Interactive learning in automation and industrial processes -development of a semi-virtual industrial laboratory is a publication aimed at technicians, technologists, engineering students and engineers who work in the areas of automation, mechatronics and electrical engineering, as well as professionals who wish to keep up to date. In this book, a semi-virtual laboratory is proposed and implemented, composed of a virtual plant, a supervisory system, a real plant and a PLC. The virtual industrial plant can be used as a model for the development of a wide variety of plants that emulate real industrial plants, being suitable for teaching automation and control, as well as by companies for training employees or even testing control routines before applying them to the real system. The fundamentals regarding PLC as well as the implementation of the semi-virtual laboratory are detailed.
