several parcels of a 1 d array

• Insertion of several strings in a 1 d array

  Hi all

  I am a beginner new to LabVIEW, so go easy on me. I tried to do for far too long and I thought I'd give forums a shot. I'm taking a picture 2D channels and their entry in a 1 d table. Sounds pretty simple, but for some reason, I just can't get it. The table then feeds into a ring of text. Thus, for example, say I have a table of dimensions 4 x 2 [a b c d e f g h], the output I want is a 1 x 2 [abcd, efgh] matrix. However the table could be 4 x 4 or 4 x 6, so this is not fixed. The ring of the text allows the user select among the options (2 in this case).

  I hope that I have described my problem clear enough for people. Taking the strings in the 2D array and put them in a chain are as close as I got what I want. I also tried the table to a spreadsheet string, but he gave me a long string. Unless there is something blatantly obvious that I'm missing, could someone give me some advice? Also, I would just add that everyone telling me to go read the tutorials, etc. of source material. Believe me, I have. Carefully.

  I have included a picture of the section of code that I'm trying to make it work. And Yes, I realize that it will not be anything to the ring of text entry right now, which is currently just how I saved it.

  Replace the while loop with a loop For.

  Do not use the subset of the array, simply use the tunnels of automatic indexation.

  Use the concatenation of strings on your table 1 d and you will have a single string.

  Use the automatic indexation on the exit tunnels and you will have a table 1 d of these channels.

  (You may need to convert the 2D table before feeding it into the loop For).

• In real time several parcels using the graphics buffer XY?

  Hi all. My teacher wanted to add a second set of data to the plot in real time, I've created in my vi. I was able to trace the two sets of data, but not as two plots. I managed to add a second point of y to the plot. What is the appropriate method for the use of a buffer of xy-graphic inside a loop to draw two separate parcels?

  The idea is that once I have two plots I can adjust a second axis and adapts the second group of data to this axis.

  Thank you!

• several functions of transfer in a graphic bode

  How can I trace transfer several functions in a single graphic bode? Can someone point me to an example

  Li,

  First of all, if you use the mouse to grab the top of the legend of the plot and "pulling" upwards, several parcels will appear.  The graphic node will wait for multiple entries.  This solves your problem, or is it more than that?  If not it would be useful that post you the code you have so far.

• several devices with daqmx

  I did not use daqmx much, so I have a very basic question. I want my program to support only a usb data acquisition specific (6509) and also to find the associated bit device name is important to how it is listed on the PC.

  I have a Subvi, which searches the computer for the usb-6509 automatically and displays the name of the device. My question is, where to connect this device in daq MX name? Is the terminal 'name '?  Clearly, this isn't as a resource of visa.

  Please, see the following and let me know if I'm right.

  Thanks, gurus!

  The device name can be used as a string.  Which means that if you take the name of your device and concatenate ' / port0/$line0 "you have a new string with the name" Dev1/Port0/$line0"that can then be used the physical channel for a task.  If you need several channels, and then create an array and use the channel string flatten to bring in a scalar data type.

• Error update Firmware on PS-100F Array

  Hi team,

  I have two paintings PS-100F. I've updated a table 3.3.1 in 4.0.7 using ftp and serial cable. However I'm unable to update the second table. I can copy the .tgz OK: it is an ls:

  FTP > ls

  I removed the .tgz with ftp and restarted table. I downlowded and copied to the top a new file several times, so to reboot the array without result. I don't know how or what to remove to create more space

  It's the ls of the table updated successfully. It has a different content of the problomatic one above.

  This is probably something obvious, how to create more space?

  Thank you

  You have transferred the kit in 'ASCII' mode or text.   You should use BINARY mode.   Remove this file kit, and then type BIN before starting the transfer.

  In addition, Yes, you must remove these files from the two base.  This will free up the space you need.

• Plot 2 functions of different dimensions

  Hi guys,.

  For example, I have the vectors:

  1 [2 4 6 8 10] = x, y1 = [4 7 8 9 4]

  x 2 = [1 2 3 4 5 6 7 8 9], y2 = [2 4 5 6 7 5 8 8 7]

  I want to plot (x 1, y1), plot(x2,y2) on the same graph. Note that the length of the two different plots.

  I tried to use the XY graph, but there is no way to do this and the waveform graph, requires an initial value of x and delta x, which are not the same in this case.

  Thanks for any help.

  If you hover over the terminal of the BD of the XY graph he shows you how to get several plots, just to build an array of individual parcels of XY.

  

• Shared Variable (published network) communication

  Hi all

  All day I was hitting my head with variable communication shared between RT host and the host computer:

  I basically tried to pass an array of the host of the CR to the host computer. For this I used a published shared variable of network type Array U64. I used this link to help me understand usign shared variable communication

  http://www.ni.com/white-paper/4679/en ...

  I also activated RT FIFO. Now in the city that link the information given on the use of FIFO of the single element or Multi element FIFO

  "By enabling real-time FIFO, you can choose between two types of compatible FIFO slightly different variables: the only element and the buffer insurance program. A distinction between these two types of buffers, it's that the only element FIFO reports no warnings on positive or negative overflow conditions. A second distinction is the value returned by LabVIEW when several readers read an empty buffer. Several readers the only element FIFO receive the same value, and the only element FIFO returns the same value until a writer writes back to this variable. Several readers of a FIFO empty array each get the last value that they read from the buffer or the default value for the data type of the variable, if they have not read before variable. "

  I had read the content above a 100 times, but still I'm not able to get a clear picture of the difference and when to use which option. So I decided to take the text and tried to try something for me.

  I had a loop in the reception of RT who writes arrays of 3 different elements in the 'network published variable shared'. Now when I use the option of multi element with "number of berries as - 2" I am able to read tables separates one by one in the host computer (as you can read a queue in general).

  Now when I used the option of single element for the RT FIFO with 1 UN editable table option, only the last table written in the 'shared variable published network' is read in the host computer.

  This seems absolutely ridiculous as if this is the case, then what is the purpose of creating the "buffer". For testing purposes, I had put the buffer in 5 tables.

  In fact, I have only a single author (written in loop in the reception of RT) and a reader (new looping in the host computer). So I don't know even if I need option of the RT FIFO for the published network shared variable.

  I'm sorry for the long message but I've reached the limits of going around in circles waiting to type somewhere

  I know I made a mistake stupid somewher or it miss me probably a clear simple trick but don't know what it is...

  I request some clarification... In fact I posted a little while earlier today so ... bind - http://forums.ni.com/t5/LabVIEW/RT-Host-to-Host-computer-communication/td-p/2348130 )

  any help would be appreciated

  See you soon

  me

  Hello

  I think that the difference between these two types is clearer by using LabVIEW:

  "

  Activation of the FIFO in real-time

  You can activate the FIFO in real-time to a shared variable since the page FIFO in real-time of the properties of the shared Variable dialog box. Check the box Enable the FIFO in real-time in a deterministic way share data using the one element or several elements FIFO.

  Single element FIFO

  One FIFO shares the most recent value of the data. The shared variable overrides the value of data when it receives a new data value. Use this option when you need only the most recent value. Configure the size of the elements of the array or the size of the waveform for the FIFO buffer, if you select a table or a waveform data type.

  Several elements FIFO

  A FIFO multi-elements implements buffer the values shared by the shared variable. You can configure the size and elements of the buffer FIFO to match the parameters of buffering to use of the Variable page, or you can configure a custom size for the FIFO and FIFO elements.

  Note  For single item both multi-elements FIFOs, if the variable contains data table or a waveform, you must configure the size of the elements FIFO equals the size of the data to share. If the network buffer both the RT FIFO are enabled, the network buffer should be at least as big as one of the elements of FIFO. Sharing data smaller or larger that the specified length results in a memory allocation which affects determinism.

  Note  Waveforms contain variant of varying size that are not compatible with real-time FIFO. Therefore, if you enable the FIFO in real-time on a shared variable that contains the waveform data, the item variant waveform data does not transfer.

• Comprehensive functional LV2 only inits element 0

  HI - using a global functional with several parallel loops - it contains an array of clusters as its data.  The installation program is the structure of your database read/write (attached).  When you start the application, I initialize an array of 12 elements of clusters and write on a global scale.  Yet, when I try to write to the data afterwards, it seems that the only element that is not dimmed, is element 0 of the array, so any time I write to any other element, data don't "stick".  Is it because the USR does not know what size to?  How do I code around that?  I tried to add one for the init for the World Cup without result. I have used this in LV 7 without any problems, but in LV2011 switch - attached are two copies thx

  This may sound a little silly, but are you sure that you have somewhere a copy of this VI laying around in your diagram that is configured to write to the buffer? Might be hidden behind another node or a structure?

  The VI se seems to work exactly as I would guess given the triviality of it, it is only logical.

• Add paragraphs with text

  Dear patients, caregivers,

  I want to "empty" the content of a table in a series of paragraphs. Two problems in my script:

  -Insert a \t TAB inserts a line break

  -items are not placed in successive paragraphs, but at the beginning of the flow - so sense reverse order and not own paragraphs

  

  // write array to multiple paragraphs
    var items      = new Array ();
    var nItems, pgf, textLoc, oDoc; 
    items = ["Århus", "Çedille", "Dandy"];
    nItems = items.length;
    oDoc = app.ActiveDoc;
    
    pgf = oDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;  // get first pgf in flow
    textLoc = new TextLoc (pgf, 0);  
    for (var i = 0; i < nItems; i += 1) {
      insText = items[i];
      oDoc.AddText (textLoc, insText + "\t" + insText); // \t insert a NL...
      oDoc.NewSeriesObject(Constants.FO_Pgf, pgf);  // add a paragraph
      pgf = oDoc.NextPgfInFlow;
    }
  
  
  

  Hi Klaus,

  Just change your last line of

  oDoc.NewSeriesPgf (TFP);

  TO:

  PGF = oDoc.NewSeriesPgf (TFP);

  that should do it.

  If you point directly to the new portfolio.

  completely:

  write table in several paragraphs

  var elements = new Array ();

  var nItems, textLoc, FMP, oDoc;

  items = ['Århus', "Cedilla", "Dandy"];

  nItems = items.length;

  oDoc = app. ActiveDoc;

  PGF = oDoc.MainFlowInDoc.FirstTextFrameInFlow.FirstPgf;  get TFP first rate

  for (var i = 0; i)< nitems;="" i="" +="1)">

  textLoc = new TextLoc (BMP, 0);

  insText = items [i];

  oDoc.AddText (textLoc, insText + "\x08" + insText); \t Inserts a NL...

  If (i< nitems="">

  PGF = oDoc.NewSeriesPgf (TFP);                       Add a paragraph

  }

• Necessary for ESXi 5.0 RAID?

  Hi all

  I am quite new to this VMware and it's our first test of society on the implementation of the VM solution to our test environment.

  So please be generous if my question is redundant or I'm a bad advice.

  Our server is HP Proliant DL380 G5 server, and we bought the license VMware Essential Kit.  (installing ESXi 5.0 planning)

  As most of you already know, HP servers have this thing SmartStart which helps the user RAID disks before installing so that cases of dysfunction of a disk, the mirror will do its job until the fix.

  But when I was reading the other articles, it is said that esxi will not recognize software RAID?

  Also, no ESXi have some type of built in resources distribution system that allows virtual machines to function even if one or two hosts readers a malfunction?

  Corrections, suggestions and questions are welcome.

  Moreover, since it is the test environment, HP box is the only host (about 3.8 TB) and we intend to run about 4 ~ 5 VMs.

  Thank you

  Welcome to the community,

  most of the DL380 G5 models come with a built in P400 SmartArray RAID controller, which is a hardware RAID controller supported. The RAID functionality is completely transparent for ESXi in this case (for example, rebuilding after a fialure). So nothing to worry about this controller

  Regarding the size of disk/RAID you mentioned, you may need to divide the RAID in several logical volumes using the ACU (Array Configuration Utility) as a result of a problem with the currently used driver (see http://kb.vmware.com/kb/2006942). I would recommend that you create a logical volume of 10 GB for ESXi and divide the disc space remaining in two logical volumes for use VMFS data warehouses.

  BTW. the controller has BBWC (battery backed write cache)? This is very important and makes a HUGE difference in the performance of the disk.

• Field number validation

  Hello
  
  How do number field let in only 6-number no more (< = 6, for example 1, 22, 23453, 123456, but not 1234567). What kind of valdiation I need to use.
  
  Thank you.

  Well you should say that: P

  You can make a return text Validation/PL SQL/function Page level and use something like this:

  DECLARE
    v_error VARCHAR2(4000);
  BEGIN
    FOR i IN 1 .. APEX_APPLICATION.G_F03.COUNT
    LOOP
      IF  LENGTH(:APEX_APPLICATION.G_F05(i)) > 6 THEN
          v_error                           := v_error ||
          'The row with the X '||:APEX_APPLICATION.G_F05(i)||' is wrong
  ';
        END IF;
      END LOOP;
      RETURN v_error;
    END;
  

  Don't forget to reward me and other people in the future or past (since you have some issues Total: 47 (29 remaining)). My advice is to reward people on our subjects with useful and accurate points.

  Edit: Textfield or number it is not severe, you can try with the array of double. Select length ('abcdsadasdas') of double; Select length (12312312) double; It will always return the number of characters (length) of the string.

• read several off file lvm 2D arrays

  Hello

  for the acquisition of my data, I join three tables 1 d in a 2D array. I then record several of these paintings in a file of lvm 2D, until she is larger than 500 KB. Here, I got her 'write to measure' express VI. When I'm reading the data, I have a problem:

  "the measure file read" express vi, seems to give only the first 2D table, which is located in the file! Each 2D table contains 75 values for each channel. I checked the content by drag / drop the file in Excel and Notepad. I see then all the tables, I saved in the file and not just the first. I tried to adjust the parameters in the "read the measurement file" VI as well, but nothing seems to help.

  I have attached a sample file of lvm and my VI of reading.

  It would be nice if someone could help it

  Simon

  Hello

  I don't really know which way you want to read the data.

  Do the different 2D picture belong together, which means that table 2 is just a continuation of the first?
  If this is the case, you can select 'Segment Headers' > 'No headers' in VI 'Write to file measure. "

  Then, select "File as read": read generic text file and adjust settings accordingly.

  Use the function 'Now read file' to test the settings.

  In addition, you may need to modify the indexes for the table to Index in your VI.

  However, this method has the obvious drawback of losing the header information.

  Alternatively, you can save the data in a PDM file, instead of a file of lvm. Here the headers are treated better.

  Select 'Header only' in the writing to the file of the measurement. When your then read the data, it will automatically read all the data.
  And you keep at least the first header information.

  If each 2D table should be read separately, you must use a different approach. Please let me know, if this is the case and that I will explain later.

  Kind regards

• Adding items to an array of unknown size several times

  Hey,.

  I had an application that communicates with a device (a generator of microwave) via the Protocol modbus RS-232. It is within a state machine. The VI running generator initialization first and then move to the State 'pending', where I have a structure of the event to follow any value change of control. In the structure of the event, a timeout of 300 ms is implemented, because communication to the generator must be active at least every second (if not a defect is reported). In the case of timeout I read all record and display values.

  Within this time-out I would record a value of the indicator ('measure Pfwd') several times in a 1 d table (the table size is unknown!). However, I would like for the variable to record only when the indicator 'MW?' is 'TRUE '. And "MW?" goes from 'FALSE' to 'TRUE' every time, I would like to start writing on a table from the beginning.

  I tried several options, including the table to remodel, but I can't make it work. Or it works in a separate VI, but when I use it within the structure of the event and state machine, nothing works.

  If someone has an idea, it would be welcome...

  Thank you

  Concerning

  Create an another shift register which is initialized with an empty array of the correct data type and use the node Build table add data to it when you want that he added.

  In BT, the size of a table doesn't have to be declared in advance.
