Read all raw data out of the CAN bus

Hello,
our company has purchased a complete CAN bus HW; chasis 9174 and module 9862. I am using NI-DAQmx 9.5.5, NI-XNET 1.5.
I have connected the module (CAN High, CAN Low, Vsupp 12V - Car battery, GND - Car battery) to the ABS CAN bus segment.
Using Osciloscope on CAN High and CAN Low wires I can see communication rolling when I start the car ignition.
I had no success using the Bus Monitor utility.
I made a very simple read VI hoping to monitor some traffic.
All VIs run without error, but the Read VI is returning same data (Ignition off or on), I do not know what am I supposed to recieve, what kind of data is the output.
I think it is wrong, since I get the same data out of it no matter what the CAN bus traffic is.
The array of frames is filled with two frames with message identifiers that should be transmitted. I added two frames into emopty database and no signals.
1) From my understanding, the Bus Monitor utility monitors only those messages that I specify in the database, so that no messages/frames = no traffic monitored, is this correct ?
2) Is there any way, how to read all raw data from the bus ? What VI palettes to use... ?

Problem solved, the company that was preparing the car made wrong labels (swapped CAN H with CAN L)

  • How to delete the raw-data out of the meta data (file information)

    Hi guys,
    I am definetely going crazy: since half an hour I can´t find a solution than copy (image) paste and save as a virgin jpeg: I`ve just converted some 0,5 GB tif files which I elaborated heavily in ACR and the 550 by 367 PIXEL JPEG @ quality 9 has 1,1 MB. As all your moves are saved in the raw-data (last field inthe fileinformation) there´s quite a bit on the file, also on 3 by 2 Pixel (!) "big" derivates. It seem´s there´s no intellegent way to discard this information. If you know, please let me know!
    Thanks, Sebastian

    You could try the following code to remove all the metadata, run it from within ExtendScript Toolkit and select the files in Bridge.
    #target bridge
    removeXMPData();
    function removeXMPData(){
    if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
    var sels = app.document.selections;
    for (var a in sels){
    var thumb = new  Thumbnail(app.document.selections[a]);
    var md = thumb.synchronousMetadata;
    var xmp = new XMPMeta(md.serialize());
            try{
            XMPUtils.removeProperties(xmp, "", "", XMPConst.REMOVE_ALL_PROPERTIES);
            var updatedPacket = xmp.serialize(XMPConst.SERIALIZE_OMIT_PACKET_WRAPPER | XMPConst.SERIALIZE_USE_COMPACT_FORMAT);
            thumb.metadata = new Metadata(updatedPacket);
            }catch(e){alert(e);}

  • I've recently messed up my Mac OS X Lion by deleting Aperture, but I need to get my data out of the computer. And by the way, I've got an important project in Final Cut Pro X. Is there any way I can back it up (including fxs and positions of the clip) ?

    Hello everyone
    I've recently messed up my Mac OS X Lion by deleting Aperture, but I need to get my data out of the computer. I've tried to repair it using DU, but it said I needed to backup all my data and reinstall the OS. How do I backup my data to an external drive?
    And by the way, I've got an important project in Final Cut Pro X. Is there any way I can back it up (including fxs and positions of the clip) ?
    Hope you guys can help me!

    You need to back up 2 folders, Final Cut Events and Final Cut Projects which by default are located on your Movies Folder. You can always check by clicking on a clip inside Fianl Cut X and selecting Show in Finder in the contextual menu for the selected clip.

    Favor the route via iTunes and local storage on the computer. MUCH faster than any cloudy backup, no matter the speed of your Internet connection. No network beats the speed of a hard drive. Just make sure there's enough room on the computer before you start, must contain all that's on the iGadget.

  • I just plugged in my Iphone after 4 weeks of downloading music and adding contacts around 400 to be excact and it whipped all my data out and I have no photos nothing reset to factory defult and I cannot even listen to music I purchased because it skips

    I just plugged in my Iphone after 4 weeks of downloading music and adding contacts around 400 to be excact. When I plugged it in my computer it started to sync with iTunes and it whipped all my data out. I have no photos contacts nothing, so I then in a rage reset to factory defult and I cannot even listen to music I purchased because it skips. I just want my phone back

    Was this the very first time you ever plugged the phone into that computer?
    Did you pay attention to the prompts you were given when you plugged it in?
    Did you have iCloud backups turned on before you did this?  I hope so... If you did, restore the phone from the last iCloud backup from before you wiped it. If not, then the photos, etc. are gone. Apps and music can be re-downloaded.

    YEA!  My jurryrig worked!  To all with this problem:
    You CAN have podcasts in a regular playlist IF you convert them to a standard MP3 first.  So, yes, a lot of manual labor
    The good news: if, like me, it is a track that you listen to frequently (in my case meditations for sleep and relaxation) then the time is worth it.  I will mess with automator later to see if there is anyway to script this!  Then, less work for me and more for my mac.
    Here are the steps:
    Select the file from your Podcast folder.
    Change all data you need -- "artist," "album" etc...
    Make a copy of the cover art for this file by dragging it to the desktop.
    Select the Advanced -> Convert ID3 Tags menu item.
    Check ID3 tag version, and select "v1.0" from the drop-down menu.
    Drag the file to the desktop (this will make a copy of the MP3 on the desktop)
    Delete the file from the iTunes list.
    Drag the copy of the file you have on the Desktop back into iTunes.
    Search for the file in the Library, and add the cover art again to the file.
    Now the file is out of the Podcasts folder and works like a regular MP3 file inside iTunes. You can re-add it back to playlists!

    I lost all my data while doing the latest software upgrade, how do I get it back if I dont have a backup on iTunes?

    If you don't have a backup, then all your pics/text/notes are gone.
    You can sync back music and app.  If you were syncing your contacts with a program in itunes, then you'll get that back.
    Not sure why you didn't do a backup, especially prior to doing an upgrade.

  • Can we monitor the CAN bus load through a vi

    Is there a way to monitor the CAN bus load through a vi? I am using USB 8473 to establish a CAN communication.
    Thank You,
    -Raghu

    Hi Raghu,
    Are you referring to fuctionality similar to the percentage bus load the NI CAN Bus Monitor shows?
    If so, there are no built-in LabVIEW VIs that access this information.  You would have to use the available CAN VIs and implement it yourself. 
    Alternativly, if you only need this for testing, you can use another NI CAN device on the bus to monitor the bus load and then simply remove this device for deployment.
    Hope this helps!

  • Is it possible to programmatically start the CAN Bus Monitor?

    Is it possible to programmatically start the CAN Bus Monitor?  I was unable to find the executable, so either I'm not looking in the right place or it's built into NI-CAN or MAX.

    Indeed it is.  I found the executable at c:\Program Files\National Instruments\NI-CAN\bin.  It won't run by simply clicking on it, you must call it with the can port (e.g. CAN0) as the first paramenter.

  • I can record midi data from my Mason & Hamlin Piano Disc Pro Record through my MOTU Traveller into Logic but Logic won't send midi data out to the MOTU Traveller to the Piano Disc player

    Hello All,
    I can record midi data from my Mason & Hamlin Piano Disc Pro Record through my MOTU Traveller into Logic Pro 9.1.8  but Logic won't send the midi data back out to the MOTU Traveller and thus to the Piano Disc player. I got it to playback one time but have no idea how and when it did it was looping or something because the velocity was way high coming back in and the damper pedal was slamming down. When I play a key on the piano the midi "in" light on the Traveller lights up. When I play the track back on my computer no lights blink on the Traveller and when I did the apple midi studio test in utilities when I play a key I get the confirmation signal noise and the Traveller blinks when I click on the down arrow of the Traveller in the Apple midi studio test the midi out light on the traveller never lights and the signal light on the piano does not blink either. No outbound signal at all...
    I have messed with every possible parameter I can find and and have had help from one of Piano Disc's premier editors but no luck. The piano was prepped for me on Logic so it would work with my studio.  I'm positive it's my fault and I'm overlooking something really simple and stupid but what!??!
    Somebody please help.  Thank you all in advance for ANY ideas you might have!

    Blues Piano,
    I'm not sure if this will be a help or not.  I'm so Logic Pro wet behind the ears that I make newbies look experienced.  However, I'm not expecting many on the Apple support forums have a PianoDisc system, much less one with the new optical record strip.  While I don't have any record strip on my PianoDisc, I do have a PianoDisc iQ that's only a month old.  I've been playing converted paper scrolls from hundred year old player pianos through it via the MIDI in port of the PianoDisc CPU.  I've found I have to open the MIDI file in Logic Pro (10.0.4) then go to <Track><New External MIDI Track> then copy the existing track to that new external track.  Only then can I see in the Track inspector (defaults left side of screen with the Icon for the instrument) the "Port" parameter.  Then I can select my external MIDI device in that Port selector. 
    I've also encountered problems with the PianoDisc not using enough force on the notes or using too much force.  To get around this problem, until I understand Logic better, I've been setting minimum and maximum volicities.  To do that I right click on the track and select "Select All."  Then I right click again and select "MIDI" then "MIDI Transform"  then "Velocity Limiter."  In the resulting pop up window in the center is a drop down and you can play with the velocity from "MIN" to "MAX" along with "ADD" "SUBTRACT" etc. 
    I hope this helps.  I envy you your Mason & Hamlin.  If you need more help on this just email me at pfleischmann at mac dot com.

  • How can read BOM component date before save the production order??

    Hi Experts,
    In our company, we need to develop a program to read the BOM component data of the production order
    before we save the production order.
    That for example ,when we create and release a production order , before we save the production
    order,we want a porgram to read the BOM component data. If some component data can meet our
    requriement (may be if there is material requirement quantity>100 EA),then the system will pop up a
    small dialog box to remind us.
    There is user exit PPCO0007 and PPCO0007.But it seems they only can read the head data of the
    production order before we save the production order. And the BOM component data of the production
    order are saved in the RESB(Reservation Table).So if we do not save the production order,all the BOM
    component data are not saved in the RESB table.
    So how can slove the problem??
    How can read component date before save the production order??
    Are there any other user exit we can use???

    Hi Just wanted to check am I right that you are trying to check if you have enough Materials Available before you release or Save the order right ? if this is your business objective then when you create order you have material availability tab which checks and gives error if shortage is there. Please let me know if is this wht you asking for ?
