digio.trigger[N].wait Replace N with the number of the digital I/O trigger line: 1 to 14.
Function Waits for a trigger.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage
triggered = digio.trigger[n].wait(timeout)
timeout
Specifies the time-out value in seconds.
triggered
A customized variable that stores the value
true
if a trigger is detected or
false
if a trigger is not
detected during the time-out period.
n
The number of the trigger line.
Remarks • This function waits up to the
timeout
value in 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 immediately returns. After waiting for a
trigger with this function, the event detector is automatically reset and rearmed. This is true
regardless of the number of events detected.
Details See Interactive triggering in Section 10 .
Also see
digio.trigger[N].clear
Example Waits up to three seconds for a trigger to be detected on trigger line 4, then displays if the trigger was
detected:
triggered = digio.trigger[4].wait(3)
print(triggered)
Output:
false
A trigger was not detected.
true
A trigger was detected.
digio.writebit
Function Sets a digital I/O line high or low.
TSP-Link
accessibility
This function can be accessed from a remote TSP-Link node.
Usage
digio.writebit(n, data)
n
The digital I/O line number (1 to 14).
data
The value to write to the bit; 0 (low) or 1 (high).
Remarks • If the output line is write protected, via the
digio.writeprotect
attribute, the command will
be ignored.
• The
reset
function does not affect the present state of the digital I/O lines.
• Use the
digio.writebit
and
digio.writeport
commands to control the output state of
the synchronization line when the trigger mode is set to
digio.TRIG_BYPASS
.
Details See Controlling digital I/O lines in Section 8 .

digio.readbit , digio.readport , digio.trigger[N].mode
Example Sets digital I/O line 4 low (0):
digio.writebit(4, 0)
