Serial communication: write the message exactly once?

Hello. I use the example of reading of continuous series and Write.vi in LabVIEW, and I want to change so that I don't write a single message, rather than have to write continuously. How can I do this? I tried to find a way to do it, but the problem is that I have very inconsistent results with re-reading what I send, so I don't know what actually works and what is not. What I think works is affecting released mechanical write lock switch when action, which seems most of the time... but sometimes, when I click on Read I get nothing after writing.

Do not use a switch or a case structure at all for reading.  Just let it read.

You are better off putting him write and read in the structure of the case for the write button.  You click the button, he writes.  It reads, if you can't fit anything in the period, it would certainly be a problem with your device or cable rather than with LabVIEW.

  • Serial communication cause the crash of LabView

    Hello

    I'm set to do a serial with Labview. The problem is that the program always crash (no popup error but only LabView don't freeze) when I read or write with VISA.

    I work with a module converter (ADAM 4571) that convert Ethernet to RS-232/422/485. The module is mapped to the computer and the similar work as a COM port. I tested the connection with the Terminal windows and its work. This means that it is not a hardware problem.

    I did the same communication a few weeks with the same material and did not have a problem. I don't understand why it does not work now.

    I give my code as an attachment, but it is not something special except for the block that buffered (which is required for my module), but if I remove it the problem persists.

    Does anyone have an idea what can be the problem?

    Thank you

    Jérôme

    OK, I solved the problem.

    The version of the driver for the converter module mapping was not exactly right, now I change it and its work.

  • Serial communication - ignore parity error

    I have a question about how LabVIEW opens a serial port for communication. I communicate with a device that uses a protocol owner. It sets and clears the parity bit to indicate the nature of the response. For example, the orders are sent with the parity bit higher while responses are sent with the weak parity bit (unless the answer is at the end of the transmission, in which case the device sets the parity bit high to indicate).

    My problem is the way that LabVIEW opens the serial port for communication. Using Portmon, that I captured the control indicators, that it sends to Windows to configure serial communication:

    IOCTL_SERIAL_SET_LINE_CONTROL   Serial0 SUCCESS StopBits: 1 Parity: MARK WordLength: 8IOCTL_SERIAL_SET_CHAR  Serial0 SUCCESS EOF:0 ERR:0 BRK:0 EVT:0 XON:11 XOFF:13IOCTL_SERIAL_SET_HANDFLOW  Serial0 SUCCESS Shake:1 Replace:44 XonLimit:64 XoffLimit:64
    

    Note the values 'Shake' and 'replace '. In my view, they are originally bytes with parity errors is removed. A separate RS232 Comm Debug tool that I use with success looks like this:

    IOCTL_SERIAL_SET_LINE_CONTROL    Serial0 SUCCESS StopBits: 1 Parity: NONE WordLength: 8IOCTL_SERIAL_SET_CHAR  Serial0 SUCCESS EOF:0 ERR:0 BRK:0 EVT:0 XON:11 XOFF:13IOCTL_SERIAL_SET_HANDFLOW  Serial0 SUCCESS Shake:0 Replace:80000000 XonLimit:128 XoffLimit:128
    

    Notice the difference in values. By using this tool, Windows does not packages with parity errors - that's what I want. Is there any way to change how LabVIEW opens the serial communication port to achieve?

    I tried to change the parity, where the ILO is defined differently, but I think that I am running in a race condition; LabVIEW can not run the code and change the mode of fast enough parity before the next byte of data is sent by the device.

    Ravens fan: the parity bit, in the proprietary protocol, that I use, is not used for parity checking. Basically, the protocol uses a 9-bit serial communication. The parity bit must be paid or compensated according to what byte do (if it is a command, if it is the end of transmission, etc.).

    I found an old post on this page which seems to answer my question (my apologies for not completely research before posting... I learn the right use/search phrases that I find more information). I download the 3.4.1 version of VISA now.

  • The message body disappears when you change ' send to ' account (MS Outlook 2007)

    I had a problem with a bug recently that does not previously exist, so it must be from a recent update (I always keep all my software up to date). This bug is very annoying.

    I use multiple e-mail accounts and they are all downloaded (POP3/SMTP) and managed by Outlook. Whenever I write a message and change the account "send to" to have the email sent from another account, that the entire message disappears - I start to write the message again. I am generally able to save the message either through projects opening or using the key ctrl + z function, but a little now and then I can not find the message. So I'll have to rewrite!
    Is that what I can do to solve this problem, or is some additional 'characteristic', written in one of the updates? Help, please!

  • what I have to write the serial number. before you download a driver for my printer?

    What is the serial number helped and I have to write down it before you download a driver for my printer?

    I have my printer and I want to download the driver that is related to my printer, I searched but did not find where I can write the serial number to reduce the possibilities of the wrong driver.

    There were also 3 options after that I named my printer:

    1. HP Officejet 4500 all-in-One Printer - G510g

    2. HP Officejet 4500 all-in-One printer - G510a

    3. HP Officejet 4500 Wireless all-in-One Printer - G510n

    I don't know what I should choose.

    Best regards

    So, you can use the Installation Wizard of HP printer if your using Windows 7, 8 or 8.1.

    If you have any of the above operating systems, connect the printer to your PC via the USB port or connect it to your network.

    Then run the next tool that will detect your connected printer and download the correct driver for it:

    If you have any other operating system, please specify your printer model exactly as shown previously.

    Kind regards

  • If I click once on an e-mail in the message window while I closed the preview window, I opened that makes e-mail?

    If I click once on an e-mail in the message window while I closed the preview window, I opened that makes e-mail? I worry because I don't want to open a message that my bad-ware download on my computer. If the preview window is closed, I noticed that the number of e-mails read does not change when I click once on e-mail. Can I assume that unread means that it has not been opened.

    Read the answer! Your question is answered there.

    Read / unread is purely an indicator. It has no real meaning. If you go into the menu (alt + T) tools > options > advanced > reading and display, you can change when a mail is marked as read in immediately to 10 seconds (this is what outlook express used) up to 1000 seconds.

    The software marked the email read is that this logic can go. It's always "BOLD", the software did not mark the message read.

    You open the mail? It is an unquantifiable statement.

    In the context of Thunderbird an individual mail is not a discrete element that is stored. It is a part of your data for mail/News. So try to equate open to action just does not fit.

    Thunderbird received mail as a series of lines. He collected in an email that he stores in a file with all your other emails for this folder. You open the file in that the mail is stored? Totally irrelevant Thunderbird opens to get mail every time that mail is added to the folder or to view a mail in this folder.

    Each time a letter is displayed (any mail) the file all your emails for this folder are saved in the opening and reading.

    If clicking on the mail list 'open' the file. Probably not, it was probably already open. The file is opened, read, written to and updated probably half a dozen times since Thunderbird started so if you click on the mail to see won't change anything good at all. If the e-mail file has been closed it will be open to view the contents of the mail, but he is perhaps already open.

    The key is that you try to apply assumptions to mail that simply do not apply. That's why I sound as if I'm going in circles.

    You also may ask, when I fill the kerosene tank my electric light.

    • The software mark mail as read when you say
    • It opens files underlying storage constantly. Clicking on an entry may or may not cause the opening of the file.
    • Your mail is not in a file on its own, it is in a file that contains all the messages in the folder and the mail deleted until the folder is compacted.
  • As of the 31 version, why is there still no option of Thunderbird to insert the date and time in the message that you write?

    As of the 31 version, why is there still no option of Thunderbird to QUICKLY insert the date and time in the message that you write?

    Literally, saw this option very well needed - and opportunity-"promise" for three years now, and even if there are only one or two formats that could be used, at least the option is there.

    It seems that only is to bind a Macro, and the tool to Thunderbird and do it this way.

  • Save the data of State machine after each iteration, then write all the data at once

    I have trouble finding in the best way to manage data generated by my state machine. Here are the data that it will save:

    * When pressure is set, a set point is returned.

    * When the pressure is set, a reading is taken a multimeter.
