PLC BASED PID IMPLEMENTATION IN PROCESS CONTROL OF TEMPERATURE FLOW AND LEVEL

In the present Industrial scenario the Temperature, Flow, Level, Pressure and density of a process is controlled using the Proportional-Integral-Derivative (PID) controller which is based onmicrocontroller. Out of the above mentioned variables controlling, Temperature control is very difficult by using ordinary control techniques; hence the motive of our research is to implement PID controller design along with programmable logic controller (PLC) in order to control the time to heat up aparticular solution to a desired temperature efficiently without sacrificing the stability of the system. In this work the controlling is based on PLCMISTUBISHI NEXGENIE 1000 NG14RL along with some Analog cards. In this work the controlling of PID controller isperformed by using ladder diagram in PLC software Codesys ENE server V2.3.
