EIB system can now be used at the
Automation Level
Providers of building services automation systems can now utilize the European installation bus at both the field level and the automation level without implementing engineeringiintensive gateways
Siemens Automation and Drives has announced that European installation bus (EIB) can now be used for automation level applications "Controls for Mechanical Building Services", a technical committee of the Comite Europeen de Normalisation (CEN) recently recognized EIBnet as European draft standard ENV 13321-2 for the building services automation level

While the connection between motor and inverter supply is usually straightforward, there are still a number of issues which need to be carefully considered, as this article explains
The proximity of the EIBnet to the BACnet makes it easy to transfer data from the automation level to the management level.
In building services automation, a distinction is made between three hierarchical levels: the management level, the automation level and the field level.
The EIB was initially developed for the field level with a data signaling rate of 9,600 bit/s.
The EIBnet protocol, developed for the automation level, now makes data transfer via Ethernet 10BaseT possible at a speed of 10 megabit/s.
A simple data transfer from the automation level to the management level is made possible by EIBnet's proximity to BACnet.
At the request of the European Installation Bus Association (EIBA), Siemens A and D's Electrical Installation Technology Division had specified the "EIBnet protocol" for use at the automation level and applied to the CEN for standardization.
As a result, providers of building services automation systems can utilize the EIB at both the field level and the automation level without implementing engineering intensive gateways in their system technology.
At the same time, a transition from EIBnet to BACnet is possible with minimal investment.
EIBnet thus widens EIB's application scope even further.
