G-Bus

All the devices for a G-BUS installation are connected together by a two wire bus (the most common form of installation), thus allowing them to exchange data. The function of the individual bus devices is determined by their project planning, which can be changed and adapted at any time.
• Sensors (e.g. push buttons, wind-, temperature-, movement-sensors)
• Actuators (dimming units, electrical heating valves, displays)
• System devices and components (e.g. Line-Couplers, Backbone-Couplers)
Sensors are the starting point for every action, because they gather information and send it on the bus as a data telegram. This can be information about room temperatures, movements, wind measurements or manually input instructions (Push buttons). Sensors are selected depending on the required application.
Actuators receive data telegrams which are then converted into actions. This can include controlling blinds, dimming lights or controlling heating and air conditioning systems. Actuators are also selected depending on the required application and consist of a bus coupler and an application module with the corresponding application program.
The application program is loaded into the devices together with the project design and commissioning software via a system component called interface (either serial or USBinterface) connected to the PC and the bus. The two-wire installation bus is routed in parallel to the 230 V electrical power supply connects all devices and systems of the household technology together, and transmits all the control signals. It looks the same as the DALI protocol bus.
