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.

Abstract: A method for transmitting data to a data line between a central control device and a decentralized data processing device. Input data of the decentralized data processing device is supplied to a processing unit of the decentralized data processing device in a first resolution. The processing unit carries out a transformation of the input data according to a calculation rule, and transmits the transformed data to the central control device by way of the data line in a second resolution. The central control device is used to determine, in the framework of a configuration of the decentralized data processing device, according to which calculation rule from a plurality of calculation rule, the decentralized data processing device is to carry out the transformation.
