Planning: Software

had a meeting recently (HV, LV, TSS, F. Glege)

for mid-2003 (SM0) : first prototype of DCS software system in PVSS

should include HV, LV, Temp.Monit., TSS, Cooling?,
communication with XDAQ and ECAL DAQ?
Framework with FSM, Partitioning,

test of this prototype during 2003

beg. 2004: production setup for the SM calibration at H4


during 2004, probably all resources needed for calibration
beg. 2005: first tests of a setup for full ECAL (maybe start with reduced size)

may have to find a location to do such a test

from mid 2005 on : install equipment and start testing of the full system

beg. 2006 : full system ready

Planning: Manpower

up to end-2003 : subprojects software covered by responsible groups, framework
covered, but I guess with substantial help/input needed (from Frank Glege, I guess)

end 2003 - 2004: have to shift manpower (1 person) to framework, probably from
TSS and Temp. monitoring

in 2005 - 2006 : would like to get help for the test and integration of full system,
also for the interfacing with the DAQ : 1 person (0.5 FTE ?)

Wishes/ Request / AOB
 we urge all subitems of DCS to look into PVSS (or a
possible interface such as DIM) as soon as possible
 when working with PVSS, follow rules when defining
data points
 please communicate, such as alarm types etc

HV issues
• they use CAEN PS. Supported by JCOP.
• Rome group will develop the HV PVSS application
• prototype should be ready for SM0
• they will have Labview as backup

LV issues
• exact system not yet defined ( in terms of hardware )
• planned to use DCUs (CCUs) to control the LVRs
• therefore: will use XDAQ
• therefore : will need PVSS - XDAQ interface
• hopefully a very first prototype ready for SM0

DSS issues
• a first prototype already used in 2002 (M0’)
• the Belgrade group will build the application
• should be ready for SM0
• need good communication with DAQ, in order to get information
from sensors integrated in PCBs
• needs communication with cooling
• sensors: as close as possible to final solution (2 sensors per
module)

Temp./Humid. Monit. issues
• a first prototype already used in 2002 (M0’)
• the Protvino group (together with ETHZ) will build the application
• should be ready for SM0
• needs communication with cooling (feedback ?)
• sensors : as close as possible to final solution :
• 10 temp.sensors per supermodule (4 on grid, 4 on screen, 2 on IN/OUT pipes).
• 1 humidity sensor per module

Cooling issues
• need to start discussion now
• I think at the moment they use Labview

Laser issues
• Need to start discussion now
• I assume they will have their own software (not PVSS)
• but at least we need software communication with the Laser
system in order to know hardware status

Communication with DAQ
• first tests for communication ECAL PVSS - XDAQ first half of
2003
• so hopefully ready for SM0
• As long as “J.Fay/J. Bourotte DAQ” is the run controller,
have to communicate : best solution: DIM
• the DIM name server would run on the central DCS station
• APIs exist for different platforms
• in PVSS (JCOP framework) DIM is integrated (as API manager, built in
via particular definition of data points)
• DIM could also be a candidate for other communications (eg. with
LASER)

Database/Archiving
• Probably will use PVSS archiving tools
• what other kinds of databases will be used by others?

FRAMEWORK issues
• A. Lister (ETHZ) just started to work on it
• hopefully first prototype ready for SM0
• with FSM, partitioning, alarm handling, XDAQ interface ...
• Note : planned that Alison leaves for CDF end 2003 (for some
time). See man power issues....
