INTRODUCTION
In this exercise, you will open and
modify the Temperature Running Average VI you created
in an earlier tutorial. You will add an Overtemp
control that utilizes a Case Structure to indicate
when the current temperature is above a value entered
in a Digital Control on the Front Panel. When the
current temperature goes over the value, a Boolean
Indicator will light and a beeping sound will occur
on the computer's speaker until the temperature goes
below the upper temperature limit.
- Open the Temperature_Running_Average.vi
you created in an earlier tutorial
- Save-As to Temperature_Running_Average_With_Control.vi
- Add and wire components as shown above
- Run the VI Continuously, change the
Upper Limit value and observe the results
- Save the VI
Below are a couple of Block Diagram nodes that
may be new to you:

sounds a beep on the computer's speaker if
the selection terminal of the Case Structure
receives a TRUE
