Abstract: In ancient days, the industrial parameters such as level, pressure, flow, temperature etc are measured and are converted to the actuated variable as required by the associated actuators and final control elements. In all the process industries, among the various controllers, a Proportional, Integral and Derivative (PID) controller is the most widely used controllers because of their robustness, easy implementation reduction of error for current, past and future disturbances which might arise in a process. Various tuning methods were proposed in literature out of which the Minimum error integral criteria method, IMC (Internal Model Control), 2DOF (Two-Degree-Of-Freedom) method have been suggested for optimum setting of PID controller parameters. In this paper the performance of PID controller is analyzed for various tuning techniques in the case of two tank interacting process control system. The various tunings are performed using MATLAB software. Apart from acquiring the data and processing it, the data can be transmitted to real world with the help of IoT technology. The major industrial problem that has to be rectified is effective transmission of data. The collection and displaying the data on spot is the most commonly used technique. These data are also made to be viewed to the other chief officers and officials off duty through a common portal so that any mishap can be identified and rectified easily. The main industrial parameters in a process tank are measured, processed and is viewed or displayed using Internet of Things (IoT) from any far place using Texas processor interlinked with Wi-fi module.
