The Demands for ITER CIN
The situations:
Large area to cover, large scale to connect in:
About 40 PIS from 23 PBS involve in ITER interlock
system,
The PIS located in 13 different buildings.
Redundant CIS requires redundant networks to
enhance the network availability.
Large amount data requires high performance
networks.

CIN Characters
A total redundant ITER Interlock Network covers ITER
buildings to connect Plant interlock systems.
Conventional TCP/IP networks is base on Gigabit
Ethernet technology: Gigabit switch, fiber optic cables
start and end at central/local interlock cubicles.
Network segment: two isolated sub-networks
• CIN-A: Connect operator station, engineer station and CIS
modules (PLC, Fast controller, servers…) for administrative
tasks (monitoring, archiving, engineering configuration…)
• CIN-P: Connect CIS modules (PLC, fast controller, supervisor
module) and Plant Interlock System for process control,
operations, timing propagation, diagnostics

CIN Characters
VLAN technology used to segregate data to increase
the CIN-P performance:
– VLAN for interlock slow architectures (PLCs)
– VLAN for fast controllers
– VLAN for hardwired architecture diagnostics data
Separated paths for backbone fiber cables.

Conclusions
CIN uses following measures to enhance the Network
availability and performance:
 Network redundancy
 Gigabit technology
 All kinds of Segregation measures:
• Network Segregation: CIN-A, CIN-P
• Cable Segregation
• Data Segregation by VLAN technology.
