Foreword
IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of IS0 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.
lS0 and IEC technical committees collaborate in fields of mutual interest. Other international organ-
izations, governmental and non-governmental, in liaison with lS0 and IEC, also take part in the work.
In the field of information technology, IS0 and IEC have established a joint technical committee, lSO/lEC
JTC 1.
The main task of technical committees is to prepare International
Standards, but in exceptional
circumstances a technical committee may propose the publication of a Technical Report of one of the
following types:
- type I, when the required support cannot be obtained for the
publication of an International
Standard, despite repeated efforts;
- type 2, when the subject is still under technical development or where for any other reason there is
the future but not immed iate possibility of an ag reement on a nl nternational Standard
- type 3, when a technical committee has collected data of a different kind from that which is
normally published as an International Standard ( “state of the art ”, for example).
Technical Reports of types 1 and 2 are subject to review within three years of publication, to decide
whether they can be transformed into International Standards. Technical Reports of type 3 do not
necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful.
lSO/IEC TR 15067-2, which is a Technical Report of type 3, was prepared by Joint Technical Committee
ISO/lEC JTC 1, Information technology.
lSO/IEC TR 15067 consists of the following part, under the general title information technology - Home
Electronic Systems (HES) application model.

Introduction
The Home Electronic System is a standard under development by Working Group 1 (WGI) of
Subcommittee 25 (X25), Interconnection of Information Technology Equipment, under Joint Technical
Committee 1 (JTCI) of the IS0 and IEC.
The physical elements constituting lighting control systems are listed. The physical connection of these
elements on a home control system medium is shown. Then, a generic logical model is presented. The
relationship of this model to typical systems of varying complexity is discussed.

Part 2:
Lighting model for HES
1 Scope
This part of lSO/IEC TR 15067 forms the basis for defining HES messages that flow among the logical
components. A preliminary specification for the message set is provided.
2 Physical Lighting Model
21 .
Physical components of a lighting system
2.1.1 Fixture
l Contains one or more lamps.
l May include a microprocessor to store algorithms for lamp operation. Lamp parameters that may be controlled
include on/off, light level, light color, focus, aperture, position in space and orientation, and timing parameters
for changes of state.
l May contain an HES interface. If more than one HES interface is present, each interface and associated lamp(s)
are treated as a separate logical unit in the HES Lighting Model.
l If a fixture does not contain an HES interface, it must be connected to a device concentrator. More than one
fixture may be mounted in one physical box. Each HES interface and associated fixture(s) are treated as a
logical unit. If the fixture(s) is (are) connected to a device concentrator containing an HES interface, that
concentrator and all associated fixtures are treated as one logical unit in the HES Lighting Model. This logical
unit may be modeled as containing multiple objects.
2.1.2 Switch
l A primitive user interface to control fixtures (individually or grouped) or to select scenes (called bghting
moments in theater terminology). Optionally, a switch may include a visible indicator of the state of the fixtures
being controlled.
l May contain an HES interface. If a switch does not contain an HES interface, it must be connected to a device
concentrator. More than one switch may be mounted in one physical box. Each HES interface and associated
switch(es) are treated as a logical unit. If the switch(es) are connected to a device concentrator containing an
HES interface, that concentrator and all associated switches are treated as one logical unit in the HES Lighting
Model. This logical unit may be modeled as containing multiple objects.

2.1.3 Dimmer
l A simple user interface. It may include a simple controller, and may be combined with a switch. It may contain
power modulation circuitry. Optionally, a dimmer may include a visible indicator of the state of the fixtures being
controlled.
e May contain an HES interface. If a dimmer does not contain an HES interface, it must be connected to a device
concentrator. More than one dimmer may be mounted in one physical box. Each HES interface and associated
dimmer(s) are treated as a logical unit. If the dimmer(s) are connected to a device concentrator containing an
HES interface, that concentrator and all associated dimmers are treated as one logical unit in the HES Lighting
Model. This logical unit may be modeled as containing multiple objects.
2.1.4 Sensor
l Measures external parameters, conditions and digitizes the measurement, and transmits the data. Examples
include room occupancy and lighting intensity in the room or externally.
0 May contain an HES interface. If a sensor does not contain an HES interface, it must be connected to a device
concentrator. More than one sensor may be mounted in one physical box. Each HES interface and associated
sensor(s) are treated as a logical unit. If the sensor(s) are connected to a device concentrator containing an HES
interface, that concentrator and all associated sensors are treated as one logical unit in the HES Lighting Model.
This logical unit may be modeled as containing multiple objects.
2.1.5 Device concentrator
l Contains an HES interface.
l Encodes the states of sensors, dimmers, and switches into HES messages. This component is typically
intended for switches, dimmers, and sensors that might not contain individual HES interfaces.
2.1.6 User interface
l A method for the user to select scenes and enter relevant parameters. This component may range from a bank
of switches with some form of user feedback to a video display with keyboard or other I/O, including but not
limited to audio or touch screen.
l May contain an HES interface. If a user interface does not contain an HES interface, it must be connected to an
interface controller. If connected to an interface controller, the combination is considered a single logical unit in
the HES Lighting Model. This logical unit may be modeled as containing multiple objects.
2.1.7 User interface concentrator
A concentrator for accommodating multiple user interface control panels. This component eliminates the need
for intelligence in each user interface.
l Contains an HES interface.
2.1.8 Lighting system controller
l A controller containing algorithms for operating the lighting system. The level of supervision of this controller
over the lighting system components depends on the intelligence of the components, especially the fixtures.
l A lighting system controller may not be needed for simple applications, such as a light switch controlling a light.
More complex applications may be accommodated by intelligence in the switch, dimmer, or user interface and
the fixtures.
l The capabilities of a controller depend on the functions required and the controllers in the fixtures. A
microprocessor-based fixture might need only parameters sent by the controller. For example, for a gradual dim
operation, the fixture could control the rate of dimming to reach a target level in a time interval specified by a
message from the controller. For a dumb fixture, the controller would send a series of level settings.

May include algorithms for sending and receiving messages to/from other system controllers. For example, a
security system controller might send a message to the lighting system controller requesting illumination
where an intruder has been detected.
Contains an HES interface.
2.2 Physical architecture
Each component attached to a home control system network medium must contain an HES interface. Please
note that the user interface concentrator and the device concentrator are present if needed to support user
interfaces, switches, dimmers, and sensor components, which may or may not contain HES interfaces. Figure
1 shows an example of components for a lighting system. In Figure 1, the switches, dimmers, and sensors
sumed to contain HES interfaces.
connected to the medium are a:
3 Logical Lighting Mode
3.1 Logical architecture
The basic premise for the operation of a home automation lighting system is actuation of lamps remotely. Lamp
actuation may be accomplished by a simple switch or dimmer, or by a complex scene programmed into a
controller. The controller may provide synchronization and sequencing among numerous fixtures. Depending on
the intelligence in the fixtures, the controller may actuate each change of lighting state or may set high level
parameters into an intelligent fixture. To accommodate this range of sophistication in a lighting system, logical
models are proposed for a very simple HES lighting system, a complex HES lighting system, and a hierarchically
arranged HES lighting system.
3.2 Logical elements
A new logical element, the lighting activator is introduced to simplify the logical model. The lighting activator
represents a source of signals that control at least one fixture remotely. An activator may be embodied
physically in a simple device that generates on and off signals, such as a switch or a sensor. A lighting activator
could be a hand-held unit with an infrared link that generates HES messages. For complex lighting systems, the
lighting activator may actually be implemented in a microprocessor-based controller.
For logical consistency, another element is introduced. The illuminator represents a source of light and is
typically a physical fixture that includes one or more lamps.
3.2.1 Simple HES lighting system
A simple HES lighting system contai ns one ill urn inator and a simple lighting activator, as in F igure 2 . The simp le
lighting activator woul d be physically a switch or remote cant rol unit. , The fixture may
or may not be intelligent.
The next subclause des cri bes a more complex activator. Note that a simple table lamp with
a built-in switch is
not included in this mod el because it d oes not need the services of a home control system.
3.2.2 Complex HES lighting system
For complex lighting systems, the lighting activator may contain a microprocessor-based controller programmed
with a lighting control algorithm. As shown in Figure 3, the user interfaces, switches, dimmers, and sensors
may be remotely located and linked by the home control system to the activator. The user interface in the
logical model might represent a video terminal for configuring the system while multiple room switches operate
various lighting zones.
The controller in the activator is responsible for establishing priority among the user
