Abstract
The control device has a receiving device, an output stage, a checking device and a reset device. The receiving device is used to receive at least one data block including control commands from a data bus, the output stage is used to output an output signal in response to the control commands, the checking device is used to output an error signal if the at least one received data block is faulty and/or if no data block is received within a predetermined time, and the reset device is used to reset the output stage in a predefined state if the checking device outputs the error signal. The control device is thus able to react automatically to faultily transmitted data blocks without having to wait for return messages from a transmitting central processor unit.
