WITHDRAWN: Monitoring and control of various process using distributed control system

Abstract

Distributed Control System (DCS) is dined as a system of controllers connected by a data network which appears like a single system. The functions, the locations, the configuration and the specifications may be different but they all communicate using a single language and hence they are knitted together. DCS is preferred in applications where large number of input output modules are involved in the communication, such as chemical plant or oil refineries. They are multitasking systems able to handle large common databases and allows for various control loops, using graphical representation of function blocks. Monitoring and control of process from a remote station is the need of the hour. DCS is one such provision implemented in most of the process control industries. This proposal is based on controlling the existing process stations in the lab (level and flow process) by using DCS and implementing the concept of Supervisory Control and Data Acquisition (SCADA) in the stations. A user-friendly Front Panel is designed through which the process control panel can be monitored and controlled for the respective stations. Functional blocks are used for programming the Proportional Integral Derivative (PID) Controller for the level and flow process.
