematics and logic, whereas logic comprises sequencing, behaviour and control. Therefore,
an important focus in the data exchange in engineering is the exchange of object oriented
data structures, geometry, kinematics and logic.
AML combines existing industry data formats that are designed for the storage and exchange
of different aspects of engineering information. These data formats are used on an “as-is”
basis within their own specifications and are not branched for AML needs.
The core of AML is the top-level data format CAEX that connects the different data formats.
Therefore, AML has an inherent distributed document architecture.
Figure 1 illustrates the basic AML architecture and the distribution of topology, geometry,
kinematics and logic information.

Figure 1 – Overview of the engineering data exchange format AML
Due to the different aspects of AML, the IEC 62714 series consists of different parts focussing
on different aspects:
• IEC 62714-1: Architecture and general requirements
This part specifies the general AML architecture, the modelling of engineering data, clas-
ses, instances, relations, references, hierarchies, basic AML libraries and extended AML
concepts. It is the basis of all future parts, and it provides mechanisms to reference other
sub formats.
– 10 – IEC 62714-1:2014 © IEC 2014

• IEC 62714-2: Role class libraries

This part is intended to specify additional AML libraries.

• IEC 62714-3: Geometry and kinematics

This part is intended to specify the modelling of geometry and kinematics information.

• IEC 62714-4: Logic
This part is intended to specify the modelling of logics, sequencing, behaviour and control

related information.
Further parts may be added in the future in order to interconnect further data standards to

AML.
As long as no further parts describe the integration of further standards, it is important to
focus on a limited set of sub data formats. Otherwise it would open up the usage of any data
format and data exchange would not work.
Annex A gives an informative introduction, use cases and examples regarding AML.
Annex B gives an informative XML representation of the libraries defined in this part of
IEC 62714.

relation between the instance and the corresponding class where the instance is created by
copying the class data structures
Note 1 to entry: The instance receives a copy of all features and properties of the source AML class.
Modifications of the class do not lead to modifications of the instance. Within the instance, class properties are
individualized. Further copies are possible due to the knowledge of the source AML class.
3.1.15
universal unique identifier
UUID
unique identifier for AML objects
Note 1 to entry: This note applies to the French language only.
3.1.16
global unique identifier
GUID
