Method for automatically processing a number of log files of an automation system

The invention relates to a method for automatically processing a number of log files (P1 to Pn) of an automation system (1) of a technical facility, comprising the following steps: determining at least one message part (N1 to Nn) of each data set (D1 to Dn) of a log file (P to Pn) by concatenating all the contents of the respective data set (D1 to Dn) of the log file (P1 to Pn); summarising the data sets (D1 to Dn) of all the log-1 files (P1 to Pn) in a summary file (SD); chronologically sorting the data sets (D1 to Dn) of all the log files (P1 to Pn) in the summary file (SD); compressing each data set (D1 to Dn) in the summary file (SD); coding the compressed data sets (D1 to Dn) in the summary file (SD) by at least one or more numerical codes (Kx); sorting and allocating the compressed data sets (D to Dn) using the determined numerical code(s) (Kx) to form at least one group (Gy) having an associated group code (KGy); and outputting the alphanumerical message part (N1 to Nn) of the log file (P1 to Pn) by de
