Trigger Debounce
Trigger Debounce is the ability of the system to accommodate switching noise on a
trigger state change – a common issue with relays that have some intermittent contact
while engaging.
Trigger overruns (when the vision system is triggered faster than the device can process)
can sometimes be avoided by increasing the “debounce” time in the camera definition file
located in the C:\Microscan\Vscape\Drivers\CamDefs directory.
The IO Line Debounce High Time and IO Line Debounce Low Time can be added to the
file as in the example below. Debounce time is 100 μs.
The minimum value for "IO Line Debounce Time" is 0 µs, which disables software debounce
altogether. The maximum value is 268432 µs.
Standard debounce as described for the trigger:
IO Line Debounce High Time 100 //usecs (valid range: 0 to 268432 such that
debounce time * 1000 must be divisible by 16)
IO Line Debounce Low Time 100 //usecs (valid range: 0 to 268432 such that
debounce time * 1000 must be divisible by 16)
