• How to test the stability of the communication and to calculate ber using the CVI?

  Our Chief Engineer gave me a task yesterday. He asked me to make testing of software and to calculate the error rate binary we would like to know our stability of communication.

  However, I never touched this aspect of knowledge. I know a bit about the CVI and I want to write code with CVI bit error rate. So I could test the stability of the communication.

  But I don't know how to analyze and judge the receivers codes, whether they are good or bad.

  We use the Modbus communication protocol and receive data via a port series, so I want to back up all the data and record the total number of datas, marking as M.

  then, save the eligible data and save the number marking as N. Thus, the error rate is binary/m (M - N).

  If it's doable? Or you have a good idea. Thank you very much.

  unsigned char in_data[100]; 
  
   inqlen = GetInQLen (comport);
   for(i=0;i
  Above is my code that receives all the data I want to save the data [] array in_data and save the number.
  switch(inqlen)
  {
   case 19:
   {
     crc=usMBCRC16(in_data,inqlen );
     if((in_data[1] == 0x03)&&(crc==0)&&(in_data[0]==device_addr))
      {
  
      }
   }
  
  Above is the judgment of condition who receive eligible data which mark as N number.
  I know there is a prerequisite that I filter all the bad data. However, I don't know any good idea. I'd appreciate if someone could help me.
  Thank you very much.
  Best regards.

• Run the CVI in Visual Studio code

  Hello world

  I tried to get a CVI code to run in Visual Studio using this guide (http://zone.ni.com/reference/en-XX/help/370051V-01/cvi/usermanual/prjbldmenuextcomplrspt/). So far I've managed. However, I was faced with a non-fatal errors. Apparently, Visual Studio is not following them. Also, fatal errors do not produce a meaningful error message. Is there a way to get these error messages from inside Visual Studio? Maybe there is that an event reminder/whichI can use.

  Thanks in advance.

  The feature you describe is called "user protection". In addition to reporting the pop-up windows error codes, it also warns you if you access an invalid memory, data types to pass to functions that expect different data types, detects local variables uninitialized, etc...

  Unfortunately, the protection of users only works for programs built in debug mode using the CVI compiler. If you generate your source code in Visual Studio, the compiler VC injects not the information necessary to protect the user from working.

  The only way you could get this works in Visual Studio would be if you could somehow isolate all your CVI code in some DLL that build you with CVI, then call this DLL from the rest of your program, what you have created with Visual Studio.

• In previous versions of the CVI, use OpenFile with no path intended to look into the local path (i.e. the installation directory). Is there a way to do this in 2013 CVI?

  I use an .ini file to allow users to change the preferneces for starting the program. In the past, this file has lived in the installation directory and OpenFile could find the file cheerfully and apply preferences. In CVI 2013, the program seems to need an implicit path to the file. Is there a way to get around this?

  I use not yet CVI2013, but in any case, you can build up to a full path of a file in the folder of the application using the GetProjectDir and MakePathname commands when running.

• How can I build a dll containing that a callback function, the callback function is used in CVI.

  Hello

  Case is that LABVIEW receive external data and produce an interrupt, then sends the data to the CVI.

  Can I generate a dll containing a callback function, use the callback function in CVI. Or there is a better way?

  Thank you

  
  

• CVI DLL using the reminders of Message Windows

  Background:

  I had a CVI wound around a third-party DLL executable application.  Recently, I've built a few LabView modules and wanted to use the features in the code of the CVI.  I deleted as much as I can from the code of the CVI and built a DLL out of it, so now that it's a call to a third party DLL DLL of CVI.  The third-party DLL uses windows messaging to communicate with the CVI DLL.  I wanted not to re - write the functions already developed in CVI in LabView (much too much effort).

  Problem:

  The problem is windows messaging in CVI uses the InstallWinMsgCallback and binds it to a group of experts.  The events are not processed until you call RunUserInterface(). RunUserInterface does not return. Therefore, any LabView module that loads this DLL crashes, waiting for the DLL back.

  Does anyone develop a CVI DLL, which uses internal reminders, which can be called from an external process?   Anyone have any ideas on how to get around?

  Daniel,

  In fact, I came across the solution even before that you posted.  One thing I noticed however was that it was a little unpredictable when the message would be received.  It turns out that defining the InstallWinMsgCallback to intercept that in_queue worked without needing a processsystem looping events.

• Reliablity of the use of the CVI DLLs in testStand

  Hello

  I wrote a file .dll using the ICB and tries to use the functions available in aid TestStand. I get strange errors, not always but when I run TestStand. Here is my code in the dll.

  int GetAverage (double* aBuffer, unsigned int aSize, double* aAverage)
  {
      double total = 0;
      enum t_eErrorCode eErrorCode = 0;
  
      if(aSize <= 0)
      {
          eErrorCode = eARRAY_SIZE_ZERO;
          goto Error;
      }
      for(int i = 0; i < aSize; i++)
          total += aBuffer[i];
      *aAverage = total / (aSize);
  Error:
      return eErrorCode;
  
  }
  

  He sometimes throws only an eError_SIZE_ZERO error, but when I checked in the debugger TestStand, size sent to the function was not a nullity (see attachment).

  What can be the reason or what I am doing wrong?

  Thanks in advance,

• How to use the resistor Programmable 2720

  Hello

  I'm using and programming with the PXI-2720. Could I put the value of the resistance to the CVI program?

  I put the niswitch.fp in my project.

  I do check all relays for making 30 ohms (example value) in my program?

  Could you help me if you have code samples or references?

  I used '272 x screws of reference' for LabView.

  I'm looking for a similar instrument to the ICB driver.

  Thank you

• PC (Win7 64 bit) freezes completely after some time due to the CVI 9.0.1 32-bit application: question in cvirte.dll

  I have a strange problem with my app CVI. After a while, no constant time (especially on a day or two), the PC freezes completely when running my application. Examine the system event logs, I see a lot of entries from the CVI, sometimes 8fois per second!

  Above all, it looks like the following:

  The description for event ID 0 in source CVI could not be found. Either the component that triggers this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

  If the event is on another computer, the display information had to be saved with the event.

  The following information has been included in the event:

  [14:18:42.389] [GetLWMessage] [FATAL] [.. \jsource\jn_msgs.c:672 assertion failure]: WRONG (error in the message handler: code #12689 unknown message received)

  Although the system event log is set to a size of 20 MB only and the fact that it is automatically overwrite (FIFO) itself, the PC won't be able to do in the face of this large amount of entries in line waiting.

  I searched the internet but found absolutely no clue. I searched then through my code using find in files and finally only found the following within the cvirte.dll sequence when you use "*." "*" as file extension filter:

  .. \jsource\jn_msgs.c ConvertMsgText error in the message Manager: unknown message code #% ld received GetLWMessage

  Why exactly what the system event log tells me. I wonder that there are some things Java in a related CVI runtime dll

  Know someone, any idea how I can fix this problem?

  I tried to run my application using WinXP SP3 compatibility mode, but this did not help.

  I'll try to refine the question. I will also try to recompile my application using CVI2015

  The application does not generally crushed. There are different configurations of my tool where he works a lot of days. So, I have to determine the exact circumstances. Also there is no memory leak, so does not unnecessarily increase consumption of RAM during execution.

  Any help much appreciated

  Thanks and greetings

  Hi Kyle,.

  Thanks for your response!

  In the meantime, I managed to solve the problem. Checked the date and version of the DLL runtime on the target PC, I found that they differ runtime DLLS that have been installed with my application using the distribution kit. After the reinstallation of the application, there was more no new error event log entries, so this solves the problem :-)

  Only, I wonder where these DLLs from...

  Thanks and greetings

• Use the return value to do step digital multiple success or failure

  Hello

  I use a multiple digital step to check several measurements by an external DMM through a function created in CVI.  I would like to use the return value of the function to replace the global status of the step. The reason is that the return value indicates a communication error, while steps are being taken, and which would lead to a "fake" fake or false 'Pass '.

  What I would do is more or less this >

  If the return value is 0, then check if the measuremets are between the limits

  If return value! 0 = there was a communication error so step continues to operate independently of the measure.

  I tried combining multiple digital step with a step of pass/fail, but it does not work.

  I also trie to change the expression of the status of the multiple digital steps but basically ignores him.

  Any ideas?

  Thank you

  Javier

  Why don't you just make that return the value limits for multiple numerical limit stage.  Comparison of the EQ value and the low limit to 0.

  That would make the most sense.

• Not able to use the Handle returned by open with LockFileEx

  Hello

  I try to use the file returned by open handle to lock the file using the Windows SDK LockFileEx function. It gives me an error like invalid handler. PL suggest me the solution.

  Kind regards

  You use a SDK function to open the file? The ANSI fopen() function handle or CVI OpenFile() functions won't work - you need to handle SDK function.

• Get the array of unknown size of the CVI code module

  I'm creating a type custom for my client, and I've encountered a problem that I'm not sure how to solve.

  Here's the situation:

  We have a custom step in which the main code is executed within a step after step. The code acquires samples of an instrument, but it is unclear how many samples will be returned. The CVI function has a table, the size of this table and an output parameter that indicates how many samples have been returned as parameters.

  void AcquireSamples (double* samples, int samplesBufferSize, int *numSamplesRetrieved)
  

  The goal is to have the array returned by the size of the number of samples taken.

  I tried several ways, none of which works completely. The problem is that, as described here, TestStand creates a temporary table to move to the code module. but it does not resize the TestStand array property. So I need to manually resize the properties of the table, and I did not understand an elegant way to do it.

  It would be easy if I had to create just a not, because I could use expressions after. I'm creating a type but I don't have that luxury (my code should allow the customer to enter expressions of post, but I run the risk of my client, removing any expression after default I get home).

  First question:

  I noticed when I was creating a stage with a CVI code module, that additional results allowed me to specify logging in both settings [in] and [out]. This I extrapolated that the parameter expression was evaluated before calling the function both again after the call to the function. I did some tests, and it doesn't seem to work that way.

  (1) this is expected behavior? I don't see it documented anywhere, if can I rely on it remains the same in future versions of TestStand?

  I used this behavior to my advantage to create an expression that does what I need an an step code module. But it does not work for a module of code to a later stage.

  I did a small test DLL file and sequence illustrates my problem. I tried to document the file in sequence to show where I'm stuck. You will need to put the DLL in one of your directories to search for the type of custom work.

  Any help would be greatly appreciated!

  I think the problem is that the C programming language does not provide enough information for a caller to know the size of an output table in any kind of standard. I recommend again, you pass a CAObjHandle which is the variable of array instead and set the table directly using CA_Array1DToSafeArray() to create a safearray and SetValVariant on the propertyobject which is the property of the table to set the table. Don't forget to free the array (using CA_SafeArrayDestroy()) that you created with CA_Array1DToSafeArray after that SetValVariant call to avoid leaks.

  Hope this helps,

• Is it possible to use the power line is in PlotText?

  Hello

  I was wondering if I could print two lines just below the other on a chart using PlotText control and a jump in the line text string? Unfortunately, I could not do it using "bla\r blah" or "line1\n line2 '... Is there such a possibility?

  Thank you

  Wolfgang

  Hi Wolfgang,.

  Unfortunately, the current PlotText function does not support the escape characters. This is a known issue and should be resolved with the next major version of the CVI. I'm sorry, that there is no better solution for now.

  Best regards
