IRMIS at CLS

Where is Saskatoon?

Saskatchewan Accelerator Laboratory

• Originally established in 1964 as the Saskatchewan Accelerator Laboratory (SAL)

Canadian Light Source

• In 1999 the SAL accelerator was re-purposed as an injector for the CLS

• Between 1999-2003 a new booster and storage ring was constructed.

CLS USES IRMIS ASA CONTROL SYSTEM

SEARCH TOOLI

IRMIS Search Tool(Current use at CLS)

• IRMIS supports our ability to search for IOCs based on PV names

• To accomplish this we use a modified pvCrawler from the original IRMIS release

• A simple web-interface written in PHP

PV search system architecture

pvCrawler - Linux based IOC(Current use at CLS)

• Moxa (used for serial or USB devices)• Intel (using optical Links to VME crates)• Applications located on a central file

server, NFS mounted as /IOCApps

• IRMIS crawls the NFS mount for db information

pvCrawler RTEMS based IOC(Current use at CLS)

• Primarily diskless machines• Programming comes off the central file

servers using bootp

• IRMIS crawls the bootp directory for db information

pvCrawler(future enhancement)

• Ability to identify source files that make use of a PV:– EDM Files– CSS Alarm Handler– EPICS State Notation Language– EPICS Gateways– EPICS Data Archiver– Matlab Code (accelerator toolbox)– Python Code (used on the beamlines)– AutoCAD Drawings

Potential benefit

• Motivation for additional crawlers:– Tool used to identify the impact of changes

(critical for maintenance activities)– Database can then be scanned for

consistently:• Identify dead-pv’s that are not used anymore• Use of incorrect data types/attributes• Other consistency/correctness checks?

GENERATING DB FILES

I

For Modicon PLCs(currently not part of IRMIS)

• Modcion Momentum PLC variables follow a standard naming convention

• An awk script parses the PLC variable list, and uses template substitution files to generate epics definitions

• We currently don’t generate configuration files for the data archiver or EDM screens, however it is done by other labs, e.g., TRIUMF

Current Process for Generating PV from PLCs

Standard *.tpl files

IOC build

*.db files

• Process driven by Make files• Current limitations:

– Alarm limits, variable descriptions are hardcoded into the tpl (templates)

– Attributes of PV are hidden and notvisible to users

• Could IRMIS do a better job?

CABLES DATABASE

I

Cables Database

• History of Cables Database– Original implementation on PDP-11– Converted to SunOS/PostgreSQL– 1999 Converted to MS-SQL Server– Now being converted to Java

• Critical features is each cable being numbered

Cable search system architecture

Requirements Capture

• We currently capture control systems requirements on PID drawings and word documents

• Longer-term we want to move towards computerised requirements management that makes use of integrated change control and configuration management

MKS

• We use MKS as our configuration management tool and for change requests

• We also group change requests into “work packages” (aka a project) with a project charter.

• Our next step is to start to capture requirements and provide the traceability from requirements, down to the implementation

ELECTRONIC LOGBOOK

I

Electronic Logbook

• We use the TRIUMF electronic logbook system.

• Simple web interface and fairly simple implementation

• Mostly implemented in Perl running on top of PostgreSQL.
