Overview

ABSTRACT

The G language, compiled and of rapid execution, is perfectly suitable for the acquisition, treatment and signal output operations of control-command applications. This article specifically presents the usage of the LabVIEW software, which allows for generating data acquired or transmitted in relation to physical processes. The integration of "smart "components such as the DSP or the FPGAs has made the control of these processes stricter. The latest version of the LabVIEW software provides the necessary tools for the recent technology using parallelism and Wi-Fi communication. These aspects, via the USB, LXI or PXI connections, have greatly improved the performances of the command.

 INTRODUCTION

This section follows on from [S 8 205v2] . In this section, we focus on the use of LabVIEW software to manage data acquired or supplied in relation to physical processes. Thanks to "intelligent" components such as DSPs and FPGAs, the control of these processes has become more demanding and rigorous, accompanied by more complex mathematical analyses. And control is more efficient, especially where boards have been developed to enable "real time" and "parallelism" via USB, LXI or PXI links.

Finally, industrial applications will be discussed, highlighting a number of control devices.
