Enterprise-control system integration - Part 5: Business to manufacturing transactions

IEC 62264-5:2011 is based on the use of IEC 62264 abstract models previously defined in IEC 62264-1 and IEC 62264-2 combined with verbs to define a transaction model for information exchange. It is recognized that other non-IEC 62264-5 transaction protocols are possible and are not deemed invalid as a result of this standard. Transactions occur at all levels within the enterprise and between enterprise partners, and are related to both required and actual activities, but the focus of this part of IEC 62264 is the interface between enterprise/business systems and manufacturing systems. It defines business-to-manufacturing transactions and manufacturing-to-business transactions that may be used in relation to the objects that are exchanged between Level 4 and Level 3, as defined in the object models of IEC 62264-1 and IEC 62264-2. Models are introduced which provide descriptions of the transactions and explanations of the required transaction processing behaviour.

Intégration du système de commande d'entreprise - Partie 5: Transactions entre systèmes de gestion de commande d'entreprise et systèmes de fabrication

La CEI 62264-5:2011 définit des transactions en termes d'échanges d'informations entre des applications d'activités commerciales et de fabrication associées aux Niveaux 3 et 4. L'objectif de ces échanges est la capture, l'extraction, le transfert et le stockage des informations, confortant en cela l'intégration du système d'entreprise. La présente partie de la CEI 62264 est conforme aux modèles et à la terminologie de la CEI 62264-1 et aux attributs des modèles d'objet de la CEI 62264-2. Cette norme définit également des transactions spécifiant comment échanger les objets définis à l'Article 7 de la CEI 62264-1, la CEI 62264-2 et la présente norme. Les modèles traités dans la présente norme sont: les modèles associés aux ressources humaine, l'équipement, la maintenance, la matière, le processus, la capacité de production, la définition du produit, l'ordonnancement de production et la performance de production.

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.

INTRODUCTION
This part of IEC 62264 is based on the use of IEC 62264 abstract models previously defined
in IEC 62264-1 and IEC 62264-2 combined with verbs to define a transaction model for
information exchange. It is recognized that other non-IEC 62264-5 transaction protocols are
possible and are not deemed invalid as a result of this standard. Transactions occur at all
levels within the enterprise and between enterprise partners, and are related to both required
and actual activities, but the focus of this part of IEC 62264 is the interface between
enterprise/business systems and manufacturing systems.
This standard defines business-to-manufacturing transactions and manufacturing-to-business
transactions that may be used in relation to the objects that are exchanged between Level 4
and Level 3, as defined in the object models of IEC 62264-1 and IEC 62264-2. Models are
introduced which provide descriptions of the transactions and explanations of the required
transaction processing behaviour.
Technology specific implementations to provide this behaviour are not defined in this
standard. This part of IEC 62264 has the intent of providing insight into the level of work
required to construct transactional exchanges.

Part 5: Business to manufacturing transactions

1 Scope
This part of IEC 62264 defines transactions in terms of information exchanges between
applications performing business and manufacturing activities associated with Levels 3 and 4.
The exchanges are intended to enable information collection, retrieval, transfer and storage in
support of Enterprise-Control system integration. This part of IEC 62264 is consistent with the
IEC 62264-1 models and terminology and IEC 62264-2 object model attributes. This standard
also defines transactions that specify how to exchange the objects defined in IEC 62264-1,
Clause 7, IEC 62264-2 and this standard. Other uses of the transaction model are not defined
in this part.
The models covered in this standard are: Personnel Model, Equipment Model, Maintenance
Model, Material Model, Process Segment Model, Production Capability Model, Product
Definition Model, Production Schedule Model, and Production Performance Model.

4 Transaction messages and verbs
4.1 General
This clause defines a common set of transactions, messages and verbs that shall be used
between Level 4 and Level 3 applications to exchange the data defined in the object models
of IEC 62264-1, Clause 7 and IEC 62264-2.
A transaction shall consist of a sequence of messages, where each message shall have a
structure as defined in 4.2.
Messages shall contain both a verb area and a noun area. Information conveyed in a
message shall be contained in the noun area of a message while the actions associated with
information shall be contained in the verb area.
The role of an application initiating a transaction shall determine the set of verbs to be used in
conducting the transaction. These transaction models are described in 4.2.
Three different transaction models are defined.
a) A PULL transaction model where a user of data requests the data from a provider of the
data.
b) A PUSH model where a provider of data requests an action (processing, changing or
cancelling) on the data by another user.
c) A PUBLISH transaction model where the owner of data publishes it to users (subscribers)
of the data.
– 12 – 62264-5  IEC:2011
NOTE 1 The phrase “owner of data” is used to identify the application that has responsibility for enforcing the
consistency of data.
NOTE 2 This standard does not address the case where there may be multiple systems that can act as the owner
of data. In these situations, configurations should be set up so that one master owner of the data should be
designated, with other systems performing the role of data users.
4.2 Transaction models
There are three classes of actions provided by the verb set: query/reporting, transaction
processing, and data synchronization. These are defined by three different transaction
models.
a) A PULL model where a user of data requests information from an information provider.
This model is used for query/reporting.
Information provider applications listen for GET messages and respond with SHOW
messages to complete the transaction.
Information user applications send GET messages.
1) Requests for information are sent through GET messages.
2) A GET message describes the scope of the requested information.
3) A SHOW message returns the information.
b) A PUSH model where a sender of information sends new or changed information to the
receiver to process requests. This model is used for transaction processing.
Receiver applications listen for PROCESS, CHANGE or CANCEL messages.
Sender applications send PROCESS, CHANGE and CANCEL messages.
1) New information is pushed to the receiver through a PROCESS message. Responses
may be returned to the sender through an ACKNOWLEDGE message.
2) Changes to information are pushed to the receiver through a CHANGE message.
Responses may be returned to the sender through a RESPOND message.
3) Information to be removed is pushed to the receiver through a CANCEL message.
c) A PUBLISH model where the provider of data publishes it to users (subscribers) of the
data. This model is used for data synchronization.
Subscriber applications receive SYNC messages.
Publisher applications send SYNC messages.
1) The publisher sends SYNC messages containing new, changed or deleted information
to subscribers.
2) A subscriber receives SYNC messages containing new, changed or deleted
information.
The timing of the publication and scope of the published information is not defined in a
message. It is determined by an out-of-band agreement between the publisher and
subscriber, therefore there is no SUBSCRIBE message defined in this standard.
Example: An out-of-band agreement means that the agreement is not defined in the transaction protocol.
For example: an agreement between a publisher and subscriber may be set up through configuration
parameters in the applications, or an agreement may be set up dynamically through a web service agreement,
or an agreement may be set up through a third party application.
A single application may support one or more transaction models and the application may
take on multiple roles (sender, receiver, provider and user).
NOTE 1 The transactions are based on the assumption that the exchanged information (noun) is contained in a
message of some form. The exact form of the messages is not defined in this standard; for example, the messages
could be tab delimited files, XML files, electronic mail messages, or data in a named pipe. The exact form of the
transport mechanism for the sending, receiving, listening and publishing of messages is not defined in this
standard.
NOTE 2 The transaction message models do not imply any specific architecture or mechanism for transporting
the messages.
62264-5  IEC:2011 – 13 –
The transactions assume the ability to send an empty or nearly empty message that identifies
either a specific object (typically by ID), a list of specific objects (by a list of IDs), or a class of
objects (by wildcard or property value definition).
Figure 1 illustrates the exchange of messages in a typical transaction, where a message is
sent from the user of information with an identification of an object (GET Equipment), and a
message is returned from the information provider with the object’s information (SHOW
Equipment).
