Abstract: In this paper we proposed to develop an experimental set-up of PLC and SCADA based mixing and control of Continuous Stirred Tank Reactor (CSTR). The set-up automatically monitors different parameters with the help of SCADA HMI. The PLC is connected to the level sensors and solenoid valves are controlled based on the level in the tank reactor. This model also has the stirrer control unit which continuously stirrers the reactor and mix the reactants. The PLC used is Allen Bradley Micrologix 1200 and the SCADA software is RSView32. Thus the level in the CSTR is constantly monitored and brought to a constant level as required for the operation. The automation is further enhanced by constant monitoring using SCADA screen which is connected to the PLC by means of RS232 communication cable.
