Frequent disconnects between cRIO-9024 and host computer

Hi all

I had a brand new cRiO OR 9024 and several modules of recording data a few days ago. I have setup the IP address for the cRIO which is 10.0.0.2 and the subnet mask is 255.255.0.0, which is the same with what I've done for the host (different IP address). I installed the software that I need on the controller RT. Throughout the process, I have disabled the firewall. I use MAX 5.0 and NEITHER cRIO 4.0. Two of them are the latest version. I built the link between the cRIO and my computer successfully. However, the target is always disconnected from the host computer, even if I do not have action on the cRIO, that is. Without running any software on it. Status of the disconnection is achieved since the MAX, but surprisingly, I can ping through the IP address of the cRIO. It seems to me that the connection between the host computer and the cRIO was established.

I tried to run code on the target, but unfortunately, the disconnection also occurs frequently simple. I checked the CPU target and the use of memory, which are low. So I concluded that the disconnection is not generated by the high utilization of the processor or memory.

I also tried to reformat the cRIO and reinstall all software, but it has no effect.

I also found that a warning appears regularly on MAX interface that "there was a problem to retrieve the settings of the target. For more information, go to ni.com/frinfo and enter the Info Code MAXServerUnkownError. If the problem persists, contact National Instruments'. I checked MAXServerUnkownError of

NI.com and followed the instructions to make sure that there is no bad configuration on my computer as a firewall etc. However, without doing wrong was found.

Can someone help me figure out what is the problem?

Hello Japanese,

Thank you for answering my questions. I have more questions that should lead to a solution to your problems:

1 is the add-on NO-time installed on the cRIO?

2. are you able to disable the antivirus on your computer?

The add-on NO-time turns out to cause frequent disconnects with cRIOs in LabVIEW 2011. To view the add-on, you will need to right click on software under the cRIO, select Add/Remove Programsand select the option custom software installation . If it is installed, I recommend to remove this add-on the cRIO to help solve disconnects.

Please let me know if disconnects continue after removing NO-time and disabling the antivirus.

Kind regards

Andrew Brown

  • VMWare Player 6 - copy / paste doesn't work is not between the guest and host

    Hi all

    I am unable to cut and paste (text) or drag-and - drop (files) between the client and host and vice versa.

    I am running Windows 7 (32-bit) guest on a host Windows 8.1 (64-bit).

    Everything else works to date works and VMWare Tools are installed.

    I spent a few hours searching and have not been able to determine if this is a known issue or just a mismatch in my environment/configuration.

    Hi all

    Seems I solved the problem.  It comes down to User Account Control (UAC) prompt (in my case Windows 7 (32 bit).  I have disabled UAC in the comments and drag and drop / cut and paste now works like a charm.

    Autologin also now works. I had not tried to set up that more early.  That's where I read an article to disable UAC for AutoLogin work.

    My VMWare tools icon now displays in the system tray.

    I hope this helps someone else out there!

    Thank you...

    NMAYO,

    Depending on your project can you right click on the chassis in the cRIO and make sure that it is set to the Mode Scan mode and not FPGA? In addition, in the solution of measurement and Automation Explorer, you can check the cRIO and check that it has the Support of Scan Engine is installed. The tutorial below shows how to reformat a cRIO and install the software on this subject, the subsequent steps in the software allow you to check your cRIO.

  • Is it possible to pass key code COST between my laptop and desktop computer?

    I have Vista Ultimate retail installed on my laptop and it came with disks of 32 and 64-bit. The Office has been an ultimate upgrade of a House of high range retail and only had the 32-bit disk.  Now that I've upgraded the office, it will easily run 64 bit. The laptop could never be upgraded enough to use 64-bit. Is it possible to change so that I could run the 64-bit on the desktop? Thank you.

    "I have Vista Ultimate retail installed on my laptop and it came with disks of 32 and 64-bit."

    You cannot use both at the same time.

    Read this:

    If your computer is pre-installed with Vista, it is classified as an OEM license and is not transferable.

    The license of Vista OEM is related to the original computer it is installed on and dies with the computer.
    You cannot transfer it to another computer/laptop

    If a license of Vista at retail, you can transfer it to another computer/laptop.
    But it can only be installed on one computer at a time.

    A single license is a single Installation.

  • Frequent disconnections of WLan on satellite M40X-230

    My laptop undergoes frequent disconnects on the internet and it becomes very annoying. Situation is that the laptop connects wireless to the Internet via a Belkin router. The router works well, and I use Aol for the ISP.
    Our second laptop, also a Toshiba but a satellite A30-203 does not suffer from problems despite using the same router.

    Two laptops have SP2 and the M40 is centrino mobile while the satellite has a card (also Belkin) wireless adapter.

    If I look at the connection speed, it varies between 54 Mbit/s and 1 MB/s and said that the signal strength is excellent regardless of speed. This means that the problem lies in the laptop or its parameters, or must he chipset drivers upgrade?

    Any help would be appreciated as the slow performance especially when loading pages on the net makes me stupid.

    Hello

    You should know that there are different standards of WLan that supports of different properties.
    The standards are 802.11 A, B or G. Currently, the standard 802.11 G wireless supports the fastest connection.
    The best combination is the using the router and wireless network adapter that supports the same standard.

    You suggested that the A30 Satellite using the Belkin WLan adapter. I guess it has better compatibility between router Belkin and Belkin WLan card. As a result, you will get the best performance.

    However, on your satellite, you must check the WLan card properties. There you should find a few options that could increase performance card and connectivity.
    Important: Energy saving Option should be disabled in the properties of the map. Try also to set the WLan range at the highest level.

    In addition it s advisable to check the WLan card driver updates. If you use a map control WLan Intel the Intel page for updates.

  • Choose the network protocol for CRIO-9024 to PXI on Ethernet

    We are in the design phase, implementation of an embedded controller for CRIO-9024 to send data captured at an SMU-8105 on ethernet controller. The data will be arrays of double-precision 2D. These data should be sent to the pxi at the end of each test step. Each stage will have a different number of channels and sampling frequencies.

    For example, Test step 1 will have 5 channels of analog inputs that will be sampled to 100,000 KHz for 1 second. These data will come from the CRIO FPGA. Data will be get dealt with by the CRIO-9024 and analyzed post to pass or not not metric. Then, the CRIO controller will send the data 2D (data points 500 000 5 X 100 000) table and the results of all the measures (a table 1 d) for PXI.

    The connection with the PXI will use Ethernet.

    Do not forget that the PXI should also send the CRIO certain values to tell the CRIO when starting the test, and when the test sequence is completed.

    I thought that TCP/IP would work better because of communication 2-way necessary. But then I was watching streaming network or even using shared Variables.

    If anyone has any ideas or suggestions please please post them.

    Hello

    You can use either.  If you are more comfortable with really.  The STM method will be a little less overhead on my style XML tagging data, but it will be very short given the size of the data.  Probably go with STM has it right most of the work for you.

    Regarding the size data the you must normally transfer data as this is to flatten to a string.  If you convert a string of numbers readable human you will either lose accuracy, increase the size or both.  Because the string after that flattened will be the same size as the original array anyway for the quick calculation based on your previous post 500 000 double (8-byte) is 4 miB (3.8 MB)

  • Office of ping and distance between the player and the second computer

    I have a laptop running VMWare Player 12 (NAT) and a PC connected to a router.  All 3 running under Windows 7.  All firewalls is turned off.

    Win 7 guest may ping the laptop computer, the router and the PC.

    Portable Win 7 can Pinger the PC, router and Win 7 guest.

    The PC can ping the router, the laptop, but not the comments of Win 7.  Why not?  (Ping results in a timeout or a "Destination host unreachable")

    I can run Remote Desktop from the laptop at the prompt of Win 7, but I can not run Remote Desktop on the computer in the prompt of Win 7, which is what I'm really after.  Why not?

    Remote Desktop between the PC and the Win 7 guest would not work any direction.

    For other reasons, I must leave the network connection of the player in NAT mode.  Ping and remote desktop work fine in bridged mode.

    I ended up adding a second card (bridged) network under Remote Desktop and devices that I can use to ping and the application that is using NAT also works very well, so that solved my problem.
