Today, PLC applications are having a major impact on process engineering. PLC has entered this field with software and hardware for fail-safe, intrinsically safe, and process language-speaking solutions. Controls the entire system. The installation cost is not low, but it is possible to operate efficiently for a long period of time. Reduce operating costs and energy consumption. Chiller Units have become an essential requirement in industrial and domestic environments. On the other hand, industrial automation tools provide many applications to control and monitor equipment, power etc. By initiating an automation process, it improves the benefits of managing and controlling chiller plants. PLC and SCADA are easiest automation tool in HVAC industries. The Simatic S7-400H controller is used to automate the process with the rated supply of 24V DC, achieved by implementation of SMPS for the input voltage of 230V.
