series asynchronous message read

Hello world.

I have the message function device. I don't know when the device will send the message, so I didn't know how can we establish the VISA playback function to read range of the device (because it only reads data, which are activated to the serial port buffer). Maybe it can be made using VISA bytes to the port in while loop, but I'm not exactly sure how. Can you explain it to me? Or do you have another solution? Thank you for your help.

Hello

I reworked the basic reading and writing example series, just to give you an indication of programming. Also remember that then reading series buffer, you do not need to read all the content. Read the number of bytes that you need. The buffer of the series is FIFO. If the older content will always be first in the queue to read.

My example is a bit simple, and I didn't test it but should work. Discover the queues and the authors of the notifications (in the finder in the example) to advanced programming techniques.

  • Can't write series base and Read.vi to run

    Hello

    It is a strange problem because I used this .vi including several times before and never had a problem until I have created LabVIEW on my new laptop computer. I installed everything like I should without a problem, but for some reason when I try to run, I get the message:

  • Tips for the TCP wait of asynchronous Messages with non-standard expression tanks

    Hi all

    I have a PITA instrument that I need to communicate with in a system of greater control.  This instrument communicates via RS232 to a server running on the PC OEM application.  In order to communicate with the instrument, I have to use the TCP protocol on a specific port on Localhost - So far so good as long the protcol is answer command.

    The problem is that the instrument sends several messages asynchronously of different sizes with a double newline as a tank of termination (there are many CR/LFS all these messages so that they cannot be a MOE) and I am struggling to find a way to manage receive asynchronous messages of variable length with a cusom CHARACTER term. without having simply a fast dedicated for TCP loop reads trying to catch these asynchronous status messages.

    I wish the functions VISA TCP has worked with the local host, given that the properties that can be set to change the chariot of non-standard term.

    Open to suggestions-

    Thank you

    Yes, I'll be streaming in my own string buffer and then to choose the messages out of the buffer when you find the stop character.

    A technique to improve performance, rather than reading a single byte at a time is to use the "immediate" on reading TCP mode and use a high value for the "bytes read" - in this way, it will return all of the data that is there without waiting for all the specified bytes or the time-out. He will wait only the full timeout if 0 bytes are received (which you can ignore) - set to a low value such as 100ms.

  • LiCor series - hex 0xBFFF006c read errors

    Hi all

    I tried these last days develop a series VI to read the data of a 820-LiCor-CO2 gas Analyzer. I know what is sent to the device to a request to send data to the computer and how to analyze these data once it gets in return. Its manual settings are Baud: 9600, data Bits: 8, parity: None, of Stop Bits: 1 and flow control: No.  I had problems with the hexagon-0xBFF006C "a time-out error occurred during the transfer. A character not read in the material before the next character arrived. "In the database read/write vi provided with labview, this error occurs each time series. In mine, I joined, I would get this error once every nine or 10 times by operating once every time. Sometimes the error would be to present the first time that I pressed the race, but after I click OK, the next run will work fine until about the tenth times.

    Does anyone have any idea why this could be implemented? I really just need to be able to read the pressure, temperature and CO2 with precision as well as several times without problem.

    Thank you very much!

    Ok. So I solved my problem with a co-worker, but he had a miserable time. I think that the VI attached work a LiCor-820. I think that you can fix the buffer problems of overflow to everything in a while loop with an error handler. Basically, the error handler can prevent display errors, and at the same time, it can also make a stop or continue the condition for the while loop. I chose to continue after deletion of the read buffer until it wasn't a mistake. I took a loop because the data on the first launch is usually just a partial reading of the data set is past the LiCor. I know that this probably isn't the most elegant solution, but it works for this situation so far.

    Thanks for the comments and suggestions of each.

    If only it was not fixed, so it's more probablyy caused by an Antivirus/Firewall. Symantec Antivirus seems to cause this issue often (as well as other AVs). In this case, try to disable the mailscanner in your Antivirus and see if that solves the problem. Or disable the Antivirus add-ins related via Outlook. See here how to proceed:

    Probably the installation media itself is corrupt. If your Alienware is preinstalled with Windows 7, then you should be able to reinstall using the recovery partition:

    New computers that come pre-installed with Windows often have what is called a recovery partition. This is used to reinstall an operating system in the case of a system failure. To access it, you need to start when you start your computer by pressing a function key. This can be either F1, F2, F9, F10, F11, F12 key DEL or tab. See the manual that came with your PC for instructions on how to reinstall Windows.

    To restore the image while preserving the data files:
    Turn off your computer.1.
    Disconnect all devices connected to the computer (such as USB key, 2 printer and so forth) and remove any recently added hardware in-house. NOTE: Do not unplug the AC adapter cable.
    Turn on your ordinateur.3.
    When the Alienware logo appears, press several times to access the 4. Advanced Boot Options window. NOTE: If you wait too long and the operating system logo appears, continue to wait until you see the Microsoft Windows desktop; then, shut down your computer and try again.
    Select 5. Repair your computer.
    Select 6. AlienRespawn and backup emergency in the System Recovery Options menu and follow the instructions on the screen. NOTE: The restore process may take an hour or more depending on the size of the data to be restored. NOTE: For more information on AlienRespawn, see article 353560 at support.Dell.com knowledge base.

    If the recovery partition does not work:

    Step 1: Download a copy of Windows 7:

    For 5 years, Microsoft made it fairly easy for users of the Windows 7 operating system to get reinstall media. If you have lost your support disc or installation retail collection; either it has been damaged or defective; You can download a copy of the edition that you have licensed from a membership site called Digital River. More recently, Microsoft ended the availability to reinstall media that you can download as a. File ISO in Digital River, which is a digital reproduction of an optical disc.

    It was particularly convenient for people who could not easily get the manufacturer's recovery media, did not want to pay the fees required to get or preferred a clean configuration without the software packaged manufacturers or even a recovery partition does not work. It's easy to use, all you had to do was reinstall and reactivate using the product key located on the certificate of authenticity and download all the drivers on the manufacturers website.

    Given that this option is no longer available, what are your options? See the article for more details:

    How to: What are my options for Windows 7 reinstall media?

    Make sure you scroll down and read the section:

    What to do if you cannot get your manufacturer recovery media, refuse to use or to buy it or the Microsoft Software Recovery Website does not work?

    Step 2: Perform a custom installation, see Windows 7 section of the following article how to perform a custom installation:
