Writes samples to the task or virtual channels you specify. The instances of this polymorphic VI specify the format of the samples to write, whether to write one or multiple samples, and whether to write to one or multiple channels.

If the task uses on-demand timing, this VI returns only after the device generates all samples. On-demand is the default timing type if you do not use the DAQmx Timing VI. If the task uses any timing type other than on-demand, this VI returns immediately and does not wait for the device to generate all samples. Your application must determine if the task is done to ensure that the device generated all samples.

The DAQmx Write properties include additional configuration options for write operations.
