I am in the process of writing a report and need a couple of sentances telling the reader what a VI is. At the moment i have the following text - To author the software within LabVIEW the programmer assembles block diagrams using logically related components resulting in a virtual instrument (or VI). VIs are self-contained programs that can be integrated into an overall software suite.
I think this is a pretty accurate description but my proof readers dont seem to like it! Does anyone have a nice basic desription of what VIs are or your thoughts would be appreciated on the matter.
How about this... "In Labview, you build a user interfaceby using a set of tools and objects. The user interface is known as the front panel. You then add code using graphical representations of functions to control the front panel objects. The block diagram contains this code. If organised properly, the block diagram resembles a flow chart." The UI & block diagram together form a VI (Virtual Instrument) that may be recursively used in other VI's to build complete applications.
