A framework of classes for distributed controlling

Today´s controlling systems become more and more complex. One of the base problems for an application design engineer is to build the mostly complex visualization component and the graphical user-interface for the control application. The application program should allow changes in requirement of the system in a very simple way. Conventional visualization systems are not flexible enough to meet this need. The object-oriented class framework presented in this paper supports developers to easily generate control applications by using and extending classes. Distributed data processing by servers and clients is the main concept, which is supported by this application framework
