Patent ID: 10389806

Abstract:
According to the invention, in order that the asynchronous bandwidth available in a real-time capable Ethernet data network protocol can be better utilized without collision at least one slave (S1, . . . , Sn) which wishes to transmit asynchronous data informs the master (M) in a transmission cycle (Z(m)) by means of a request data packet (DPa) how much asynchronous data this slave (S1, . . . , Sn) wishes to transmit asynchronously and by means of an invitation data packet (DPe) the master (M) informs the slave (S1, . . . , Sn) as to the time (tas) within a following transmission cycle (Z(m+k+l)) at which the slave (S1, . . . , Sn) should transmit the asynchronous data in an asynchronous data packet (DPas).
