The monitoring and control systems for the real equipment controlled by PLC in education

Abstract

This paper is focused on education in the field Measurement and control of technological processes. In one part of this field students obtain theoretical knowledge in an application of commercial systems for measurement, visualisation and control of technological processes. The data are measured by a programmable controller (PLC) and as the superior systems the system InTouch, Wizcon and ContolWeb2000 were used. All systems were tested on the real equipment. The programmable controller controls the surface of two communicating vessels and at the same time is a data source for master applications that are designed for the systems InTouch, Wizcon and ContolWeb2000. The contribution also describes visualisation systems and serial communication for Windows and gives the description of the ModBus protocol.
