European Installation Bus - Technical Description
In order that the Installation Bus may be economically implemented in the smallest installation or in the largest purpose made building, the system is hierarchically structured. Simple tasks are accomplished with the smallest unit, the Bus Line itself. On each bus line up to 64 bus devices can be operated. Up to 12 such Bus Lines can be joined together with a Line Coupler to one Bus Area. Up to 15 such Bus Areas can in their turn be connected together by means of an Area Coupler. Beyond this the EIB Installation Bus can be connected with other systems via appropriate interfaces. For more functions an application controller can be installed. These devices offer the user further functions such as:
By allocation of groups of devices to individual Areas their independence is maintained despite their functional linkage.
By means of the hierarchical organization the system is transparently visible for commissioning, diagnosis and maintenance purposes. After beginning with one Bus Line at first installation, increasing requirements are met by stepwise expansion. The EIB European Installation Bus can be extended up to 12,480 bus devices.
The EIB Installation Bus permits the realization of manufacturer independent solutions. Often in residential or functional buildings the operational status of the various device groups should not only be recorded but also signalled and displayed. Above all this applies to-.
The EIB Installation Bus is used multifunctionally: all displays, signalling, operational and monitoring elements can be received as information via the Bus Line, and commands and messages can be sent to all other bus users. Thus sensors can be multiply used. This leads to transparent installations and cost savings.
In practice this means that the lighting can be controlled over the same Bus Line as that on which information for monitoring in and outside the building is transmitted, as for example-.
The interaction between signal transmitter and signal or display can be freely configured by the flexibility of the bus technology, as for example in the case of usage alteration or by defining new signalling data.
The bus devices can be installed as rail mounted devices into distribution boards, as flush or as surface mounted devices or as in-built devices directly into an end product (example: luminaires). Further more they can be concealed in cable trunking systems etc. They are available in special designs to suit specific applications. All these devices are connected with each other via the EIB Installation Bus. The Bus Coupler and the terminations for the Bus Line are accommodated in the wall box. The end-equipment (user equipment), e.g. adapter with push-button, is attached to the Bus Coupler. A socket outlet is remotely switchable using a flush mounted a U-Bus Coupler and a connection adapter.
The placing of bus devices can be optionally adapted to the requirements of the installation, so that optimal use of all components is always guaranteed. Devices mounted in distribution boards are connected to the bus via the data rail which fit onto the DIN rail. By snapping the devices onto the DIN rail contact is automatically established between the device and data rail. control is adapted simply and flexibly without intervention in the existing wiring. Installations with the bus, can be adapted for additional requirements by the connection of further equipment to the existing network. Building transparency-.
Over and above the EIB Installation Bus offers the possibility of monitoring and switching lighting and blind installations from a central point. In contrast to conventional solutions this is easily achievable.
