Workshop on the Use of Ethernet as a FieldbusCERN, 28 September 2001
Use of Ethernet in the control systems of the cooling and ventilation infrastructure
D. Blanc, M. C. Morodo ST-CV
ST-CV Control SystemsCommunication requirements for the LHC era:
The strategy:
To cope with the geographical dispersion of the CV processes --->
Networking
To integrate the existing heterogeneous environment --->
Openness
The retained control system solution -1998-:
Ethernet
A fully industrial standard control system architecture is taken as a reference Industrial approach
For the first time, a unique network solution at all the control system layers Ethernet

Cooling Completed 25 hosts
TOF, ATLAS, CMS, ALICE
Collaborations with Experiments:
Ventilation In preparation 20 hosts
Ventilation of surface buildings Ventilation of ATLAS & CMS experimental zones Cooling of ATLAS & CMS experimental zones
In progress (about 50 %)
Ready to start
In preparation
30 hosts 30 hosts 30 hosts
Cooling Starting 15 hosts
Altogether more than 150 hosts distributed over all the CERN sites
Conclusions
CERN Technical (Services) network has shown to fit the ST-CV control system communication requirements
– Very high availability and reliability– Network installation, administration and maintenance services
Performance Evaluation:
Thank you
Future Evolution:
Industrial control systems’ manufacturers are increasing their development on Ethernet TCP/IP
– The use of Ethernet shall be extended even more Field communication for distributed periphery
– Industrial fieldbuses (Profibus DP, FIP norm) keep their leadership for some more years yet
