Development of A web and GSM Based Monitoring and Controlling System for PLC Based Application

In this paper we have developed a platform to remotely monitor and control PLC-based processes over web and GSM network. It will be great benefit if we control the process plant through remote monitoring and controlling. In recent years the development of industrial automation through remote monitoring and controlling has been increased. The proposed system is made possible by the use of PLC, Microcontroller, GSM modem, Ethernet Module, and other elements. The main aim of the remote monitoring and controlling is when a critical failure occurs notifications are generated and send to the expert via SMS and internet message with the help of GSM modem and through internet. The remote controlling of process is now much required control to use expert man power. The challenge here is to establish a proper serial and Ethernet communication between PLC and Microcontroller via appropriate protocol and also to integrate conventional process with recent communication technologies along with advancements in wireless and internet technology.
