Method and device for transmitting data on a data line between a central control unit and at least one data processing unit interface of at least one decentralized data processing unit

Abstract

A method, and a system suitable for carrying out the method, transmit data on a data line between a central control unit and at least one data processing unit interface of at least one decentralized data processing unit. During the transmission, in order to request data packets, the central control unit periodically outputs synchronization pulses over the data line to the data processing unit interface, whereupon the decentralized data processing unit transmits data packets to the central control unit. According to the invention, the decentralized data processing unit generates, after the synchronization pulse but before the transmission of a first data packet, an electrical discharge pulse, whereby counteracting an electrical charging of the data processing unit interface by the synchronization pulse.
