The Compare function allows users to create a ‘fingerprint’ of their machines by saving the data from a selected time period a to create a baseline data set from existing machine data, for statistical comparison with data from other time periods. The function provides a comparative analysis of machine performance over time, and can be found under Remote Monitoring > Compare.
Compare – Actions
Creating a New Baseline Data Set and Running a Baseline Statistical Analysis
- Select the desired machine from the drop-down selection menu at the top of the page.
- Enter a name and description for your baseline data set.
- Choose a start date and time, and an end date and time for your machine baseline data. You can use the calendar data selection tool by clicking on the symbol.
- Check or un-check the box Compute statistics above minimum production speed. This will enable or disable the feature when creating your baseline, respectively.
- Check or un-check each data variable (data point) from the selected machine which you would like to have included in the baseline.
- Click Calculate to generate statistical baseline analysis values for each of the selected data points (a confirmation window may appear, click OK). The page will re-load to populate with the results of the statistical analysis of each point in the baseline data set.
- Clicking Save will save the baseline data set, and take you back to the main Compare page where the saved item will appear in a list along with other saved baselines on the selected machine.
- You can click the back arrow to cancel without saving any changes or results.
After clicking Calculate, each selected code will include each of the following values:
- Minimum, lower quartile values
- Median value
- Upper quartile and maximum values
- Standard deviation
- Sample size
Comparison Analysis of Baseline with a Different Time Period
Compare Test Data Set from Different Time Period with Baseline
All data set comparison results are displayed with a box-whisker plot of the baseline data side-by-side with the test period data. The line across the inside of the box is the median value. You will always see the baseline values in a table listed above the test values, alongside the graph for each plotted data point. A sample data set for machine speed is displayed below.
