Configures the task to start acquiring or generating samples when an analog signal enters or leaves a range you specify.

Inputs/Outputs

  • ci32.png when —

    when specifies whether the task starts measuring or generating samples when the signal enters the window or when it leaves the window. Use window bottom and window top to specify the limits of the window.

    Entering Window (10163)

    Start acquiring or generating samples when the signal enters the window.

    Leaving Window (10208)

    Start acquiring or generating samples when the signal leaves the window.

  • cgenclassrntag.png task/channels in —

    task/channels in is the name of the task or a list of virtual channels to which the operation applies. If you provide a list of virtual channels, NI-DAQmx creates a task automatically.

  • cstr.png source —

    source is the name of a virtual channel or terminal where there is an analog signal to use as the source of the trigger.

    For E Series devices, if you use a channel name, the channel must be the first channel in the task. The only terminal you can use for E Series devices is PFI0.

  • cdbl.png window top —

    window top is the upper limit of the window. Specify this value in the units of the measurement or generation.

  • cdbl.png window bottom —

    window bottom is the lower limit of the window. Specify this value in the units of the measurement or generation.

  • cerrcodeclst.png error in —

    error in describes error conditions that occur before this VI or function runs.

    The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. If an error occurs while this VI or function runs, the VI or function runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

  • igenclassrntag.png task out —

    task out is a reference to the task after this VI or function runs. If you wired a channel or list of channels to task/channels in, NI-DAQmx creates this task automatically.

  • ierrcodeclst.png error out —

    error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI or function produces.

    Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
