SOFTWARE ARCHITECTURE OF THE U-70 ACCELERATOR COMPLEX NEW CONTROL SYSTEM
V.P. Voevodin · CERN Document Server (European Organization for Nuclear Research) · 1999
The software of the new control system of the 70GeV accelerator complex is built around the distributed real time DBMS SSUDA with emphasis on control of technological process, not equipment. SSUDA was designed to store current states of dynamic parameters and supports 3-D tables. The tables are distributed around all levels of the CS, including equipment controllers. So, DB access protocols are used to access ECs. There are only two data-oriented atomic objects that applications deal with: vector and structure. All tasks interact exclusively through DBs and each task belongs to one of three weakly related types: data processing, hardware I/O and manmachine interface. The organization of parameter value storage is standardized, so data processing and I/O applications are highly unified. Only the console program serves the MMI for all tasks that are solved by operators and accelerator physicists.
