INDUSTRIAL AUTOMATION USING PLC, HMI AND ITS PROTOCOLS BASED ON REAL TIME DATA FOR ANALYSIS

Aim of this study is to resolve the automation and control issues in Indian industry with low cost control and effective data analysis for industrial automation. The objective of study is to take the overview of industrial automation need for present Industries requirement with advance communication facility, record generation for report analysis as well as visualization of information & utilization of advance VFD function to reduce the use of mechanical system and optimize the energy for manufacturing & increase the operation flexibility. In this investigation a new concept is implemented wherein, user can monitor the data and control the data remotely using web access in mobile or else from location where user is located. Also data can be analyzed as per date and time of log in excel format otherwise through email directly. In this study, the concept of PLC (programmable logic controller), HMI (human machine interface), energy measurement device, VFD (variable frequency drive), induction motor, data logging are studied. the interface of PLC, HMI, VFD & measurement device was done into various protocols like rs-232, rs-485, etc. Here, VFD is used for controlling the speed of induction motor using analogue output of PLC. The PLC is used for ladder logic development. HMI is used to monitor a variety of parameters of energy measurement device, like speed, direction & operations of induction motor. Analysis is conducted by data logging of parameters like voltage, current, power, along with HMI display. The input – output status is also shown in display for diagnosis purpose. The report is generated in excel format which is stored in pc drive or USB. This report is useful for future analysis which increases the productivity of the system. In this study of advance technology the researchers have done analysis and monitoring of the data using web as well as in mobile application.
