  To meet the increasing demand from user community, China decided to build a world-class spallation neutron source, called CSNS(China Spallation Neutron Source). It can provide users a neutron scattering platform with high flux, wide wavelength range and high efficiency. CSNS construction is expected to start in 2011 and will last 6.5 years. The control system of CSNS is divided into accelerator control system and experimental control system. CSNS Experimental Control System is based on EPICS architecture, offering device operating and device debug interface, communication between devices, environment monitor, machine and people protection, interface for accelerator system, control system monitor and database service. The all control system is divided into 4 parts, such as front control layer, Epics global control layer, database and network service. The front control layer is based on YOKOGAWA PLC and other controllers. Epics layer provides all system control and information exchange. Embedded PLC YOKOGAWA RP61 is considered used as communication node between front layer and EPICS layer. Database service provides system configuration and historical data. From the experience of BESIII, MySQL is a option. The system will be developed in Dongguan , Guangdong p province and Beijing, so VPN will be used to help development. Now,there are 9 people working on this system. The system design is completed. We are working on a prototype system now.
