Information technology - Home electronic system - Guidelines for product interoperability - Part 1: Introduction
Specifies requirements for product interoperability in the area of home and building automation systems, with sufficient detail needed to design interoperable Home Electronic System products. The widespread development of many national standard and proprietary networks within and to the home has necessitated a standard for interoperability among home system applications and products from multiple manufacturers. Where widely varying devices need to interoperate, it is desirable that they do so seamlessly to present a single, uniform network and hence to deliver a variety of applications. Examples of such applications are lighting control, environmental control, audio/video equipment control and home security. Although a single uniform home control system would simplify operations, this standard recognises that multiple different networks may co-exist in the same house, and therefore applies to devices connected to a single home control system or to different home control systems. It ensures that, where applications on the same or dissimilar networks co-exist within premises and are required to interoperate, they will do so in a safe, reliable, predictable and consistent manner. It specifies requirements to assure that devices from multiple manufacturers work together to provide a specific application; a specific device could also be used for multiple applications. Interoperability requirements are given with respect to safety, addressing, applications, transport of information, management, and set-up of devices/elements within home networks static and/or dynamic binding between objects. This part defines the components of interoperability for the purpose of providing a framework within which subsequent parts of the standard will be drafted. This part applies to components within networks, between networks and located within dissimilar networks, as well as to devices located at the junction of dissimilar networks.

FOREWORD
1) ISO (International Organization for Standardization) and IEC (International Electrotechnical Commission) form the
specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in
the development of International Standards through technical committees established by the respective
organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in
fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with
ISO and IEC, also take part in the work.
2) In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
3) All users should ensure that they have the latest edition of this publication.
4) No liability shall attach to IEC or ISO or its directors, employees, servants or agents including individual experts
and members of their technical committees and IEC or ISO member bodies 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 of, use of, or reliance upon, this ISO/IEC publication or any other IEC,
ISO or ISO/IEC publications.
5) 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.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of
patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.
International Standard ISO/IEC 18012-1 was prepared by subcommittee 25: Interconnection
of information technology equipment, of ISO/IEC joint technical committee 1: Information
technology.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
ISO/IEC 18012 consists of the following parts, under the general title Information technology –

INTRODUCTION
The widespread development of many national standard and proprietary networks within and
to the home has necessitated a standard for interoperability among home system
applications. This standard will ensure that applications on the same or dissimilar networks
co-exist within premises and are required to interoperate, they will do so in a safe, reliable,
predictable and consistent manner. This part defines the components of interoperability for
the purpose of providing a framework within which subsequent parts of the standard will be
drafted. This part applies to components within networks, between networks and located
within dissimilar networks. It also applies to devices located at the junction of dissimilar
networks.
In the field of home and building automation, products from multiple manufacturers may need
to interoperate. Where widely varying devices need to interoperate, it is desirable that they do
so seamlessly to present a single, uniform network and hence to deliver a variety of
applications. Examples of such applications are lighting control, environmental control,
audio/video equipment control and home security.
With reference to Figure 1, where there are two (or more) dissimilar networks within the same
premises, they must conform to this standard if, when linked by some physical means, they
are expected to behave as if both networks were logically the same network.

This document comprises the following sections.
• A conformance section (clause 4) with which all interoperating networks and intermediary
equipment on the home electronic system comply.
• A requirements section (clause 5) that defines the normative functional safety
requirements of product interoperability of HES products and networks, where these are
not covered by existing functional safety standards.
• A requirements section (clause 6) that defines the management of product interoperability
among HES products and networks.
• A requirements section (clause 7) that defines the normative operational requirements of
product interoperability among HES products and networks.

GUIDELINES FOR PRODUCT INTEROPERABILITY –
Part 1: Introduction
1 Scope
This part of ISO/IEC 18012 specifies requirements for product interoperability in the area of
home and building automation systems. It specifies layers six and seven of the OSI reference
model (see ISO/IEC 7498-1) with sufficient detail needed to design interoperable home
electronic system products, while layers one to five are only specified to the point needed to
check whether devices will be able to interoperate with one another.
ISO/IEC 18012-1 is applicable to
• stand-alone local/home networks, connected devices and applications,
• mixed local/home networks, connected devices and applications,
• automatically configured devices,
• installer configured devices,
• installer configured groups/clusters of devices.
ISO/IEC 18012-1 specifies interoperability for system set-up, operation and management
applied to devices connected to a single home control system or to different home control
systems. Although a single uniform home control system would simplify operations, this
standard recognises that multiple different networks may co-exist in the same house. This
standard specifies requirements to assure that devices from multiple manufacturers work
together to provide a specific application. Also, a specific device could be used for multiple
applications.
ISO/IEC 18012-1 specifies interoperability requirements with respect to
• safety,
• addressing,
• applications,
• transport of information,
• set-up of devices/elements within home networks – static and/or dynamic binding between
objects,
• management.
This document does not specify how two home control systems share a common resource or
how to ensure that two home control systems used within the same premises do not interfere
with each other. However, this document requires that two home control systems may share a
common resource, and that they do not interfere with one another.
