A supervisory tool for real-time industrial automation systems

Object-oriented techniques have been increasingly used during the development of real-time industrial automation systems, both in modeling and simulation frameworks used in problem domain analysis and requirements engineering, as well as for implementing SCADA (Supervisor.), Control And Data Acquisition) systems. However, mostly commercial available CASE (Computer Aided Software Engineering) tools do not supports the automatic code generation for SCADA systems. This paper proposes an architecture for integrating supervisory tools into object-oriented frameworks for industrial automation applications. The ideas proposed have been implemented and integrated with an object-oriented framework for real-time industrial automation applications. Real case studies have been developed, including the supervisory control of a chemical plant's prototype and the development of man-machine interfaces for food industry (pork processing plant).
