Control Panels

Event Log Control Panel Settings

The event log folio control panel allows you to configure the analysis settings for the data sheet and view/access the results. It consists of a Main page, Analysis page and an Other page.

Control Panel Main Page

The Main page of the event log folio control panel contains most of the tools you will need to perform an analysis. It contains the following settings:

Note that when you select the Use OTSF column check box on the Other page of the control panel, the software can analyze only one level at a time.

The System is new on start date check box indicates that the system has never been used before and that the start date you entered is also the same calendar date that the system started operating. This setting affects how the software classifies data when it converts the log entries to failure/suspension data. If the system is new, then the times to first occurrence of every event are considered to be complete data (F) because the exact time-to-event is known. If the system is not new, then the times to first occurrence of every event are considered to be right censored data (S) because the amount of time that the system operated before the observation period began is not known.

Tip: As an alternative, you can enter the start date/time and end date/time of the observation period for each system in a separate window by clicking the Systems Setup icon on the Main page of the control panel. The larger window makes it easier to enter information for several systems all at once. This option is available only if you have selected the Use System column check box on the Other page of the folio’s control panel.

If your system does not operate on a 24/7 basis, you may also want to define the shift schedule of the system so that you obtain accurate calculations for the failure and repair times. (See Set Shift Pattern.)

Folio Tools

The folio tools are arranged on the left side of the Main page of the control panel. These tools are also available from the Event Log tab in the Ribbon.

  Calculate converts the log entries into failure/repair times and then fits distributions to the converted data. In addition, it calculates the total uptime and downtime of the components.

  Set Shift Pattern opens the Shift Pattern window, which allows you specify the days and times when the system is operating.

  Systems Setup is available only if you have selected the Use System column check box on the Other page of the folio’s control panel. It opens the Systems Setup window, which allows you to record the dates/times when you started and stopped collecting event log data for each system and whether it was new at the specified start date.

After the folio has been calculated, three transfer options become available:

  Transfer Life Data to New Folio transfers all of the analyzed time-to-failure and time-to-repair data sets to separate data sheets in a new Weibull++ standard folio.

  Transfer Life Data to Selected Folio opens the Transfer Life Data window, which allows you to choose specific data set(s) to transfer to either new or existing folio(s).

  Transfer to BlockSim is available only if BlockSim is activated on your computer. The Transfer to BlockSim window allows you to export the analysis results as blocks in a new simulation diagram.

Control Panel Analysis Page

The Analysis page of the event log folio control panel allows you to specify how the software will fit a distribution to the failure data and the repair data. It contains the following settings:

Control Panel Other Page

The Other page of the event log folio control panel contains optional settings that allow you to format the event log data sheet.

To save your current settings for all new event log folios, click the Set as Default button. To automatically apply the saved settings to any existing event log folio, click Load Default.
