Abstract:
1. A method for recording, synchronizing and analyzing data transmitted between spatially dispersed devices within a communications network including a real-time Ethernet network, by means of spatially dispersed analysis units, the method comprising the steps of: receiving the data by at least two analysis units looped into the communications network, marking the received data using a synchronization signal received simultaneously by the analysis units, storing data frames of the received data in data files, marking each of the data frames with a time stamp of a local time of the analysis units, generating time synchronization events simultaneously using the received synchronization data in each of the analysis units, during recording of the data files in each of the analysis units, as pseudo frames between the data frames for later synchronization, coordinating the local time stamp contained in the data frames in reference to the inserted time synchronization events, encoding specific information on the analysis units as additional information in each data frame, and compiling the individual data files received during measurement of the individual analysis units in reference to the simultaneous time synchronization events, so that the data frames recorded by the analysis units are in the correct temporal sequence.
