• 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.

  Happy wiring,

• Possible to use labview with daq system not of NOR?

  Hello

  I have a daq system and the software from another company that NEITHER. But I want some changes in the software. If the opportunity was to make a new program with Labview.

  Is it possible to use the old system of data acquisition? Is this compatible with Labview? Or I have to buy new hardware?

  Thank you.

  Hi VIassaks,

  Good afternoon and I hope that your well today.

  Thanks for the post.

  LabVIEW can communicate with 3rd party hardware using the library function call is located in the tip under the functions Palette palette. If your equipment is equipped with a DLL at the driver level LabVIEW can communicate with the hardware. However, you must obtain documentation of the DLL so that you can create your own interface for the material of the part 3.

  Another option would be if the hardware manufacturer provided LabVIEW VIs that control their material. You will not be able to use the screws (National Instruments Data Acquisition DAQ) because these screws use the DLL OR-DAQ, which is our software at the level of the driver for our DAQ cards. Other companies use their own software to the driver level to control their own material. Only the National Instruments hardware uses the NOR-DAQ driver that allows you to use LabVIEW DAQ screws.

  Hope this helps,

• Missing link in the file write Key.vi LabView after switching LV development system server to RTE

  Hello

  TS4.2 LV8.6.1

  I have a strange behavior of TS. All of the code works well under the development system. But when I pass the server of LabView runtime LabVIEW development system then, during the call one of my screws (action step calling the LV adapter), I have the window 'vi search' open looking for the Key.vi to write (one of the interns LV VI). Finally, is the write file Key.vi and TS is happy, however, I don't want it to happen on the production floor.

  Is this a bug or I have some sort of option or something?

  Why this does not happen under the development environment? What is the mechanism?

  K.

  (1) more complex nodes in LabVIEW are stored in vi.lib.  This is not uncommon.  Are not only very basic items (add, subtract, table functions, etc...).  They are usually yellow and you can not open them.

  (2) they need to go somewhere, and vi.lib is the standard location for all built-in screws

  (3) instr.lib is very similar to vi.lib, just a different location.  LabVIEW stores a relative path for the screws here called in.  This path does not exist with the runtime, although TestStand will add it in the search directories if you installed LabVIEW Development.

  (4) if it is possible to use LabVIEW to do this, there are more ways to get into trouble, because doing it this way would never update your sequence or find problems that would be specific to TestStand.  Is there a reason why you don't want to use the TestStand deployment utility?  Behind the scenes, TestStand calls in the same frame as LabVIEW for the deployment, but do it with more knowledge that LabVIEW alone would have.  This can be done, but there are more considerations, and you can meet potential problems.  Unless you have a good reason for this, it is generally not advisable.

  I recommend reading the chapter on deployment in the handbook here (Chapter 14):

• 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 an FPGA as a stand-alone system to run labview 2012

  Hello

• Delete or not; "System error Memory Dump Files" & "Debug dump files" in the Windows 7 disk cleanup program

  I am new to Windows 7, 64-bit OS and making the disk cleanup program. There are 2 unfamiliar topics with boxes to check what are the "Debug Dump Files" and "system error memory dump files.  I'm naïve as to what are these files and whether they contain all files that possibly should not be deleted.  Can anyone say and find out about what are the debug files and system error Memory Dump and if; Should I or not the check their boxes to get rid of all these files in particular type box?  Or could there be some Debug files & system error Memory Dump that might be of some importance and should not be deleted?

  Thank you for your time and any comments on this would be greatly appreciated.  Have a nice weekend.

  Tom R

  One good thing about Windows Disk Clean up is, only offer files delete them it is safe and will not harm your PC. Files of system errors and debugging dump files are created when there is an error in your system, and it creates a dump file that could be used for analyses. That say if you encounter blue screen error, dump file will create and if you find analysis you of cause of this problem. Whether or not you want to remove, you, some people will delete it only while others will keep the Explorer themselves later. But more importantly, it is wise to report them to Microsoft before deleting.

  To do this, open Control Panel and click under Maintenance contract and Action Center, click Check for solutions then it will collect all the information related to the errors and dump files and he could ask permission to send them and if you great permission, they will be sent. Once it was successful you can delete them.

  Sending the Microsoft dump files is a good idea, because there are teams who revisit and they try to find the cause and resolve it through Windows Update, or inform you about the possible solution in the center of the Action.

  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.
