1A. Introduction to C-Bus

2.2 C-Bus Units

All units on the C-Bus network have their own built-in microprocessor, allowing them to operate

independently with “distributed intelligence”. This provides extremely reliable and efﬁcient

communications.

Every C-Bus unit has a unique number, so that all devices on the network can communicate directly.

Also, as C-Bus uses point to multi-point communication, every device on a C-Bus network issues

and responds to commands directly from the network, rather than requiring a central computer or

controller.

2.3 Simple Control

Each C-Bus device is programmed to issue and respond to the certain commands. A virtually

unlimited number of commands can be programmed into the C-Bus system. Generally, input

devices are programmed to issue commands, and output devices are programmed to execute those

commands.

When a C-Bus Group Address command is issued by a C-Bus device, any other devices that have

been programmed with that Group Address will be activated, wherever they are on the C-Bus

network. There is no need for any direct 240 V connection between any C-Bus units.

2.4 Multiple Events

Single devices can also produce multiple events. For example, you may program an input switch so

that the length of time the key is pressed determines what Command is issued – a short press issues

an on/off command and a long press controls a dimming command.

Multiple commands do not have to control the same output device(s), so complex scenarios can be

easily created, for example a single push button switch controlling a whole ﬂoor of a building.

Multiple input devices can conditionally control a single output device, dependant on speciﬁc

circumstances. This allows multiple levels of over-ride switching and other complex control systems to

be created easily.

2.5 Control Flexibility

The C-Bus system can carry out control in virtually unlimited ways:

• any input device can be programmed as a master control point. Master overrides can be

positioned anywhere in the network, and control any other unit or units on any connected

network

• the system can allow unlimited switching congurations. Two, three (or more) switches can be

set to toggle or control any other switch or device

• overrides can be easily re-programmed via Windows software at any time

• a computer or central controller is not required for normal C-Bus operation, but can be used to

add additional features if desired.
