2. SEMINARIO CERN a LNL/INFN
CERN/UNICOS un oppurtunita per il rifacimento del sistema di controllo criogenico al LNL?
Dr Marco Pezzetti 2

3. CERN distributed control system

5. 1) Retrieve and structure information
UNICOS PLC components
5) PLC programming
2) DOC: Operational Logic
3) DOC: UNICOS Spec
4) UNICOS DB
UNICOS DB template
UNICOS generator
6) PVSS programming
UNICOS PVSS components
7) DOC Final Report

6. UNICOS advantages
Provides PLC components that simplifies PLC programming
Provides PVSS components that simplifies supervision programming
Ensures coherence between documentation, PLC program and supervision program
Sets a STANDARD for cryo operation (lower costs….)

7. Sulzer-Linde TCF20 in CERN/BA4
At SPS BA4 there is a 4.5 K cryogenic infrastructure used last time about 8 years ago for COLDEX experiment. Upgrade in progress for 2 K refrigeration – UNICOS refurbishment is underway
Renovated compressor + elec. motor – run test done
Revised, labeled and qualified pressure control system / oil removal system
Cold box TCF20
2 K pumping groups recovered from AMS
New power supply panel for compressor station

9. LNL
Refurbishing underway to be completed in March

10. Cryogenic UNICOS collaboration for cryo refurbishing project

11. ALPI & LNL distributed UNICOS control system??

12. CONCLUSION UNICOS is a way to
simplify
STANDARDIZE the control approach
Better operation
1000 different ways to achieve your control goals... LNL will acquire the technology for its own uses with a modern and advanced tool!!
