Device for manipulating interface signals

摘要

The device (10) has a slave interface (12) connected to a master interface (22) of a control device (20). A circuit configuration (15) includes a manipulation unit, where data-input signals (DIN-M, DIN-S) and a substitute-data signal are supplied to the manipulation unit that outputs corresponding data-output signals (DOUT-M, DOUT-S). A protocol-relevant interface signal is transmitted to a protocol unit and chosen based on manipulation rules and information when the manipulation unit outputs the corresponding data-input signal or the substitute-data signal as the data-output signals. An independent claim is also included for a control device comprising an interface controller.
