摘要
The invention relates to a method for transmitting data to a data line (12) between a central control appliance (10) and a decentralised data processing appliance (11.1,11.2,11.3). According to the invention, during a normal operation of the arrangement, the central control appliance (10) periodically sends synchronisation pulses (Sync) to the at least one data processing appliance (11.1,11.2,11.3) via the data line (12) in order to request data packets, and the decentralised data processing appliance (11. 1,11.2,11.3) sends the data thereof to be transmitted, as data packets, to the central control appliance (10), following the synchronisation pulse (Sync). The data line (12) is embodied as a data bus. Each of the decentralised data processing appliances (11.1,11.2,11.3) is configured by the central control appliance (10) before the first transmission of data packets to the central control appliance (10). In order to configure the arrangement, a bi-directional communication is carried out between the central control appliance (10) and the at least one decentralised data processing appliance (11.1,11.2,11.3).
