  3. We need to establish clear ground rules for the MICE control system so that system designers can make decisions affecting how their equipment interfaces to the control system. • The most important areas are: • Naming convention • Standard software toolkit • Standard hardware interfaces • Application software

  4. Naming Convention It is important to agree a naming convention for all devices connected to the control system as quickly as possible. This will help to provide a systematic, heirarchical view of the equipment from the control system. We should a adopt a convention similar to those used in other recent accelerator projects both for consistency and to allow maximum re-use of software.

  5. Naming Convention The most comprehensive naming convention presently available is that developed for the Diamond Light Source. A modified version will shortly be written specifically for MICE and will be circulated for comments. Typical names might be: TGT-PSU-DRIVE-01 Target drive power supply BLN-VAC-PUMP-04 Beamline vacuum pump ABS-HYD-VALV-02 Absorber hydrogen system gate valve

  6. Software Toolkit • The decision has already been taken to standardise on the EPICS toolkit. • LOTS of information available from: www.aps.anl.gov/epics/ • When specifiying new equipment check the website to see if it is already supported by EPICS. Hundreds of commonly used devices already are. • If your device is not already supported ask for advice from either: • Pete Owens P.H.Owens@dl.ac.uk • Epics mailing list ‘tech-talk’ (subscribe from the EPICS website)

  7. Standard Hardware Interfaces • EPICS supports many different hardware interfaces. To keep systems as compatible as possible the use of Hytec 9010 IOC and IP modules is recommended for most applications. • For more complex situations specialised systems such as VME crates may be necessary. This approach will require considerably more software expertise to develop and integrate.

  8. Standard Hardware Interfaces • The Hytec 9010 IOC supports upto 6 Industry pack (IP) interface modules. • Suggested IP modules are: • IP-ADC-8401 8 channel 16-bit ADC (+/- 10V) • IP-DAC-8402 16 channel 16-bit DAC (+/- 10V) • IP-SI-8515 8 channel RS232 • IP-SIO-8505 16 channel buffered digital I/O

  9. Standard Hardware Interfaces • Daresbury Laboratory are developing support for relay control and opto-isolated monitoring of device interlocks via CANbus. • Many other IP modules are available including: • GPIB interface • Stepper motor control • Scalars • Counter / Timers • BUT – check for EPICS support first and get ADVICE!

  10. Application Software • Most generic control software is already available for EPICS, including: • Display managers – tools to design and display interactive synoptic control diagrams • Archiver – automatically record and archive control requests and significant changes to monitored values • Alarm Handler – Produce an audible and visual indication of any values exceeding pre-defined alarm limits. • These tools will be available to the MICE control system so DON’T RE-INVENT THE WHEEL!

  11. Hands on Tutorial • MC Joined in a EPICS training session with Diamond • We now have two IOC boxes: • LH+PH @ Sheffield – target • MC @ RAL – hydrogen system

  12. Further equipment needs • Beam line power supplies • Interfaces to decay solenoid… • Synopsis controls interfaces… • Monitoring system… • Hardware plus “kit of parts”
