1. Introduce of Linac Control System Xiangcheng.Kong Control Group

2. Architecture

3. Main Function n PS control n Vacuum monitor n Modulator monitor n Step/DC Motor control n safe system n

4. Hardware developer

5. Remote IO feature

6. IO Statistics n Vacuum PS Step Motor Total DA4x161x84 148 AD8x16+62x84 302 DI8x16 1x84+7 219 DO1x161x84+218 102 System estimate : ¥350,000 approximate $42,000

7. Special treatment for RS-422 Extra UART reception schematic diagram *Double port out for RS-422

8. Software environment n Windows 98/NT n Visual c++ n Turbo c n NI LabView n ASM51

9. Console n Trace Ball used as PS regulator n MDI Alarm n www Server for diagnosis n Channel Scan

10. Data Exchange Process Control Program TCP/IP UDP/IP 232 Intermediate transceiver for Intranet 232/CAN & 232/422 Bus Driver

11. The feature of 232 transceiver Intermediate n 10 user if TCP Link n Provide UDP Link Access Method n User ID Verify n FIFO Array n Re-transmit while error occur n Home Made

12. (Continue) The feature of 232 transceiver Intermediate

13. (Continue) the 232 transceiver Intermediate for intranet

14. Diagnosis Tool: Channel Access

15. Threshold value Adjustment App.

16. Klystron Output Display

17. Klystron Output Display for Intranet

18. Discuss n Reliable Link is not guarantee in TCP/IP for a long time because of noise. increate main nodes for data exchange. UDP link for monitor system n Local DataBase establish for physics beam tune and them interface. use commerce DB. server/client Architecture

19. Conclusion n Control system is flexible and open. n System diagnosis perfect include. n Only 2~3 person to do all hardware and software. n Graphics class is developing because of less human resource. n EPICS will start basing on the fieldbus lay.
