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 2.
The main task of technical committees is to prepare International Standards. 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 document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 18435-1 was prepared by Technical Committee ISO/TC 184, Automation systems and integration,
Subcommittee SC 5, Architecture, communications and integration frameworks.
ISO 18435 consists of the following parts, under the general title Industrial automation systems and
integration — Diagnostics, capability assessment and maintenance applications integration:
⎯ Part 1: Overview and general requirements
The following parts are under preparation:
⎯ Part 2: Descriptions and definitions of application domain matrix elements
⎯ Part 3: Applications integration description method
Introduction
0.1 General
ISO 18435 defines a set of integration methods intended to be used when integrating diagnostics, capability
assessment, and maintenance applications with the applications in production, control, and other
manufacturing operations.
ISO 18435 describes application integration models and common application interoperability requirements.
These application integration models are intended to:
a) provide diagnostics, capability assessment, and maintenance applications’ integration reference
architecture for manufacturing assets, such as equipment, automation devices, and software units;
b) enable integration of diagnostics, capability assessment, and maintenance applications with other
applications;
c) provide for a system view context in dealing with asset management lifecycles.
Application integration models are intended to guide users of industry specifications or standards when
integrating diagnostics, capability assessment, and maintenance applications with production and control
applications. These integration models define elements and rules to help identify and select interfaces
described in the interoperability templates. These interoperability templates are used to reference
interoperability profiles based on international standards that are required for integrating the applications
within and at different levels of an enterprise’s functional and resource hierarchies.
The intended users of ISO 18435 are developers of industrial automation applications, especially those that
design, implement, deploy, commission, and operate the required systems which integrate diagnostics,
capability assessment, control, production, and maintenance applications.
0.2 Asset operation and maintenance lifecycle management integration framework
The main focus of ISO 18435 is to describe the integration requirements that manufacturing assets and
resources need to meet in order to support the operation and maintenance phase within a manufacturing
system’s lifecycle (see Figure 1).

Figure 1 — Scope of ISO 18435 in the lifecycle of a manufacturing system
In Figure 2, the diagnostics and maintenance related activities are shown in a framework, where several
combinations of these activities, as distinguished in scope by the ovals, provide effective mechanisms for
adapting maintenance strategies to various changes in manufacturing operations, such as changes in
production requirements, changes in operational conditions and environment, and changes to continuously
improve manufacturing assets during their lifecycle.

For example, the first combination of activities deals with the operational phase of maintenance task execution,
which consists of maintenance task planning, involving asset inspection, monitoring and diagnostics, followed
by treatment or repair if needed, and ends in the evaluation of maintenance results. These activities are
mainly concerned with controlling routine maintenance tasks.
The second combination of activities focuses on maintenance strategy planning that involves the selection of
an approach for performing maintenance appropriate to each asset with options such as breakdown
maintenance (BM), time-based maintenance (TBM) and condition-based maintenance (CBM). The
maintenance strategies can be improved based on diagnostic capability assessment and maintenance
histories.
The third combination of activities includes manufactu
