Problem with data acquisition and motion control

I have PCI-6024E and PCI-7342 cards on a single PC. Servo motion control works fine when it goes alone or is accompanied by one point data acquisition in a while loop, but when I start data acquisition with specified sample rate, the motor moves with breaks.
Does anybody know what is the problem? Is it possible to fix it?

How are you performing your motion? Is it a position move or a velocity move? How are your triggering the data acquisition? Using breakpoints on the 7342? If so, are you using single breakpoints or modulo? How are you configuring the data acquisition rate? Are you triggering just the start to the acquisition and the unsing the daq scan clock or are you using the motion controller to send the scan clock itself?

  • A problem with data acquisitioning in LV 7.1 (transition from Traditional NI-DAQ to NI-DAQmx)

    Hi to everyone,
    I have a problem with data acquisitioning in LV 7.1.
    I made a transition from Tradiotional NI-DAQ to NI-DAQmx in my LabVIEW application.
    The problem I have is that when I acquire data in Traditional (without writing somewhere -
    just reading) then there is no scan backlog data. But when I acquire data in application that
    acquisition is based on DAQmx than a scan backlog indicator shows numbers from 20 to 50 for
    about 6 min and then that number quite quickly increases until I get an error (unable to
    acquire data. The data was overwritten).
    Acquisition settings are the same in both cases. When I acquire with DAQmx I use a global
    channels. Is a reason for that phenomenon in global channels data procesing? But it seems
    strange why does it flows quite smoothly for about 6 min and then it stucks?
    Best regards,
    Ero

    If you have an old Daq unit it may not be compatible with DAQMX. Which DAQ unit do you have? I think NI have a list showing which DAQ driver you can use with your card
    Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
    (Sorry no Labview "brag list" so far)

    I know it is something to do with data formats and the fact that I do not fully understand the use of wwv_flow_item.date_popup().

    Hi DK,
    It is a WD Java application, Backend is ABAP (MM module).
    The UI is input field, where the context attribute type is Date, So its been changed to Date Picker.
    The problem is when the user runs the WD application in Portal, The calendar format is being changed for some users. That is for few users the Week starts with Monday and for few users the week starts with Sunday.
    I need all the users to have Monday as the First day of the week.
    Please let me know, what will be solution for this.
    Since I haven't done anything in regard to date, it is a simple Date format.
    Thanks & Regards,
    Palani

  • Problem with Data Model and Analysis View

    I create an analyze in BI Publisher and then i create a data model using this object.
    When i try to generate an XML with a number of rows the BI Publisher return an empty XML (Only with de DATA_DS tags but no data).   To bypass this problem i make and XML file by hand and this allow me to create reports and design it but when i try to view the reports i got the message that says "No Data Found".
    So i was check the analysis and all looks appears to be fine,  In the results tab it show me a complete table with the data i was looking to use.
    So i try to repeat the error and when  i try to create the XML for the Data Model i found this two error in the logs:

    As i understand there is has a reference to a null value but i cant find what column of the analysis has the problem.
    Any ideas about how to solve or debug this?
    Thanks

    I follow your instructions and it works fine. I can create the XML and the reports can show data.
    So, i already know that there is no problem with the data and with the BI Publisher installation but i still doesn know what is the problem with the analysis view that fails.
    Any idea how to debug it?
    Thanks.

    Hello,
    I have replicated and confirmed the problem with LabVIEW 2010, Report Generation Toolkit 2010 and Word 2010.  I have filed this to R&D under CAR ID #257414.  As a workaround you can manually set each cell using Word Edit Cell.vi.  I have attached a simplified representation of this unexpected behavior as well as the workaround.  Hopefully this helps everyone out!

  • Help: Problem with data types and classes

    Hi there,
    I'm currently struggling with getting a class to read in data from a file and from that select the correct constructor to use... Basically I read a line in from a file as follows:
    <String Make>:<String model>:<String registrationNumber>:<String engineSize>
    e.g.
    Ford:Focus:HG42EG:1800
    There is an Interface called Car, of which 'Ford' is an implementation along with 'Vauxhall', 'Chrysler', etc...
    From this I wish to construct a new instance of a Ford called Focus with input parameters (RegNumber registration,int engineSize) i.e.
    Car Focus = new Ford(HG4 2EG,1800);So far I can convert the engineSize String into an integer and can construct the RegNumber (a class of mine) but can only get it to construct a Ford by using a switch, i.e:
    switch (modelKey){
    case 'f': new Ford(); break;
    case 'v': new Vauxhall(); break;
    case 't': new Toyota(); break;
    etc...
    Now I do get this to work correctly but I'm concerned that it is not OOP therefore is the way I can get code to convert the String 'Ford' into Car 'Ford'.???
    Many thanks in advance for any advice you can throw my way,
    Leebo

    What is this anyway???
    If Car is an interface you can't create instances of it....No, if Car is an interface, his code should be (depending on what the RegNum constructor looks like:
    Car Focus = new Ford(new RegNum("HG42EG"),1800);It's the same as:
    List someList = new ArrayList();However, he won't be able to use a word read from the file as a variable name "Focus". He'll need a Map:
    Map myCarMap = new HashMap();
    myCarMap.put("Focus", new Ford(new RegNum("HG42EG"), 1800));(Could be defined as "Map<String, Car>" if he wants to use generics.)

  • URGENT ! JDEV 10.1.2 Problem with data control generated from session bean

    I got a problem with data control generated from session bean which return a collection of data transfer object.
    The dto's seem to be correct. The session bean load correctly the data into and the object's are plenty of data. Using the console to display the dto content is ok.
    When generating a data control from this session bean and associate the dto included in the collection only the first object level and one-to-one dto object are correctly setted in the data control. Object that represent collection into the dto (one-to-many foreign key) are setted as collection with an iterator but the structure of the object is not setted. I don't know how to associate this second level of collection with the dto bean class to obtain the attributes definition.
    I created a case with hr schema like the hrApp demo application in the tutorial with departments and employees table. I got the same problem.
    Is it a bug ?
    It exists a workaround to force the data control to understand the collection data structure ?
    Help is welcome ! this is urgent !!!

    we found the problem by assigning the child dto bean class to the node representing the iterator in the xml file corresponding to the master dto.

    having a problem with dates when I send my numbers doc to excel. dates are all out and that they have to cut and paste individual entries onto their spreadsheet. Any idea how I can prevent this.
    I'm using Lion on an MBP and Numbers is the latest version

    May you give more details about what is wrong with your dates ?
    M…oSoft products aren't allowed on my machines but I use LibreOffice which is a clone of Office.
    When I export from Numbers to Excel and open the result with LibreOffice, the dates are correctly treated.
    To be precise, dates after 01/01/1904 are correctly treated. dates before 01/01/1904 are exported as strings but, as it's flagged during the export process, it's not surprising.

    fair enough.  No need for any unnecessary posts either.  You issue had been addressed ad nauseum already in this forum had you bothered to search this forum (as forum etiquette would dictate) before posting.
    In any case, I hope that your problem was solved.

  • Does anyone have problems with data usage with att and Iphone5?

    Hello, Does anyone have problems with data usage or non usage I should say with Iphone 5 and AT&T?

    After 4+ months of dealing with this data usage and battery drain problem that included 3 data captures of my wife's iMac, the trigger for us regarding the problems syncing with iCloud, and 5 hours of logs off my iPhone 6 to be analyzed by Apple engineers that included times my wife's computer was both on and off to demonstrate the difference in data usage and battery drain under those conditions, I can say with very reasonable certainty that the iOS 8.3 and corresponding Mac OS 10.10.3 update has solved the problem. 
    We have now been running for about 2 weeks and data usage with the iCloud Servers attempting to sync has dropped from a rate of 31 GBs to under 15 MBs per month.  Yes, you read it right.  We were burning 2000 times as much data doing absolutely nothing important on both of our phones, a 5s and a 6.  Just imagine what that does to battery life!  The 5s would last about 5 hours and the 6 was dead in less than 14.
    The distasteful aspect of this process was how the engineers were quietly fixing the problem at the same time sending messages to my contact person within Apple that were dismissive in nature in the face of indisputable unreasonable results. I must say, this experience with the multiple times the engineers' responses were inappropriate put a little tarnish on the old Apple shine of the ‘It just works’ mantra. This was my first experience in 34 years that caused me to stop recommending Apple products without reservations and with a disclaimer.
    Since the update solved the problem, then I can only conclude that there was a logic bug regarding the reaction within the process to the incoming data that was corrected.  There was noting short of logging out of iCloud that circumvented the problem for us, Gator5000e and probably many others noted on other threads.  I am not trying to imply that this is the cause of everyones battery use problem, but it is reasonable that it was a cause for many.

    under this category my questions fit better.
    I have a problem with the MenuBar and a question to delete a
    component out of storage.
    1. We have implemented the MenuBar, which was filled
    dynamically with XML data.
    Sporadically it will appear following fault, if we "mousover"
    the root layer.
    RangeError: Error #2006: Der angegebene Index liegt
    außerhalb des zulässigen Bereichs.
    at flash.display::DisplayObjectContainer/addChildAt()
    at mx.managers::SystemManager/
    http://www.adobe.com/2006/flex/mx/internal::rawChildren_addChildAt()
    at mx.managers::SystemManager/addChild()
    at mx.managers::PopUpManager$/addPopUp()
    at mx.controls::Menu/show()
    at mx.controls::MenuBar/::showMenu()
    at mx.controls::MenuBar/::mouseOverHandler()
    Here a abrid ged version of our XML to create the MenuBar:
    <Menuebar>
    <menu label="Artikel">
    <menu label="Artikel anlegen" data="new_article" />
    <menu label="Artikel bearbeiten" data="edit_article" />
    <menu label="Verpackung">
    <menu label="Verpackung anlegen" data="new_package" />
    <menu label="Verpackung bearbeiten" data="edit_package"
    />
    </menu>
    <menu label="Materialgruppe">
    <menu label="Materialgruppe anlegen"
    data="new_materialgroup" />
    <menu label="Materialgruppe bearbeiten"
    data="edit_materialgroup" />
    </menu>
    </menu>
    </Menuebar>
    It is a well-formed XML.
    2. Delete a component out of storage
    We have some own components (basically forms), which will be
    created and shown by an construct e.g.
    var myComponent : T_Component = new T_Component ;
    this.addChild(myComponent)
    Some of our forms will be created in an popup. On every call
    of the popup, we lost 5 mb or more, all childs on the windows will
    be removed by formname.removeAllChild();
    What cann we do, that the garbage collector will dispose this
    objects.
    Is there a way to show all objects with references (NOT
    NULL)?
    I have read in the Flex Help, that
    this.removeChild(myComponent) not delete the form and/or object out
    of the storage.
    Rather the object must be destroyed.
    It is sufficient to call delete(myComponent) about remove
    this object out of the storage as the case may be that the
    garbage-collector remove this object at any time?
    Or how can I destroy a component correctly. What happens with
    the widgets on this component e.g. input fields or datagrids?
    Are they also being deleted?
    Thanks for your help.

    If you mena the "photo Library" then you cannot delete it.
    This is how iphone handles photos.  There are not two copies.  There a re simply two places from which to access the same photos.  ALL photos synced to iphone can be accessed via Photo Library.  Those same pics can be accessed via their individual folder.

  • Driver missing - PCIe Data Acquisition and Signal .....

    Hello, i recently used Boot Camp to install Windows XP on my 2010 15" Macbook Pro.
    All the drivers are working (so far) and i haven't encountered many problems.
    However, there is one thing bugging me:
    When i go into Device Manager in Windows, and look down the list of installed/uninstalled devices, there is a device called "PCIe Data Acquisition and Signal Processing Controller" which has no driver installed.
    I'm PC savvy, but i have never seen this before. My guess is that one of the motherboard drivers is missing, and Boot Camp installer doesn't include that driver?
    Has anyone seen/resolved this, and if so, how?
    Thanks.
    Kaj.

    Okay, will do.
    Thanks.
    Also i wonder if you could help with another problem?

  • E5-571 PCI Data Acquisition and Signal Processing Controller & SM Bus Controller

    I upgraded from Windows 8.1 to Windows 10. Windows Update says that it is up-to-date. Windows Devices Manager shows a problem with two devices: PCI Data Acquisition and Signal Processing ControllerSM Bus Controller What are these devices and where do I locate the drivers for them?

    That should do it. I've been pleasantly surprised by how well older drivers are working in Windows 10. I had to install Vista 64bit drivers for an ATI video card (the latest working drivers for the card) and they actually worked!
