WEB BASED ONLINE MACHINE CONTROLLING ANDMONITORING USING PLC VIA MODBUS COMMUNICATION

Abstract

In this modern world, the industrial sector has been shifted from the classical methods of control and automation all the industrial sectors are moving towards Automation and Control to the state of art technique. This turned the industrial sector to reach high growth and production. Over the past, Ethernet is used for communication with the microcontroller. But it caused collision/traffic in data compression while transferring data and also it is not suitable for real-time application. In the proposed system, PLC (Programmable Logic Controller) with MODBUS (Modicon) protocol is used to overcome those issues. The machine is controlled with the PLC and VFD (Voltage Frequency Drive) alerts the user when a fault arises. The data is controlled and monitored through a webpage and the webpage is developed using SQL YOG. Reliable transmission of data is achieved and process/target completion will be indicated automatically. Real-time applications are continuously monitored anywhere at any time and problems are easily diagnosed using the web. The system developed will be efficient and well secured.
