Applications provided by the Legacy system
The slc-aware IOC allows the legacy system to control and readback all new magnets,
and provides beam synchronous data to High Level Applications in the Legacy system
from:
BPMs, Faraday Cups, Toroids
Still to complete: LLRF phase and amplitude
Highest priority: A new Save/Restore app is needed to handle both existing and new
devices

Save/Restore Requirements - Groups
System and User Groups
System - organized by SLC regions
Injector, 21-BSY, LTU-Dump
User - on the fly
Groups of groups
Configure wildcarded lists of signals & associated readbacks, thresholds, status…
Compare against master RDB
Resolved via user command; upon Save (Create Snapshot)
Group relationships - track overlapping signals
Subsystem/device behaviors
Multi-step restore
Post-restore processing
Conditional save/restore
API
BPM Reference orbits, Multi-device knob,…

Save/Restore Requirements - Snapshots
Repositories - Normal, Scratch, Temporary with different retentions
Tags - Current, Gold, last loaded, …
Retrieval via search mechanism – by group, repository, date, title, author, tag, comments
Comparison of multiple snapshots in the same group
Display snapshot by subsystem, area; report disconnected signals
Comparison of live values to stored; readback comparison to assess restore success
Programmable signal threshold for compare color coding
Edit data values prior to restore, then “save as”
Restore
Partial
Multi-step (Activate, Trim)
Conditional, Post-processing
Report restore status; Roll-back option
API

Save/Restore Phase 1 – SCORE Modifications
XAL SCORE satisfies many requirements
Will service all magnets, LLRF, new timing, all new epics subsystems
Data Provider - add AIDA
Determine SLC/EPICS data source per signal
Implement polling of AIDA devices to get data
Modify AIDA SLC Magnet Data Provider
Processing - add Multi-step restore for magnet subsystem
RDB – add APEX support
Highly capable APEX app -upload spreadsheets to populate groups; duplicate/ integrity signal
checking
GUI
Rearrange/add columns; modify comparisons
Add error/cmlog logging
