ISO/IEC 9506-2 : 1990 (E)
Foreword
IS0 (the International Organization for Standardization) is a worldwide federation of
national standards bodies (IS0 member bodies). The work of preparing International
Standards is normally carried out through IS0 technical committees. Each member
body interested in a subject for which a technical committee has been established has
the right to be represented on that committee. International organizations, govern-
mental and non-governmental, in liaison with ISO, also take part in the work. IS0
collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to
the member bodies for voting. Publication as an International Standard requires
approval by at least 75 % of the member bodies casting a vote.
International Standard ISO/IEC 9506-2 was prepared by Technical Committee ISO/IEC
TC 184, Industrial automation systems, Sub-Committee SC 5, System integration and
communication.
ISO/IEC 9506 consists of the following parts, under the general title lndustrialautoma-
tion systems - Manufacturing Message Specification :
-
Part 7: Service definition
- Part 2: Protocol specification.

ISO/IEC 9506-2 : 1990 (E)
Introduction
This part of ISO/IEC 9506 provides a wide variety of services useful for various
manufacturing and process control devices. It is designed to be used both by itself and
in conjunction with Companion Standards, which describe the application of subsets
of these services to particular device types.
The services provided by the Manufacturing Message Specification (MMS) range from
simple to highly complex. It is not expected that all of these services will be supported
by all devices. The subset to be supported is limited in some cases by Companion Stan-
dards, and in all cases may be limited by the implementor. Characteristics important in
selection of a subset of services to be supported include:
applicability of the service to the device;
a)
b) the complexity of services and requirements;
c) the complexity of pro vision of a particular class of service via the network ver-
sus the complexity of the device.
Security considerations
When implementing MMS in secure or safety critical applications, features of the OS1
security architecture may need to be implemented. Appropriate features should be
selected from IS0 7498-2 covering safety architectures and features. Those of par-
ticular interest cover the position (in OSI) of
a) access control;
b) authentication;
c) non-repudiation.
Specific implementation methods shall be at the discretion of the implementor.
Complexity of services and requirements
Some MMS services are quite complex and should be considered as advanced func-
tions. Devices used in very simple applications often will not require such advanced
functions, and hence will not support such MMS services.

ISO/IEC 9506-2 : 1990 (E)
General
This part of ISO/IEC 9506 is one of a set of International Standards produced to
facilitate the interconnection of information processing systems. It is positioned within
the application layer of the Open Systems Interconnection Environment as an Applica-
tion Service Element (ASE) with respect to other related standards by the Basic
Reference Model for Open Systems Interconnection (IS0 7498).
The aim of Open Systems Interconnection is to allow, with a minimum of technical
agreement outside the interconnection standards, the interconnection of information
processing systems :
from different manufacturers;
a)
b) under different managements;
c) of different levels of complexity;
of different ages.
d)
Purpose
The purpose of this part of ISO/IEC 9506 is to define the Manufacturing Message
Specification Protocol. It is most closely related to and lies within the field of applica-
tion of the Manufacturing Message Specification Service Definition, ISO/IEC 9506-l.
It also uses and references the Association Control Service Element Definition
(IS0 8649) and the Presentation Layer Service Definition (IS0 8822), whose provisions
it assumes in order to accomplish the aims of the Manufacturing Message Specification
Protocol. The inter-relationship of these International Standards is depicted in
Figure 1.

Figure l- Relatio nship between the Manufacturing
Protocol and adjacent services
The MMS protocol is structured so that subsets of protocol can be defined. The varia-
tions and options available within this part of ISO/IEC 9506 are essential to enable a
Manufacturing Message Specification to be provided for a wide variety of applications.
Thus, a minimally conforming implementation will not be suitable for use in all possi-
ble circumstances. It is important, therefore, to qualify all references to this part of
ISOAEC 9506 with statements of the options provided or required with statements of
the intended purpose of provision or use.
NOTE - The services of this part of ISO/IEC 9506 are generic, and intended to be referenced by
Companion Standards, each of which is directed to a more specific class of application. The ser-
vices of this part of ISO/IEC 9506 may also be used in a stand-alone manner (without the use of
Companion Standards).
It should be noted that, as the number of valid protocol sequences is very large, it is not
possible with current technology to verify that an implementation will operate the pro-
tocol defined in this part of ISO/IEC 9506 correctly under all circumstances. It is possi-
ble by means of testing to establish confidence that an implementation correctly
operates the protocol in a representative sample of circumstances. It is, however, in-
tended that this part of ISO/IEC 9506 can be used in circumstances where two
implementations fail to communicate in order to determine whether one or both have
failed to operate the protocol correctly.

Intended users
The primary aims of this part of ISO/IEC 9506 is to provide a set of rules for com-
munication expressed in terms of the procedures to be carried out by peer MMS entities
at the time of communication. These rules for communication are intended to provide
a sound basis for development in order to serve a variety of purposes:
a) as a guide for implementors and designers;
b) for use in the testing and procurement of equipment;
c) as part of an agreement for the admittance of systems into the open systems en-
vironment ;
d) as a refinement to the understanding of OSI.
This part of ISOAEC 9506 is concerned, in particular, with the communication and in-
terworking of programmable devices on the plant floor. By using this part of
ISOAEC 9506 together with other standards positioned within the OS1 Reference
Model, otherwise incompatible systems may work together in any combination.

Manufacturing Message Specification -
Part 2: Protocol specification
1 Scope
The Manufacturing Message Specification is an application layer standard designed to support messaging communications
to and from programmable devices in a Computer Integrated Manufacturing (CIM) environment.
I .I Specifications
This part of ISOLIEC 9506 specifies:
procedures for a single protocol for the transfer of data and control information fiorn one application entity to a peer
4
application entity in the MMS-context;
the means of selecting the services to be used by the application entities while communicating in the MMS-context;
b)
the structure of the Manufacturing Messaging Specification Protocol Data Units used for the transfer of data and
4
control information.
1.2 Procedures
The procedures are defined in terms of
the interactions between peer application entities through the exchange of Manufacturing Message Specification
4
Application Protocol Data Units;
the interactions between an MMS-provider and the MMS-user in the same system through the exchange of MMS
4
primitives;
the interactions between an MMS-provider and the Association Control Service Element through the exchange of
C>
association control service primitives;
,the interactions between an MMS-provider and a presentation service provider through the exchange of Presentation
4
service primitives.
13 . Applicability
These procedures are applicable to instances of communication between systems which support MMS within the application
layer of the OS1 Reference Model, and which require the ability to interconnect in an open systems interconnection
environment.
1.4 Conformance
This part of ISO/lEC 9506 also specifies conformance requirements for systems implementing these procedures. This part
of ISOAEC 9506 does not contain tests to demonstrate compliance with such requirements.
