The COSY control system, a distributed realtime operating system: first practical experience at the COSY-injector
M. Stephan, U. Hacker, K. Henn, A. Richert, K. Sobotta, A. Weinert · 2002
The COSY control system is hierarchically organized with distributed intelligence and autonomous processing units for detailed components. Data communication is performed via LAN and over a fieldbus. The host systems are UNIX-based, whereas the field controllers are running a modular real-time operating-system RT/OS. The man-machine interface consists of X-window based workstations. On top of X-window a graphical user interface based on object-oriented methods is used. A distributed real-time database allows access to the accelerator state from every workstation. First practical experience at the COSY injector is presented.>
