• use IMAQdx functions in Labview Communications System Design Suite

  Hello

  I would like to read an image and use the bytes obtained to perform certain functions. Currently, the system has Labview Communications System Design Suite (2014 SP1)

  and vision acquisition software installed. I don't know how to use IMAQdx features in labview.  Can anyone help?

  Thank you!

  I do not work with the Design Suite of Labview Communications System.

  In LAbVIEW, however, when after you install LabVIEW first, then the Vision Acquisition, you can use the example Finder locate IMAQ or IMAQdx for LabVIEW examples: in LabVIEW, select help > find examples. This will open the Finder of the example. On the "Search" page, type the keyword "IMAQ" or "IMAQdx" (depending on your device) and look at the examples that come with the Acquisition of the Vision for LabVIEW.

• Deal with failure when using LabVIEW 2011 and DSC MODBUS communication

  I'm currently reading from operating records a PLC with MODBUS/TCP. I confirmed that the PLC will update the values and in response to a MODBUS communication correctly by using a third-party program called Modbus Poll. However, when I try to query the PLC using the LabVIEW shared variable engine, I am unable to read the values of the same addresses that I consult with Modbus Poll.

  My installation is simply to a PC directly connected to the controller via Ethernet without a router between the two. I'm using LabVIEW 2011 SP1 with the DSC module.

  I opened the Manager of distributed systems OR to display the State of all variables in the Modbus Library that I created, and I noticed that the ILO CommFail permanently the value 'true '. All other variables with a 'read' access mode signal "failure of process". I tried to restart the process and stop and start the local variable engine without success. I also restarted my computer several times to see if any services did not exist, but this does not appear to have solved the problem.

  Finally, I resorted to listening to communications on the network card I have the PLC connected via Ethernet using Wireshark and found that while Modbus Poll communicates with PLC, number of MODBUS and TCP packet is sent and received. However, when using only LabVIEW or the DSM OR communicate with the controller, there don't seem to be any communication on the network card.

  Something that may be interesting to note is that I could communicate with the PLC and to read values with the DSM just once, when I understood everything first what address I should be reading of. All of this has stopped working shortly after. Prior to this, 'CommFail' was not generally set to 'true' with my current setup. Thinking it was my firewall, I have since disabled my firewall, but this seems to have had no effect on the problem either.

  Any help on this would be appreciated.

  So, I thought about it. It turns out that the IP address of the server i/o MODBUS must be set to the address of the MODBUS slave, not the local computer. The address of the i/o MODBUS server is defined by the navigation in the Explorer window projects, expanding the variable engine shared library for MODBUS and right click on the server MODBUS (for example Modbus1) item and select Properties.

  In addition, the addresses seem to be shifted by + 1.

  Thanks for the tip so.

• How to transfer files from PC to PC via a serial port using labview

  I need to transfer files (.txt, .doc, .xls) from PC to PC via a serial port using LabVIEW. Is it possible to transfer files, if so how to transfer?

  Yes, it is possible to transfer files with the serial port using LabVIEW.  The files are just collections of bytes and the serial port is good enough in the expedition of the bytes from one PC to another.  You must connect the ports series with a null modem cable.

  First, take a look at the example of serial communication.   In LabVIEW, go to the Help menu and select «Find examples...» ».  From there, you can search for "serial" or navigate to hardware input and output > series.  Select «Write series base» and Read.vi  Try this example to gain confidence on the serial communication methods.

  Then it's time to learn how to read and write files.  For this, the examples might be somewhat confusing as they deal with files that are presumed to have data of a specific type in them.  I would recommend just familiarize yourself with the functions in the file e/s palette.  Specifically, familiarize yourself with the following functions.

  1. Open/create/replace file - on the side of your destination, you will need to create the copy of the file you are trying to transfer
  2. Close the file - when you're done reading or writing to a file, you must close it.  It cleans the memory used and finalizes write operations that are still floating in the write buffer.
  3. Read a binary file - is the best way to play a file when you don't really like what type of file it.  In your case, you just want to get these read bytes and sent so they can be written down instead of destination.
  4. Write to a binary file - next to the destination, is what will store the bytes in the file that you created with the number 1.
  5. Size of the file get (under the range of the advanced features of file) - you need to know how big the file is, so you know when you are finished.

  OK, so once you are able to create files byte write and read bytes from existing files, you can move forward.

  I suggest the basic method is to have the user specify a source file on the source PC, and a folder on the destination computer.  Then find the size of the source file using the number 5.  Divide this number of size by the number of bytes that you want to transfer to the times.  The series pads are usually around 32 k (if I remember correctly) in order not to exceed that.  Now start to send data by reading a number of bytes and this string output wiring to the feature of writing VISAS.  On the side of destination, you will want to monitor the serial port for bytes and read when they arrive.  This string of yarn to the writing of the function of binary file to add them to your destination file.

  This is the basic outline of how to do it.  He needs to not to overload him write and read buffers on the serial ports.  Initially, you can use delays on the side sending to make sure that the side reading has enough time to digest.  To make things faster, you can bring in a control of flow.

  If all that sounds a little intimidating, there are there Alliance member companies (such as the automation of PrimeTest) who can write this code for you and even provides a turnkey for you solution.

• LabVIEW Communications System Design Suite with 10 64-bit Windows

  I would like to know is possible to run LabVIEW Communications System Design Suite on Windows 64-bit 10. According to the Web site of NOR, he says that he only supports 64-bit Windows 7. So is it possible to run it on Windows 64-bit 10.

  Please guide.

  Thanks in advance.

  Hi josephkirmani,

  Currently LabVIEW Communications System Design Suite is not supported on Windows 10-64 bit. You may be able to make it work on your machine, but unfortunately it is not officially supported outside of Windows 7-64 bit.

• How can I display the time of the data stored in a file using labview?

  How can I display the time of the data stored in a file using labview?

  Hi Matt,

  I think that we will need a little more information as to how you capture the data, what data you capture, etc.

  If you capture a waveform, is to extract the time data waveform which includes the t0 and dt values, so you can understand the time stamp of a specific data point as in the image below.

• Transfer TDMS file cRIO 9076 PC locally using Labview code problem

  Dear all

  I use LabVIEW 2013 with cRIO 9076 for datalogging PDM.

  I try to transfer the logging queue (.tdms) cRIO to the computer via the LabVIEW FTP software. The transfer is OK but computer I can't open the file-68007 error.

  It's ok when I copy the cRIO on computer file ( ftp://192.168.2.102 and manually copy the file)

  Dennis has already said: for a direct PC - PC connection, you need a cross over cable. If you connect through a router or a switch, you use a standard cable.

• build a Visual Studio C++ 2008 .dll file and use it in labview

  Hello

  A few days I tried to create a .dll with c code file and use it with a call library function node in LabView. But I could never do it with success. I use Visual Studio 2008 and labview 8.6.

  I had a look at some tutorials, but they were written for different versions of Visual Studio. And because I'm a newbie to Visual Studio, it was difficult for me to do in another version the turtrial is written for.  However, I have a lot of experience in programming c for processor atmel (AVR Studio).

  Is there someone who could help me step by step hollow Visual Studio C++ 2008 and later versions also help me configure my call library function node?

  I'm form Switzerland, my English may have a few errors. Sorry for that.

  What I've done so far:

  * I opened VisualStudio 2008 and created a new project.

  * For this I used the model ' class library ' (because I live in Switzerland, I have German versions of visual studio, and labview. So, probably, it is not called exactly "class library" in the English version)

  * The project is created and I can insert my functions.

  * but here I have some difficulties: in my tutorials, they say that a function should be defined as follows:

  type name (arguments) WINAPI

  {

  code

  }

  for example

  unsigned int WINAPI multiply (unsigned char, unsigned char b).

  {

  unsigned int c;

  c = a * b;

  return c;

  }

  but when I try to compile the project I get the errormessage:

  SyntaxError: missing; prior to "multiply".

  * When I remove WINAPI, it creates the dll file

  * but when I try to open this dll with a "call library function node" in labview, I get an errormessage labview, that my multiply function is not found in the dll.

  I'd be happy if someone could help me with this.

  You need adorn your statements with extern "C". LabVIEW manages only the C dll; It cannot manage the C++ dll, which is what you will get if you do not have extern "C". I do not understand why you are trying to use 'stdcall '. For a normal DLL just stick to C-calls.

  The link provided by Red rooster is for Visual C++ 6, which is a very old version. I suggest you look at instead, because it deals with Visual Studio 2005.

• Call a visual basic executable file with arguments command line using LABView

  Hi all

  I try to call a visual basic executable file with a command line using LABView 2014 argument. What I'm trying to accomplish executes an executable file that communicates with a device via a COM port. So, I would open the .exe with a command line argument to communicate via com 3 using the SYSTEM Exec VI. It seems that the command prompt window flashes and closes and then nothing happens. Not a lot of discussions about this on the forum. Any help would be greatly appreciated. Thank you.

  With some programs, instead of passing in the string:

  Somefile.exe

  Instead, you can use:

  cmd /c "C:\Full Path\to the EXE\Somefile.exe"

  Can you tell us what exactly you are trying to run?

• Using LabVIEW LabView not having files not system

  Hello guys,.

  I'm using Labview 8.5 and I designed a particular VI... Now, with the help of tutorials on Developer Zone, I have prepared an EXE file in the same way it works on a system that isn't Labview... (Point of view of users.)

  but I found my .exe file does not... Error message... Install the runtime Engine 8.5... I installed the same... and even today... double click on the right icon does not display anything... even not an error mesg... can someone tell me a solution for the same...

  At the same time my VI use mx data acquisition (DAQ mx 8.6) and I have a slight confusion if these tasks can run on a system that have labview and therefore not your tasks... I have to switch to something that creates tasks first, and then executes the VI... Something of this sort is possible in Labview 8.5... help plz...

  When you create the installation program, select this option to export the MAX configuration so that will be included in your Setup and also include DAQmx and MAX as part of Setup.
