• How many channels can I write to a file with the data Module write (Dasylab 12.00.00)?

  I would like to write data from a large number of channels (up to 128) in the same file. Thanks to the write data module, I have up to 16 channels only! The only solution I found is to save data in different files 8... Is there a solution for this problem? I use DASYLAB V.12.00.00. Thank you

  You can use the multiplexer unit, this will allow you to compress the 16 channels in 1 which saves up to 256 channels in a single file.

  In the module of the file to write, you can then select options and, under the "input Type", select the values of mixed singles.  You will then need to define how many channels in each entry will receive.

• DASYLab how to write data to a file every 15 minutes

  Hi all

  I use dasylab and datashuttle/3000 to record data. What I want to do is to write data to a file every 15 minutes. I use the milti-file, which can write data to the file diffenret, but how do I control the timing, as the journal data every 15 minutes automatically.

  The other problem is that I use FFT analysis of the frequency spectrum. How can I determine the value of frequency where the peaks that happens.

  Thank you

  Write less data in the file that you have collected requires the reduction of certain data.

  There are three techniques to consider.

  With an average or an average of block - both reduce the data by using a function of averaging, defined in the module. To accomplish the reduction of data, choose block or RHM mode in the dialog box properties, and then enter the number of samples/data values that you want to reach on average.

  Average - when you reduce the data, you also should reblock data using the block length of the change in the output parameter. For example if you enjoy at 100 samples/second with a block size of 64, the average module configured on average, more than 10 samples will take 10 times longer to fill a block. The initial block represent 0.64 seconds, the output block represent 6.4 seconds at a sampling rate of 10 samples/second. If you change the size of output in one block, the program remains sensitive.

  Average block - average values in a block against each subsequent block, where the average is based position. The first samples are averaged, all second samples are average... etc. The output is a block of data, where each position has been averaged over the previous blocks. This is how you will be an average data FFT or histogram, for example, because the x-axis has been transformed in Hz or bins.

  Second technique - separate module. This allows to reduce the data and the effective sampling rate jumping blocks or samples. For example, to reduce the data in 1000 samples / second to 100 samples per second, configure the module to keep a sample, jumping 9, keep one, jumping 9, etc. If you configure to skip blocks, you will not reduce the sampling frequency, but will reduce the overall amount of data in a single block 9, for example. It is appropriate for the FFT data or histogram, for example, to have the context of the correct data.

  Finally, you can use a relay and a synchronization module module to control. For example, to reduce a sample data every 15 seconds, configure a generator module of TTL pulses for a cycle of 15 seconds of time. Connect it to a Combi trigger module and configure it to trigger on rising and stop the outbreak directly, with a trigger value after 1. The trigger output connects to the X of the relay command input.

  In addition to these techniques, you can change the third technique to allow a variable duration using a combination of other modules.

  Many of these techniques are covered in the help-tutorial-Quickstart, as the data reduction is one of the most frequently asked questions.

  In regards to the FFT... use the module of statistical values in order to obtain the Maximum and the Max Position. The Position of Max will be the value of the frequency associated with the Maximum value. The output of the statistics module is a single sample per block. Look at the different FFT sample installed in the worksheet calculation/examples folder.

• How to write data from the acquisition of data in NetCDF format?

  I connect to a set of data from the sensor through the DAQ assistant and want to write all data in NetCDF format. I have the required plugins installed, but still can not find how to do this.

  Or the labview can only read the netcdf files, but cannot write it! Please let me know if there is any other way out. I have looked everywhere but could not find something useful!

  Thank you

  Hey,.

  Sorry, the sheet in effect only allows to read NetCDF files, not writing to the NetCDF format.

• global variable functional to read and write data from and to the parallel loops

  Hello!

  Here is the following situation: I have 3 parallel while loops. I have the fire at the same time. The first loop reads the data from GPIB instruments. Second readers PID powered analog output card (software waveform static timed, cc. Update 3 seconds interval) with DAQmx features. The third argument stores the data in the case of certain conditions to the PDM file.

  I create a functional global variable (FGV) with write and read options containing the measured data (30 double CC in cluster). So when I get a new reading of the GPIB loop, I put the new values in the FGV.

  In parallel loops, I read the FGV when necessary. I know that, I just create a race condition, because when one of the loops reads or writes data in the FGV, no other loops can access, while they hold their race until the loop of winner completed his reading or writing on it.

  In my case, it is not a problem of losing data measured, and also a few short drapes in some loops are okey. (data measured, including the temperature values, used in the loop of PID and the loop to save file, the system also has constants for a significant period, is not a problem if the PID loop reads sometimes on values previous to the FGV in case if he won the race)

  What is a "barbarian way" to make such a code? (later, I want to give a good GUI to my code, so probably I would have to use some sort of event management,...)

  If you recommend something more elegant, please give me some links where I can learn more.

  I started to read and learn to try to expand my little knowledge in LabView, but to me, it seems I can find examples really pro and documents (http://expressionflow.com/2007/10/01/labview-queued-state-machine-architecture/ , http://forums.ni.com/t5/LabVIEW/Community-Nugget-2009-03-13-An-Event-based-messageing-framework/m-p/... ) and really simple, but not in the "middle range". This forum and other sources of NEITHER are really good, but I want to swim in a huge "info-ocean", without guidance...

  I'm after course 1 Core and Core 2, do you know that some free educational material that is based on these? (to say something 'intermediary'...)

  Thank you very much!

  I would use queues instead of a FGV in this particular case.

  A driving force that would provide a signal saying that the data is ready, you can change your FGV readme...  And maybe have an array of clusters to hold values more waiting to be read, etc...  Things get complicated...

  A queue however will do nicely.  You may have an understanding of producer/consumer.  You will need to do maybe not this 3rd loop.  If install you a state machine, which has (among other States): wait for the data (that is where the queue is read), writing to a file, disk PID.

  Your state of inactivity would be the "waiting for data".

  The PID is dependent on the data?  Otherwise it must operate its own, and Yes, you may have a loop for it.  Should run at a different rate from the loop reading data, you may have a different queue or other means for transmitting data to this loop.

  Another tip would be to define the State of PID as the default state and check for new data at regular intervals, thus reducing to 2 loops (producer / consumer).  The new data would be shared on the wires using a shift register.

  There are many tricks.  However, I would not recommend using a basic FGV as your solution.  An Action Engine, would be okay if it includes a mechanism to flag what data has been read (ie index, etc) or once the data has been read, it is deleted from the AE. 
  
  
  There are many ways to implement a solution, you just have to pick the right one that will avoid loosing data.
  

• How can I save data in text format

  How can I save data in text format in labwindows cvi

  Hello

  If your data is in a table, the easiest is to use the ArrayToFile function.

  Automatically, it creates a file and puts your data in it depending on the size you provide.

  If you have individual samples you need to write from time to time, you can either collect them in a table and then use ArrayToFile or open a file with fopen and write them as they are acquired with fwrite.

  Hope this helps,

• How constantly write data in a txt file

  Hello
  first of all, sorry for the bad English, but I have a problem to write data continuously to the txt file... I have a chart 2D with values based 2 sliders (sliders values) and some functions I want to interpolate the value by using the bilinear method... and after that the value of the sliders, interpolated value and the value of the closest points, I want to write to a file txt... for every 2-3 seconds perhaps, it would be ideal to be formatted as ::
  x y f f1 f2 f3 f4
  ..   ..  .. . .. .   ..   ...  . ..
  ... ...  ..    ...   ...   ...   ...

  but... first of all I have a problem with writing data, because every time he deletes old data and simply write a new and it is not horizontal... I am very very new to this (it's obvious) and any help will be very grateful 
  Thank you

  

  Diane beat me to it, I made a few changes to your code, so I'll post it anyway.

  

  As proposed, please go through the tutorials.

  I added an entry to the worksheet at the end node just to show it can be done at the end so. Table of building on a while loop is not very efficient memory, but it's just to show you what can be done. If you plan to go this route, initialize an array and use the subset to the table replace.

  All the best.

• Write data to data acquisition in a .txt or .csv file

  Hello

  I want to write the DAQ data inot a file .csv or .txt, so I'll try to handle 'Write in a spreadsheet file', can cause I can record data in all formats. My concept is that data acquisition data will save in a file continuously when I press the button IT and when I press STOP button then it will ask the user to save the file.

  I have attached the file VI.

  But my problem is that every time he asks me a new file even if I put the file append as true.

  All of the suggestions.

• Output formatting in a sql

  Hello

  I have 4 columns, I need the output format using carriage returns between values and removing the label for nulls, such as only the columns filled with values are displayed:

  Name: emp.first_name

  Medium: emp.middle_name

  Name: emp.last_name

  Address (line 1): emp.ext_contact_addr1

  for example: -.

  If the name is null then output would be

  Middle: Thomas

  Family name: James

  Address (line 1): 10 william st

  If the name is null, then output would be

  First name: Tessa

  Family name: James

  Address (line 1): 10 william st

  etc...

  Please help me.

  Hello

  Here's a way

  SELECT LTRIM (NVL2 (emp.first_name

  , ' Name: '. EMP.first_name

  NULL

  )

  || NVL2 (emp.middle_name

  , CHR (10) | ' Average: ' | EMP.middle_name

  NULL

  )

  || NVL2 (emp.last_name

  , CHR (10) | ' Last name: ' | '. EMP.last_name

  NULL

  )

  || NVL2 (emp.ext_contact_addr1

  , CHR (10) | ' Address (line 1): ' | EMP.ext_contact_addr1

  NULL

  )

  , CHR (10)

  ) AS output_string

  WCP

  ;

  Using NVL2 like this, the label for each line gets concatenated only if there is some data to go with it.

  If the name is NULL, which means that the output_string will begin with a character of new line (which is CHR (10) on my system, you may need to change this).   I used LTRIM to remove this first newline character, if there be one.

  You can also consider the results of unpivoting so that you have between 0 and 4 lines in the result set for each row in the emp, with 4 items on separate lines.

• Question output formatting

  Hello community! Sorry, it's so rudimentary. Can anyone offer advice on how to better format the output of the below? As it is, it prints it just without formatting - I want out as the output format-table and I would have zero decimal places in the output of Write-Host $CurrentItemHdd.CapacityGB.  Thank you!

  foreach ($VmItem to $MyVms)

  {

  $CurrentItemHdd = get-disk hard - VM $VmItem

  Write-Host $VmItem.Name $CurrentItemHdd.CapacityGB

  }

  To create an exit in your PowerCLI script like the Format-Table output, you must create an output object. There are several ways you can do. One way is to use the PowerShell New-Object as shown in the below script cmdlet. The properties in the New-Object cmdlet output are not classified. That's why I redirect the output to the Select-Object cmdlet to order.

  Your original script will generate a table for the CapacityGB property, if a virtual machine has more than one hard drive. That's why I introduced a second foreach to browse the hard drives. Because you probably want to know that CapacityGB belongs to the hard drive, I added the property 'hard drive '.

  [Math] .NET: Round() function is used to supplement the CapacityGB to zero decimal places.

  The character '&' at the beginning of the script and the scriptblock around the script are necessary to allow to channel the output of the script to another cmdlet as Export-CSV. foreach is not a cmdlet, and therefor you cannot use the out of foreach in the pipeline without using this trick.

  & {foreach ($VmItem to $MyVms)

  {

  foreach ($CurrentItemHdd in (Get-disk hard - VM $VmItem))

  {

  New-Object PSObject-property @ {} TypeName

  VM = $VmItem.Name

  "Hard drive" = $CurrentItemHdd.Name

  CapacityGB = [Math]: Round($CurrentItemHdd.CapacityGB,0)

  } |

  Select-Object - property, CapacityGB VM, 'Hard drive'

  }

  }}

• ud32 output format

  Hi all
  
  We use ud32 to test service using fml32 buffer. One of the result field is a double, when the value of the field data are displayed in exponential format.
  
  Is it possible config output format? I don't want no exponential format. Its config possible in ud32?, it's a shell config?
  
  I thank in advance.

  Hello

  Unfortunately, there is not a way to control the release of ud/ud32. It just uses Fprint() which uses the format string "%g" to print floats and doubles. What you're asking for sounds reasonable. As an alternative it would be not difficult to use a script (awk or other) to convert the exponential value to format numbers in no exponential format.

  If you really need, I would suggest opening and enhancement with the Oracle customer support request.

  Kind regards

  Chief Architect of Oracle Tuxedo

  PS ud/ud32 is really a pretty simple utility and it reproduce yourself would not be a lot of work.
