Data capture about control object and its analysis in real time with minimal delays is an actual problem in the learning process and in many researches. In this article we suggest that the input/output can provide data exchange via digital analogue channels between the Matlab / Simulink field and the industrial control device / control object in two modes of operation. The device is developed with using open technologies and based on a cheap microcontroller AVR, provides a two-way communication channel with the top-level system through popular USB / Ethernet interfaces. There are shown technical solutions of the input and output channels of the input-output device compatible with industry standards.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
