digio.trigger[N].wait()
This function waits for a trigger. This function is not available on the Models 2604B/2614B/2634B.
Type TSP-Link accessible Affected by Where saved Default value
Function Yes
Usage
triggered = digio.trigger[ N ].wait( timeout )
triggered The value
true
if a trigger is detected, or
false
if no triggers are detected during
the timeout period
N
Digital I/O trigger line (1 to 14)
timeout Timeout in seconds
Details
This function pauses for up to
timeout
seconds for an input trigger. If one or more trigger events are detected
since the last time
digio.trigger[ N ].wait()
or
digio.trigger[ N ].clear()
was called, this function
returns a value immediately. After waiting for a trigger with this function, the event detector is automatically reset
and ready to detect the next trigger. This is true regardless of the number of events detected.
Example
triggered = digio.trigger[4].wait(3)
print(triggered)
Waits up to three seconds for a trigger to be
detected on trigger line 4, then outputs the
results.
Output if no trigger is detected:
false
Output if a trigger is detected:
true
