Wireless Monitoring & Controlling of Chemical Mixing Plant using PLC & SCADA

Abstract

The purpose of this Wireless Monitoring & Controlling of Chemical Mixing Plant using PLC (Programmable Logic Controller) & SCADA (Supervisory Control And Data Acquisition) project is to integrate a PLC with the SCADA to control a chemical mixing plant by wireless communication. The machine uses various normally open and normally closed contacts, to mix and heat/cool up to three different liquids. The PLC is used to control the various AC and DC inputs and outputs of the plant to achieve the desired preset conditions of the chemical process. The inputs of the plant are used to collect the data from a flow meter and temperature sensors. The SCADA allows the operator to employ additional functions and the integrated PLC provides a variable control for a pressure transducer, heater and mixer.
