Error message when using counter indicating need to use faster timebase

I'm attempting to use the two onboard counter timers on my DaqPad 6015 with a SC2345 carrier.
The program initially runs as expected, but once in a while I get an error message that reads as follows:
"2 consecutive active edges of the input signal occured without a counter timebase edge."
"Use a faster counter timebase"
I have only attempted to read this signal at two known frequencies: 15 and 20 Hz.
Can anyone advise as how to correct this or how to change the counter timebase?
I'm using the built in Express Daq Assistant to create the code to read the frequency so that part is pretty straight forward.
This command is however inside of a case structure, so each time it reads it is possible to reset or miss the first leading edge of the signal.
Thanks,
Patrick

Hi Patrick,
It sounds like the program is lagging when you attempt to read the gate of this counter. 15 Hz seems slow in comparison to the specs of the counter, but if your VI is slow by 7/100th of a second the program will thrown an error. I recommend probing the counters to determine where in the program the error occurs.

  • I get this error message when I try to email photos using iPhoto: Your email did not go through because the server did not reply.

    I get this error message when I try to email photos using iPhoto: Your email did not go through because the server did not reply. How can I get this to work when my internet is connected?

    Are you able to email from Mail with those two accounts?  If so:
    1 - go to iPhoto's Accounts preference pane and delete both accounts. Now add them back and try again.
    2 - a better solution IMO is to set Mail as the email client for iPhoto is iPhoto's General preference pane.  This gives you better access to your contacts, a sent copy of all emails and, if you want a layout similar to iPhoto's, photo layouts located in Mail's stationary.

  • Error Message When Leaving Review For Apps Downloaded Using a Different Country App Store

    DEVICES AND SOFTWARE:
    iPhone 6 Plus iOS 8.1.2, Macbook Air 11" 2013 OSX 10.10.2, iTunes 12.1.0.50
    DESCRIPTION:
    When attempting to leave a review for an App that has been previously downloaded or purchased using a different country store but on the same Apple ID - the user receives an error message. The issue stems from the App not being in the Purchase History of the presently associated country store as purchase history is country dependent rather than Apple ID dependent.
    STEPS:
    1. Login the App Store on iTunes or iOS Device using an Apple ID associated with a country.
    2. Download an App for the first time using said Apple ID.
    3. Change the country of said Apple ID.
    4. Attempt to leave a review of the previously downloaded app.
    EXPECTED RESULTS:
    A user should be able to leave a review to an App he/she has previously downloaded whilst the Apple ID is associated with a different country. The App Store button should show Downloaded after the country change and the App should continue to be displayed in the Purchase history. In other words the purchase history should not be country dependent but Apple ID dependent.
    ACTUAL RESULTS:
    User gets an error message indicating that the app needs to be downloaded or purchased first.
    NOTES:
    I have tried deleting my reviews from the original country store, and yet I am still not able to leave a review. Please make the purchase history dependent on the Apple ID rather than the Country Store. If this is not possible, provide a way for users to remove to delete the purchase history from the previous country store(s) - so these apps can appear on their current country store's purchase history. Thus they would be able to leave reviews for these apps.

  • Error message when trying to view a table using SM30

    I'm getting the following syntax message for all tables in a function group:
    "BSPC_DL_XMLSTRX2" must be a flat structure. You cannot use internal tables, strings, references, or structures as components. -
    I believe this was generated through the easy enhancement workbench.  It won't let me modify the structure using the Table Maintenance Generator in SE11.  How can I get this object removed from this function group? 
    thanks.

    Hi
    Common issues for this :
    1. Once you install crystall add on ,you need to go to Crystal report Administration >Account setup .
    Put on the user name and password and click on creating ext tables
    Try then running the report .
    If not the case ,
    make sure you install runtime .
    You need :
    1.Crystal report basic from SAP download -(Not necessary if you want only report viewer >
    2.You need to have crystal integration addon (I think service pack is SP1)
    3.Make sure you have runtime install
    When you are installing ,make sure you restart your PC before you do or remove temporary file s
    Hope this solves your issue

  • Error Message When Using a Class Files to Control Navigation

    This is my first attempt at using a class file in a flash project. My intent is to keep all of my navigation elements in class file called "Navigation".  However, I keep getting an error message when I publish.
    I am using a button to go back to the main screen and I gave that button the instance name of "bnt_home". I have also linked that button in the library to the class "Navigation".
    Here is the code:
    package
        import flash.display.SimpleButton;
        public class Navigation extends SimpleButton
            public function Navigation()
                bnt_home.addEventListener(MouseEvent.MOUSE_DOWN, goNavigation);
            private function goNavigation(event:MouseEvent):void
                gotoAndPlay(1,"Main");

    When I changed the code I got error (1046: Type was not found or was not a compile-time constant: MouseEvent).
    package
        import flash.display.SimpleButton;

  • Error message when saving .fm file

    I just upgraded my FrameMaker program to 7.2.
    When I try to save my work, the following message appears on-screen:
    An internal error occurred while writing imported graphics in this document.  The file has been saved, but has lost some image data.  Please report this error to Adobe Technical Support.
    My file has NOT been saved, none of the changes I've made have been saved.  I cannot save this file under a different name, either.  And the automated files that are generated by the program as "back-up" files are useless.
    HELP!!!

    Upgraded to 7.2..... Good that you didn't rush into it. ;-  )
    Anyway, that's the standard error message when a file contains objects imported using an OLE link AND you are running XP SP3.
    SP3 implemented security fixes that essentially broke OLE within Frame (and a number of other applications).
    So if your document(s) contain OLE links, you're likely to have to convert them to imported-by-reference graphics if they're graphic files or do some other type of conversion if they're tables or PPT slides.

  • Error message when using Spry Data set with XML

    Hi,
    I have what i see as a big problem, might just be me being
    dumm, but here we go.
    When I try to use the feature of spry XML Data Set and insert
    spry table I get error message when trying it in IE 7.
    There are even a problem when I use fireworks automated slide
    show function, where you can choose to use the Spry/XML gallery
    feature.
    The error message I get everytime (incl the auto gallery in
    fireworks) is:
    The tag: "html" doesn't have an attribute: "xmlns:spry" in
    currently active versions.[XHTML 1.0 transitional]
    The tag: "div" doesn't have an attribute: "spry:region" in
    currently active versions.[XHTML 1.0 transitional]
    The tag: "th" doesn't have an attribute: "spry:sort" in
    currently active versions.[XHTML 1.0 transitional]
    and so on.
    What´s wrong?!

    Hello barvid,
    Ok, let's take each problem step by step:
    1. The first error you see in the browser: " Exception while
    loading ..." normally appears when you try to load files that are
    not permitted by the browser security model. This means the XML
    file you try to load is located on a different server than your
    HTML which is not allowed. The browser is not permitting to load
    any files that are not in the same domain as the current page
    because of the complex security risks. You'll have to either get
    the XML file from its original location and save it in your website
    or use a proxy on your web server that should request that file
    from the external server and send it to the browser as an XML from
    the same domain as the HTML origin.
    1.2 The "Exception while loading ..." error you see is a
    generic error and my previous advise is based on my experience. In
    case this is not your scenario you'll have to open the SpryData.js
    and around line 112 you'll see the following code:
    Spry.Debug.reportError("Exception caught while loading " +
    url + ": " + e);
    Please change this line with the following line of code:
    Spry.Debug.reportError("Exception caught while loading " +
    url + ": " + (e.message?e.message:e));
    to obtain a more verbose error message that may clarify the
    reasons of your errors.
    2. The problems you describe are not browser errors but they
    are w3c validation errors. At this point the XHTML standard allows
    every application that define custom namespace attributes to also
    link a DTD to the page so the page to continue to be valid.
    Unfortunately at this point this feature is not correctly supported
    by the FF and IE so we wrote an articles about how you should
    link
    the Spry DTD to your page so the validator understand the
    custom attributes Spry use. You'll find inside the full description
    of the problems and all the technical details you'll need to know
    to solve this issue.
    Regards,
    Cristian

    Reboot the TC.. Sometimes you need to reboot the whole network.
    This is what comes of Lion and then made worse in Mountain Lion of Apple not spending enough time to fix the bugs.

    Thanks Jon. I tried all of those solutions before posting. Same problem. It seems that the problem is tied to DWCC. Do not have the problem when using DW6 on Win8.1. When running DWCC on a Win7 pc, we get the same error message. When running DW6 on Win 7, f&c works fine. It seems to be a bug in DWCC. DWCC works flawlessly on our Macs.
    The same steps apply to DWCC, you just need to choose the CC folders rather than the DWCS4-6 versions that the page talks about. The layout of CC's folders hasn't changed from the older versions which is why, I think, Adobe hasn't updated the troubleshooting page as of yet.
    As Nancy mentions, a 38,500 page site is sort of ridiculously large for a static website, that could be part of the problem, but your response quoted above leads me to think you may have tried the troubleshooting steps in the wrong version of the program. Could you confirm that?
