Responsibility Limits - Inside 1/2The Controls group

provides core control functionality & applications (HWC sequencer, equip state, equip monitoring, SDDS,…) in collaboration with AB/OP

produces and maintains standard facilities (Logging, FDs, LASER, JAPC, SIS, BIC, OASIS, CCM, …)

develops, maintains and supports UNICOS based applications (Cryo, QPS, PIC, WIC,..) for industrial control system

provides support for modeling of the Controls database (SPS, HWC, LEIR, LHC) and for the logging and measurement services (Timber, Meter)



Responsibility Limits - Inside 2/2 AB/CO is also providing development environment, tools and graphical components to be used by application developers, equipment and MD specialists

FESA editor Java dataviewer General purpose graphical beans Java GUI frame LabVIEW development environment UNICOS frame Working sets & Knobs Jython Build and release tools Software support to developers

µCR



Responsibility Limits - Outside

AB/CO is NOT responsible for

equipment expert GUI applications (except QPS, CRYO)

Frameworks for LHC ApplicationsThree approaches in place to build applications

Beam based control applications Majority of applications Java infrastructure

Industrial control PLC/SCADA based applications UNICOS frame based on PVSS

Post Mortem data analysis Based on LabVIEW



Our Approach to Java Applications Development

A considerable amount of applications for stage I & II is requested

This will be achieved since we have put in place a common architecture based on a solid core functionality a standard equipment access reusable software components standard facilities

upon which the LHC applications are being built

This requires high competence in software engineering for core development BUT it pays back Complex self contained applications are replaced by

light weight GUI applications which are easier to develop

GUI applications based on the core are less error prone

LHC Java Applications - Organization The work is done in a close collaboration with the OP group - we work in a team

One single project in place (LSA *) providing the common architecture

Aim to use for several accelerators TT40, TI8, HWC, LEIR, SPS, sector test and LHC

Test using every possible controls or operational milestone and several dry runs

* In 2006: 4 CO FTE and ~5 OP FTE

• Critical instrument (BLM, BPM, BCT, BTV) applications applications are assigned

• BLM and BPM concentrators are taken care by LSA core

• Within the following 3 months the application responsible with the equipment specialists will define the operational APIs of critical instrument and a test plan (when we need what)

This should result in simulation equipment servers in place by the eq. specialists

• Resources for tune and luminosity will be found in the 2nd half of 2006

Issues - Resources The system architect & core developer leaves CERN

in May

Major core activities are staffed by temp or departing staff

The same application developers are working for HWC, LEIR, CNGS, PS and SPS startup and ….. what is left of them … for LHC Beam Operations…

LHC applications list not fully staffed clearly showing lack of resources

We need experienced Java software developers



Issues -Time allocated for Testing

While TT40/TI8, HWC, LEIR, and SPS ring will be used to test the LSA core and applications extensively, …

the tests foreseen in 2006 CNGS TI8/TT40 sector testwill be the only validation of the LHC software, so …

we need well coordinated dry runs beforehand

We request time allocated during LHC commissioning for the final tests of the deployed software



Issues - Remote Access and Security

Experts and piquet require access to LHC controls from outside the CCC

Who has the right to modify LHC parameters? Control of certain devices (Schottky) from other institutes is already requested (US-LARP collaboration)

We need remote access and role based access policy and manpower to implement it CNIC is not the answer



Conclusions Solid architecture on which to base the LHC

applications exists with main core services and several GUI applications already deployed

Tested and validated with TT40/TI8, HWC, LEIR, SPS, CNGS and sector test

We have a complete list of the LHC applications/developers

http://cern.ch/ab-lsa/planning/commissioning.htm

but with some holes …

There are issues on resources, time for testing, remote access and security

We have the right tools for the job and we will be able to do it, provided effort is not diverted into lower priority work
