digio.trigger[N].EVENT_ID
Replace N with the number of the digital I/O trigger line: 1 to 14.
Attribute Used to identify a specific event.
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage event_id = digio.trigger[n].EVENT_ID
event_id The trigger event number.
n The trigger line.
Remarks • To have another trigger object respond to trigger events generated by the trigger line, set the other
object's stimulus attribute to the value of this constant.
digio.trigger[N].mode
Replace N with the number of the digital I/O trigger line: 1 to 14.
Attribute The trigger operation and detection mode.
Default digio.TRIG_BYPASS.
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage mode = digio.trigger[n].mode -- Reads the trigger mode.
digio.trigger[n].mode = mode -- Writes the trigger mode.
n The trigger line.
mode Selects the current trigger mode.
Choose one the following values for mode:
0 or digio.TRIG_BYPASS Allows direct control of the line.
1 or digio.TRIG_FALLING Detects falling edge input triggers as input.
Asserts TTL-low pulse as an output trigger.
2 or digio.TRIG_RISING If the programmed state of the line is high, the
digio.TRIG_RISING mode behaves similar to
digio.TRIG_RISINGA.
If the programmed state of the line is low, the
digio.TRIG_RISING mode behaves similar to
digio.TRIG_RISINGM.
3 or digio.TRIG_EITHER Detects rising or falling edge triggers.
Asserts a TTL-low trigger pulse.
4 or digio.TRIG_SYNCHRONOUSA Detects the falling edge input triggers and
automatically latches and drives the trigger
line low. Asserting the output trigger releases the
latched line.
5 or digio.TRIG_SYNCHRONOUS Detects the falling edge input triggers and
automatically latches and drives the trigger
line low.
Asserts a TTL-low pulse as an output trigger.
6 or digio.TRIG_SYNCHRONOUSM Detects rising edge triggers as an input.
Asserts a low TTL-low pulse for output.
7 or digio.TRIG_RISINGA Detects Rising Edge triggers as an input.
Asserts a low TTL-low pulse as an output.
8 or digio.TRIG_RISINGM Asserts a TTL-high pulse as an output trigger.
Input edge detection is not available in this mode.
