How do I insert sub vi?
You can add the subVI to VIs by dragging and dropping from the Project Explorer or by using the Functions palette >> Select a VI >> navigate to your VI >> click on the block diagram to place the subVI.
How can you create a subVI from an existing VI?
Creating a SubVI from an Existing VI: Create a new VI and construct the following block diagram. Next, Select the section of the block diagram you want to convert and then select Edit»Create SubVI from the Tools menu. The selected section of the block diagram is replaced with an icon for the SubVI.
What is a sub VI LabVIEW?
A SubVi is a stand VI that can be called by other VI. The SubVI is similar to an individual function. Using SunVI is an efficient programming skill in that it allows you to use the same code in different situations, and make your main VI program clear and compact.
How do I use a subpanel in LabVIEW?
LabVIEW Subpanel
- Assign VI Name to a Button or Tree Item.
- Insert File Name into the Relative Path containing VIs to show in the Sub Panel. See Notes.
- Open a reference to the VI.
- If the VI is in the Idle state then run the VI.
- Insert VI into the Subpanel via a reference.
How do you save sub VI in LabVIEW?
Re: save as subVI Before you save the VI, you need to right click on the icon on the upper right hand side. There you can modify the icon and select the input and output associated with the VI. Once you do it, you just use the VI and connect the various I/O.
How do you call subVI in LabVIEW?
The steps to call a subVI dynamically within an executable is:
- In your SubVI: click File>>VI Properties>>Windows Appearance>>Customize and check “Show front panel when called”. (
- In your calling VI: wire the name of your VI as a file path constant to the Open VI Reference.
How do I save subVI in LabVIEW?
What are the advantages of sub vi?
You can also use a subVI to make your block diagram more manageable. A good rule of thumb to follow is to keep your block diagram no larger that a single screen. Having to scroll back and forth over several screens makes the diagram harder to modify and debug. Using subVIs, your diagram is smaller.
How do I create a global variable in LabVIEW?
Creating Global Variables Select a global variable, shown as follows, from the Functions palette and place it on the block diagram. Double-click the global variable node to display the front panel of the global VI. Place controls and indicators on this front panel the same way you do on a standard front panel.
How do I save as subVI?
How do I save SubVi in LabVIEW?
How do I call a SubVi in LabVIEW?
Re: Call a SubVi in Labview To just have a button in the Main VI. By pushing the Button, the SubVi will come on.
What is the difference between local and global variables in LabVIEW?
Global variables are built-in LabVIEW objects. You can use variables to access and pass data among several VIs that run simultaneously. A local variable shares data within a VI; a global variable also shares data, but it shares data with multiple VIs.
What is functional global variable in LabVIEW?
A Functional Global Variable (FGV) is a frequently used design pattern. An FGV is a non-reentrant VI featuring a while loop that iterates once, and has an un-initialized shift register. The purpose of this construction is to retain data between consecutive calls to the FGV.
How do I save subVI in Labview?
How do I create a global variable in Labview?
How do I create a Fgv in LabVIEW?
Outline
- Initialize the “all stop” functional global variable (FGV)
- Run two subVIs, each containing FGVs.
- Poll the “Stop” button and indicate loop activity.
- Set the “all stop” FGV when the “Stop” button is clicked.
- The two VIs read “all stop” FGV for the loop conditional terminal.
How do I create a subVI in LabVIEW?

What is a sub VI in LabVIEW?
Using sub Vis in LabView is defined as modularity, and by definition, using smaller modules or smaller parts for the overall objective collectively the same tasks as the bigger project will be doing is known as modularity. Creating smaller sections of your overall code is known as a sub VI and in LabView also known as program modularity.
What is program modularity in LabVIEW?
Within LabVIEW, program modularity means creating smaller sections of code known as subVIs. A subVI is similar to a subroutine in text-based programming languages. The power of NI LabVIEW software lies in the modular nature of the VI.
