Abstract
Nowadays, in process industries, commonly used process Controllers/Systems are Supervisory control and data acquisition (SCADA), Programmable logic controllersand distributed control systems. Used of any of the Controller/System particularly dependent upon the type of Input/Output, response time, cost, complexity of the process, process-oriented/data-gathering-oriented, Process state-driven/event-driven, etc. Process control refers to control the sequence of activities in a process plant according to the requirement of the final product in the most economical way. Using an Automatic control system, we can monitor and control the process in real-time, identify and rectify the problem, and adjust (program) according to the requirement. This paper gives insight into system hardware for Controller and Input/Outputs and hardware for Distributed Control System (SIEMENS-PCS7) workstation. This paper describes the logic and algorithms applied to control a plant with the help of languages such as Sequential Function Charts (SFC) and Continuous Function Charts (CFC). It discusses the display designed to control a plant by the operator in detail. Also, it includes the proportional–integral–derivative (PID) optimized control loops for temperature and level control.
Keywords
Process Control, Distributed Control System (DCS), Multiple Input Multiple Outputs, Continuous Flow Charts, Proportional Integral Derivative Controller.
