SOFTWARE AND HARDWARE COMPLEX OF CONTROL OBJECT BEHAVIOR SIMULATION DEVELOPMENT

Abstract

The subject of the study is the process of the stand-simulator structure creation, simulation models of industrial automation objects behavior. The purpose of the article is a hardware-software complex of the sparkling water automat behavior simulation. Tasks: description of the algorithm for obtaining information about the control object building; analysis of the control object structure and functions to construct a simulation model of its behavior; synthesis of solutions of hardware and software complex. Applied methods: theory of algorithms, methods and models of object evaluation, theory of multifactor experiment, programming of programmable logic controllers. The results: the main problems that emerge with creating solutions for automation of industrial facilities are described; a list of input-output signals of the sparkling water automat was created; using this list the equipment to create a hardware and software complex was chosen; software package that consists of two modules: using a programmable logic controller, and SCADA-system were developed Conclusions: To create an object simulator using programmable logic controller, information of input-output signals is required. This information is based on the results of the control object behavior description. It is found that the list of signals of simulator is the opposite of the control object signals list. The usage of the developed program control object simulator gives benefits like decreasing of the object functionality testing time, increasing speed of eliminating bugs in the program, ease of testing after adding new functionality.
