Recent advances in web plc for industrial control and automation

This paper presents the review of web-PLC recently developed. In the past, remote monitoring and control of industrial systems and processes had limited application because the control system was not accessible from multiple locations. Modems made it possible to access the control system from different locations, but they are generally restricted to downloading and uploading data files and require a customized interface to access the control system. Embedding the Web server in the PLC ensures the timely flow of information from the factory floor. A web server in the PLC has direct access to this information. At the same time, the built-in Ethernet interface allows this information to be easily shared across the enterprises for faster decision making. A new kind of Nano-10 PLC has all the Embedding Web server features. All the features of new kind of web-PLC have illustrated and a comparative study is made among the different embedded PLC currently available in the market. A small laboratory based project on nano-10 PLC is presented in this paper to understand the features, operation and advantages of web-PLC.
