Block Diagram

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 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. June 3, 2005 SLC-Aware IOC Review K. Luchini luchini@slac. stanford. edu

Displays Look and Feel for phases I Status color code maintained HSTA , STAT and STAT 2 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 June 3, 2005 SLC-Aware IOC Review K.

Diagnostics 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, 8 hours and 24 hours June 3, 2005 SLC-Aware IOC Review K. Luchini luchini@slac. stanford. edu

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? June 3, 2005 SLC-Aware IOC Review K. Luchini luchini@slac. stanford. edu
