The Internet brings many new features to the process control and automation field, which were previously difficult or costly to implement in traditional control systems, such as remote accessibility to the plant, information sharing, and software standardization. The Internet, however, has its limitations when compared to a traditional control system in terms of functionality, performance, security and reliability. Recent emerging web technologies are promising to overcome many of these limitations, and are helping the Internet to evolve into a highly graphical, interactive and collaborative environment. In this thesis, we investigate the design and applications of Internet-based Supervisory Control & Data Acquisition (SCADA) systems. SCADA systems are typically distributed in nature and are more suitable for this investigation than other types of control systems. First, we provide an overview of what is currently being done to implement Internet-based SCADA systems and compare them to the traditional SCADA systems. Then we discuss the latest web technologies and analyze their uses in industrial automation. Finally, we evaluate how certain web technologies, namely Java and XML, can improve Internet-based SCADA systems. This is done by proposing a software design for a web-integrated SCADA system using the standard UML design approach.
