CONTROLLING AND SUPERVISING THE MIXING SYSTEM USING PLC S7-1200 AND WEBSERVER

Abstract

Today, raw material mixing systems are very popular in factories and manufacturing enterprises: cement, food processing, fertilizer,. . .The system of raw material mixers, in meeting that demand, must ensure the quality of the products. The objective of this article is to program the raw material mixing station using the S7-1200 PLC in combination with the control and supervising of the mixing and filling system by Webserver. The system performs the work of dividing the rate for each batch of mixing, material supplying, material mixing and extracting finished products. In addition, the author has rebuilt the plant model with a compact scale that suitable for the teaching or professional research purpose. The process of system programming is written on the TIA Portal V13 software ofSiemens agency and is operated on the HMI control screen as well as directly monitored on the Webserver. The results show that the stable running model produces good product, the system is operated and monitored accurately via webserver application designed by the author.
