Changing the Value of a Numeric Control or Numeric Indicator

Learn how to change the value of a numeric control or numeric indicator in LabVIEW.

  1. Input the new value in the control or indicator.
  2. Register the new value in any of the following ways:
    • Press the Enter key.
    • Click outside the digital display window.
    • Click the Enter button ().

    While a VI is running, LabVIEW waits until you perform one of these actions to interpret the new values. For example, this behavior prevents the VI from receiving 1 and 13 while you are inputting a desired value of 135.

    Note You can use engineering or System International (SI) notation to format a numeric control or numeric indicator for a value without a complex representation. In this case, to retain floating-point representation, LabVIEW adds any necessary prefixes to the unit stirng.
