The KNX bus system is a building management
system with a control bus
system tailored to suit the electrical
installations. Leading European companies
in electrical installation engineering
– including JUNG – founded
an organisation with the aim to achieve
a standardisation of the system and
widespread acceptance of the KNX in
Europe and worldwide. KNX is a "Societe
Coopérative" under Belgian law with
its headquarters in Brussels. The trademark
KNX visually underlines the system
compatibility of the products.
The purpose of the organisation is to
promote building management systems
in a standardised form on the European
market, to achieve fast, widespread
market acceptance and develop the
trademark to a seal of quality. Technical
guidelines for the system and the products,
together with quality regulations
will be drawn up by the company accordingly.
This will ensure that KNX bus
equipment from various manufacturers
within a system can communicate with
each other.
The KNX system
The demands made on modern electrical
installations in private homes and on
business premises have changed considerably.
More and more emphasis
is being placed on safety, operational
ease and flexible use. The limits for conventional-
electrical installations with a
confusing number of own functional
networks for electrical power, heating,
lighting and shutter control, burglar
alarm system, smoke, gas and fire
detectors, however, have long been
reached.
Installation and power costs have risen.
Subsequent upgrading, renovation and
change of system operation is expensive
and complicated. The KNX System offers
a convincing perspective. The KNX
System is an intelligent building management
system for measuring, regulating,
switching, controlling, signalling and
monitoring. Laid additionally to the
power supply network, information
transmission is via a bus line suitable for
all specific applications. This electronic
control system does not require a central
unit as it is located decentralized in
every individual appliance. All consumers
connected to this mutual bus line,
such as switches, sensors, actuators,
displays, control units etc. can exchange
information via this communication
line which can also be compiled logically
for evaluation.
The bus line can be laid in line, star or
tree structure. All devices can be selected
freely and are interactive.
The information transmission can contain
analog functions (temperature,
time, quantity etc.) and digital functions
(yes/no, on/off, light/dark, warm/cold,
long/short, more/less). Dimmer functions
are of course also possible.
The advantages of the KNX System
1. Flexible planning and simple
installation
2. Reduction of 230 V line lengths
3. Reduction of fire load
4. Power saving
5. Fast adaptation and high flexibility
for change of usage
6. Problem-free enlargement
7. Intercommunication capabilities
8. No central unit required
