Abstract
This paper combines OPC (OLE for Process Control) standard to EWS (Embedded Web Server) in order to distribute an integrated service for accessing real-time and history data from control networks. A layer of OPC XML-DA (Data Access) service is added between web services interfaces and embedded operation system in OPC-EWS. Architecture of DCS (Distributed Control System) with OPC-EWS is described too. This OPC-EWS applies such technologies as OPC, Java and XML and links to Internet through TCP/IP. Therefore, accesses to all kinds of embedded devices and data share in the heterogeneous Internet/Intranet environment are implemented. At last real-time performance and security of OPC-EWS are analyzed. The experiments and application have demonstrated that the architecture has good performance and is feasible for real-time operation in DCS.
