Abstract
A method for data exchange via a bus system, wherein an amount of data determined for data exchange is composed of a plurality of data packets, which data packets are to be transmitted in a predetermined sequence from a second participant of the bus system to a first participant of the bus system, wherein, for data exchange, a first data query is sent from the first participant to the second participant, and wherein, as a reply to the first data query, a first data packet is sent from the second participant to the first participant. Especially after the first participant has received the first data packet, a second data query is sent from the first participant to the second participant via the bus system, and as a reply to the second data query, a second data packet is sent from the second participant to the first participant. The second data packet is either the first data packet or a data packet following the first data packet in the predetermined sequence. The first and the second data query contains, in each case, a parameter with a first or a second parameter value, and in the case in which the parameter values of the first and second data query agree, the first data packet is sent, while, in the case in which the parameter values of the first and second data query differ, the data packet following the first data packet in the predetermined sequence is sent.
