Introduction - What is C-Bus?

C-Bus is a microprocessor-based control and management system for buildings and homes. It is

used to control lighting and other electrical services such as pumps, audiovisual devices, motors,

etc. Whether it’s simple ON/OFF control of a lighting circuit, or variable (analogue) type control, such

as electronic dimmable ﬂuorescent ballasts, C-Bus can be used to easily control virtually any type of

electrical load.

To ensure fast and reliable operation, each C-Bus device has its own in-built microprocessor and

“intelligence”, allowing units to be individually programmed.

C-Bus uses a patented method for updating the status of units. This method does not require a

central computer or central controller to handle databases or look-up tables to operate. The status

of each C-Bus unit is initiated at speciﬁc time intervals, without the need of a central controller. Each

device is allocated a speciﬁc time frame to broadcast its status, synchronised by a self-generated

system clock pulse. This allows large amounts of data to be transmitted in a very small time frame,

effectively and reliably on the network, leading to low processing overheads and low bandwidth

requirements.
