THE CONTROL AND THE COMMAND OF THE VIVITRON, A SYSTEM MANAGED WITH ANOODBMS

The architecture of the control system of the Vivitron is distributed. Thirteen VME crates, equipped with MC68040 boards, working at a poten tial from 0 to 20 MV, concentrate the measurements and the commands. T hese concentrators and the control room are federated in a private opt ical Ethernet network. The intelligence of the system is shared betwee n the concentrators. 4 workstations inside the control room are strict ly dedicated to the animation of the graphical user interface, managed with SL-GMS. The mechanisms of communication are only based on indust rial standards. The whole system is described in an object oriented da ta base. Each element, hardware device or software module, is represen ted in the database by numerical values such as addresses, calibration s or thresholds and a specific C function describing its behavior. The data base generates automatically the code exclusively from this desc ription.
