DAQmx Global Channel Filtering

NI-DAQmx Name Control

DAQmx Global Channel Filtering

  • Control Type—Changes the control to a DAQmx task name control.
  • Allow Undefined Names—Allows you to enter an arbitrary string, such as a list of channels or a channel you created programmatically rather than through MAX.
  • Show Invalid Names—Show names of improperly configured channels. Common causes of an invalid channel are not saving the channel or removing the associated device from the system.
  • Allow Multiple Names—Allows you to select multiple channels in the Browse dialog box by pressing the <Ctrl> key or the <Shift> key when you click channel names.
  • Include "New..." Option in Browse—Adds a Create New button to the Browse dialog box.
  • Limit to Device—Place a checkmark in the checkbox and select a device name to show only channels from that device. Select Browse to select multiple devices.
  • I/O Type—Select from All, Analog Input, Analog Output, Digital Input, Digital Output, Counter Input, or Counter Output to list only those types of channels.
  • Project Filter—Select from Display All, Display Project Items, or Display MAX Items to list only those global channels created in LabVIEW Project, MAX, or both.
    Note  If you filter global channel names outside the context of a LabVIEW project, Display All and Display MAX Items only show global channels created in MAX. Display Project Items displays an empty list.

    If you filter global channel names within the context of a LabVIEW project, global channels created in MAX which share the same name as a project-based global channel will be disabled and appear grayed out in the list.
