In this paper, we first review existing approaches of XML Web Services for process monitoring and control, and then provide the limitation under consideration of existing approaches. We propose a framework for implementation of OPC Web Service based on SOA (Service-Oriented Architecture), OPC UA (Unified Architecture) technology, and OOD (Object-Oriented Design). In order to overcome the limitation of the performance of XML Web Services, the binary data representation is to use in the proposed framework. Our framework obviously makes it easy to deploy,maintain and is effective for applying to the control and monitoring systems. In addition, the performance analysis and discussion demonstrate that our system has a good performance and is feasible in order to apply to the distributed data acquisition and monitoring systems.
