NI VeriStand natively supports Analog I/O and Digital I/O functions with the following types of NI DAQ devices:
- Multifunction I/O (MIO) like the NI 63xx, NI 62xx, NI 61xx and NI 60xxE
- Counter/Timer (TIO) like the NI 66xx
- Digital I/O (DIO) like the NI 650x, NI 651x, and NI 652x
All native NI-DAQmx I/O (excluding custom devices or other custom implementations) is in the form of single-point reads except for Analog Input, which can be acquired as waveforms for logging and UI purposes. Finally, more information on supported hardware can be found at VeriStand NI Hardware Support.
For optimum performance, use hardware that supports Hardware-Timed Single Point Sampling Mode. A list of this hardware can be found at Does My DAQ Device Support Hardware-Timed Single Point Sampling Mode?. If your hardware does not support Hardware-Timed Single Point Sampling mode, you can disable this feature in the Device Specification Page within the System Explorer (as shown below):
Note: VeriStand 2010 and greater supports Hardware I/O on both PC and Real-Time targets. However, VeriStand 2009 only natively supports hardware when deploying NI VeriStand to a LabVIEW Real-Time Target.
