摘要： The invention relates to a method for logging messages on a data bus and temporarily storing the sent messages in a cyclically overwritable volatile storing means. The temporarily stored messages can be examined in a targeted manner for attributes of interest by using a verification program. A storage of the temporarily stored messages in a non-volatile second storing means can be initiated by means of definable trigger events that, for example, are formed from individual or a number of attributes of the messages. To this end, the occurrence of the defined trigger event is determined by a monitoring unit, and the data content of the volatile storing means are subsequently transferred into the storage locations of the non-volatile storing means. The principal advantage achieved with the above method resides in the possibility of backtracking the bus traffic. The exchanged messages may be backtracked and thus provide for the possibility to determine from which process and from which control device was the error message sent on the bus. This assists in a decisive manner in the error-seeking in complex communications networks. By means of the backtracking of the error message or with the analysis as to which message has eventually triggered an error in the communications network, it may be ascertained which process is responsible for the error and which program step triggered it. The error-seeking in the software programming of complex control device combinations is thereby decisively facilitated.
