• 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 of Fortran in Labview

  
  

  Try:

  • pre-allocate array in LabVIEW (use initialization Array)
  • Change A setting to "pointer of table data.

• missing parameters in labview

  Hello guys,.

  I have a big problem.

  I really need to generate a dll on my VI (named "control da cast.. ').
  When I try to build, it should return me some settings, but it is not the case.

  I downloaded a sample of OR when it is operating normally.

  I have attached to it.

  I don't know what is happening.

  It's really basic LabVIEW. The connector pane is in the upper right of the VI editing mode. You have never created a Subvi where you pass/get parameters from a main VI?

  Your code is not at all suitable for a dll in any case with this loop and stop button that should be visible. Take a part of basic tutorials before going any further. Why a dll anyway?

• 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.

  

  "Interesting."

• Def sequence (table grapes) with loops, clocked by the relatively long software.

  Hello and apologies in advance I am an infrequent user of LabVIEW.

  Running on a VI to control a peristaltic pump and valve used to control some for a biosensor nanogap Microfluidic devices. I have the pump and the valve works manually (i.e., I adjust the values on the fly) but I am now trying to allow the user to define a sequence of steps that are then executed one after the other.

  User input: number, flow, duration of valve, pump direction (boolean).  Ideally the user can then run several different steps by adding more steps, so I thought of an indexed cluster array where each element represents a step?

  I would like the user to enter the time in minutes and seconds. The minimum will usually be 30 seconds and could be as long as an hour. I'm not sure of the best strategy for the timed loop, if I understand the use of the block 'waiting (ms)' can cause problems. I thought about getting a timestamp, a value added to it and the comparison? Are there any other suggestions?

  Any advice would be appreciated.

  I use an acquisition of data USB-6009.

  PS the VI LabVIEW is probably an education version, so may cause problems when opening?

  Just ask yourself how you should architect your code? Using a table of parameters of the step is an eay easy to do. And the wait is not necessarily a bad thing, it depends on your application and if you need the calendar to be exact in a certain way. You can use wait it until Mrs several place for synchronization.

  You can lookin to a State Machine architecture to make the best UI feature.

  The Computer of State Simple model that comes with LabVIEW is really the best way for new developers to become familiar with LabVIEW using a semi scalable architecture.

  Here is a large example of the works of a state machine:

  • States: Init, slowed down, exit, DoThing1, DoThing2, DoThing3
  • Each State contains code that could take some time. Ideally, not too long because this is how long your code might not meet.
  • The idle state contains a structure of event for all of the user interactions.
  • The front panel has a button that says "do the 1 thing.
  1. Loop iteration 0: Application starts, the first State is Init. Init State made the initialization stuff and tells the application to go to the idle state when finished.
  2. Iteration of the loop 1: request goes to the idle state. He's sitting there, waiting for the structure of the event.
  3. Time passes, and then the user presses the button 'do 1 thing ". There is no code or minimal code, within the occurrence of the event. The output of this state of the event tells the application to go to the State of DoThing1.
  4. Iteration of the loop 3: Application passes to the State of DoThing1. Here, there is code that does a few things. The output of DoThing1 State tells the application to return to the idle state.
  5. Iteration of the loop 4: Application goes to a State of rest where he waits again to the structure of the event.
  • Each State can tell the application to go to any State they want. You want to reset? Return to the Init State. You want to put an end to the program? Go to the exit State. You want each State to start another (such as a sequence)? Have DoThing1 out of DoThing2, which DoThing3, which outputs Idle.

  You can create a report that runs the cluster setting input and operates it. The risk with a long wait, is that the code will not be able to receive entries to user during this waiting period. So if you make a long wait, you can use a VI of elapsed time to check several times if the wait is over.

• LabVIEW 8.6.1 - message builder vi is password protected

  I am new to Labview 8.6.1 and I get a few messages I can't explain why. Labview is the construction of an executable, I have a few messages such as the one displayed in attachment. The messages are associated with the screws that are part of the Labview library and are protected by Word. Usually I ignore messages. I wonder why I see these messages.

  Another question: you can see the entire hierarchy of the project to generate an executable from just in Report Designer by exploring the table of parameters VI in Labview 7.1.1. Is it possible to see a similar thing in Labview 8.6? Or Labview 8.6 builds any project no meter if I put the generator in a certain way, with only a few screws of the whole project?

  Hi Virginia,...

  have you checked the field to change/remove the password?

  The manufacturer includes only the vi of always included and all dependencies of this as well as all dynamically vi with also all dependencies.

• 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.

  I also read the following posts:

  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!

• Trainer of OCR OR in LabVIEW

  Hi friends,

  I am using the NI trainer OCR in LabVIEW module directly which is now accessible only in vision assistant. But it is not loadable, and I'm not able to open the VI it draws vision assistant OCR. Is there a way to call NI LabVIEW trainer OCR?

  Currently, the command line arguments, I mentioned is the only way to pass parameters between LabVIEW and OCR training executable.

  Once you're done in the training interface, if you have made changes, the software prompts you to save the character set the file at the specified location.

  In LabVIEW, you can use the OCR screws located in the Machine Vision > palette OCR open file character set and get all of the properties that have been defined in the training interface.

  Watch the screw IMAQ reading OCR Character Set file, IMAQ OCR property.

  Hope it makes sense.

• 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

  In the attachments, you can find the .vi file and the excel file to run the program...
