Abstract
A method of transmitting data on a data line between a central control device and a decentralized data processing device. During a normal operation of the system, the central control device periodically sends synchronization pulses to the at least one data processing device via the data line in order to request data packets, and the decentralized data processing device sends the data thereof to be transmitted, as data packets, to the central control device, following the synchronization pulse. The data line is embodied as a data bus. Each of the decentralized data processing devices is configured by the central control device before the first transmission of data packets to the central control device. In order to configure the system, a bi-directional communication is carried out between the central control device and the at least one decentralized data processing device.
