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

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.

ITER I&C System

Interfaces with domestic agencies and suppliers

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

ITER I&C System Architecture

ITER I&C System Architecture

ITER I&C System Architecture 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

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

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

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

Location of plant I&C systems

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!

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

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
