I&C standards: why?
Statements:
1. Most of components or plant systems of ITER are procured “in-kind”
from the seven ITER member partners.
2.These components will come with their own local control systems.
3. For integrated operation purpose, these local control system will be all
interfaced to the Central I&C systems.
4.There will be a huge number of physical and functional interfaces.
5. After commissioning, ITER IO will have to maintain everything.
Main challenge for I&C systems is the integration

How to test and integrate I&C systems ?
Model of Life-Cycle in use at ITER:
1. Manufacture is ended with FAT in supplier premises.
2. Integration on ITER site is ended with SAT and hand-over.
3. Integrated commissioning under IO responsibility.
4. Operation under IO responsibility.
Focus on phases 1 and 2 with following principles:
1. Get an approved design which includes I&C standards requirements.
2. Full compliance to the approved design checked during manufacture.
3. Central I&C interfaces tested at the earliest (FAT) using CODAC solution and
CODAC support: mini-CODAC systems delivered for that purpose.
4. Integration on ITER site is checked and supported by CODAC team for the
connection to the CODAC infrastructure.
Details are still TBD, but draft scenarios addressed in:

Conclusion
 ITER project has Selected I&C standard solutions, architectures and
interfaces for risk reduction and cost saving at procurement
integration.
 The suitability of these solutions has been checked against user
reviews and real use cases implementation.

ITER CODAC is now offering support and training services for
helping the suppliers and users in implementing these solutions.
 Opportunities for the industry shall be investigated mainly with the
procurement suppliers and with IO for procurement integration.
ITER IO is ready for dealing with I&C business for
the detailed design and manufacture phases
