In hardware-timed single-point sample mode, samples are acquired or generated continuously using hardware timing and no buffer. You must use the sample clock or change detection timing types. No other timing types are supported.

Use hardware-timed single-point sample mode if you need to know if a loop executes in a given amount of time, such as in a control application.

Because there is no buffer if you use hardware-timed single-point sample mode, ensure that reads or writes execute fast enough to keep up with hardware timing. If a read or write executes late, it returns a warning.

Continuous Pulses (HW Timed Updates) is hardware-timed single point for counter output.
