Department of Electronics and Instrumentation Engineering, Kumaraguru College of Technology, Coimbatore, Tamil Nadu, India. ---------------------------------------------------------------------***--------------------------------------------------------------------Abstract - The main objective of this project is to monitor 2. MATERIALS AND METHODS and control all the available process plants in the department laboratory. This project involves fetching the real time process variable data from each process plant and communicating the process data through a common communication protocol via Ethernet medium that will run through the entire field. These real time process plant data will be monitored and controlled in the centralized facility that is available in the remote location. The control decision will be taken based upon the behavior of the process plant and the decision will be communicated back to the respective process plant via the communication protocol available and the process plant considers this as input and varies its behavior accordingly. The centralized and remote monitoring and control facility will facilitate the entire operation for implementing the required control specifications for all the process plants available in the department laboratory with the updated real time control data.
The Siemens PLC (S7-1500) receives the sensor data from the process plants. This data is converted to readable format and is being stored in a cloud database provided by EasyAccess2.0. EasyAccess2.0 provides secure connection with remote HMI and view screens configured for it. The real time data that is being stored in the cloud can be visualized and controlled by providing input to the process station remotely using the same interface. The modified input is instantaneously reflected on the process station and new output is received. This allows for centralized remote monitoring and control.

(Centum VP)
The process plants available in the department are in need for constant monitoring and control remotely, which will also bring up an advantage of eliminating human errors during physical analysis.
These connected process stations with the Weintek IIOT module from PLC have been established via Ethernet cable and the module itself is being powered by a 12v battery. The entire station is linked to the easy Access 2.0 app which helps us monitor the remote HMI by providing secure communication, which can be visualized via CMT viewer

The design aims in building a model that assist in developing the centralized monitoring and control application for the process plant that aims to achieve control over different process variables such as level, flow, temperature and pressure. The final control element is majority of the process plant available in the department laboratory is the control valve. Individual process plant or station available is a single input single output system (SISO). Thus, there exists one process variable and one controlled variable from each process plant. The main objective is to achieve individual control of the process plant along with centralized monitoring and remotecontrol facility.
