System and communication method for the transmission of event-triggered Ethernet message and trigger time

摘要

It is to be understood relates to a communication method for transmitting the Ethernet messages in a distributed real-time system, where, for example, each of at least the present invention, a network node multiple computers, communication controller of one (121, 122 , and is linked via a communication system having a communication channel number (109) one or more, and a 123, 124), the network node computers four (111, 112, 113, 114) is one intelligent star coupler many (101, 102) are arranged in each communication channel more or Tsu. In accordance with the present invention, the distinction between (ET message) Ethernet messages by time trigger (TT message) Ethernet messages conventional is made, TT message priori between the transmitter and receiver When there is a time conflict between the TT message ET message to be transferred to a (Δ) delay time constant TT message and is transferred to a (Δ) delay time known constant such transfer of messages ET conflicted to be able to be canceled or delayed. Furthermore, the present invention relates to a star coupler for a communication system such communication system and corresponding.
