| 摘要 |
The invention relates to an apparatus and a process for the data communication between a system unit ( 8 ) and technical facilities ( 2, 3, 4 ) in buildings for the flexible and convenient parameterization and remote monitoring of the facilities ( 2, 3, 4 ), an existing communication infrastructure being usable to reduce the expenditure resulting from cabling and to enable cost-effective data communication. The apparatus comprises a system unit ( 8 ) which is suited for data transmission according to a first data transmission protocol, at least one facility ( 2, 3, 4 ) which is suited for data transmission according to a second data transmission protocol, a protocol converter ( 1 ) which is connected to system unit ( 8 ) and converts data of the first data transmission protocol into data of the second data transmission protocol and vice versa, and a bus system ( 5 ) to which the facilities ( 2, 3, 4 ) and the protocol converter ( 1 ) can be connected.
