Temperature&humidity
control programm - burn_T&H.vi
:
1. Login to PC(drache) in Linux mode as lhcb user
2. Start LabView. Open shell and type "labview" : hep/lhcb> labview
3. Connect Point Six to the port or check it if it's
connected. Check that power supply for Point Six is switched-on.
IMPORTANT: Do not change any settings in VISA
Configuration
if you have no knowledges how to configure it, then ask before any
changes.
4. Open VI: either pull-down menu or path: /home/hep/lhcb/labview/burn/burn_T&H.vi
5. burn_T&H.vi:
1) Press "Run"
- click on symbol ("arrow") at
the top of the VI
2) Set
an "Interval
between readings" (in minutes)
3) Press "START MEASUREMENTS"
button,
After pressing of this button must appear a green light -
indicator "Point Six
initialised-green"
- Otherwise again check connection
between Point Six and port, and make sure that VISA is working.
In 15-20 sec after pressing, must appear values of current temperature
and humidity.
At the plots you can see an
average values for temperature and humidity versus number of run.
If you will leave it at this step then
the VI will read-out all TEMPERATURE&HUMIDITY sensors each **
minutes
in accordance with "Interval between readings" which was set by
you.
Saving of the
data:
After each reading the
burn_T&H.vi creates a txt file in
/home/hep/lhcb/labview/longterterm_th/ directory with the following format inside:
sob
timestamp,1110990774
tprobe,9,27.06,29.30
tprobe,8,26.00,32.49
tprobe,7,26.87,27.38
tprobe,6,27.06,27.65
tprobe,5,27.81,28.01
tprobe,4,27.87,26.73
tprobe,3,26.75,29.26
tprobe,2,26.81,27.34
tprobe,1,27.06,27.04
eob
where is written temperature&humidity for all nine sensors .
First row (after "tprobe") corresponds to the number of the sensor,
next row corresponds to the temperature and last to the humidity of
this sensor.
The name of the txt file is written in
the following format: MMDDYY_R.txt
where R is a number of run
For example:
"031605_7.txt"
means that this txt file was created March 16th, 2005 - "031605"
it was seventh reading of the
temperature and humidity - "_7",

CANbus control programm -
CANbus.vi :
1. Switch-on CANbus setup in lab 36H26
2. Login to PC(drache) in Linux mode as lhcb user
3. Start LabView. Open shell and type "labview" : hep/lhcb> labview
4. Open VI: either pull-down menu or path: /home/hep/lhcb/labview/burn/CANbus.vi
5. CANbus.vi:
1) Press "Run"
- click on symbol (arrow) at
the top of the VI
2) Choose:
- "all channels set" - will set the same voltage to all
channels;
- "individual set" - will set a voltage
to channels as you filled into array;
For that set a switch in right
direction
3) Write a
voltages which you want to set in channels
4) Press "Initialize"
button,
it has to return into shell
where you are running labview the following:
errno = 0
init ok
0
errno = 0
Rampe = 0
Switch channels on = 0
errno = 0
Rampe = 0
Switch channels on = 0
errno = 0
Rampe = 0
Switch channels on = 0
errno = 0
Rampe = 0
Switch channels on = 0
what means that CANbus is initialized.
5) Press "Set Voltage"
button
IMPORTANT:
Press this button ONLY when there is a green
light (indicator with an inscription "Ready ?"),
what means that programm is ready to set a voltage and waiting when you
will press "Set Voltage" button
6) Set an "interval between
readings" (in minutes)
7) Press "Read V&I"
button
After pressing of this button the front
panel of the subVI "readVI1.vi"
will automatically appear at the screen where you can see in
on-line the voltage and current at all
channels, reading goes step by
step from first channel of Module 1 to last channel of Module 4.
After finishing of reading the front
panel of this subVI will
automatically disappear, and voltages and currents
for all channels
will be transmitted and can be seen at the front panel of the "CANbus.vi"
If you will leave it at this
step then this VI will read-out all channels of the CANbus each
** minutes
in accordance with "interval between readings" which was set by you.
How to set a new voltage without stopping of the VI:
1) Press "Stop reading" button
2)
Write a new voltages
3)
After appearing of the green light press "Set Voltage" button
4) Press "Read V&I" button
Saving
of the data:
After each reading the
CANbus.vi creates a txt file in
/home/hep/lhcb/labview/longterm_can/ directory with the following format inside:

where is written all voltages and currents for all channels of four's
modules.
The name of the txt file is written in the following format: MMDDYY_V_R.txt
For example:
"031605_1_2.txt"
means that this txt file was created March
16th, 2005 - "031605"
it was first settings of the
voltage - "_1",
it was a second reading for
such voltages - "_2"
If you will change a voltages after first set, then the first
file with a second settings
will have the following name:
"031605_2_1.txt"
