what is a vi in labview
LabVIEW is the emerging standard in visual programming based instrumentation control systems. LabVIEW is programmed with a set of graphical icons (called G) which are connected with wires. The combination of a DAQ board and LabVIEW software makes a virtual instrument or a vi. A vi can perform like an instrument and is programmable by the software with the advantage of flexibility of logging the data that is being measured.
