Abstract

A method for detecting errors in a transfer of data from a transmitter to at least one receiver includes coding the data together with address information identifying the receiver in a series of data packets and transferring the data and the address information using the data packets. The method also includes generating, at the transmitter, a check value for each data packet and transferring the check value with/in the data packet to the receiver. The method further includes comparing, at the receiver, the check value with an expectation value, wherein an error is detected in the event of a deviation. For each data packet to be transmitted, the method includes calculating a number sequence value from the address information using a first calculation rule, generating the check value from the sequence value using a second calculation rule and transmitting the data packet with the check value to the receiver.
