Abstract :
The architecture of the control system of the Vivitron is distributed. Thirteen VME crates, equipped with MC68040 boards, working at a potential from 0 to 20 MV, concentrate the measurements and the commands. These concentrators and the control room are federated in a private optical Ethernet network. The intelligence of the system is shared between the concentrators. 4 workstations inside the control room are strictly dedicated to the animation of the graphical user interface, managed with SL-GMS. The mechanisms of communication are only based on industrial standards. The whole system is described in an object oriented database. Each element, hardware device or software module, is represented in the database by numerical values such as addresses, calibrations or thresholds and a specific C function describing its behavior. The database generates automatically the code exclusively from this description
