DATA TRANSFER SYSTEM, CONTROL UNIT, AND METHOD FOR TRANSFERRING DATA

A data transfer system having a first control unit and a second control unit, wherein the transfer path between the two control signals is formed at least partially by a two-wire cable, by which a useful signal is transferred as a difference signal between the first control unit and the second control unit, wherein the first control unit has a transceiver and the second control unit has a receiver, wherein a measurement circuit to measure a common-mode component in the useful signal is arranged before the receiver of the second control unit, wherein an error correction circuit is provided, which produces a correction signal in accordance with the measured common-mode component, wherein a compensation circuit is arranged after the receiver, wherein the compensation circuit is designed so the useful signal received by the receiver is corrected by the correction signal.
