Planning for the TPS Control System • Control system frame works => EPICS toolkit. • Commitment to the funding agency and budget consideration: Acquire as many of parts from local vendors as possible • => No VME related manufacture in Taiwan • (~ 35 VME crate system are used at Taiwan Light Source) • Give up VME/VME64x/… solutions for IOC layer. • => Adopt cPCI/PXI, AdvancedTCA, and another embedded solutions for IOC layer. • Borrow available resources from another labs. • Goals of 2008: Control system planning and refine the design. Setup EPICS test bed. Training EPICS staffs.
