SNS Integrated Control System
Oracle – IOC Application Setup
(From MPS but could be any application)

Setup Utility adds or modifies applications to an IOC

(Data can be initially populated by crawling cdCommands)

Adds directory paths to required file(s)

Each IOC application (i.e. VxStats) has a similar setup window.
1.
HW init calls
2.
SW Init routines
3.
Post IOC init

Oracle – Hardware setup

Application setup adds hardware, db applications, sequencers, etc.

For example VME board / PCI card info

»

Hardware address
Interrupt vector
Hardware version
Serial number
etc.
Custom setup for each
type of hardware
MPS – Hardware jumpers
PMC cards
Use Heartbeat?
SNS Integrated Control System
Oracle – Channel Setup

Creates “.substitutions” file. Each channel gets instantiated with the
template file(s) previously shown.

ADEL, MDEL, SMOO come from manufactures hardware specs and
physics requirements

MPS shown below (Software mask jumpers, Mode Masks, etc.)
» Configuration Control and reporting)
Data comes from a
number of Oracle
Tables
Need an easy way to get
data from RDB table(s)
to .substitutions file

Power Supply Application

Initial data came out of
excel spreadsheets
» Power Supply limits (V
and I)
» IOC assignments
» Channel assignments

Archiver configuration
files
Initially many sets of
files, outdated, wrong.
Led to operational
errors
SNS Integrated Control System
PS / Magnet data from RDB

Power Supply Calibration (from
EPICS)

PSC / PSI calibration history

Power supply limits from
manufacturer (RDB)

Operational Limits (Ops, magnets,
cables, heat waves, etc)

Magnet mapping files

Magnet cycling profiles

SCORE – PS save / restore

Magnetic field set points from
accelerator physics model (or
golden tune, or last weeks tune,
etc)
» Alarm limits
» MPS trip levels
SNS Integrated Control System
Status
Data is getting into Oracle (Bar code
constraints)
.Substitution files are getting generated
Problems – Future Plans

Problems using an RDB
» Controls Group Acceptance (We didn’t do it this way)
» Need EPICS or Engineering user interface
» ACCL-SRV1 needs to be mirrored for Oracle development
» A lot of overhead to set up, lack of RDB experience
» Too many constraints, held up because of missing bar codes

Status and Future Plans
» Archiver Configuration, Report generation
» ~45 MPS IOC’s and 60 MPS chassis configured
» Power Supply IOC Application (testing)
» Argonne Collaboration (IRMIS)
» PV application locator (IRMIS)
» Oracle mirror on ics-accl-srvxx (In progress)
» Use RDB for Global System configuration (100’s of IOC’s to
manage, will not be able to upgrade all at once)

Signal Management – Import .DB/Templates
Startup.cmd imported
(crawler App keeps
Oracle up to date)
Bad signals,
duplicates signals, etc
flagged.
New verses Old
comparison
Files generated by
Oracle go back into
the RDB, verifies what
is loaded by IOCS.
