3. The ITER I&C system – making ITER work
Everything you can see has I&C that is part of the overall integrated ITER I&C system.
My talk is about integration, looking at the macro, not the micro

4. A bit of interface problems
ITER I&C System
The Control System is the system which functionally integrates the machine
ITER Agreement splits the project in procurement arrangements distributed among the seven members
Missing items
Island mentality
A bit of interface problems
Ahhh,I forgot that I need that in my system
That should be implemented in your system, not mine
Ahhh, we forgot there is an interface between A and B
We changed the design so the interface does not exist anymore
Ahhh, I did not know the others are doing the same thing in a different way
I do not care what the others do. I build my system.

7. ITER I&C System Mission Statement
Ensure all ITER plant I&C systems are designed, implemented and integrated such that ITER can be operated as a fully integrated and automated system.
Successful integration = higher reliability
Minimize required operators
Minimize required maintenance crew
Minimize operator human errors
Operate from a single control room
Use only standard equipment in control room

CBS
Level 1
CBS
Level 2
ITER control system is broken down in 18 ITER control groups (CBS level 1)
An ITER control group contains many Plant System I&C (CBS level 2)
A Plant System I&C is a deliverable from a procurement arrangement (IN-KIND)
A procurement arrangement delivers a part, one or many Plant System I&C

12. Design maturity of I&C systems
All central I&C systems are in final design phase
Final design reviews planned for 2016 and 2017
Most plant I&C systems are less mature
Risks:
I&C needs from other systems are not known until too late,
E.g. cabling, networks, power, environmental, structural

13. Central Networks Infrastructure
Build-to-print design available
Call for Nominations of supply and installation to be launched now
Start of installation scheduled 2016
Bill of Material
177 cubicles
186 passive network panels
300 km multi-core single mode
100 km multi-pair copper cables
Connecting thousands of plant system I&C client cubicles located in ~90 buildings and plant areas via network panels located in 25 buildings

14. Plant system I&C focus Building services Utilities
Poloidal field coil fabrication building already monitored by CODAC
First operational building for site electrical supplies will be ready 2016
Utilities
Construction electrical supplies already monitored by CODAC
Steady state electrical supplies start to operate in 2016
Reactive power compensation system ready in 2017
Cooling water system
Non-tokamak cooling will be installed from late 2016
Coil power supplies
ACDC converters will be installed and commissioned in 2018

15. Location of plant I&C systems

16. Risks with non-standard technologies
Communication incompatibility
Lack of diagnostic coverage and fault-tolerance
Absence of health and performance monitoring
Unable to implement local/remote HMI switching
Examples of known non-standard technologies:
LabVIEW-RT based controllers
QNX-based controllers with custom made drivers
Custom made PCBs without long-term manufacturer support
Safety relays and logic without diagnostic capabilities
Every non-standard technology adds additional unnecessary difficulties
The challenge is great enough already!

17. The main challenge for ITER I&C System is
INTEGRATION
MITIGATION
Defined standards, specifications and interfaces applicable to all plant systems instrumentation and control (PCDH)
Develop and distribute a control system framework that implements standards defined in PCDH and guarantees the local control system can be integrated in the central system (CODAC Core System)
Provide I&C Integration Kit free of charge (PSH, Mini-CODAC, switch)
Provide catalogues of tested hardware (PLCs, industrial computers, safety logic controllers, I/O and network cards, network switches, cubicles and monitoring systems)
Framework contracts and dedicated contacts for key hardware suppliers
Provide User Support
Organize Training (PCDH campaign, CODAC Core System hands-on training at IO and DA, videos on Online Learning Centre)
Implement Pilot Projects to prove the solutions
Organize User Meeting

18. Conclusions
The ITER I&C system is big, but it is also organisationally complicated
Integration of the ITER I&C system is essential to meet the project objectives
The project has taken many measures to mitigate risks
Non-standard technologies are a significant threat to successful integration
Central I&C systems are in final design
Central network infrastructure installation is planned for next year
Integration of plant I&C systems to central I&C systems has already started and will soon become our main activity
