TRANSCRIPT
The (prototype) C&V Framework component used for the SPD Cooling Control
A.Tauro, G.De Cataldo
The SPD cooling system control
The SPD cooling system is controlled by a dedicated Schneider PLC Process Control functions:
Common outlet pressure controlled by the liquid pump speed Common inlet pressure controlled by the compressor speed Operating cycle (Stop, Stand-By, Run and Recovery) General System Status (Alarm and Warning)
Distribution Control functions: the PLC doesn’t control the distribution lines except the OPEN-
CLOSED-LOCKED status of each loop.
The SDP cooling plant
In the rack on the left are located the pumps, the loop manifolds and all the relevant sensors and actuators to monitor and control the hardware.
In the right rack are located respectively:
The local operator panel that allows for a full monitoring and plant control; The plant operation from this panel doesn’t require any PVSS project; however it will be mandatory for its integration in the DCSThe Schneider PLC;

Actual communication scheme
In order to safely manage the communication between all the process PLCs of the ALICE experiment and the technical network, the TS/CV/DC group will install in the experimental cavern the Gateway PLC.

The FW C&V prototype component
PVSS 3.01 SP1 fwCoolingAndVentilation_0.14:
The JCOP has not yet officially released the component. It will be done in the next months after the collection of comments and suggestions from the 4 LHC experiments
“SPD.scy” file: Provided by the ST/CV group. Respects the
naming convention EDMS 585920. The time schedule for delivering to others sub-
detectors the scy file is not yet available, but it is under discussion in the ST/CV group. For the HMPID it is foreseen not before the end of June
No need to install OPC drivers
The FW C&V scy parser panel
The Plant and Loop configuration panels of the FW component
The synoptic panel of the SPD cooling plant
Each sub-detector can provide a similar synoptic panel with the representation of the cooling system and possibly the detector. It can be integrated either in the FW component, either in the monitoring zone of the FSM control panel

Cooling
•Once the plant is delivered, each detector has to integrate the plant control in PVSS using the C&V FW component. •It is still under the responsibility of each sub-detector to integrate the cooling FSMs in the DCS FSM. A possible hierarchy is presented in figure. Details can be discussed case by case. •In the ACC is under way the discussion of a project integrating, after the pre-installation phase, all the ALICE cooling plants in a unique control system.

Conclusions
The FW component and the scy file (provided by the TS/CV group) have been successfully tested with the SPD cooling plant;
For the HMPID the scy file will be released not before the end of June 06, and for the remaining cooling plants the schedule is being studied;
During the pre-installation, the cooling plant control has to be done at level of single sub-detector; therefore the corresponding cooling FSM has to be integrated in each DCS.
Each sub-detector has to prepare a synoptic panel with the representation of the cooling system and possibly the detector. This user panel can be used in both the FW component and in the FSM control panel.
