![]() ![]() 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. In this example, a commodity PC running an HMI communicates over standard network protocols (such as Ethernet) to field devices such as PLCs. ![]() The remote controlling of process is now much required control to use expert man power. 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 proposed system is made possible by the use of PLC, Microcontroller, GSM modem, Ethernet Module, and other elements. In recent years the development of industrial automation through remote monitoring and controlling has been increased. It will be great benefit if we control the process plant through remote monitoring and controlling. Bishop, Modern Control Systems, Prentice Hall, 2001. ![]() and manage control, automation, and instrumentation systems, components. Understand the purpose of control engineering Examine examples of control systems Understand the principles of modern control engineering. Now a days industry needs accurate automation system. In this paper we have developed a platform to remotely monitor and control PLC-based processes over web and GSM network. Control Engineering connects the global industrial engineering audience through. This paper focuses on Modbus control system using PLC and SCADA.
