Method for transmitting data to a plurality of data stations
First Claim
1. 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 having an address allocated to it under which it receives data and also outputs messages to the central station, and at least two data stations of the plurality of data stations requesting the same data from the central station, comprising the steps of:
- selecting by the central station one data station of data stations that are requesting the same data and communicating the address of the selected data station from the central station to the at least one other data station of the data stations that are requesting the same data;
in response thereto, modifying the address of the at least one other data station to the address of the selected data station;
transmitting data from the central station to the selected data station, the transmitted data also being received by the at least one other data station whereby the transmission protocol is only processed between the central station and the selected data station during the data transmission; and
resetting the address of the at least one other data station after the conclusion of the data transmission.

Abstract
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.
