OPEN TCP 63 CONNECTION ERROR

Hi all

I got an error 63 when running in my case. Basically, I build this case LabVIEW as a station master to speak the prorocol Modbus slave device and now read the registry of her value.

The thing is that my computer can talk to the slave, I used the other monitoring software to detect as you can see in 'the slave data '. But in labview, I do not see data slave because of this error.

I don't know if it's because of something wrong with the code itself.

I hope all of you who are familiar with the implementation of Modbus labview could help me or!

Thank you!

Jinrong

Error 63 is usually thrown when there is no "listen" for a connection.  You have a standby server on a TCP connection to the IP address you provided?

  • Open TCP/IP connection failed

    Hello

    I can't establish a TCP/IP connection between my host and another PC. I use the 'Simple data Sever' and 'Customer of data Simple' screw delivered with LabVIEW. Error message is less than

    The example screw working finw when I use them only on my host.

    I can confirm the following:

    • Good serial port
    • Correct skill game
    • The firewall on both computers is OFF

    Any fix ideas?

    Try a port number more than 50000. You use port numbers in user space. 2055 port is assigned to the Iliad-Odyssey Protocol and commplex-link 5001 is assigned. Don't know what eith erof here is or how they are commonly but you might be runnin celine a conflict. Ports 49152-65535 are reserved for dynamic/private use. You can get more information here about IP ports. It's worth a try. The other thing you could do is to install Wireshark on every PC and see if the package (TCP - SYN) is to learn by the client and the server.

  • Cannot open new internet connections after running WMP (existing stay open)

    Hello.  I'm having a strange problem when I run Windows Media Player 11 on Windows Vista Ultimate (64-bit).  It does not immediately occur, but whenever I run WMP, my internet connection will be some time after you cease to be able to open new internet connections - for example, I can't open the Web Pages in Internet Explorer, my Sidebar gadgets can not update and such, but my IRC client remains connected to his server (although I can't connect to a new server).  As I said, my internet does not die immediately, it might take an hour or two, but if I run WMP and that he do nothing else whatsoever but leave my computer for once it is a guarantee that this problem occurs.  To fix that I can understand, the only way is to restart.

    I read something about what is possibly caused by WMP somehow using up to the maximum allowed simultaneous incomplete tcp/ip connect attempts, but it should be originally the 4226 error code is not present when I run the Windows Event Viewer.

    I use Avast! for my virus scanner and I have BOINC/SETI @Home running in the background.  Turn it off does not seem to make a difference, however.  I'm not under any P2P software.

    Any ideas on this annoying problem would be greatly appreciated!

    Hi Jpetrisor,

    I also suggest you to re-record the files related to Windows Media Player and check

    Step 1:

    To do this, follow the steps below:

    a. Click Start, in the start search bar type cmd, right-click on the command prompt icon in the box programs and then click Run as administrator.

    b. at the command prompt, type the following commands.

    Type regsvr32 wmp.dll, and then press ENTER.

    Type regsvr32 jscript.dll, and then press enter

    Type regsvr32 vbscript.dll, and then press enter

    c. restart the computer and check if the problem is resolved.

  • Want 4500: Connection error! The printer could not connect to the server

    Connection error! The printer could not connect to the server!

    Cannot set up eprint or update the driver. Ever been on the forums and do not understand what to do!

    I am successfully connected to my router and can print from my pc and my ipad with airprint.

    PC "will not find"the printer either for purposes of updating

    What I need to change the DNS. If so, I don't know what it is or how to do it!

    I went to the ip address but was unable to click on "wireless (802.11)", as recommended by a last response forum, as the next low 'status '.

    Can anyone help?

    Very frustrated customer :-(

    Hi @roopuk,

    Thanks for getting back to me.

    Sometimes the manual DNS 8.8.8.8 / 8.8.4.4 won't work in some configurations of network users.  Try the same steps as described above, but this time use the following parameters:

    Manual preferred DNS Server: 209.244.0.3
    Auxiliary manual DNS server: 209.244.0.4

    If you encounter the error, as before, we take our proverbial gloves off to try a more intensive troubleshooting.

    What is happening, it is that your router allows your printer connection that to enable wireless, but not a secondary connection to Web services.  In order to get these devices to 'shake hands' a second time, you may need to enable DMZ mode on your network through the router's built-in Web server.  HP does usually not this configuration for its customers as errors can cause serious network problems, but I can certainly post the info you need on your router or the ISP of the staff support company so that they could help you directly.

    Here is the information that you need for your provider service to open ports on your router/modem...

    -Multicast must be enabled
    -Hello enabled for AirPrint (relevant for iOS and Mac OS users)
    -Mac filtering should be disabled
    -Also, make sure that your router's firmware to date if
    necessary
    - The dmz on the router mode and turn it on to the printers IP address: _

    Ports to open are: Eprint and Apps

    Incoming Ports.

    UDP
    80
    443
    ------------------
    Outbound ports

    TCP
    5222
    5223
    -------------------
    Once they are open, you should have no problems connecting to services web eprint on your device.

    I would like to know how it works for you.

    Kind regards

    4. Add a static DNS 8.8.8.8 and 8.8.4.4

    5. I restarted everthing in the House.

    However, the printer works fine on PC Windows 8 and the iPad or the iPhone.

    Please help as we would like to again access coloring Disney pages.

    Well, try to change the network ipv4 only protocol

    you need to get the ip address of the printer first, and then open any web browser, then try typing the ip address of the printer on the url, after that go to the network tab > networking > network protocol > check on ipv4 only > apply

    If it does not work.

    try going into the menu of web services and delete web services and then re-enable back.

    Hello

    Thanks for posting your query on the Microsoft Community.

    I would be grateful, if you can provide us with the following information to help us better understand the question?

    1. Did you do last changes before this issue on your system?
    2. You use a third-party security software on your system?

    I suggest you to follow the below methods and check.

    Method 1: TCP/IP can sometimes become damaged or altered. We can refer to TCP/IP and check if this solves the problem.

    How to reset the Protocol Internet (TCP/IP)

    http://support.Microsoft.com/kb/299357

     

    Method 2: I suggest you temporarily disable the antivirus software (and other security such as anti-malware software, etc.) and the firewall on the computer and see if that fixes the problem.

    If disabling the antivirus/firewall resolves the issue, you may need to configure the settings of the antivirus as a result program. Please contact the software vendor for assistance in this regard.

    Note: Make sure that you enable the antivirus software, other security and firewall after the test programs.

    Caution:

    Antivirus software can help protect your computer against viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to disable temporarily to install other software, you must reactivate as soon as you are finished. If you are connected to the Internet or a network, while your antivirus software is disabled, your computer is vulnerable to attacks.

    Hope this information is useful. Please let us know if you need help with Windows.

    jfusco,

    If you have an IP address manually, assigned to the printer:

    1. Enter IP address of the printer in the Web browser address bar and press ENTER.
    2. Go to the network tab and the IPv4 Configuration of the page.
    3. In the DNS server settings, the entry in your domain DNS servers or put IP of the router Address in the preferred DNS server and 0.0.0.0 or 8.8.8.8 in the section auxiliary DNS server and apply the changes.
