Development of a SCADA System for Temperature Control Using Lab View

Remote monitoring and control of industrial processes is the need of today’s automation industry. SCADA (Supervisory Control and Data Acquisition) system is useful in monitoring, controlling and accessing the performance of remotely situated systems by acquiring and controlling the physical parameters such as temperature, pressure, level etc. This paper describes the design and development of a Lab VIEW based SCADA for temperature control system. Data communication is achieved using the popular Modbus Protocol. Various features like database, data logging, secured login, waveform graphs, trends, history and multi-user functionality are also incorporated. The developed SCADA system will be an independent and indigenous tool since Lab VIEW supports the generation of executable file which can practically run on any computer without having Lab VIEW software package.
