Abstract: The invention relates to a communication system having a communication bus, a master device, which is connected to the communication bus and which communicates with the communication bus in a master mode, and several slave devices which can be connected to the communication bus and which communicate with the communication bus in a slave mode. To improve the performance capability of the communication system, the slave devices can be connected to the communication bus using a communication module designed as a proxy, wherein the communication module is connected to the communication bus using an input port and output ports for connecting the slave devices using a point-to-point connection, the communication module has a communication processor connected on the input side to the communication bus and on the output side to a first internal bus by means of a first serial interface.

Abstract: A method and a system for recording, synchronizing and analyzing data transmitted between spatially distributed devices of a communication network using spatially distributed analysis devices, wherein the data are received by at least two analysis devices looped into the communication network, and wherein the received data are marked by means of a synchronization signal which is simultaneously received by the analysis devices. In order to simplify the recording, synchronization and analysis of data by means of spatially distributed analysis devices, provision is made for the analysis devices to store data frames of the received data in data files, wherein each received data frame is marked with a time stamp of a local time of the receiving analysis device, and wherein time synchronization events are produced by means of the received synchronization signal in each of the analysis devices.

Abstract: The invention relates to a method and a system for recording, synchronizing and analysing data transmitted between spatially distributed devices (56, 78, 80, 58) of a communication network (60, 62), such as a real-time Ethernet network, by means of spatially distributed analysis devices (72, 88), wherein the data are received by at least two analysis devices (72, 88) looped into the communication network (60, 62), and wherein the received data are marked by means of a synchronization signal which is simultaneously received by the analysis devices (72, 88).

Abstract: The invention relates to a communication system (KS), comprising a communication bus (KB), a master device (MD), which is connected to the communication bus and which communicates with the communication bus (KB) in a master mode, and several slave devices (SD1, SD2, . . . SDn), which can be connected to the communication bus (KB) and which communicate with the communication bus (KB) in a slave mode. In order to improve the performance capability of the communication system, the slave devices (SD1, SD2, . . . SDn) can be connected to the communication bus (KB) by means of a communication module (KM) designed as a proxy, wherein the communication module (KM) is connected to the communication bus (KB) by means of an input port (EP1) and has output ports (AP1, AP2, . . . APn) for connecting the slave devices, (SD1, SD2, . . .
