Soft Pulse Setting: Selecting this setting will automatically define scripts
based on the pulse settings defined in the GUI. This offers a convenient
alternative to learning the script tool if you only need to generate a pulse
output.
Pulse Setting: This mode offers a deterministic output with an offset and
duration synchronized to the incoming trigger. In this mode, the output will
pulse IF the result is TRUE and the total inspection time is less than the
pulse offset from the trigger. If the pulse offset is too short, BOA Spot will not
generate a pass pulse even if the inspection passes. In this case, BOA Spot
will always generate a FAIL pulse if FAIL is selected on any output. This
would result in false rejects if the output is being used to control a directional
device.
Min Pulse Offset = Exposure Time + Acquisition Time + Inspection Time
Example: Pulse 10 ms on GPO0 for a PASS result OR pulse 30 ms on
GPO1 for a FAIL result. Sensor exposure time is 9 ms, acquisition time is
~16 ms and inspection time is ~35 ms. Minimum Pulse Offset = 9+16+35=60
ms. IF the minimum offset is satisfied, BOA Spot will output a PASS pulse on
a good result, ELSE BOA Spot will output a FAIL pulse instead. The duration
of the pulse is not significant in this decision. However, setting the pulse
longer than the trigger period is not advised.
duration is 16
Note: Processing overhead can also affect the minimum pulse offset
requirement. It is good practice to calibrate this time based on your typical
expected usage of the system (i.e. inspection time overhead + system
access overhead)

BOA Spot offers a basic scripting tool for application control. If you are setting
up a complex inspection (not typical with BOA Spot) or handshaking with
connected devices, the script tool provides a lot of flexibility.
You do not need to use the script tool for basic applications. Refer to the on-line
help for more details.
