PID Control of Heating Tank using PLC & SCADA

The paper presents an automatic temperature control system using PLC and SCADA based on proportional-integral-derivative (PID) algorithm to maintain a temperature of a machine that uses a closed loop process control where the box temperature control can be achieved. In this system reactor/tank is heated using heating coil and its temperature is measured by RTD temperature sensor. The accurate control of temperature is the realistic feature of this system .The PLC & SCADA control process parameters with efficient accuracy and the results are found to be satisfactorily.
