Teaching by means of remote access to models

The basis of modern teaching in subjects Programmable Logic Controllers and Computer Control Systems is students´ practical work with models operated by PLCs (programmable logic controllers) or by industrial computers (IPCs). To enable students to work with the models outside laboratory lessons as well, a web interface with a system of booking is created and with its help it is possible to access and control models with a virtual PC for some time. By the access via a remote desktop the virtual PC can control and thus program a given model. Currently it is possible to work with these models: a model of liquid level stabilization, a model of a railway traffic, a model of a ball on an inclined plane, a model of synchronous axes of electric drives and a model of temperature control. Students can carry out remote access to control elements of individual models both in the laboratory and outside the college. Webcams are connected to each model, allowing to monitor the activity of the models. There are instructions and tasks with increasing difficulty prepared for the work of students in seminars. The authors are of the opinion that it is in the field of mechatronics is didactic reasons very important to allow students to practice professional physical models and management with the latest technologies - Internet-programmable computer control systems.
