1. PLC Based Interlock systems Workshop 4-5 December 2014 - ITER Organization Headquarters - St Paul-lez-Durance-France ITER Central Interlock System: Central Interlock Networks Y. LIUDec. 2014

2. PLC Based Interlock systems Workshop 4-5 December 2014 - ITER Organization Headquarters - St Paul-lez-Durance-France Table of Topics  The demand for ITER CIN  The CIN Characteristics  The CIN Architecture  The CIN Infrastructure

3. PLC Based Interlock systems Workshop 4-5 December 2014 - ITER Organization Headquarters - St Paul-lez-Durance-France 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.

4. PLC Based Interlock systems Workshop 4-5 December 2014 - ITER Organization Headquarters - St Paul-lez-Durance-France 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

5. PLC Based Interlock systems Workshop 4-5 December 2014 - ITER Organization Headquarters - St Paul-lez-Durance-France  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. CIN Characters

CIN Infrastructure – Principals MCR Synchronization BCR CNP -CNP is a passive wall mounted patch panel which is the physical termination point Interlock Networks. -Network panels are installed at strategic locations close to the PIS cubicles CIN Cubicle: Network cubicles have interlock network switches installed side and located in rooms called CODAC hutch. MSRBSR CNP CIN Cubicle In CODAC Hutch PIS slow PIS Fast

9. PLC Based Interlock systems Workshop 4-5 December 2014 - ITER Organization Headquarters - St Paul-lez-Durance-France Conclusions CIN uses following measures to enhance the Network availability and performance:  Network redundancy Cable Segregation Data Segregation by VLAN technology. Network Segregation: CIN-A, CIN-P  All kinds of Segregation measures:  Gigabit technology
