摘要: In a method for transmitting data from a central station to a plurality of data stations via a multipoint connection according to a prescribed transmission protocol, every data station has an address allocated to it under which it receives data and outputs messages to the central station. When at least two data stations request data from the central station, the central station (Z) selects one of the data stations that request data and communicates the address of the selected data station (K1) to the further data station (K2, K3, Kn). In response thereto, the latter modifies its address to the address of the selected data station (K1). The central station (Z) transmits data to the selected data station (K1) that is also received by the further data station (K2, K3, Kn), whereby the transmission protocol is only processed between the central station (Z) and the selected data station (K1) during the data transmission. After the conclusion of the data transmission, the further data station (K2, K3, Kn) resets its address.
