The control system of ROSY I

ROSY I is a planned synchrotron radiation light source with a number of straight sections for wigglers and undulators for photon energies in the range from 1 keV to 20 keV. This paper describes the design principles of the fully distributed architecture of the ROSY control system, pointing out the extensive use of de-facto standards for both hardware and software such as UNIX, X11/Motif, VMEbus etc. Particular attention is given to the implementation of the man-machine-interface, the design of the distributed online database, the homogeneous communication architecture and the integration of data processing and feedback in the realtime environment of the process layer.<
