Supervision of control valve characteristics using PLC and creation of HMI by SCADA

The system introduced here is an experimental study which helps in controlling the characteristics and ON/OFF states of a control valve. A graphical user Interface has been developed using supervisory control and data acquisition (SCADA) and the programming of the control system has been done using programmable logic control (PLC). A descriptive study has been incorporated in this paper to formulize all factors responsible for the change in valve characteristics. This system gives a clear idea about the opening and closing of three types of valves which may be present as per its requirement in an industry. The user of the system is able to supply input parameters so as to efficiently control the valve. The system is highly efficient and cost effective, as only one interfaced digital system along with a PLC can control many subsequent valves.
