Shared varialble FIFO -- ensure no lost of data

Hi,
      I would like to use network shared variable to send data from a VI ont the RT controller of my CompactRIO to the Host VI that runs on my computer. I did a like VI to understand the way shared variable works but I didn't find the right properties to ensure that I'm not losing the data. 
Does somebody could help me with that?

Network Streams in LV 2010 are designed for lossless data transfer.  NSV's do not guarantee to be lossless, you would have to add a data index count to a data cluster so that integrity could be verified.  There are examples of lossless tcpip RT->Windows transfer at ni.com.
Another thing to consider is that sometimes you do not need data transfer to be 'lossless' to have a good record of physical data on the rt.  In my case I use the cRIO scan engine to update IOV's at 40Hz,  I then transfer IOV data to cRIO hosted NSV's which are bound to windows hosted NSV's which in turn are set to log to a citadel database.  In effect I am getting a final 20Hz 'sampled' data stream into my DB.  Does my system guarantee that a 50ms signal transient will always get caught and logged in the DB?  No is does not, but for those kind of issues I usually rely on rt processes to catch such events and generate alarms.

  • Changed to "Securing shared disk: with accounts" and lost previous data?

    I installed a TC in July and have been doing Time Machine backups to it ever since. Today, I decided to add File Sharing accounts using the Airport Utility. I created two accounts. The next time Time Machine ran, it failed on login. I reconfigured it to use one of the two new accounts, and (not surprisingly, in retrospect) it began a complete, new backup.
    The Finder tells me that 150GB of the TC disk is already in use. I hope that's the space used by my former backups... but how do I find them? Whenever I try and open the TC in the Finder, I'm prompted for one of the new account/passwords, neither of which allows me to view any of the former data.
    Is it possible to access data that was written to the TC disk prior to my switching to account-controlled file sharing?

    Actually, it turns out it was still there and accessible. I went back to Airport Utility and switched "Securing shared disk" back to using a disk password, as before, and there was the "full" disk . . . containing my original sparseimage file, as well as a new Users folder and a Shared folder. The latter contained the sparseimage file from the new backup.
    I hope that I can replace the new sparseimage file (in /Shared) with the original one (in /), and switch back to using accounts to control access to the TC disk.

  • Loaded ios 6 onto my i phone and lost all data can it be retrieved

    loaded ios6 onto my i phone and lost all data. not too worried about apps but lost contacts, all music downloaded onto i phone and photos, Is there any way it can be retrieved?

    Welcome to the Apple Community.
    You can only restore them from a backup. This has occurred because you are sharing an iCloud account. ideally you should each have your own iCloud account, that way you can each manage your own mail, contacts, calendars, documents etc and avoid unintentional deletions and unwanted editing. If there is information you wish to share between you, this can be done with a secondary account.
    Having separate iCloud accounts, doesn't mean you have to have separate iTunes accounts, so whilst you keep your personal data separate, you can continue to share music, apps, books, TV shows, movies etc.

  • Lost all data on computer, want to sync back from iPhone

    Hello, first of all thank you very much for helping me, and sorry for my bad english.
    I have a iphone3g which connects to windows Xp trough an itunes 9.0.2.
    My problem is:
    I had to format my hard disk so I've lost my itunes libray and all files wich were included it. By the way I've reinstalled the iTunes. I've found an older libray and sat it up iTunes to use that folder/libray.
    The only problem is that this libray has an 50% diference that my iPhone has. I mean the half of the files (music, movie,calendar etc.) are different. I noticed it when i connected my iPhone to the iTunes, because iTunes wanted to replace all my sings and applications on my iPhone as it is on the (old) libray. I've noticed it and disconnected my iPhone from the CP.
    I've tired to create a new fresh empty libray and copy all my media from my iPhone to the new libray. But it said the iPhone could be connected just one lbray. (Which seems to be my "old"libray.) I dosnet want to connect my iPhone to the old libray because it will cause the loss of the half of my songs. I neither cant find the libray which is the same as the one on my iPhone nor copy my songs to a new libray.
    My songs were not imported to the itunes libray folder but were on their own place. It means that I have not lost my data, just the configuration (playlist, rateing, playcount, wich files were selected to add to the itunes, !applications! , etc.)
    Oh yes, there is an other thing. My newly bought applications were synced to the lost libray, and they could not be found in the "old" one, just on my iPhone. But as i said, I can not connect my iPhone to a new libray.
    I hope I've described it well, and you can help me please.
    Waiting for your answer.

  • HT3529 I have lost all data on my iphone and the back-up is too old. How can I restore iMessage chats on my iPhone 4? I have all the chats on my Mac, but there seems to be no sync function from Mac to iphone. Please advice.

    Hi,
    I have lost all data on my iphone by mistake. I needed to restore the phone and I didnt realize my back-up was 1yr old, and now the phone is restored and I've got a year old contact list and iMessage chat history. Luckily my iMessage on the Mac is still valid and has all the chat history. My question is how can I restore iMessage chats on my iPhone 4 from my Mac? I have all the chat history on my Mac, but there seems to be no sync function from Mac to iphone. Please advice.

    If things seem to be going haywire with your phone, it seems that it MAY be a software issue.
    Now, that being said, that does not necessarily mean that it is a virus. Software issues do happen sometimes. It is probably just coincidence.
    What you need to do is restore the device using iTunes. This will fix any software issues. After you have done this, you can restore from an iCloud backup.
    iCloud does not back up the actual software, so no, the "virus" would not have gotten into the backups.
    The link below provides steps on restoring your device using iTunes as well as how to restore from an iCloud backup.

    Don't worry! Everything should be back to normal if you follow these steps.

  • Partition with Disk Utility in 10.7, Lost All Data on Drive

    All,
    I partitioned a 2TB drive with DiskUtility.  Partition 1: 1.99TB, Paritition 2: 1GB.  Lost all data Partition 1.  Two years of family photos, videos, business communications and files, time machine backups, are gone.  What to do?
    The solution I have so far: downloaded "Wondershare Data Recovery," followed instructions, it is scanning drive.  Does anyone else have any experience with capabale softwares to use for this purpose?  How about some professional data recovery centers accross the US where I can mail in my drive, and they do the rest?
    In general, what do I do?
    Stressed,

  • Restore steps if lost some data files?

    I lost some data files in database and I am not sure what datafiles are. But one think sure is the control and redo log files are here. For this case, I don't have to restore contronl files and archivelog files. Please correct me if my idea is wrong.
    Steps as follows:
    ===========
    restore database;
    recover database;
    alter database open;
    Please advice if the steps are wrong.
    FAN

    Hi user623471!
    Yes you don't have to restore control, redo log and archive log files in the case that they are not lost. To find out which datafiles are lost do the following steps:
    <pre>
    sqlplus / as sysdba
    --Make a checkpoint
    ALTER SYSTEM CHECKPOINT;
    --query v$recover_file to see which files need recovery
    SELECT file#, error, online_status, change#, time
    FROM v$recover_file;
    exit
    </pre>
    Now start rman an restore only the files shown by v$recover_file.
    <pre>
    rman target /
    restore datafile x, y, z;
    recover database;
    sql 'alter database open';
    exit;
    </pre>
    x, y and z are placeholders for the filenumbers shown by the file# column of v$recover_file.
    Hope that helps!
    yours sincerely
