Last Modified: January 31, 2020

Virtual channels and tasks are fundamental components of NI-DAQmx.

Virtual channels, or sometimes referred to generically as channels, are software entities that encapsulate the physical channel along with other channel specific information—range, terminal configuration, and custom scaling—that formats the data. Tasks are collections of one or more virtual channels with timing, triggering, and other properties.
