• Old control system Problems:No connection between subsystemsSoftware function was simpleNo database, only parameter backup in some

subsystemsHardware components were out of date and maintenance

becomes more and more difficult

• Phase II project of NSRL started in April 1999 formally.

• Design Philosophy for new control system Adopting distributed architecture Applying standard hardware interfaces:

Sun workstation, Industrial PC, PLC Cost-performance should be considered

Mar. 12, 2008 Li, Chuan: NSRL Control System NSRL 6

• New control system: based on EPICS Operator Interface, OPI LAN Input/Output Controller, IOC

OPI LAN IOC I/O Equipment

• Upgrade process in Phase II Project May 1999: set up a prototype system June 2000: the first subsystem （ storage ring main magnet power

supply control system ） was commissioning. Oct. 2003: the last subsystem （ storage ring octupole magnet

power supply control system ） was commissioning.

• Upgrade process after Phase II Project upgrade EPICS base version to R3.13.10 Continually add or update subsystem:

New transport line magnet power supply control system

New wiggler main power supply control system

Magnet temperature monitor system

Ring Vacuum SIP monitor system

The count of local controllers based on IPC↑(Increase)

→ The reliability of whole control system ↓(Decrease)

• Failure Reason:– CPU fan– Memory bank– The communication protocol between IOC and local

controller is too simple to deal with all kinds of errors because it is designed by ourselves.

• Advantage:– Higher reliability

• SCPI Communication Protocol

• No CPU Board on IPC BUS

– Higher measurement precision• 16 bit AD → 22 bit AD

– No need program for local controllers

A typical operation mode：

• Injection 200MeV electron from linac；• Ramping it to 800MeV；• Tunning lattice ， decrease emittance from

160nmrad to 80nmrad；• Compensation Lattice while charge Wiggler
