Can I just send the data to NIC's buffer in LV? (how to access data link layer?)

Now, I need to send something over network, yet those are not packed in TCP/IP or IPX packet, them are just some data a device can understand.
So the problem I met is seems I cann't send the data into NIC's buffer(I can do that in C, yet I want to use LabVIEW to do that)
And I don't want to do that by using a CIN, every time the program call or exit the CIN,there will be a delay, it's would bring me a bad impace to my application.
So is there anyone can help me with that? I really need some master can give me a comfirm!

I'm not an expert on network communication, so maybe you can explain how data can travel on an IP based network without being wrapped in some packets from a protocol like TCP or UDP? Maybe it's possible for LabVIEW to do what you want, or maybe compiling your C code into a DLL (no need for a CIN) and calling that will be fast enough for what you want.
In any case, I think I can answer one question:
So, how long would we have to expect LV add/improve these functions? Could it be in next minor update?
Not likely, nor is it likely to be in any other version soon. LabVIEW is not built to handle this sort of thing any more than PHP or perl are and I don't think NI will change it to be able to do so. For that you have C, which you can call through a DLL. Some DLLs are supported on RT targets as well, but I'm not sure what the criteria are. They are probably listed somewhere on this site.
I assume that calling a DLL in an RT target will hurt your determinism, but communication code should not be time-critical code, unless your application is an application which requires high speed data transfers and synchronization between different nodes.
Try to take over the world!

    how can I do that.

    The prior code produces a date formatted as Jul 7, 2004
    To get Wed 07, July 2004, try this minor modification:

    if i get an i pad with 3 g service capability do i have to use it in order for the i pad to work or can i just use  the wifi part because i dont have the extra money to pay for a data plan

    If you do get 3G, you only use cellular when wifi is not available. You pay by the month for a 3/4G plan.

  • Can we send the data into different data target from single datasource how

    Hai
    can we send the data into different data target from single datasource how ?

    Hi,
    Create the transformation for each target and connect through DTP if you are in BI 7.0
    If it is BW 3.5 create transfer rules and load it Info source and then different update rules for different targets then load it using IP.
    If you are speaking about loading data from R3 data source to multiple data sources in BI
    Then follow the below step.
    1)create init IP's and run the IP's with different selection to different DSO(With same selection it is not possible).
    2)Then you will have different delta queues for the same data source in RSA7
    3)Your delta loads will run fine to different data sources from same DS in R3.
    Hope this helps
    Regards,
    Venkatesh

    Best Regards

    Hello
    After conferring with a colleague, the following response may help:
    The Smart Form doesn't have any special integration in WebDynpro.
    Therefore the application should implement it especially.
    Steps:
    1) Call of Smart Forms in mode GET_OTF
    2) Convert OTF to PDF
         3) Show the PDF in WD Context Node

  • I keep getting an error stating that my disk is full in syslog. The file is empty and I want to stop it from logging data. Can I just delete the file?

    Can I just delete the syslog file?

    Hello,
    Yes, you can delete the file. A new file in Syslog directory is started each time that LabVIEW and the Tag Engine is started. You can either manually delete old files or write a simple VI to automatically delete files that are older than a certain number of days.
    As an alternative, you can save these files into another folder, just to free up syslog directory space, and still have these history files for later use.

  • How to just send I data (No Q) using ni2920 USRP? (ASK modulation)

    Hi.  
     I am trying to send three level sequences as amplitude shift keying (ASK) modulation. my sequence has three state of (-1, 0 , 1). I am using ni2920 usrp to send carrier with amplitudes of -5v, zero, and +5v for each of the mentioned levels respectively (ASK) (Sample rate=25 or 50MS/s). to do that,  I saved a .txt file with voltages amplitudes in the PC and I am reading this .txt file and send them with USRP (I expect USRP to multiply these values with cos(carrier freq) and send it to its RF out port. However there some problems:
    1. I am not sure about the order of data USRP expects to have when reading .txt file in terms of "I" and "Q".  Assume I am sending  0,0,-1,1,1,-1,0,... I have a txt file with 0,0,-5,5,5,-5,0 saved .. BUT every time my code reads this txt file , it assign a vector of <"I","Q"> pair at output of LAN cable instead of considering all numbers as "I" data. my problem is: How can I force USRP to just send I data (no "Q") ? (This is required since I am using ASK modulation)
    2. when I read zero from txt file and send it, I expect to see zero level RF spectrum at output BUT according to my observation there is spectrum content of output RF when sending all zero sequences. How can I force USRP to send nothing (zero) when the bit=0? 
    Any help is appreciated. Thanks.

    1) You can send data to the device as complex double-precision data or binary I16 data.  If using the complex double type, just make the imaginary component of each complex sample 0 (Q is the imaginary componnent).  If using the binary I16 data, the samples are interleaved I, Q, I, Q, ... so just make every other sample 0.
    2) Even when sending 0s for I and Q, if the device is tuned to a frequency and the output path is enabled, you may see some power at the carrier frequency that is basically leakage from the local oscillator.

  • I just pressed the wrong button to erase of my IMac, how can I get back all information from my computer ?

    I just pressed the wrong button to erase of my iMac, how can i get back all information ?

    Possibly through a data rescue service (can cost a four-figure amount) if you didn't have an external backup.
    But you must stop using that Mac immediately, or your data will be over-written.

  • Race conditions - can you actually lose the data in memory?

    I've seen posts where a race condition can actually destroy the contents of a global memory. I understand about not getting the right information if your read just beats your write, but can it actually lose the data altogether? This would mean you have to semaphore every time you write to a global if you have something polling on it to guarantee the data doesn't get lost. I've never seen this in any example programs - its hard to believe!

    I think the idea is merely that when you write to a global (or any)
    variable the previous contents are overwritten. If you intended to read the
    global before the write but the write ends up happening first then you lose.

  • Error while sending the data using input schedule

    Dear Friends,
    I am unable to send the data using input schedule due to following error is occur while sending the data.
    The Error Message : Member (H1) of dimension (ENTITY) is not a base member (parent or formula)
    Can anyone please help me to resolve the above error.
    Thanks and regards,
    MD.

    Hi,
    You are trying to send data to a parent/node, you can only send data in BPC to lowest-level children (base mamabers) of any dimension.
    "H1" is a parent in the entity dimension so you should try sending to a child.

    My videos from my iphone are horrible when I transfer them to my PC. How can I improve the video on my PC? Can I just convert the files to WMV? When the video plays the speed is off, it's half slow-motion and staggers into normal play. The clips are slightly cut as well, the clips do not roll continuously.  I'm taling about videos that are no more than 2 minutes long.  I'm frustrated and I could really use some advice-my kids basketball games is what I'm recording and I'm trying to send them to my family (they are not very tech savvy).

  • How to send the data manually

    Hi Experts,
      I need small information.when messages are gone into queue state due to one message 
    When an EDI file came into wrong format and with that some messages are gone into queue state in MONI.
    if i cancel the first message then remaining all the messages are processing successfully.
    So from that cancel message i want sent the data manually as business needs that data.
    Can all please tell  me how to send the data manually with steps.
    Thanks in Advance.

    Hi,
    I think you are talking about QoS "EOIO", in which all messages are porcessed in FIFO order and whenever the preceeding message get stuck due to error in the queue, then all the messages are stoped. And yes as soon as you will cancel the message which went into error all the remaining messages will automatically will be delivered.
    In my opinion since QoS is EOIO then it will be not possible to sent the data mannually, you can do one thing, do not cancel the message. Try to correct the messge and then resend it.
