XML-based monitoring and operating for Web Services in automation

Web services in automation systems usually use XML technology for data exchange functions. Actual Web browsers include XML functionality already as standard and therefore they are very promising candidates for implementing monitoring and operating functions of Web services. But Web browsers typically incorporate only a subset of Web technologies and their availability may be characterized by a relatively short live time compared to automation solutions. So many existing libraries for Web based monitoring and operating are implemented with Java and some new versions of browsers do no longer support Java natively. An interesting alternative are XML-based graphical user interface languages developed for the office world, but existing languages do not meet the requirements of real time visualization in automation. To overcome these deficiencies this paper presents a new language for Web based monitoring and operating supporting Web services for the data exchange.
