Abstract: A method for transmitting data packets between two communication modules via a transmission medium interconnecting the two modules. To transmit a high-priority data packet in real time via the transmission medium, without causing erroneous transmissions of other packets, it is provided that, for an ongoing transmission of a first data packet, a transmitting communication module embeds a second data packet, which is to be sent urgently, directly into the ongoing first packet, buffers a remainder (not transmitted yet) of the first packet and transmits the remainder of the first packet after transmitting the second packet, and a receiving communication module buffers a beginning of a received first packet, receives the second packet and forwards it for further processing, and receives the remainder of the first packet after receiving the second packet, connects it with the buffered beginning of the first packet, and forwards the complete first packet for further processing.

Abstract: In a system and a method for real time transmission between modules that are serially connected to one another, each module embeds its useful data in a data packet received by a preconnected module, which has a data packet number, if a comparison value formed as a function of the data packet number agrees with an identification number (frameID) that is provided in the module.
