- 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)
