Creates a timing source for a Timed Loop. The timing source is based on signals a device generates. The instances of this polymorphic VI correspond to the type of signal to use for the timing source. Wire the timing source out output to the source input of the Input Node of a Timed Loop to use this timing source with that Timed Loop.

Timing sources send ticks to a timed loop. Those ticks determine when the Timed Loop executes. By default, the Timed Loop executes each time it receives a tick from a timing source, but other Timed Loop settings can affect when it executes. For example, if you set period in the Loop Configuration dialog to 2, the Timed Loop executes on every other tick the timing source sends.

Refer to NI-DAQmx 7.4 and Later Single-Point Real-Time Applications for an overview of real-time architectures and applications.

The DAQmx Timing Source properties include additional timing source configuration options.
