• Table of parameters of labview

  Hello

  I want to join UInt8 tables (MSB/LSB) to an array of UInt16.

  

  If I run that in LabView is not a problem.

  But when I call to TestStand, there is no full Out parameter.

  

  After I run the Teststep there are no values in the Locals.MSBLSB table. Is there any parameter, I had to put this LabView can write in the Locals.MSBLSB table?

  Respect,

  René

  So what values you have in the two tables locals.lsb and locals.msb because if these are empty tables so you will not get any output?

• How to write the table 1 d of labview to Excel line wise?

  Hello, I'm cooler in labview and want to learn it thanks to you all and of course myself.

  I 1-d arrays of strings and I want to save in excel file one by one and line by line. designates a 1 d in a line chart, the next time, a neighbor on the next row and so on.

  but I find I can do with only 2 - d Mr. table or table is stored in a column. Please help me. while I can do more. I have the trial version.

  Hi janki,.

  do you want a real Excel file or file that can be opened by Excel? You have to write this rank by rank or is it also OK to write all your data to those? Perhaps, 'Write in a spreadsheet file' function is enough for you.

• Table axis range error labview

  Hello

  I'm trying to programmatically set the chart to display a minute 30 or 60 minute range. I can do this by setting the following in a case manager properties, if the user presses a button to apply the settings of the map (with the display of absolute time format):

  Entry: graph time = 30 minutes or 60 minutes

  Properties (in order):

  Scalefit value of 0 (no autoscale)

  Offset of the value timestamp 'get the current time.

  Startrange value timestamp 'get the current time.

  Multiplier to 1 /(1000 Samples)

  Minimum for the timestamp 'get the current time.

  Maximum to 'Get the current time' + 1800s (for table duration = 30)

  Loosefit set to true

  Result:

  While I can get the output offset table correctly, the time slot is always set to 40 minutes.

  I ask these same settings in the table more away in the loop and the min, max values are completely different - one offset is consistent.

  Here is a sample run: table length = 60,.

  Minimum = 15:01 25 January 2013

  Maximum = 16:01, 25 January 2013

  Offset = Minimum

  Output:

  Minimum = 15:02 January 25, 2013

  Maximum = 15:42 25 January 2013

  Offset = 15:01 25 January 2013

  I am confused because I have not set these properties of chart in my code otherwise. No idea where they come from? One solution is to take the code in the case manager, but I would like to refrain to do so because it uses more memory. Thank you!

  Could you post an excerpt of our VI?  It would be very useful.

  Right on the top of my head, I think you may have a problem with the amount of data in the table and affecting the size.  You may also need to set the length of the history of the chart.

  You might be better off using a graph of waveform instead of graph.  It is much easier to control the data in a chart as you define explicitly all the data instead of letting the LV to annex all automatically.

• Record in labview table data will not proceed to the next line

  Hello

  I managed to read data from Visa read and display a chart. Now, I need to put it in the excel file, but the problem is, it's still on the first line in excel as a table I generated in labview. I hope someone can help. Thanks in advance!

  Go to table 1 d and connect directly to the entry of table 1 d of scripture to the worksheet. Then, instead of this insertion in table, use a shift register with a table to build your table 1 d in low entrance and the wired output to the table.

• Table of waveform LabVIEW 2009

  I have a problem with the table of waveform in LabVIEW 2009, the chart will not poster on the table after a few iterations. This is a bug that appeared in LabVIEW 2009. The same program worked well with LV 8.6. Does anyone know a work around for this problem? I am currently using Version 9.0f2

  See the attached diagram

  It's strange...

  I checked that save this return to 8.6 does indeed.

  If you replace the function Merge signals with a bundle of things function seem to work fine.

  There is also something weird happens with the property node. If you start with a pnode for active track, then drag it down to add another element, then change this new element to draw colors, you get an error on the property node.

• How does the library function call Labview? Can I emulate using C++?

  Hi all. I recently finished writing a dll CUDA for LabView, and now I'm in the steps of optimization of code, memory management, etc. BUT since my code depends on the entries of Labview (lots of data under types of specific data as table manages and Clusters labview) I can't use the CUDA Profiler or the Profiler VC ++ on the DLL. What I intend to do runs labview and then out of all data entry for the DLL in a binary file and then add an additional function in my code that will read in the binary file, allocate and assign variables to their respective positions, and then call the specific DLL function in Labview. In the end, this miniature function will act as the library function call to my specific group of data entries.

  In any case, I started to make this purchase all my data entry of cluster and it comes out in a binary file. And then I started the initialization of the handles of labview, allocating memory and begins to write the binary data in the memory and it works for integers (ints), floats, etc., but I'm confused on how it works with table handles!

  Some examples of code:

  Sets the Handle for table 1 d for INT
  
  typedef struct {}
  
  	int length;
  
  	int val [1];
  
  		to access the value in a row-online val [Online]
  
  } Array1dInt, * Array1dIntHandle;
  
  int main()
  
  {
  
  	Array1dIntHandle x = new Array1dInt *;
  
  	(* x) = new Array1dInt;
  ifstream file ('TESTDATAIN.dat', ios: in | ios::binary);
  If (file.is_open ())
  
  	{
  
  		file ((char *) &(*x)-> length, sizeof;)
  
  		file ((char *) &(*x)-> val [0], sizeof (int) *(*x)-> length);
  LabviewSpecificFunction (x);
  
  		leader. Close();
  
  	} else
  
  	{
  
  		< "file="" did="" not="" open!"=""><>
  
  	}
  
  	return 0;
  
  }
  __declspec(dllexport) LabviewSpecificFunction (Array1dIntHandle x)
  
  {
  
  ...
  
  }

  However, my program crashes when the table is nominally big, and it is expected, because if we look at the Array1dHandle, it has allocated only enough memory to 1 item of value! YET, somehow, in its magical and mysterious labview is capable of making val [1] be val [HOWEVERMANYYOUWANT], even if C++ 101 says that val [1] is a constant pointer, and even if I dynamically allocated memory another somwhere, I would never be able to put these data in this round!

  Can you explain, or maybe even write example on how I can fool my program into thinking that the binary code comes from labview, so I can then run my program independent of allowing me to profile the functions inside labview?

  I hope that this question is clear and my sample code is also clear, but I'm happy to answer any questions that relate to this.

  Thank you all!

  I think that I thought about it.

  Array1dIntHandle x = new Array1dInt *;
  int tempsize;
  
  file ((char *) & tempsize, sizeof;)
  
  (* x) = (Array1dInt *) malloc (sizeof (int) + sizeof (int) * tempsize);
  
  (* x)-> length = tempsize;
  
  file ((char *) &(*x)-> val [0], sizeof (int) *(*x)-> length);

  Well enough, you will need to make the handle, and then make a new Array1dInt * for him, then read in the length of the array in a temporary variable. Then use this information to then malloc memoery quantity you need for the table and pass this place on the handle. Now the handle will point to the size of the memory and you will be able to access the memory in the format, you've done the handle. Badabing badaboom

• Table update permanently

  Hello

  Is it possible that you can be constantly updated a table or chart in labview without going through the instrument inside the loop of processing of the information itself? Basically, I want to take 10 readings of voltage and updated after each iteration of the loop at the chart. The problem I have is that I need the table outside the loop because it is connected to other data as well.

  Thank you

• Ridge table waveform detector

  Hi all

  I have problems trying to work with the Ridge detector tool... I have a file which contains 17 columns, that the first's time and the rest are data... I split and now Im trying to find the vertices of the first wave... I'm looking around and I find that it is only something bound on how the Ridge detector to receive data. IM now trying to convert the files again in a table, but only inside labview and I think that will solve this problem... but I can't.

  Please if someone could help me I will be really great

• How to transfer data from a DLL Delphi pascal class to a LabView data cluster?

  Hi all

  I have the following problem:

  I use a dll written in Delphi Pascal to transfer data to LabView by using the "Call library function node".

  My Delphi dll contains this class:

  TFlash = class
  Fi: TFileInfo;
  constructor Create;
  procedure LoadFi (Filedir_and_nametring);
  end;

  TFileInfo = record
  IDX:smallint;
  IdxLstSpl:array [0.4] of longint;
  Ms: Word;
  [0.4] SP:array of the word;
  end;

  I created the record datastructure of TFileInfo in a cluster of LabView to have the 'same' variable.

  My plan was to call a DLL Deplhi function with the "call library function node" and pass the address of the folder TFileInfo, so the data would be transmitted to the cluster of LabView.

  When I do a simple delphi dll function as this works because I only spend a small integer to Labview (without reference to the data structure):

  ...

  var data: TFlash;

  ...

  function GetNrOfRows(FilePath:_string):integer; STDCALL;
  Start
  Data: = tflash. Create;
  Data.LoadFi (FilePath); This function returns the number of lines in the selected file.
  Result: = Data.Fi.Idx;
  end;

  When I try to use this procedure instead of the above function, in order to pass the address of the data set structure complex 'Data' (TFileInfo), I am unable to get the information of 'Data' in my Labview cluster:

  procedure LoadFileInfo (FilePath: string;) DataPointer: Pointer); STDCALL;
  Start
  Data: = tflash. Create;
  Data.LoadFi (FilePath);
  DataPointer:=@Data;
  end;

  Parameters of call library function node:

  -stdcall (WINAPI)

  -Run in the UI Thread

  -Function prototype: void LoadFileInfo (PStr FilePath, void * DataPointer);

  * DataPointer--> Type: "adapt the type" and the format of the data: "pointers to the sleeves.

  * FilePath--> Type: 'string', format of the string: "pascal string pointer.

  I'm struggeling with this problem for almost a week now and I can't really find a solution on the forum or google.

  A little further:

  Seems like it's not possible to pass data from Delphi to Labview through a DLL when I create a cluster with 2 bays in it in Labview.

  This part of Delphi, I've had to make in Labview:

  TFileInfo = record
  IDX:smallint; {integer; Convert tool}
  IdxLstSpl:array [0.4] of longint;
  Ms: Word;
  [0.4] SP:array of the word;
  end;

  Instead of using 1 cluster with all the different data in it, I did a unit (1) with my 2 items (smallint and word).

  To pass my data in my tables from delphi to labview, I created another group (2) in the unit (1) with 5 elements of longint (because my delphi is going to 0.4) and another group (3) in the unit (1) with 5 Word elements.

  Right-click on the unit (1) and the clusterorder in the right order. First the smallint, then the longint table, then the word and the Word table.

  When I then use this code in my dll Delphi, IT WORKS! :

  procedure LoadFileInfo (FilePath: string;) DataPointer: PtrTFileInfo); STDCALL;
  Start
  Data: = tflash. Create;
  Data.LoadFi (Copy (FilePath, 2, length (FilePath)-1));         --> I need to cut the first part of the pascal string because it's length, and I only need the string itself
  DataPointer ^: = Data .fi;       --> pass the record structure to the cluster of Labview
  end;

  Thanks for the info Ralf!

• Can you attribute programmatically size when you use the table in the Cluster service cluster

  I use the table of the Cluster service.  The only way I know to the size of the cluster is to right click on the function and set the Cluster size.  But what happens if the length of my table changes?  Is there a way to make the cluster size is the number of elements in the table?  Seems like labview should do this automatically at run time.  There may be some nodes of property I don't know.

  I tried the SQL statements, but it always boils down to having to know the number of columns is in the database prior to execution.

  What I did to generate the object to be a cluster to match database fields.  My recordset is an array of objects.  Then I a vi member to build a recordset from the database and another Member vi to retrieve an array of clusters of the recordset object.  If the database changes, I have to change the subject and these two vi.  All the other Subvi call these two for the manipulation of data.  No other sub - VI have bundle and ungroup functions in them, only the vi of two members.  Thus a change in the database requires a change of control and two vi.  Not too bad.

  (I'm tooting my Horn in choosing me as accetped solution provider.  I learned this bad habit of others here on the forum.  )

• Container for several tables of different length

  Hey,.

  I'm doing an algorithm for labelling component connected in LabVIEW.  I came across the problem that I need some sort of data structure that I can't create.  I hope that I've missed something and someone can report this to me.

  What I'm looking for is a container that can contain lists of lists of 2 values.  Basically, I have several labels.  Each label will have a list of coordinates in.  The closest I came to this creation is a 2D cluster table.  Then, the cluster contains the coordinates X and Y.  The problem is that each list is not the same size, and for a table of 2D in labVIEW, all rows/columns must have the same length.

  In summary, I'm looking for a way to store multiple lists of coordinates.  The lists will all be of different lengths, and I don't know how many lists there will be.

  Is it possible to do this?

  If not, does anyone know an easier way than that looking for a 2D for concentrations table all?  At the back of my mind, I want to say that there may be a Vision VI of OR who can do this, but I can't find a.

  Thanks for your help,

  Dominic Walker

  A way to manage several arrays of different lengths (but all the same type of data) is to put the berries in a queue.  Each element in the queue must be a table, but they can be of different lengths.  To get to all the tables, you use the preview queue feature.  It returns an array of clusters with each table queue in a separate group (if I remember correctly).   Perhaps an array of clusters of berries would work for you.  I just checked that this allows arrays of different lengths.  You can also place a control of the chain with the label of the cluster if it is appropriate.
