tsplink.trigger[N].mode
Replace N with the number of the synchronization line: 1-3
Attribute The trigger operation and detection mode.
Default tsplink.TRIG_BYPASS
TSP-Link
accessibility
This attribute can be accessed from a remote TSP-Link node.
Usage mode = tsplink.trigger[n].mode
tsplink.trigger[n].mode = mode
n The trigger line number.
mode Selects the current trigger mode.
Choose one the following values for mode:
0 or tsplink.TRIG_BYPASS Allows direct control of the line.
1 or tsplink.TRIG_FALLING Detects falling edge input triggers.
Asserts TTL-low pulse as an output trigger.
2 or tsplink.TRIG_RISING If the programmed state of the line is high, the
tsplink.TRIG_RISING mode behaves similar to
tsplink.TRIG_RISINGA. If the programmed
state of the line is low, the
tsplink.TRIG_RISING mode behaves similar to
tsplink.TRIG_RISINGM.
3 or tsplink.TRIG_EITHER Detects rising or falling edge triggers.
Asserts a TTL-low trigger pulse.
4 or tsplink.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 tsplink.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 tsplink.TRIG_SYNCHRONOUSM Detects rising edge triggers as an input.
Asserts a low TTL-low pulse for output.
7 or tsplink.TRIG_RISINGA Detects Rising Edge triggers as an input.
Asserts a low TTL-low pulse as an output.
8 or tsplink.TRIG_RISINGM Edge detection as an input is not available.
Generates a TTL-high pulse as an output trigger.
Remarks • You can express the mode as a number (0 through 8) or you can use one of the
pre-defined constants (see Usage).
• The custom variable mode stores the trigger mode as a numeric value when the attribute is read.
• The default trigger mode for a line is tsplink.TRIG_BYPASS.
• To control the line state, use the tsplink.TRIG_BYPASS mode with the tsplink.writebit
and the tsplink.writeport commands.
Details See Hardware trigger modes for digital I/O and TSP-Link synchronization lines in Section 10,
digio.writebit, and digio.writeport.
Example Sets the trigger mode for the synchronization line 3 totsplink.TRIG_RISINGM:
tsplink.trigger[3] = 8
