Virtual instrumentation for Data Acquisition and remote control

In this paper we present an application, written in LabVIEW, through which it can observe, by means of webcam, the effects of commands placed via TCP / IP. As example, we considered a system of a traffic light intersection. To achieve application is used NI USB6008 module placed behind a Web server in order to simulate and in the future to create the smart grids. Using the capabilities of the Web servers and the LabVIEW software it can be possible to train users into a virtual lab.
