Minutes 26/3/03 and Status SR1
Present Action
list
For your attention
There will be a clean room course at Cern next week and people
planning to work in the clean room are encouraged to attend it.
ItŐs free and reasonable in length
1.) General/Global SR1 DCS (Helfried/Richard)
DCS group wants to use the ID parts of the DCS to test the
global DCS, will setup infrastructure for global system. DCS PCs are
ordered/available.
Slava currently helps with OPC server expertise, later
possibly with the cooling system.
Database handling will come in a second stage.
It was discussed if we should merge the environmental
monitoring for thermal screen LCS and cooling LCS as they are to be very
closely integrated anyway. Steinar/Richard/Heinz prepare WP description for
cooling/thermal screen DCS.
User interface for LCS is part of the group making the LCS DCS.
DCS group can provide samples.
Need to list which LCS station is on which level (to be
followed up by Richard H /Heinz)
Software interlocks and interrupts from substations go
through global system.
2.) CIC (SR1 plant & infrastructure monitoring) (Fernando,
Balasz)
at the moment includes: Rack monitoring, (monitoring only,
no interrupt), Temperature and humidity monitoring in the different SD1 room.
This is in progress now.
Should include 1 pressure sensor in clean room.
For later: monitoring for venilation system,UPS etc....
Fixation of NTC sensors in racks needs to be worked out
(RIchard to ckeck)
The first version should be avilable in 4-6 weeks for
trials
3.) SCT power supplies DCS (Ewa, Pamela, Heidi)
in progress now. Based of DCS from SCT LVS for power
supplies to ELMB.
Dedicated special ELMB software is being developed for the
crate controller. The LCS part will follow DCS standards.
Present status:
-
we can send commands to the ELMB and read back from the buffer
-
we can send simple control messages
-
we control and monitor globally the HV and LV channels as well as
individually. For the control we are
using as a guideline your document
describing the run state transitions. Heidi
has prepared a table that will
be sent to you soon together with an
update of the parameter list
discussed already with Pamela and Ewa.
-
we are starting to work on configuration of the crate and we have decided to
base it on an ASCII file for the moment
and in the next future on XML files
that could be easily imported in a
database.
-
Next we will start to deal with error messages.
-
Of course next week we will try all of this on real HV/LV modules.
-
Our project is a distributed project is made following the JCOP framework
rules, thanks to the close contact we
keep with Fernando.
-
We are also in contact with Abdel, next week he will be at CERN and we
hope to test some DDC commands at this
stage
Datastorage
through PVSS archieve, DCS group will explore possibility to use Oracle.
This should be done together with CIC data storage.
4.) TRT DCS (presented by Fido)
mainly effort by Krakow group now. The first part of the
TRT DCS for SR1 will also be power supplies (Hv). Fido will prepare timeplane
with Krakow group next week for DCS in SR1.
see attached pdf file on TRT SR1
DCS.
5.) Present SR1 Status
a.)
Electricity/Network
Installation of electricity and network progresses well. All
AC outlet boxes are installed and most are cabled
All network outlet boxes are installed and cabling started
b.)
Control
Room
The airlock from control room to assembly area is
installed. Also the window from control room to test area is installed. The airlock
still needs to be painted.
The network outlets in the control room have been slightly
group for simpler installation (same number as before but grouped to one group
of outlets on each wall)
We will order 4 small local UPSs to serve some of the
PC located in the control room.
c.)
Clean
Room
Two roof panels in the airlock have been replaced by
Schulthess. The installation drawings for the cable trays are ready but we
still wait for the quote.
For AC local distribution we will order five standard
distribution rails in to be fed by the 220V/25A outlets in the assembly and
test area. They will be wall mounted.
d.)
Rack
area
The refurbishing of the racks in the rack area has started
by Per & Richard this week. This will include
= adjustment of ventilation side panels to fit our
specified rack layout and rack distribution
= cleaning and check of water cooling plumbing in racks
= mounting and connection of heat exchangers in water
cooled racks
= preparation for rack water cooling commissioning by ST
(commissioning of pumps, heat exchangers, control)
e.)
Access
control
We received the plan for the access control.
Access control (card readers) will be installed on the
entrance door to the control room (from the rack area) and on the main clean
room entrance through the airlock. They will be connected to Ethernet and
access check is provided by a database. The quote and installation plan is
available.
The mode of operation is
= access with your Cern card
= access is given on an individual basis for a specific
period of time.
= the access database is updated 4 times daily
6.) Follow ups: Supply of dry air and clean compressed
air
