Introduction
SDUV-FEL is pre-search of chinese hard X-ray FELThere are several FEL facilities is under construction
LCLS (Linac Coherent Light Source)EURO-XFELSCSS(SPring-8 Compact SASE Source)
SDUV-FEL control system is an extended system based on 100Mev linac control system
Keep no change to those old devices which existed in 100MevNew devices will be added in through extended cards/busesAlmost all of new devices can use the control method in SSRF
Total system can be separated to following sub systemsInjector sub-systemLinac sub-systemUndulator sub-systemTiming and interlock sub-system

System DesignSDUV-FEL control system is a distributed system based on “Standard Model”OPI LayerFront-end LayerDevice control Layer
Ps controllerVacuum controllerPump ps controllerPLC, etc.
Network/filedbusesLAN, DeviceNet, serial, etc.
As we upgrade from the old control system, we obey the rules “use old devices as much as possible”

Device Control - Valve Control
Use AB PLC-5 to control valves and implement interlockThere are 3 vacuum parts
Injector (valve V1,V2) Linac (valve V2,V3)Udulator (V4,V5)
When the guage value reaches alarm, relay breaks, PLC output to close valves at both endsComparing with old 100Mev control, 2 modules of 16 channels are added and new control logic was designedPLC communicate with VME/IOC based on AB’s DCM protocol
