3. Our Strategy Choose appropriate technology
For high level controls, use software developed for TI8,TI2, LEIR
For new systems apply industrial solutions when appropriate
Cryogenics, Quench Protection, Powering Interlocks
Integrate together high level with industrial controls
Develop once, using a simple, iterative development model
Use standard components where possible
Common CO general services (Alarms, Logging, FDs, PM, …)
Validate complete integration of our systems
Build on every possible controls milestone
Dry runs
Improve the functionality
Go from simple to more general
Solutions deployed progressively to meet successive milestones

15. Post Mortem - Data Collection
The Process
Source systems push PM data to PM server
PM server saves data in a standard format
PM analysis tools access those files
Where we are now
Data collection chain is tested with PC system PM data
Prototype PM browser in place
Issues with CMW server seen during PC tests are being investigated

16. Post Mortem - Analysis QPS PIC PC Four level analysis Where are we now
Event analysis
Interaction analysis (QPS-PIC, PIC-PC)
Per system analysis (QPS, PIC, PC)
Data Verification
Where are we now
UR are under discussion (SACEC)
Start with the QPS as a pilot analysis
PM analysis needed in Dec ‘05 for the Interlock & Powering tests

17. Fixed Displays Implementation based on TI8 Fixed Displays (FD)
Graphical representation of data in place
Add functionality for text representation

Conclusions

19. Issues - Data Exchange Communication packages
Between different systems
QPS to PIC (QPS gives the power permit)
Tunnel Cryogenics system with Vacuum
Sequencer with QPS, PIC, PC
Fixed Displays data collection (Cryo, Vacuum, PC, CV,…)
Communication packages
CMW, AB/CO standard for all CO communications
CMW -> PVSS interface available in Aug ‘05 [FD, Sequencer]
PVSS -> CMW interface available, prototype in place [QPS, PIC]
DIP, CERN-wide for inter-domain data publication
DIP <-> PVSS interface available (IT/CO) but not yet operational [Vacuum, QRL]

20. Issues - New Software Development
Many new applications under development
Tunnel Cryogenics controls
QPS
PIC
Post Mortem
Fixed Displays
Data exchange communication interfaces
Software will be ready in time for HWC, but a challenge for validation
Use simulation for tests and debugging
Connect to real system when available

21. Issues - User Requirements
Tight links with SACEC for the cold circuits
All other systems yet to be studied !!
Know what is needed for
Short circuit tests
24-hour heat run
Interlock tests
Working on
Powering tests
Post Mortem requirements

22. Issues - Resources Same people - competing activities
LEIR - HW and beam commissioning [Apr-end ‘05]
CNGS [end ‘05]
LHC Inj. Lines commissioning (TI2) [Jun 05]
CCC [2nd 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

23. Issues - Computer Security
New security policy on TN from Jan ‘06 -> Isolate from hackers
No major implications on HWC and FCR if on TN
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

24. Conclusions
The hardware commissioning is a major milestone and a new phase for controls
Controls critical for HWC, LSS8L important for Controls
It is the first time that high level and industrial based controls will be integrated
Integration with CMW is a critical issue
A lot of software is now in place and validated
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
Controls availability and automation are essential to meet schedule and save time
Implement basic functionality and improve progressively
