                              Analyze PLC values with the accuracy of PLC cycles, triggered f. E. by a fault occurrence to provide additional support for quick fault tracing and removal
                              
 
 PLC side monitoring and recording of defined signal values for each PLC cycle
                              
 
 Amount of signals and amount of cycles to monitor can be configured
                              
 
 A trigger event is used to stop the monitoring after recording a pre-defined amount of additional cycles
                              
 
 Transfer of monitored cycle values to the SIS PC via fast OPC interface (approx. 30 sec. transfer duration) after the recording has stopped
                              
 
 The SIS PC acknowledges the receipt of the data and enables the PLC side monitoring again
                              
 
 Data is stored with timestamp to the local hard disc for further evaluations
                              
 
 Use the SIS Post Mortem Viewer to comfortable view the recorded values plotted against the PLC cycle no. axis (time)
                              
 
 Select up to 8 signals and view their values in a trend display similar to the Data Logger
                              
 
 Load / save functions for the signal selection
                              
 
 All functions of the Data Logger trend display are available, including a new "Goto Cycle…" function for quick navigation
                              
 
 Print the trend or export the displayed data as text file (CSV)
