Fire Software-Triggered Timing Source (G Dataflow)

Last Modified: January 9, 2017

Fires a software-triggered timing source.

The internal tick counter of the Timed Loop advances by number of ticks when Fire Software-Triggered Timing Source executes. If the internal tick counter jumps past one or more Timed Loop periods, the Timed Loop regards those periods as missed periods. If you want to trigger multiple Timed Loop iterations with a single call to Fire Software-Triggered Timing Source, configure the mode of the Timed Loop to process data that becomes available during missed periods.

Programming Patterns

Use Create Timing Source to create a software-triggered timing source.


trigger ID

The numeric identifier of the software-triggered timing source. The valid range of trigger ID values is 0-127. Because this input is an integer rather than a string, it is safe to use this node in time-critical code.


number of ticks

Number of ticks to increment the internal tick counter of the timing source.

Default: 1


error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: No error


trigger ID out

trigger ID unchanged.


error out

Error information. The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported
