Whats the maximum achievable speed of data transfer from RT to host PC

Hi
    Anybody can tell me whats the maximum achievable speed of data transfer from RT to host PC, in case of both PXI and CompacRIO.
Regards
Visuman

Hi visuman,
To be honest, the dataspeed is dependent on how you architect the code, and the data communication channels that you use. 
There are many factors that influence the maximum transfer rate, including network topology, types of interface used, OS, ambient network traffic etc. 
You can control two things, packet size, and amount of sleep time between transmissions. 
By altering the delay between consecutive TCP/IP transmissions and by varying the packet sizes sent from the embedded side to the host side, you can obtain a clear picture of network characteristics between the two devices. The end result is a report of the optimal TCP/IP configuration, that is packet size and sleep time.

Here are some other links that maybe useful for you.

  • Online data transfer from R/3 to APO

    Dear friends,
    Can any one help me? What is the transaction code for online data transfer from R/3 to APO?
    Material master;
    BOM;
    Work Center;
    Routing;
    Production version.
    My understanding is to create integration models and activate them:
    /CFM1
    /CFM2
    /CFM3
    Once it is activated I will be able to see the Master data, Material Master, BOM, Workcenter, Routing and Production version in APO?
    Thanks
    Raj

    Hello Raj -
    If understand you are saying that the a batch job is run every 12 hrs to send in the master data from r/3 to APO?
    if thats the case then you have to wait to see the changes or the material that you are trying to CIF till the next batch runs through. the steps tht you have described are right
    Create the integration model.
    activate the integration model.
    there are settings in there where you can transfer the data real time also, but i guess your project is not using it.
    Hope this helps.

  • What's the maximum LAN speed with the Thunderbolt to Gigabit Ethernet Adapter on my MacBook Pro?

    While I was at Yodobashi Camera yesterday, I got a Thunderbolt to Gigabit ethernet adapter for my MacBook Pro. I figure, since I'm paying for the high speed fiber optic (Sony Nuro), why limit my self to wi-fi speeds at home?
    Before connecting the adapter, via wi-fi it the speed was 143.8 Mbps down and 181.5 Mbps up.
    After connecting the adapter and making a direct LAN connection to the router, the speed is 783.2 Mbps down and 940.1 Mbps up.
    I'm certainly happy with the speed, but since Sony Nuro is supposed to be 2 Gbps down and 1 Gbps up I was wondering what the maximum possible is with this computer and adapter. Before asking the provider I was curious what the maximum specs where.
    The ether cable is a 3 m category 6.
    Thanks,
    doug

    It's not really your computer that is getting the 2Gbps download - it is the router/ modem.
    If you hooked better/ different hardware up you could probably push those speeds around your network too. The trouble is that most residential hardware is gigabit ethernet not fibre. Fibre cards & cable are expensive in comparison.
    The existing hardware may allow you to 'bond or aggregate' multiple ethernet connections into one link to get more speed over ethernet. Obviously this requires more complex routers, switches & a network admin to set it up
    Those speeds sound nice, this bottleneck will mean that other devices on you network can't choke up the whole connection & make other users sad.

  • Problem with 'maximum achievable speed'

    Hello,
    I'm hoping you'll be able to offer me so helpful advice. 
    I'm an Orange home broadband customer, which I believe is provided through yourselves. When I signed up to Orange they stated I could expect speeds of up to 20mb. I live as close to the exchange as you could get really. On my online account it states - "The speed estimate at registration or the speed we have measured on your line is 14.0Mb"
    For the first couple of months I was regularly getting speeds of 8-10mb. To be honest I'm perfectly happy with anything over 2mb. 
    However, recently my speeds have been always on the 1mb mark, causing buffering for iPlayer, youtube etc. Having run the BT Speedtester, I find that my maximum achievable speed seems to have been capped at 1mb. What would be the reason for this? I've read my terms and conditions and have not exceeded any bandwidth levels, I don't even download songs, let alone movies.
    How do I go about getting this 'maximum achievable speed' back to how it used to be?
    Thanks!
    Download  Speed
    927 Kbps
    0 Kbps
    1000 Kbps
    Max Achievable Speed
     Download speedachieved during the test was - 927 Kbps
     For your connection, the acceptable range of speeds is 400-1000 Kbps.
     Additional Information:
     Your DSL Connection Rate :1148 Kbps(DOWN-STREAM), 1160 Kbps(UP-STREAM)
     IP Profile for your line is - 1012 Kbps

  • Can anyone explain the mechanism of  data transfer from r3 to bw?

    Hi all the bw expert,
    i have one question on the mechanism of data transfer from r3 to bi 7.0. the followings is my concerns:
    scenario:
    The total numer of data is 1000 rows and these rows are seperated into 10 data package , each package contains 100 rows.
    Now  bw is trying to recieve these 10 packages from r3 in sequence.
    When  5 data packages have been transfer to bi psa. the network is broken and the tranfer is canceled at the 6th data package.
    What i want to konw is when the network is reconnected ,Does the transfer start from the 6th data package?
    Please help me to explain all these. Is there any material or links can be used to understand this feature?
    Thanks ahead.

    Hi......
    Connection broken means load failed.......extraction is cancelled.......
    If your load is delta........then make the QM status red in the Infopackage........and repeat the load........
    If your load is full........(in case of full upload it is not mandatory to make the QM status red..........but ii is a good practice to make the qm status red)
    then repeat the load........
    But before repeating the load plz check the connection in SM59............if it is ok then repeat..........otherwise wait for som time.......If still in connection is not ok then contact basis people.....
    Regards,
    Debjani.......

  • Is there is any way to find the data transfer from client to Configuration Manager for health monitoring and hardware Inventory

    Hi
    Can Configuration Manager provide a way to find the data transfer from client to Configuration Manager for health monitoring and hardware Inventory. How can I know what amount of data is consumed during that process

    Place archive_reports.sms in %systemroot%\ccm\inventory\temp\ for both 64-bit and 32-bit computers.
    There are two situations where you can use this depending on the type of client:
    1. To keep inventory reports on a client (that is not an MP), create the following file:
    %systemroot%\ccm\inventory\temp\archive_reports.sms
    2. To keep inventory reports on a MP (that is also a client), create the following file:
    <x>:\sms_ccm\inventory\temp\archive_reports.sms
    The XML file will be saved in the inventory\temp folder.
    More information on the above here: http://blogs.technet.com/b/configurationmgr/archive/2012/09/17/controlling-configuration-manager-2012-using-hidden-files.aspx

  • Whats the maximum resolution resolution supported @ 60 Hz on an external display for mid 2014 macbook pro retina 13 inch ?

    whats the maximum resolution supported @ 60 Hz on an external display for mid 2014 macbook pro retina 13 inch ?

    I don't know where you found 1920x1080, but that isn't the max. The INTERNAL display can even support more than that.
    The maximum resolution is really hardware based, and since Thunderbolt 2 has a Mini displayport connector (Mini Displayport 1.2), the max resolution for Mini Displayport is 4k (3840x2160).
    PLEASE NOTE: Not all adapters can support that resolution, most monitors that can run 4k @60Hz have Displayport 1.2 (The most recent revision), Mini Displayport 1.2, and HDMI 2.0. DVI dual link can run 4k, but only 24-30Hz, depending on the monitor.
    Hope this helps!!

  • What's an easy way to determine what the user typed is a date object?

    What's an easy way to determine what the user typed is a date
    object?
    Thanks!

    Thanks for trying. Sorry for not being clear. but I figured
    it out.
    the user can type in a date, or a name to search. The format
    they type in date has to be in mm/dd/yyyy.
    I was able to use:
    if (new Date(textEntered).toString()=="Invalid Date") {
    // not a date entered
    else {
    // a date is entered
    To do what I need to do.
    Thanks.

  • Whats the maximum length array and why?

    Whats the maximum length array and why?
    I tryed to search the forum but most people was wondering about the maximun length of a String..

    for(int i =20;i<=32;i++) {
         try {
              int[] p = new int[(int)Math.pow(2,i)];
              pause(2000); // So that gc doesn't clean away the array before
                              // The OS memory manager gets to update.
              System.out.println("Paused! i: " + i);
         } catch(OutOfMemoryError e) {
              System.out.println("Ex!!");
              pause(10000); // Same sa before.
    void pause(int p) {
         try {
              Thread.sleep(p);
         } catch (Exception e) {}
    }I worte this little code to test this.

  • Time Machine Data Transfer - From FireWire Drive to Time Capsule - HELP!

    Time Machine Data Transfer - From FireWire Drive to Time Capsule - HELP!
    I've been searching for weeks for a solution to my problem. Here's the story I've come across since I installed Leopard on Oct. 26, 2007.
    I first installed Leopard on my Early 2006 MacBook and set up Time Machine with a 200GB external FireWire drive. Since then, things have been fine, until Time Machine started deleting the oldest backups. I'm a pack-rat and hated this feeling of losing data. So, I now have a few months worth of backups on my 200GB FireWire drive.
    The Time Capsule is released, I finally talk myself into getting one and transferring my old data from the 200GB drive to my 1TB TC.
    I did some researching through forums about how to move data from one Time Machine drive to another, so I took the concept and wanted to apply it to my Time Capsule. I made a DMG image of my 200GB drive, in order to move the data. I figured if I can make an image, copy it, and open it on the Time Capsule - all will go smoothly - just as some had mentioned they've done with external drives.
    Now, I have a 164GB DMG image of my Time Machine, with no hope in sight of gaining it back. I've tried taking the image, using Disk Utility, and restoring my original 200GB external with the imaged Time Machine data, but whenever I do, I come across error messages.
    In Disk Utility, I've done the following steps:
    * Disk Image is found on Time Capsule
    * I select the 200GB drive and select 'Restore'
    * I drag and drop the Disk Image to the 'Image' field
    * I drag and drop the 200GB drive into the the 'Restore' field
    * Select 'Erase Destination'
    * Select 'Restore'
    * I get the warning message that I'll erase the drive - I proceed
    * I enter my password
    Error message pops up:
    "Restore Failure: Could not find any scan information. The source image needs to be imagescanned/scanned for restore."
    I select the image in Disk Utility, then proceed with the following steps:
    * Click on "Image" then down to "Scan Image for Restore"
    * I enter my password
    After hours of waiting, I get another error message:
    "Unable to scan. (Broken pipe)."
    I'm going to see, after transferring the DMG to the Time Capsule, if I can drag-and-drop the files from the Time Capsule drive onto the 200GB hard drive.
    IF anyone has any more suggestions, please let me know!

    32 updates on this Mac since December 2007 - Hardware, software, OS...
    They keep coming at about 6 or 7 a month. Some of them I don't care about, but several are essential. 10.5.3 has been seeded to the testers a couple of times and will probably show up in the next few weeks. Jaguar wasn't worth a d*mn until 10.2.6, Panther about 10.3.4, Tiger about 10.4.4 - I'd say we are ahead or on schedule Too bad I can't get Apple to fix Spaces. I wish they'd focus on what I want but I guess some take more time than others.

  • Data transfer from CRM to R3

    What exact data transfer from CRM to R3, on completion of a sales Order. I am new in the field, need some good example?

    HI Sajjad,
    Transafer of order from CRM to R/3 involves following activies.
    Setup RFC destination between CRM & R/3
    Create a R/3 Site (Transaction: SMOEAC) and assign a subscription named
    (Sales Document (Mesg) created from publication Sales Document(Mesg)).
    In R/3 maintain Document type with same name as Transaction type in CRM, item category with same name as item category in CRM, Item category determination with same as in CRM.
    Master data i.e. Product in CRM should be present with same name as material in R/3. BP in CRM should be present with same name as Customer in R/3
    Organizational data is maintained in CRM.
    Best Regards,
    Pratik Patel.
