I have always gone the latter route when I needed it.  I usually use an action engine to keep track of the error messages.  Said action engine can be used to combine and suppress errors, as well.  I have posted an example below (LabVIEw 7.1).  In this case, the error propagation is occurring in a task handler which is processing multiple command/data pairs.  The command is set at the beginning of the task and the error handler is sprinkled liberally throughout the task code.  In this particular case, the desired behavior is to continue execution on error, but log the errors.
I prefer this type of method because it gives me complete control over the error propagation.  It has the down side of requiring more code and effort, but I think it is worth it. I like functionality to be explicit on my block diagrams.  It makes long-term maintenance much easier.

  • How to monitor the alerts(error handling) in seerburger adapter?

    hi,
    is it like normal moniotoring for any scenario..i have to do the monitoring in seeburger adapter.
    any other specific thing i have to take care to do monitoring the alerts (error handling) in seeburger adapter for AS2 and FTP adapters..
    plz give other ways to monitor interfaces for seeburger adapter.
    Regards
    Raja

    Hi Raja,
    All Seeburger adapters have option of some kind of acknowledgement to be sent to the sender or any  partner... u need to check the respective adapter documention....
    for eg: FTP adapter can be configured for Message protocol - FTP-REPORTS
    for sending various types of reports to any Business Partner,,,reports like dispatch report, transmission reports,,....etc
    and for monitoring errors in XI... u can configure alerts as u normally do.....

  • How to disable the LV error handler?

    I want to disable the LV error handler, im my application if an error happens i use a case structure to handle it.
    how can i do?

    Once you wire the error output of your function, automatic error handling is no longer relevant. That setting only matters for subVIs where you don't wire the error output.
    Just take the error output and wire it to the selector terminal of the case structure. You'll get an "error" and a "no error" case. Place appropriate code in each case so it act like you want it to.

  • How to add sound to the general error handler

    I'm looking for an easy way to create an audible indication (a beep or something) when the general error handler displays an error message.  Anyone have any suggestions??
    Solved!

    Hi Bill,
    I thought this was an interesting idea, so I wrote up the code and posted it on the NI Community here: Simple Error Handler with Beep.  If you have any cool VIs that you'd like to share, you can post them on the community as well to share them with others.  Thanks!

  • Using the general error handler on an embedded rt target

    I would like to know how the general error handler can be best employed
    with Labview RT on a Compact Fieldpoint controller.  Clearly no
    dialogue options are valid so how can error information be accessed
    remotely - is there an error log file available on the controller?

    I think there are plenty of ways to handle errors with Labview RT on a Fieldpoint controller.
    Usually I use the general error handler vi to catch the error and get the error message (sure, no dialog), then write the eroor message into a log file (ordinary text file created on the controller), and/or send the eroor message through TCP/IP network to the host. You can use FTP to open, read and tranfer the log file at host. Hope help.

  • How to use Request header in the OSB error handler

    Hi
    I have a scenario where OSB proxy service accptes the payload and routes to the target service
    and before routing, I'm generating UUId and inserting in to the request header and publishing the request payload along with UUID to another service.
    when the target service is thrown some business fault,i need to publish the fault along with the header(which has UUID).since my target service sends only fault body,header is getting emptied in the error hanlder section.
    How can I use the requestheader in the error handler section. Any help is highly appreciated.
    Thanks,
    N

    Just assign your request header ($header) to your variable (e.g. $myRequestHeader) and than use this variable in your error handler. Fault response will override your $header but can't override $myRequestHeader.

  • OSB Error propagation not propagating the original error

    Hi,
    I'm having trouble with understanding how to propagate error from inner to outer flow.
    This is the scenario:
    I have a flow listening on MQ queue, and in turn performs callouts to 3 inner flow's (protocol is local).
    Inside the inner flows there is no error handler, and all the handling is performed at the outer flow.
    The problem is that the error that is being caught is not the one I throw, instead I get a general BEA-380000 error.
    (when I put an error handler at the inner flow and print $fault I see the real error).
    Also I cannot put any "reply" operations inside any error handler because this will commit the XA transaction, and will prevent the message from going to backout queue - which I need to happen.
    How can I make the error propagate correctly?

    that's because the service error handler will wrap the fault in his own format
    so in each service error handler you need to recreate the soap fault with the error stack, and reply that back to the calling service, otherwise you will loose the error details already in the proxy service in which the fault occures.
    propagating the error without build the logic in each proxy service won't work if you ask me (and there also isn't a simple checkbox to enable anything on this)

  • Has anyone seen the below error before? Does anyone have any ideas on how to

    go about troubleshooting it? I am using a PCI-GPIB card on a WIN95 machine in an attempt to communicate with an
    ESP300 Universal Motion Controller ver 3.03. which reponds to ASCII commands.
    As a basic first step (using LabVIEW 6.0.2) I first attempted the example on p.20-6
    of the LabVIEW ver 6 Measurements Manual. I passed the string "*IDN?".
    I get the following error from the Simple Error Handler:
    Error -1073807339 occurred at VISA Write in esp300_scott1_mod4.vi
    Possible Reasons:
    VISA: (Hex 0xBFFF0015) Timeout expired before operation completed
    In a second attempt I tried using LabVIEW version 5 with the example on 8-12 of the
    User Manual, here I g
    et the same error from the Simple Error Handler:
    Error -1073807339 occurred at VISA Write in esp300_scott1_mod4_ver5.vi
    Possible Reasons:
    VISA: (Hex 0xBFFF0015) Timeout expired before operation completed
    N.B.--> I have successfully used NI's Measurement and Automation Wizard to communicate
    with the instrument. When I pass the string *IDN? I get the response:
    ESP300 Version 3.03

    Your best VISA troubleshooting utility is the VISA Interactive Control (nivisaic.exe). From this utility, you can use the VISA protocol to communicate with each of the VISA resources available on you system. If you are unable to get this utility to properly recognize or use your NI-GPIB card, It may be suggested to uninstall/reinstall the NI-VISA distribution. If you can get the utility to work then there is a programmatic problem which you must address. Debugging programmatic issues is best troubleshot using the VISAIC utility, NI-SPY (nispy.exe), and highlight execution. If you can outline a flow from within VISAIC, using NI-SPY you can log this flow and attempt to emulate it from within LabVIEW. Make sure each of the functions has the proper inputs. Also, try usin
    g some of the VISA/GPIB examples shipped with LabVIEW.

  • What does the "Copy error code files" option do in the build spec properties

    I have the "Copy error code files" checked for my application build specification but when I run my EXE on a different computer and call the simple error handler, I don't get the custom error from my computer's
    C:\Program Files(x86)\National Instruments\LabVIEW 2012\user.lib\errors\User-errors.txt file. Instead I get the "this error code is undefined" explaination.
    I've also tried including that file in the "always included" section of the build spec but that didn't work either. Am I missing something?

    Infinite,
    Check out this link:
    http://www.ni.com/white-paper/3209/en
    Specifically this paragraph:
    "When building an executable (EXE) or shared library (DLL) with the Application Builder, make sure to add the custom error file as a support file (under the Source Files tab). For an executable, the custom error file will be saved in the <executable destination directory>\user.lib\errors directory. For a shared library, the custom error file will be saved in the National Instruments\Shared\LabVIEW Run-Time\<version>\Errors directory. When distributing a shared library, make sure to install the custom error file in this directory."

  • Batch Updating error handling

    Hi,
    I have implemented batch updating in our application and it is working fine. I'm trying to find out if the following error handling procedure would be possible, and if so does anyone know how: -
    If executing a batch fails (determined from the int array returned), then identify the failing statement, remove it from the batch, log the failing statement, and retry executing the batch with the removed statement.
    Thanks in advance for any help you can provide.
    Chris.

    I believe you already have a list of failed items in the returned int array. There is no need to rerun the batch job. Those that can be updated were updated, those that cant be updated are indicated in the int array.
    Just report on which items in the array have zero for a value (failed to update). If your batch update is sorted (by the primary keys), then you know item 34 in the int array that failed is primary key xxxxxx. Therefore return not the int array, but an array of failed primary keys. As you build up your batch queries, store each primary key in an array so you can reference the int array to that primary key array.

  • Would it be possible to configure wi-fi airtime per day/week for my children. They have an iPhone/ipad device and trend to watch the screen every free moment of their time.....

    Good morning.

    Hello rogier111
    Maybe this helps:
    Open AirPort Utility, select your AirPort Base Station and click Manual Setup.
    Select Access Control Tab.
    Pick Timed Access from the list.
    Now click on the "+" button, enter the MAC adress of the device you want and decide for the network time limits.
    Update your Airport.
    You can find the MAC adress of an iOS device by going to Settings/General/About.

  • Since Yosemite upgrade, high pitch noise creating case vibration on MacBook Pro (15-inch, Mid 2009) (on watching the keynote online)

    Hi,
    Great work on Yosemite, great new design as well.
    Several problems since the Yosemite upgrade though :
        - When playing high pitch noise (watching the keynote for example), the speakers make the case around it vibrate. This was not happening under Mavericks and previous OSXs.
        - This page (post editing) does not allow the right click (works everywhere else as far as I'm aware).
        - when changing the volume, I have now the noise feedback when clicking on shift+volume up/down and no sound when clicking on volume up/down on my keyboard (was the inverse before).
        - The keyboard light was stuck in off, had to restart the computer.
    More general problems (covering the last OSX since introduction of 10.9) :
        - lack of possibility of choosing for a 3x3 set of desktops as it was before (the new mission control only allow us to have a horizontal set of several desktops)
        - Notifications cannot be turned off automatically when being in full screen. (only options for auto turn off given are "display is sleeping" oO and when "mirroring on another display" -> meh, would have prefer when having an app in full screen)
    System :
    MacBook Pro (15-inch, Mid 2009)
    Model Identifier: MacBookPro5,3
    Processor Name: Intel Core 2 Duo
    Processor Speed: 2.66 GHz
    Memory: 8 GB
    Bus Speed: 1.07 GHz
    Boot ROM Version: MBP53.00AC.B03
    SMC Version (system): 1.48f2

    Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

    Hello all,
    I have a 14.88G iPod Nano that I currently use as my primary watch. A week or so ago I started to experience a blank white screen when I press the "sleep/wake" button instead of the watch face (I have it set to wake from sleep to display the clock). When I hard reset it, it will come back fine and the screen will respond and work as normal, as soon as I manually put it to sleep by pressing the "sleep/wake" button and then try to wake it the same thing happens and I have a blank white screen that doesn't respond to touch gestures or anything.
    What I have tried so far to no avail:
    Numerous hard restarts (holding the "sleep/wake" button with the volume - button).
    Tried this: iPod nano (6th generation): Hardware troubleshooting
    Changed the watch face to display.
    Recharged the device overnight (without full discharge).
    Since none of this works I'm out of ideas. Eventhough I have a 6G Nano it should no longer be under warranty since I was sent it as a replacement for a different (older) product.
    Any ideas? Is this a known problem? Thanks in advance for any insight any of you could provide. Also, what time is it??
    Regards,

    Hey,
    I have the exact same problem as you have described. I also used my ipod as a watch but starting from today, whenever I unlock it the screen turns white until a reset is done. Even a factory reset through itunes didn't fix it.
    Have you found any solution?
    Bah, this is annoying.

  • Firstly I updated my ipad into ios7 and after watching the video by Apple, iWork, pages and numbers are free for download after updating iOS 7. How can I download iWork pages and number for free?

    Firstly I updated my ipad into ios7 and after watching the video by Apple, iWork, pages and numbers are free for download after updating iOS 7. How can I download iWork pages and number for free? Please help me.

    stevejobsfan is correct; iwork for ios is free only for new purchases of new ios devices. A good work around (if you have wifi connectivity) is going to the icloud website on your ipad, and working on your document.
    A word of caution (the real reason I am responding to your post). If you do a lot of 'formatting' of a document on iwork for mac, and then save it in icloud; you will probably loose most of the formatting you have done (this will be true if you oppen the document in iwork for ios; also) It happened to me, and I did not duplicate the document before saving it to icloud; I lost at least an hours worth of work.

  • HT1657 If I download a movie today, but will not be watching it for a few weeks (i.e. when overseas) - when does the 'activation' period start?  Do I have 48 hours from the download date or when I first watch the movie?

    If I download a movie today, but will not be watching it for a few weeks (i.e. when overseas) - when does the 'activation' period start?  Do I have 48 hours from the download date or when I first watch the movie?

    You have 30 days from when you download it, but when you then start watching it you have 48 hours (24 if your account is US based) to finish watching it before it expires.
