APPLYING PLC AND WINCC TO CONTROLLING AND SUPERVISING CONCRETE MIXING PLANT

Abstract

By the progress of national industry, there are more and more programmable logic controllers (PLC) having a diversity of kinds and variety of technical functions on over the world as well as in Vietnam. More companies and factories in Vietnam such as: pharmacy, making sugar, paper, cement,… all use PLCs in automation systems. The application of SCADA for supervising and controlling the whole system is one of the most essential tools for companies to control the system. This paper introduces application of PLC and WinCC for monitoring and controlling automatic concrete mixing plants, which doing many things: formulation of concrete, transport, quantitative, mixing materials, concrete discharge into tanker.
