Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO
member bodies). The work of preparing International Standards is normally carried out through ISO 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, governmental and non-governmental, in
liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical
Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
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.
Attention is drawn to the possibility that some of the elements of this part of ISO 13281 may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 13281-2 was prepared by Technical Committee ISO/TC 184, Industrial automation
systems and integration, Subcommittee SC 5, Architecture, communications and integration frameworks.
ISO 13281 consists of the following parts, under the general title Industrial automation systems and integration —
Manufacturing Automation Programming Environment (MAPLE):

ISO 13281-2:2000(E)
Introduction
Over the recent past, manufacturing systems have become considerably more flexible and have acquired greater
functionality. The numbers and types of component devices of manufacturing systems, such as NC machines,
robots, automated guided vehicles, programmable controllers and manufacturing cells have increased.
Manufacturing engineers are thus required to develop and update programs not only for many kinds of individual
devices but also for combinations of devices. Due to this fact, the difficulty of integrating and programming the
control of manufacturing operations has increased.
Manufacturing programs have an intense need for a large variety of manufacturing data, including product oriented
data, process oriented data, operation oriented data and management oriented data. This diversity means that
manufacturing data has a much more complicated and varied schema than the processing data encountered in
other systems, e.g., business systems. Therefore, the use and management of manufacturing databases requires a
manufacturing oriented approach. The concept of MAPLE is intended to provide assistance to address this need.
MAPLE assists program developers, planners and operators in a manufacturing automation environment to
generate programs and prepare them for their execution.
MAPLE will assist in the following activities:
a) generation of programs to control devices, cells, shop floors and factories, either manually or with computer
assisted tools;
b) manufacturing and process planning;
c) checking and preparation of resources;
d) preparation of manufacturing data sets for execution (e.g., post processing).
The outcomes of these activities are:
a) manufacturing data sets (e.g., geometry, tools, technology, sequence of operations, setups, measuring,
testing, handling);
b) cell, shop floor and factory monitoring and control programs.
This standard for MAPLE services and interfaces builds upon the functional architecture as specified in
ISO 13281-1. The functional architecture provides a manufacturing data dictionary and a manufacturing software
dictionary that facilitate the separation of the underlying data sources and I/O requirements, in whatever format,
from the executing manufacturing task. Hence, MAPLE provides a mechanism by which a number of diverse data
sources and software tools can be integrated seamlessly.
ISO 13281-1 and 13281-2 are intended to guide software developers of MAPLE environments as well as system
integrators and software tool developers. The standard for MAPLE services and interfaces relies on ISO/IEC DIS
14750 for the interface description language, and ISO/IEC 10746 for presenting Open Distributed Processing
(ODP) view points.
Other relevant work such as aspects of STEP (ISO 10303, Product data representation and exchange) data and
the content of data files used in the NC machining environment for example, will be addressed in a potential new
work item on the MAPLE data dictionary and software program dictionary.
ISO 13281-1 provides an overview of the MAPLE functional architecture in order to aid in the understanding of how
MAPLE services might be provided through a number of functional components within MAPLE, and their internal
and external interfaces.
MAPLE is a building block that can be applied at any level within a manufacturing enterprise. Separate MAPLE
implementations can be configured and connected within an enterprise as required.
