Maximum number of NI-CAN Objects

Hello Folks,
What is the maximum number of Ni-CAN objects supported by Ni - CAN boards ?
What is the maximum size of the write queue buffer supported by the boards ?
It seems there is a problem.
I am not able to open more than 32 CAN objects, with a write Queue length of 60 arbitration IDs
Note: I don´t what to use Frames !!!

I could be thinking of something else here, but it seems the maximum number of Objects is dependent on timing of the writing.
I think there needs to be a 2ms 'pause' between writes according to the CAN spec. So you could have 1 Object writing ever 2ms, 20 Objects writing every 10ms, 32 Objects every 16ms...
I couldn't find anything in the documentation to support this, so I may be totally off base.
On the ncConfigCANObj.vi, the Write Queue Length control has a maximum value of 1000 set in it's properties, so I would think that's the max write queue buffer.
Hope this helps.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

  • Is there a maximum number of "multi state objects" per article? Indesign keeps crashing

    Hi, i have 12 multi state objects on a page, and indesign keeps crashing.
    i know this seems like a high number, but I have done this to create a work around - ticker (like an old style airport board e.g. https://www.google.co.uk/search?q=airport+board&espv=2&biw=1306&bih=653&source=lnms&tbm=is ch&sa=X&ei=TkYUVb3ZJIb0PJ7DgZg… each set of 3 creating one graphic e.g. 3.35
    After creating these Indesign keeps crashing when i try to preview?
    Any advice would be appreciated.

    It sounds like you're running in to a memory problem: Memory Handling in DPS
    That said, usually multiple MSOs on the page don't usually cause memory problems because only the first state of the MSO is loaded into memory. If the first state of each MSO is loading a web overlay displaying ticker information, then that's the most likely culprit. Consider redesigning the page so that only a few tickers are loaded into memory and the user needs to tap to reveal additional tickers.

  • Maximum number of attributes can be added.

    hi,
    What is the maximum limit for which we can add attributes.? (display or navigational) (Is it 233?)
    What if I want to add more attributes exceeding the limiation? (One solutions would be to split the attributes. Is there any other solution? )
    please suggest me.
    thanks,
    Avneet

    Thanks for your quick response. Points awarded.
    Can you please tell me What if I want to add more than 248 characteristics in a single dimension without spliting them.
    I know that this would negatively impact on performance and mroe over, in general no report really would need so many characters.. But I am curious to know the anser.

    2. If so how to increase the no. of threads that can be created?
    3.Whether the No. of Threads can be created can vary based on the system configuration?
    Please
    ThanX in advance

    Hello there,
    I believe the previous answer is given correctly. There is no specific
    kernel limit to be set. You will eventually run out of virtual address space
    (after about ~3000 threads). Out of 4 GB virtual address space, kernel
    base address (ie., F0000000) and beyond is reserved for kernel (except
    for Ultra boxes where you can practically get almost 4GB each for
    kernel and process's virtual address spaces). Thus you have about
    3.75GB Sparc (3.5GB on X86 where the kernel base is E000000). It is
    not recommended to reduce the thread stack size (just be sure your new
    stack size will be able to handle the stack growth it needs per thread)
    but, if you are sure it is safe for your purpose, this can be done as an
    argument to a thread creation. Please see also manpage on thr_create.
    hope this helps.

  • Maximum number of Records for Emigall Upload

    Hi,
    Is there any limit or maximum number of records can be uploaded via Emigall at one time.
    Thanks.

    Hi Satish Kumar,
    There exists no limit except for some exceptions ;o) These exceptions are objects that require more and more memory during runtime due to growing internal tables. This behavior leads to performance issues because more and more time is spend in working on the internal tables instead of updating the database. This is known for the PARTNER migration object and all MM and PM related migration objects, such as, CONNOBJ, INST_MGMT, etc.
    On the other hand a long lasting import run (because it takes such a long time to migrate the objects in the import file) limits your options in controlling the data import, for example, restarting a cancelled import run. As already pointed out, the Distributed Import should be your choice when migrating huge import files with many objects to be migrated.
    I hope this answers your question.
    Kind regards,
    Fritz

  • How many number of pages can be included in a single spool request

    Hi ,
    How many maximum number of pages can be included in a single spool request. can we increase or decrease these max no of pages per spool in SAP.Please advise.
    Thanks & Regards,
    Sam.

    Hi Sam,
    The spool is ultimately a file created in the database. So it can handle a large number of pages.
    By defaut it shows only first ten pages.. This can be changed from the settings in SP01.

  • Maximum number of DatagramSockets

    I'm sending a DatagramPacket to 4000 different hosts, and I have successfully multi-threaded (50 threads) the process by having 50 DatagramSockets sending and recieving 50 DatagramPackets every 2 seconds.
    I'd like to up the number to 200 threads (meaning 200 sockets sending/receiving 200 packets every 2 seconds), do you guys think this is an issue? is there a limitation on the number of sockets I have active at a current time?
    Coles Notes: What is the maximum number of DatagramSockets can I run concurrently?
    thanks!
    -M

    how can I use 1 DatagramSocket for N hosts given that I'm multi-threading the operation?You can have multiple threads writing to the same socket. You can have a single thread reading from it and despatching messages to the session threads depending on where the incoming datagram came from.
    doesn't the the connect() method in the DatgramSocket class connect to only 1 host?Of course, but you don't have to call it at all. It doesn't do much.

    Hi,
    Maximum number of dimensions 16. Out of 16, 3 are system defined
    1.Datapacket
    2.Time
    3.Unit
    It is restricted to 16 because the maximum no of dimensions in any database is 16.

  • Maximum number of cores

    Hi,
    I am using solr4.0, i have created 10 cores in solr. I want to know how many maximum number of cores can be created in solr.

    As seens from the link already quoted, tthe number of allocated threads is dependent on the number of avaialble CPU cores. The parallel FOR loop can be set for up to 256 parallel instances with the following ini setting:
    ParallelLoop.MaxNumLoopInstances=256 (see here)
    If programmed correctly, LabVIEW can use all cores you throw at it. Of course if the code forces sequential execution due to poor architecture, extensive critical sections, and artificial data dependencies, the hands of the LabVIEW compier are tied.
    I have a Dual Xeon with 32 virtual cores (=16 hyperthreaded cores) and I can keep them all busy, gettting a 17x speedup over the single core performance (details). The code is highly optimized for parallel execution.
    If you need to do highly parallel matrix operations, you might also want to look into the MASM toolkit.

  • Maximum number of attachments for an e-mail

    Could anyone tell me what is the maximum number of attachments can be included in an e-mail? or size limit? Does the limitation imposed by mail server?
    Many thanks.

    The server might declare the maximum message size it accepts using the SMTP SIZE extension.
    You can query for the value using:
    ((SMTPTransport)transport).getExtensionParameter("SIZE")
    That's the total size of a message. Note that not all servers will return this information, even
    though they might enforce a limit.
    Computing the actual size of a message can be expensive.
    The simplest approach is something like this:
    CountingOutputStream cos = new CountingOutputStream();
    msg.writeTo(new CRLFOutputStream(cos));
    int size = cos.getSize();
    CRLFOutputStream is in the JavaMail download bundle in the demo directory.
    You have to write CountingOutputStream by subclassing OutputStream and counting the
    number of bytes written without doing anything with them.

  • Maximum number of accounts

    Have been using macs for twenty years but this one is driving me nuts.
    I have NEVER ever accessed iCloud on ANY device, though I probably tried in the past.
    Anyway, the other day I wanted to give it a try and I systematically get the message "you have reached the maximum number of accounts". So I can't login to iCloud.
    What I find pretty stupid is:
    - I am currently using ONE account that I wanted to use on ONE device
    - I can't create another account
    - I can't even manage my account to unactivate, for instance, the iPhone I'm not using anymore.
    So what the heck is this maximum number and how can we reset that?? This is nonsense!!
    Thanks
    Olivier

    Thanks.
    But I'm still lost.
    I'm pretty sure I didn't create three accounts on any device (as I said, I never ACCESSED iCloud before) and even if I did accidentaly, I don't remember which accounts they were.
    Ok, let's say I will start from scratch :
    - if I try to create a new id I get the message "this computer cannot create any more free account"
    So... I kind of understand there is a limit of a mix of devices and computers. But is there NO way to at least know what account is linked to what machine? I mean, let's say I DID create these accounts... how can I get a hand on them again??
    Thanks
