• How to find the rank lowest for each student using a Select query?

  Hey I'm having a little trouble here
  
  I have this table
  
  
  Student - Grade
  
  John - 8
  Richard - 9
  Louis - 9
  Francis - 5
  John - 13
  Richard - 10
  Peter - 12
  
  Shades may vary from 0 to 20.
  
  Name - varchar (50)
  Grade - wide
  
  I'm trying to generate a SQL search to search for each rank lowest for each student.
  
  So far, I did:
  
  Select s.name, s.grade
  s student
  where s.grade = (select min (grade) of student)
  
  The result of this search returns me only the rank lowest of all ranks posted above, which is Francis - 5.
  
  I want to find the lowest rank, but not only for Francis, but for all students in the table.
  
  How do I do that?
  
  Thank you in advance.

  Ok

  Now we head into analytical SQL:

  with student as (select 'John' name, 8 grade, 'fail' result from dual union all
                   select 'John' name, 13 grade, 'pass' result from dual union all
                   select 'Francis',     5 grade,  'fail' from dual union all
                   select 'Peter', 12, 'pass' from dual)
  -- End of your test data
  SELECT   name,
           MAX (result) KEEP (DENSE_RANK FIRST ORDER BY grade) result,
           MIN (grade) min_grade
  FROM     student
  GROUP BY name
  

  Please note that I passed ;)

• Tasks of the DAQ Assistant

  How to create a task in the DAQ Assistant of LabView for one of our modules cDAQ without actually being connected to the cDAQ module?

  You can simulate a large number of instrument supported by DAQmx with Measurement & Automation Explorer.

  Right-click on the NOR-DAQmx devices and then create new, then simulate and choose from the list of supported devices.

  For the cDAQ chassis first then your module.

  Excuse me, but I don't have an English version of MAX and so I did not have the correct translation of command...

  When your simulated device is configured, ca use you it with the DAQ Assistant in LabVIEW.

• different type of terminals of elapsed time of the DAQ assistant

  I connected a digital relay to one of the outputs. I have installation wizard DAQ to operate a valve with the relay. Now, I want to control the valve to drive all... .lets say 20 seconds, until I stop the program. What I need, is to change the State of each 20 seconds. I tried to use the "Out of time", but when I try to connect 'elapsed time' 'Data' on the ass of data acquisition. It reports on the different types of data. What would be the way easy and clean to use a "timer" to operate a relay on a basis of time fixed and periodic? Thanks in advance!

• In Labview 8.5, what happens if the input signal exceeds the scope of the signal defined by the DAQ Assistant?

  Hi all

  This should be a pretty simple question, but I can't seem to find the answer online and currently do not have the functionality to test this:

  I'm using LabVIEW 8.5 and have a VI that imports data from sensor through the DAQ Assistant. In the configuration tab, there is a range of signal input. What happens if my sensor exceeds this range? I get a warning? The default value is the maximum (or minimum)? I was interested in writing a code to display an error that I approach the limits of this range, but did not know if I also need to include code to display an error if the scope is exceeded as well.

  Thanks for the help,

  Tristan

  Hello, Tristan,.

  The behavior depends on the selected range and the device you are using.

  If you are using a device with a single input range is valid, we will use this range, even if you set a smaller minimum and maximum in the DAQ Assistant.  So, if your device only supports ±10V and you set the range to ±8V, you will still continue to get valid data after your top sensor 8V until what you approach 10V.  When you reach the limit of the extent of your device, the output will be 'rail', and simply return the maximum value until the signal is less than the maximum value again.

  Note: A device that is nominally ±10V usually has a go-around (such as ±10.2V) which are usually specced in the manual.

  However, if you use a device with several ranges of entry then things become more complex.

  NOR-DAQmx player will choose the smallest range that entirely covers the interval you choose.  For example, suppose that your device supports the following input range: ±0.2V, ±1, ±5V, ±10V and you choose 0V - 3V as the range in the DAQ assistant.  The NOR-DAQmx driver will focus on the input range and the list of the entry lines that your hardware supports and choose the smallest encompassing the entire range that you set.  This would be the ±5V, because this is the only beach that contains up to 3V.  Thus, all between ±5V input signal is returned and none outside this range will be 'rail' to the maximum or minimum value.

  We do this because using small beaches make more efficient use of the resolution of the ADC.  So, we try to use the most effective range based on what you ask without picking up a range that will make you miss data.

  Let me know if I can clarify it more.

• How can I include all of the necessary files required for the DAQ Assistant create an executable file?

  I create an executable file to run on a computer that does not have LabVIEW.  The problem is that I am using the DAQ Assistant.  The hierarchy of the VI is big enough, and I do not know how to include all the required files to eliminate the error "the version of LabVIEw full development is necessary to correct the errors."  A picture of the hierarchy of the VI is attached.

  I think I'm missing something in the installation.  I'm downloading now the DAQmx.  I knowticed that all 7 of my missing Subvi are DAQmx * .vi

• New Daq with the Daq Assistant in the filtering code

  Hei,

  I have a NI USB-6225 DaqMx I used a couple of years. When I started with LabVIEW, I found the Daq Assistant to the best way to measure the voltage with my Daq etc. My company has purchased another DaqMx NI USB-6225 and now I have a big problem: the Daq Assistant in my old Vi does not work with the new data acquisition. I understand why there is this problem, but I do not know how to solve. I found this code on the forum who finds that Daq is connected:

  

  The problem is that Daq Assistant do not have an entry for it, and it gives me an error if I try to run the code with a different device than the original, I used when I created the code.

  

  Is there a way to solve this, so I don't have to convert all the Assistants Daq normal code?

  Hello again,

  two options:

  (1) as the old software is related to 'Dev1' you must rename your new device to this alias and skip/rename the old device (and lack).

  (2) rewrite your old software does not become is not dependent on the name of the alias for the data acquisition card...

  It's your choice!

• Precise triggering voltage input and output generation in the DAQ Assistant

  Hello

  I wonder if anyone has come across a simular problem with the synchronization of input and output voltage. I use a box 11 LabView and NI USB-6259. I have been using the DAQ Assistant to configure the input and output channel. In particular, my task is to generate a single rectangular "pulse" as the output voltage to drive a coil and once the pulse went to get a signal from a sensor of magnetic field and get a power spectrum. This means that the order and the time during which the DAQ Assistant is used is extremely important. For example, the output voltage channel must be opened first for 2 seconds. Subsequently, the channel of input voltage must be open for 1 second, in which the sensor signal is obtained and post-processed. Only after these tasks are performed in this order he can can be repeated in a loop until the experiment is over. I don't know how to trigger data acquisition assistants (one for entry) and the other for the voltage output correctly. Y at - it a trick?

  See you soon

  Hi Dave,.

  Thank you that I wired the error strings but the timing issue was unrelated to it. In the DAQ assistant, I simply had to choose the continuous aquistion of the 'samples' methods 'N-switch' for input and output voltage and all works fine now.

  Thanks again

• Is the DAQ Assistant compatible with LabView7?

  I am equipped with a LabView7 and a NI DAQ - 6015 Pad and am trying to monitor the temperature with two thermocouples. I searched some tutorials online, but most suggest using assistant DAQ, which is not listed in the section of my functions palette entry. I have downloaded the NOR-most recent DAQmx driver who is supposed to be compatible with LabView 7.x. I don't know if this means that it is compatible with LabView 7.0. I still do not see the DAQ assistant appear.

  Any help or suggestion (about DAQ assistant or how to program in LabView7 to solve my problem) is greatly appreciated!

  Thank you.

  It looks like the DAQmx latest version is 8.1 which will work with LV 7.0

• Calendar and the problems of data collection with the DAQ Assistant

  Hello NOR Developer area,

  I am a Novice of LabVIEW and have seen how helpful you all can be, and if I come to ask for your help.

  I'm having some trouble with a VI I built that specifies an input voltage, a SCB - 100 connected to a PCI-6031E and converts this tension in a temperature displayed on a waveform table. The goal is to give a constant reading of the temperature and display it in a chart for as long that the VI is running (and to reset the chart the next time the tracks of VI).

  The problems I've encountered currently are:

  -After a few minutes of the VI running, I get an error message 200279: tried to read samples that are no longer available. The requested sample was already available, but has since been replaced. (to the DAQ Assistant express VI).

  -I don't know how to change my chart so that the minimum value X is both during which the VI was launched and have the maximum X value increases with each iteration of the loop. Currently, I have the VI get the time system and contributing to the property node X scale. This worked for the graph of the voltage, but not for the temperature chart

  I appreciate those of you who took the time to read my post.

  Thank you all for your help.

  What property node is talking?
  I do not understand that many different data types. How can I go on the treatment of all the data?

  (Did you mean I should wire 'blue' data for mathematical functions rather than using the node property tension?)

  Sincerely,

  In fact, one of the nodes property.  I mean specifically the tension property node.  But in reviewing, I noticed the other nodes in property for the chart.  Just set auto-scaling to the X scale and that should take care of two of the nodes property (right click on the graph, X scale-> AutoScale X Scale).  I also recommend placing your mathematical functions in a Subvi to make things easier to read.  Attached, that's what I think you're after.

  I hope that these small tweaks will speed things up enough to avoid your error.  If this isn't the case, then we should begin to look at the design of producer/consumer model or take readings at the same time.  It might also be worth looking away the DAQ Assistant and DAQmx real screws.  But one step at a time.

• Using the DAQ assistant voltage vs time graph

  I'm relatively new to all Labview and terms and everything which affects programming. I've read tutorials and everything trying to understand things. One thing that I have a problem is the DAQ assistant. Now, if I wanted to place the DAQ assistant on the block diagram of labview and I have everything set up so that the voltage will travel in the DAQ hardware, how would I set up my block diagram so that I can get a graph of voltage vs time in which data begin recording until the voltage reaches a certain tension I was inputing and change such as 30 or 40 volts. The data will also stop recording when the voltage reaches the same number. I also want to be able to multiply the number of voltage coming out a number that I can change myself before it is graphed over time. Example, I mean the voltage to start recording when he reached 40 volts. Now when the voltage comes out of allows it to DAQ assistant say he is somewhere read 10 volts and the number I want to multiply by 5. So, I want to be able to multiply the voltage by 5 and then since it will be 50, it would begin graphing this number over time.

  You would need to have a Boolean value which controls whether the (amplified) voltage is greater than N.

  If so, he would send this value to a graph, if not, the tension would not get graphically.

  Here is an example: (do not try to copy this code exactly, because it does not use a signal, but rather a whole number that is being created)

  

• How to find the device ID?

  How to find the device of my CAN ID card and RIO (or card for something else)?

  I use MAX 4.5 and LabView 8.6.

  Thank you.

  Open MAX and go to the section:

  My system > devices and Interfaces > NOR-DAQmx

  It should list all your DAQ devices and say something like

  DAQCard-xxxx: "Dev 0.

  DAQCard-xxxx: "Dev 1.

  etc.

  Just look at your device

• There is no entries or exits on the DAQ assistant to connect to

  Hello world

  I'm new to labview and have encountered difficulties with the DAQ assistant.  I'm under v8.0, v8.7.1 OR-DAQmx labview and have an acquisition data PCI-6224 installed.  It seems that every time I have let down the DAQ assistant (assistant of the instrument and data acquisition simulated has the same question) on the block diagram and configure it, it don't y no input or output that I can wire a control or an indiactor to.  Y at - there a step I'm missing somewhere?

  Thanks in advance!

  Try to repair the DAQmx driver through control panels and see if that solved the problem.

  How to uninstall or repair OR software?
