Starting and Ending the Test
Once all the curves have been added, then the test itself can be started. This involves three steps:
1. Selecting which curves are to be recorded.
2. Starting the application program running on the controller.
3. Starting the Oscilloscope recording.
Selecting which curves are to be recorded
The user can define many curves in the Oscilloscope but it is not necessary to record data for all curves
during each test. Use the checkbox in the "Active" column in the "Curve Selection List" to select which
curves will be recorded. In the example below, data will be recorded only for the "REG_ACTPOS" (actual
position) and "REG_TRACKERR" (tracking error) curves. Data for "REG_COMPOS" will not be recorded.
Note that groups as a whole can be selected or deselected. If selected, then data for the selected curves
within that group will be recorded. If deselected, then the checkboxes for all curves within that group will be
grey and no data will be recorded for any of those curves.
When multiple groups have been defined, then there is a restriction as to which groups may be selected at
the same time. No two groups may be selected at the same time if they are associated with the same
controller and use the same PDO message. If groups have been defined in this way, then selecting one
group will automatically cause the other group to be deselected.
Starting the application program
The next step is to start the application program running on the controller if it is not already running. Do
this by switching to the original APOSS Window and starting the application in any of the normal ways. Then
switch back to the Oscilloscope Window. The "Curve Selection List" should now look something like that
below. Note that the bright green "Status" column indicates that the controller is now executing a program.
Starting the Oscilloscope recording
The final step is to start the Oscilloscope recording. This is done used the
At this point, curve data should start to be recorded and displayed in the Chart Window. This will be done in
real time as the test progresses (for the Free Run Oscilloscope) or after the end of the test (for the Single
Shot Oscilloscope). The Oscilloscope Window should now look similar to that shown below.
