LabVIEW creates controls and indicators for the new SubVI, automatically configures the connector pane based on the number of control and indicator terminals you selected, and wires the SubVI to the existing wires. Next, Select the section of the block diagram you want to convert and then select Edit✼reate SubVI from the Tools menu. The selected section of the block diagram is replaced with an icon for the SubVI. Create a new VI and construct the following block diagram. You can simplify the block diagram of a VI by converting sections of the block diagram into SubVIs. The connector pane allows you to assign terminals on the icon to front panel controls and indicators for the purpose of wiring values into and out of a SubVI.
The icon is what the SubVI will look like on another VI’s block diagram.
#What is labview code#
It allows you to write modules of code that you can wire into your diagrams later. So, what exactly is a SubVI? It is a VI that is placed on the block diagram of a higher-level VI. A SubVI is similar to a subroutine in text-based programming languages. SubVIs are the same as VIs, they contain front panels and block diagrams, but you call them from within a VI. This is the perfect situation to start creating SubVI’s! So many while loops and case structures, that it’s actually bigger than your screen size, so you have to use the scrollbars to navigate the program. You go back to try and correct the problem but are overwhelmed by the mess of wires and blocks. So let’s say you have been working on a complex LabVIEW VI, you finally finish, and you go to test it, but it doesn’t work.
