Introduction
Alpha and IOC magnet software
What will not be supported
What will be supported
Db naming conventions
SLC) LGPS.LX23.1
EPICS) LX23:LGPS:1:<secn>

3. Magnet Functions Alpha Functions Degauss
PS On/off – Must support more than LGPS prims
Diagnostic Knobs (Not Supported)
Module I/O access (Not Supported)

4. Micro Functions Calibrate - MGNT_CALB Diagnostic Calibrate - MGNT_DCAL
Standardize - MGNT_STDZ
Perturb - MGNT_PTRB
Zero - MGNT_ZERO
Check - MGNT_CHCK
Reset - MGNT_RSET (Not Supported)
Touchup - MGNT_TOUC
Trim - - MGNT_TRIM
Dumb DAC output – MGNT_DAOC
IACT to IDES – MGNT__ACT

5. CSTR MAGF
Update the CSTR secondary MAGF for function code from the VAX and don’t have the terse flag set.
MGNT_STDZ
MGNT_CALB
MGNT_DCAL
MGNT_TRIM

8. Database SLC DB units required if using Alpha high level applications
Double duty magnets, special considerations
LTU, Dump and Undulator magnets will NOT be in the SLC DB
Undulator magnets and magnet movers will not be controllable via EPICS or SLC
Phase 1, no control of old SLC magnets from EPICS
EPICS is the master DB when we have both SLC DB units and EPICS PV’s for the same magnet device.
Save/Restore will be done on the EPICS DB and new values pushed to the SLC DB (supertype 2 and 3) at boot.

9. Displays Look and Feel for phases I Status color code maintained
HSTA , STAT and STAT2
SCP Panel Displays
Injector
Linac – sectors 21-30
BSY (use existing panel)
LTU & Dump
EPICS EDM Displays
Will not be able to control SLC magnets on day 1 from and EPICS display
Control and Monitor equivalent displays (Inj,Linac,BSY,LTU,Dump)
Interlock displays – more information avail not passed up to SLC DB

10. Alpha Applications Access Degauss Turn On/Off PS functionality
New verbs
Degauss
Turn On/Off PS functionality
Handle generic CA requests w/ status return from COM files or scripts
Probe
Error Logging
Gold and Configuration files
History and Correlation Plots
Allow analog (e.g. BDES) changes in SLC via channel access
DIMAD and Modeling Applications
LEM
Steering
Chromaticity

11. EPICS Channel Access Clients
Channel Archiver
EDM Displays
XML – still a question but not in phase I
Save/Restore
Channel Watcher
Alarm Handler
Strip Charts
CMLOG
EDM
Matlab

12. Diagnostics
Keep total number of units
Keep total number of units by primary
Keep error counts for unit function failures
Keep number of control functions performed on a unit in the last hour,8hours and 24 hours

13. Loose Ends Unknown extent of modeling application changes
Requirement of 15 minute switch over from LCLS mode to SLC mode and if any SLC db changes need to run LCLS will require ipl of any the Linac Micros.
Streamline DB work especially for those magnets defined in both SLC and EPICS
What to do short of reboot when the SLC and EPICS DB’s get out of sync.
How to control DB edits and EPICS DB edits, and make sure that changes in one DB is reflected in another
Save/restore files. Must save at least the last few versions in case the last version or two has been corrupted as the EPICS db is the master and data will be passed back up to the SCP.
No local control of the PSI magnet ps controllers. Is this a safety issue and can it be addressed?
