Title   Designing Monitoring program of Material handling and sorting system based on PLC               

Abstract

With the rapid changes in science and technology in society today, various types of material handling automation production line of the increasingly high demand, the original production of feeding device, can not meet the current needs of a high degree of automation. Protect the production of security, reliability, lower production costs, reduce environmental pollution, reduce labor intensity and improve product quality and economic benefits, is the enterprise survival and development must face and solve reality. The PLC control system and compared to the traditional industrial control systems, high reliability, strong function, programming is simple, easy and cheap to maintain the advantages of Automatic Loading System is the main control device of choice.

This paper mainly introduces a kind of using the touch screen with S7-200 series PLC Human-machine interface design method,combine programming and implementation of Smart line 700IE touch screen with S7-200 series PLC man-machine interface with a cargo sorting system
