Our Strategy o Choose appropriate technology n n For high level controls, use software developed for TI 8, TI 2, LEIR For new systems apply industrial solutions when appropriate o n Use standard components where possible Common CO general services (Alarms, Logging, FDs, PM, …) Validate complete integration of our systems n n o Integrate together high level with industrial controls Develop once, using a simple, iterative development model n o Cryogenics, Quench Protection, Powering Interlocks Build on every possible controls milestone Dry runs Improve the functionality n n Go from simple to more general Solutions deployed progressively to meet successive milestones Eugenia Hatziangeli AB/CO 3 HC Review 2005

Issues - User Requirements o Tight links with SACEC for the cold circuits n o Know what is needed for n n n o All other systems yet to be studied !! Short circuit tests 24 -hour heat run Interlock tests Working on n n Powering tests Post Mortem requirements Eugenia Hatziangeli AB/CO 21 HC Review 2005

Issues - Resources o Same people - competing activities n n n o o LEIR - HW and beam commissioning [Apr-end ‘ 05] CNGS [end ‘ 05] LHC Inj. Lines commissioning (TI 2) [Jun 05] CCC [2 nd half ‘ 05] SPS & CPS start up with major changes [end ‘ 05] Due to tight resources, we aim at basic functionality and improve progressively Improvements need qualified software engineers; it takes several months for newcomers to understand accelerator needs Eugenia Hatziangeli AB/CO 22 HC Review 2005

Issues - Computer Security o New security policy on TN from Jan ‘ 06 -> Isolate from hackers o No major implications on HWC and FCR if on TN n n For clients on GN no direct access to equipment on TN Dedicated Gateways will provide connectivity Formal authorisation for new equipment on TN No Wireless & DHCP on TN Eugenia Hatziangeli AB/CO 23 HC Review 2005

Conclusions o The hardware commissioning is a major milestone and a new phase for controls n o It is the first time that high level and industrial based controls will be integrated n o Integration with CMW is a critical issue A lot of software is now in place and validated n o Controls critical for HWC, LSS 8 L important for Controls Use existing software where possible but new software is required and very high pressure on specific resources Dry runs for all critical systems Requirements studies for systems not covered by SACEC should start in good time HWC has a tight schedule but so has AB/CO n n Controls availability and automation are essential to meet schedule and save time Implement basic functionality and improve progressively Eugenia Hatziangeli AB/CO 24 HC Review 2005
