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.

Software EnvironmentControl system framework: EPICS toolkitHigh level physics applications:

=> Depend upon machine physicists’ preference => Matlab/Accelerator Toolkit/Matlab Middle Layer

another framework (e.g. XAL frameworks) is also in study=> Setup virtual accelerator to support high level application development is in planning.

Many items are still in study => Relation database => Technical system interface => Documentation, E-log => Machine status broadcasting: web, IPTV, … etc.

What are our major focus now:1. We are no real experiences on EPICS => Do our best to increase

slope of the EPICS toolkit learning curve.2. Work out on device/driver support for various selected hardware..

The design of the TPS control system is on going. All major components for control system are in intensive study. Standardization hardware and software are the current focus. EPICS toolkit training - a series training activities will be arranged. Set up EPICS test-bed Single kind of operating system solution for IOCs and consoles are preferred

=> Linux. Economy design without scarify performances and reliability are the goals. Select possible outsourcing items Learn experiences from another labs Help from the EPICS community is absolutely essential!
