Automation of shell and tube type heat exchanger with PLC and LabVIEW

The paper focuses on implementing the automation of a shell and tube type heat exchanger control system through number of tools such as PLC, SCADA, OPC, LabVIEW and internet. In this paper, PID method is implemented on Allen Bradley Micrologix-1200C PLC. The RSView-32 and LabVIEW as a SCADA has been used for graphically monitoring and controlling. Various performance parameters have been found out from the results comparison with MATLAB and PLC. The improvement in project data analysis is successfully done through the integration of PLC with LabVIEW. The PLC-SCADA-LabVIEW control loop is implemented with the functionalities such as, set point modifications, data logging facility, real time data examination and exportation of data with Microsoft-Excel. For getting the signals from PLC to LabVIEW we have used enhanced conventional SCADA based control system with PLC as well as NI-OPC server extensively. The remote monitoring and control of process parameters is done using LabVIEW web publishing tool or remote panel manager. GSM (Global system for mobile communication) modem has been used for sending the SMS by using LabVIEW (Short Messaging Service) on mobile, if any hazardous situation occurs. The integration of automation can be enhanced further more with android mobile application also with the help of LabVIEW dashboard application.
