DISTRIBUTED INTELLIGENCE IN A LAN ARCHITECTURE INCREASES THE FLEXIBILITY IN CONTROL SYSTEMS FOR FUSION EXPERIMENTS

The control system for the TEXTOR Neutral Beam Injectors is designed implementing approved concepts and techniques. A powerful super mini computer serves as a central node between the operators console and the experimental process. State of the art devices form a console for suitable man machine interaction. The link to the process is mainly based on communication with a network of industry standard programmable controllers. A distinction is made between the functionally dedicated and in most cases locally distributed logic controllers, a central controller and the computerized console level. Introduction of such networks in control systems for fusion experiments results in a number of advantages.
