The VI makes temperature measurements and displays them in the thermometer indicator and on the chart. Temperature System Demo.vi simulates a temperature monitoring application. You can press it to abort program execution. Notice also that the Abort button becomes active in the Toolbar. Other buttons on the Toolbar may also change appearance (or disappear) because certain buttons are only applicable while the VI is running (such as the Abort button), and others are only applicable while the VI is not running (such as those used for editing). The Run button will change appearance to indicate that the VI is running. Run the VI by clicking on the Run button, located on the VI's Toolbar (the Toolbar is the row of icons beneath the VI's menubar). To open an example, select Open VI and choose the one you want.įigure 1.8 Temperature System Demo.vi front panel After launching LabVIEW, a dialog box will appear. Make sure you can access the EVERYONE directory from the CD or your hard drive, as described in the Preface it contains the activities for this book. Whether you are using the Professional, Full, or Evaluation version of LabVIEW, just launch it. Generally, however, it's easier to find examples by using the NI Example Finder feature as just described.
The Temperature System Demo example in particular would be located at C:\Program Files\National Instruments\LabVIEW\examples\apps\tempsys.llb\Temperature System Demo.vi. So the examples directory is at C:\Program Files\National Instruments\LabVIEW\examples. For example, on Windows, LabVIEW is usually installed at C:\Program Files\National Instruments\LabVIEW. You can also access all the LabVIEW example VIs directly in the examples directory inside your LabVIEW installation directory. The previous steps are the process for quickly loading example VIs that come with LabVIEW.
