Remote Control Technology Of Web-Based PLC Control System

In the development of industrial automation, more and more people attach importance to industrial control configuartion software which is one of the most important part of automation software. Configuartion software is a kind of special software that is used to collect the on-site data and display the process of production, it is the expansion of computer technology service in industrial field. With the improvement of industrial automation, the demand of production control system is more diversified. Configuartion software reversal of past behaviour, gradually replace the traditional software and adopted by the designer.Wonderware is a developer that design the human interface automation software and configuartion software. In the earlier time , Intouch is geted to be known as monitoring software by china and acquired by the users and applicated widely. Because of this, on the basis of Tianjin 1150mm reversing rolling mill, study the application of Intouch in this project. In the same time, according to the insufficiency of it, put forward the idea that use Intouch as a design platform, make use of the advanced programming language and COM module to redevelop.This paper describes the process flows and the whole system design of the 1150mm reversing rolling mill. Analyze the whole layout of the monitoring system, design the monitoring picture, use access database and language of Intouch to design the function of English– Chinese shift, store the process parameters and inquiry statistics. Introduce how to communicate between Intouch and PLC by using I/O Server, how to carry out data exchange between Intouch and database. At the same time, use Intouch as a design platform, on the basis of COM module, develop the ActiveX module by using advanced programming language, and import it into Intouch, compensate for the insufficient on application.It can be concluded that the monitoring system can guard the production process on-line, exchange data with PLC and other application software. ActiveX module can work well in Intouch and communicate with PLC, the result is satisfactory.
