Device for building automation, has functional modules that posses bus interface aligned over serial data bus for data transmission, where functional modules have supply interface separated from bus interface

摘要

The device has functional modules (8,9,10,11) that posses a bus interface aligned over a serial data bus (23) for data transmission. The functional modules have a supply interface separated from the bus interface. The bus interface is aligned at the bus side for processing digital bus signals, whose time structure corresponds to the time structure of digital bus signals of a transmission protocol, whose analog bus signals allow the transmission energy and data by the serial data bus.
