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….)

K. Brodzinski - CRG HiLumi #1_2013.01.31
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
Cold box TCF20
2 K pumping groups recovered from AMS
Renovated compressor + elec. motor – run test done
New power supply panel for compressor station
Revised, labeled and qualified pressure control system / oil removal system

TCF20 @ LNL
Refurbishing underway to be completed in March 2013......
Cryogenic UNICOS collaboration for cryo refurbishing project
ALPI & LNL distributed UNICOS control system??
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!!
