Introduction
This European Standard outlines the main elements of the HBES Open Communication System and
the concept behind it. It should be used as a guideline for the EN 50090 series.
Home and Building Electronic Systems as provided by the HBES Open Communication System are a
specialized form of automated, decentralised and distributed process control, dedicated to the needs
of home and building applications.
The specification of the HBES Open Communication System provides, besides runtime
characteristics, a “toolkit” of services and mechanisms for network management.
On the HBES Open Communication System Device Network, all devices form distributed applications,
which are able to interact with one another taking into account Interworking rules (standardized
Datapoint Types and “Functional Block” objects, modelling logical device channels). This run-time
Interworking allows the creation of a comprehensive and multi-domain home and building
communication system
The available communication media range from Twisted Pair to Powerline and 868 MHz band Radio
Frequency.
The HBES Open Communication system is independent of any specific microprocessor platform or
architecture. Depending on the profile chosen by the manufacturer, any suitable industry-standard
chip can be chosen. Some HBES Open Communication System profiles allow a tiny system footprint
(say < 5 kbit) and can run on an 8-bit processor. Implementations can however also be realised on 16-
or 32-bit processors, or even PC’s.
The features of HBES Open Communication System allow its use in different application domains and
installation types, and also in “Service Network” environments (usually based on broadband networks
running IP, the Internet Protocol). To address this need, the transmission of HBES Open
Communication System frames across an IP network has been standardised in EN 50090-4-3:2007.

1 Scope
This European Standard concentrates on control applications for Home and Building HBES Open
Communication System and covers any combination of electronic devices linked via a digital
transmission network. Home and Building Electronic System as provided by the HBES Open
Communication System is a specialized form of automated, decentralised and distributed process
control, dedicated to the needs of home and building applications.
The EN 50090 series concentrates on HBES Open Communication System Class 1 and includes a
specification for a communication network for Home and Building for example for the control of
lighting, heating, food preparation, washing, energy management, water control, fire alarms, blinds
control, different forms of security control, etc.
This European Standard gives an overview of the features of the HBES Open Communication System
and provides the reader with references to the different parts of EN 50090 series.
This European Standard is used as a product family standard. It is not intended to be used as a stand-
alone standard.
