Graphic programming
Unlike text-based programming, in LabView functions are programmed
using graphic function blocks.
The DLL functions required are represented in LabView by calls, with
parameters that can be set, in the related programming language.
There, among other aspects, the related call parameters are defined,
input and output values defined and the connection to the DLL estab-
lished.
