Adding and Configuring DAQ Device Channels

Last Modified: March 27, 2020

Define how VeriStand performs measurements using DAQ channels.

Before you begin, add a DAQ device. Each measurement type has configurable properties. For example, counter input channels that count up have a count edge property that sets whether the channel counts rising edges or falling edges.

Some properties are only available on certain devices. Refer to the documentation for your hardware device to find out what properties your device supports.

  1. Launch the VeriStand Editor.
  2. In the Project Files pane, double-click a system definition file (.nivssdf). System Explorer opens.
  3. Click Targets»Controller»Hardware»Chassis»DAQ in the configuration tree.
  4. Right-click a DAQ device and click Add Channels.
  5. Determine the channel type you want based on the measurement type.
    Measurement type Channel type
    Analog Input (AI)
    Analog Output (AO)
    Digital Input Digital Input (DI)
    Digital Output Digital Output (DO)
    Counter Input (CI)
    Pulse Generation Counter Output (CO)
  6. In the Add DAQ Channels dialog box, use the Select channel type to add pull-down to select the channel type.
  7. Use the Select measurement type pull-down to select the measurement type.
  8. Click Next.
  9. Select the channel(s) you want to add and click Finish.

    If the DAQ device does not contain channels of the type you specified, no channels are available to select.

  10. Save the system definition file.
