Abstract:
SCADA – (Supervisory Control and Data Acquisition) plays an important role in most of the industries like petrochemical, cement and sugar & process industries. And is mainly used to monitor or to control a chemical, physical or transport process, integrated with power system management application functions.
The basic of SCADA lies in automation majorly done by PLCs (programmable logiccontroller). Using this, a project can be done with effective increase of speed, and meaningful processing. Any channel failures can be detected automatically by the use of SCADA with out any human interaction. It will control a complete site. The bulk of the site control is actually done by are remote terminal unit (RTU). Data acquisition begins at the RTU or PLC level. This paper will explain the working of SCADA in control process andapplications. Any SCADA system uses advanced linear electronic components for its working. A state of embedded controller technology will be much suitable to achieve SCADA function in all instrumentation environments.
