The SSRF power supply control system
Liren Shen · Nuclear Techniques · 2012
The SSRF power supply control system is a fully distributed control system based on the EPICS system.About 65K runtime database records run in the 27 VME/IOC controllers to make physics access more than 600 sets of power supplies distributed in the SSRF facility.In this paper,the layered system architecture and its working principles are introduced.The EPICS-based control solutions for the PSI-designed and SINAP-designed digital controllers are described.The hardware and software,together with the communication technology applied in the system,are presented.
