Examining the Logic in the Run Section
The left branch of the parallel path (1) supports the normal test flow. The right branch (2) exists to support
the Cancel function associated with the If/Else activity (3) that follows the Custom Message (4) activity.
Default behavior
By default, the If/Else (3) and Custom Message (4) activities are disabled. So when you run the test, no
prompt appears to inform you that the test is about the begin, and that you can choose to cancel.
Because of this, when you run the test you are prompted for specimen dimensions per the Input Parameters
activity (5), and then the Test-Run Display tab shows a graph as the Go To + DAQ + Detection activity
performs a ramp. The Go To + DAQ + Detection activity is nested within the Parallel Paths activity (6).
(The Auto Offset and Calculate Variables activities run before the Parallel Paths activity, but do not
affect the interface.)
When a break is detected, the ramp stops and you are prompted to return to zero when the next Custom
Message activity (7) executes.
Behavior with the If/Else and Custom Message activities enabled
If the If/Else and Custom Message activities (3 and 4) are enabled, when you run the test, a prompt
appears to inform you that the test is about the begin, and that you can choose to cancel.
If you choose to cancel, the test logic uses the right side of the Parallel Path activity (2) to skip the ramp
command in the Go To + DAQ + Detection activity nested in the Parallel Paths activity (6). Next, the
Custom Message activity (7) prompts you to return to zero.
