THE EVOLUTION OF THE DAFNE CONTROL SYSTEM: A HISTORY OF LIBERATION FROM HARDWARE
G. Di Pirro, G. Mazzitelli. I. Sfiligoi, A. Stecchi · Prepared for · 2001
During the DAFNE [1] commissioning and run operations the Control System [2] has been continuously evolving in order to fulfill the user requirements and the needs of a complete accelerator management. The original structure of distributed CPUs relaying to a central shared memory proved to be scalable and suitable for adding functionality ’on the fly’. After 5 years of operation, the system had reached some intrinsic limits so that we focused on an upgrade plan mainly regarding the user level and the capability of the system to connect to external resources. The re-engineering was done thinking to the maximum software reuse and the original choice of a commercial software environment for all the control applications demonstrated to be valid allowing to redesign the user level with no worries for the porting.
