Component-oriented architecture for SCADA system

Component-oriented techniques have been increasingly used in software engineering. They have been used to solve distributed computing problems. However, in automation world, these techniques have not been implemented to solve distributed control problems. This paper proposes a component-oriented architecture of supervisory control and data acquisition (SCADA) system for applying into distributed control to inherit strong points of component-oriented techniques. Design pattern and OPC (OLE for process control) technology are also used to increase open characteristics of the architecture.
