Subscriber device for a high-performance communication system

Abstract

A subscriber in a communication system (102) for transmitting and receiving data telegrams, wherein a data telegram includes reference data or user data and an identifier. The control of transmitting and receiving data telegrams is based on check data sets (122). A check data set includes an address for the reference data or user data and the identifier of the data telegram, which is assigned to the check data set. A transmission list (120) includes a first number of check data sets. A circuit unit (128) generates, based on a check data set of the transmission list, a data telegram to be transmitted. In addition, a second number (136, 138) of check data sets is provided. An assignment unit (140, 144) assigns a received data telegram to one of the check data sets of the second number of check data sets, wherein the assignment is carried out based on the identifier for the received data telegram.

Description

technical field

[0001] The invention relates to a subscriber unit for sending and receiving data telegrams in a communication system, in particular an Ethernet and / or Real-time Ethernet communication system, as well as a communication system and a communication method. Background technique

[0002] A synchronous and timing communication system with equal interval characteristics is understood as a system composed of at least two user equipments, which are connected to each other through a data network to exchange data or transmit data to each other. Here, the data exchange is periodically carried out at equal intervals of the communication cycle predetermined by the communication clock used in the system.

[0003] The cyclical data exchange in communication systems at regular intervals is based on the fact that all communicating components have a common period or time base. This period or time reference is transmitted by an indicative component (periodic hammer) to the othe...
