Abstract : This study illustrates the significance of a Supervisory Monitoring System which is studied in a LabVIEW environment through the development of Graphical User Interface. There is great emergence towards online and Real-Time process monitoring in process industries to limit human intervention and increase safety for life and resources. LabView being flexible provides a solution to this context that supports Real-Time monitoring and controlling. The developed Virtual Instrumentation system is used to monitor the chemical plant parameters such as temperature, chemical level and provide secure access. Any fluctuation in the parameter of interest is intimated to the industry personnel through web-based reports and alarm indication. A Level Control System is simulated to understand the Liquid Level in a Chemical Plant using a PID control scheme. The developed system is inclusive of a security access system that offers access to the GUI only to authorized persons and any unauthenticated access is notified to the industrial team through email. Henceforth, the system offers functionalities of secured login access, easy reconfiguration, alarm facility during parameter limits for futuristic analysis along a Web-based Report Generation. Compared to traditional instrumentation systems, the performance of Virtual Instrumentation systems is always beneficial which saves energy, resources, manpower and enhances safety.
