Inputs/Outputs

  • cgenclassrntag.png task in —

    task in is the name of the task to which this operation applies.

  • ci32.png action —

    action specifies how to control the watchdog timer task.

    clear expiration (1)

    Unlock a device whose watchdog timer expired.

    reset timer (0)

    Reset the internal timer. You must continually reset the internal timer to prevent it from timing out and locking the device.

  • 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 completes execution.

  • 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.
