Keller leo 3 affichage de pression non continu

Bonjour
j'ai un petit problème j'ai développé une application pour suivre la pression en direct depuis un manomètre keller LEO3 et quand je l'ai introduit dans mon VI principal j'ai obtenu ceci (voir photo)
Il s'agit de la ligne bleue. 
Le suivi est discontinu et je ne vois pas pourquoi, quelqu'un aurait-il une idée?
je joint mes VI, une image du graphique et le protocole de communication et voici un site ou j'ai trouvé un exemple d'application (j'ai repris les parties qui m'intéressaient)

Bonjour, je ne peux pas regarder votre code car je n’ai pas installé LV2013 sur ma machine.
Mais quelques pistes et une explication possible des « trous » : des valeurs sont à NAN.
http://fr.wikipedia.org/wiki/NaN
En effet, si dans un tableau de nombre, vous notez « NAN » soit Not A number alors si vous voulez représenter le tableau dans un graphique LabVIEW, les NAN ne seront pas représentés. Donc des trous.
Peut-être que le NAN est causé dans votre code par une erreur de communication avec votre appareil. Par exemple si erreur alors dans le décodage de votre mesure retourne NAN.
Questions :
> Gérez-vous correctement les erreurs de communication avec l’appareil ?
> Avez-vous fait un export des données du graphique vers Excel pour « regarder » les valeurs ? (sur le graphique, clic droit exporter vers Excel)
Bonne continuation

  • How to display non-continuous lines in a 2D Line flash chart ?

    Hi
    I am making 2D lines charts. is there a way ig tehre are no data in the table, to not to display points ?
    For example I have a table with this data :
    Date     Value
    01/01/09 2
    02/01/09 7
    03/01/09 4
    05/01/09 3
    06/01/09 2You see in the example anove that there is no data for the day 04/01/09.
    I would like the chart no to display any point for that day and start again for date following. This means displaying a non-continuous line.
    I hope I am clear.
    I tried but had no solutions. Would you have any idea on this ?
    Thank you for your kind help !
    Christian

    Hi Christian
    You're missing a lot of the XML build up from the website.
    You also need to return the string "Missing" for each date that you haven't got.

  • 3rd gen 8Gb non continually reboots - what to do?

    I went to add some songs to my nano and iTunes said there was a firmware update, so I said yes to install it and when the iPod rebooted, it just kept rebooting again and again. The Apple logo shows up and then 5 seconds later the screen goes blank and it boots again. Has been doing it all day. None of the restore things work, probably because it hasn't booted far enough to work with the buttons. Doesn't show up when plugged into USB.
    Any ideas as to what to do?

    i had the exact same problem with firmware 1.0.2.
    had to reset by holding menu & select for about ten seconds, then
    pressing play/pause & select for another ten seconds to enter disc mode.
    i then reset the nano with itunes and downgraded to firmware 1.0.1 (after deleting the files iPod_26.1.0.2 and iPod_26.1.0.2.ipsw.signature (are in the folder *ipod software updates* somewhere on the harddisk)).
    now in works just fine with fw 1.0.1.
    fw 1.0.2 obviously contains a bug.

  • Waveform non temporelle et non continue

    Bonjour à tous,
    j'aimerai utiliser certaines fonctions de waveform sur mes signaux, qui ne sont pas sous forme de waveform. J'essaie donc de les y mettre, mais je n'y arrive pas.
    Je vous joins mon vi pour que vous puissiez mieux cerner mon problème.
    Les 2 tableaux d'entrées sont issus d'une DAQ et l'autre d'une acquisition de valeurs sur le port série. Ces 2 tableaux sont synchronisés, c'est à dire que chaque ligne des 2 tableaux correspondent (à peu de choses près) au meme instant de mesure. Ce temps est par contre non constant entre 10 et 20ms). L'aspect temporel, je m'en fiche, car Position me donne l'angle de mon système à caractériser (potentiomètre rotatif) et DAQ correspond aux ratios de tensions entre tension curseur et alimentation potar.
    Bref, j'arrive donc à générer 2 graphes XY qui correspondent à la caractéristique des potars, mais j'aimerai pouvoir utiliser les fonctions limtes de waveform pour vérifier que ces graphes sont bien dans le gabarit voulu, et par la suite, j'aimerai aussi utiliser la fonction "trigger". Hélas, je n'arrive pas à comprendre comment les utiliser avec mes données qui ne sont pas sous forme de waveform.
    De bonnes idées à me conseiller ?
    Merci d'avance,

    Bonjour,
    Les fonctions que vous souhaitez utiliser semblent intéressantes lorsque le
    signal possède une période d’échantillonnage constante, ce qui ne semble pas
    être votre cas (10 à 20 ms). Vu que l’information temporelle ne vous intéresse
    pas, vous pouvez par exemple utiliser la fonction "max et min d’un
    tableau" qui vous renvoie le minimum et le maximum d’un tableau ainsi que
    leurs indices pour obtenir le "gabarit" de votre graphe et vous
    assurer qu’il convient. Je vous invite aussi à prendre connaissance des
    exemples fournis dans l’aide détaillé de la fonction « Test de limite » qui pourraient vous guider.

  • Help selecting non-continuous text in code editor, please?

    I'm editing a list... I want to make a lot of selections at once and  edit them at the same time.  You know how you can go through files in  windows and ctrl+click/select files to move around?  I could do this in Notepad++ so I guess I could switch back and forth but that would be a big pain.  Any ideas?

    Depending on what the edit is, you could use the Find & Replace (CRTL+F) to just click your way through the list items. If the list is all different items, you'll probably have to do it in a word processor. I don't know any way to do it in the code editor.

  • How to deal with non-continuous shapes and graphic styles

    I am not sure how to frame this question so I will try to describe the problem.
    Imagine I have two shapes. One is a hollowed out circle (like a doughnut chart). The second is a smaller filled in circle. The smaller filled in circle is then poitioned inside the hoolowed out one, so you have like a target but with no "middle" band. What I would like to do is apply a graphic style to the COMBINED shape. The problem is that if I select both shapes and apply the style, each shape will have its own style, whereas what I want is for the style to be distributed over the two shapes as if they were one. And if I use the shape builder tool, when I join the two shapes, from the outer hollowed out circle to the inner filled in circle, I fill in the shape for the "middle band" whereas I want that middle band to be empty.
    You can probably tell I don't know Illustrator and come from Photoshop. In PS, I would simply select my two shapes and apply a style. Since my selection forms a shape that ignores the middle band, the style applies evenly to the whole selection. Can I do something similar in Ilustrator? In reality my network of shapes is more complex that the example above and I do need to keep it a vector.
    Thank you for your suggestions.
    Chris

    There are really two types of Graphic Styles - Object level styles and Group level styles. There is no way to tell which style is which. So if you have an Object level Style and try to apply it to a group of objects or often a compound shape, you get each individual object having the style. If you have a Group level style and try to apply it to only an object, you often get nothing applied.
    It perhaps sounds like you have an Object level style and are trying to apply it to a group.
    There's no way to convert an Object level style to a Group level style or vice versa. The best (and pretty much only) way I've found to get around this is to apply the style to teh correct level then make a note of all the style settings, select the other level and recreate the style for that level.
    Whether or not a style applies correctly has a great deal to do with specific aspects of the style in addition to what level the style was generated from. This is a frustrating aspect of Graphic Styles.

  • Non-continuous wan subnet

    Hi,
    We are assigned some IP’s from our ISP, Subnetmask /27. Actualy 217.x.187.194-198 and from 217.x.187.203-213 The IP’s between are given to someone else. This should be 30 available hosts. GW 217.x.187.193
    I will use the range 217.x.187.194-198 for my internal networks.
    Question. Will there be a problem not having entire full subnet or is this possible on the ASA 5505? Or should I ask for a complete range?
    Also, is there any possibility to do static nat through the asa and allow all traffic from IP 217.x.187.196 to another router on the inside. This router belongs to another company who needs to regularly open and close ports through to their company. we do not want to give out access to ASA.  
    Br
    Fredrik

    Hi,
    If we are strictly talking about having the 2 subnets on the WAN interface of the ASA then that is no problem at all. Though you have to consider the fact that ASA can not have 2 different subnet configured on a single interface (in your case a Vlan interface). But there is a way to implement that, the second subnet just is not configured under any interface. The subnet and/or its IP addresses are only present on the ASA in its NAT configurations.
    There is 2 ways you can handle this with your ISP
    You can configure the other subnet between your ASA and the ISP Router and request the ISP to route the second subnet towards your ASAs WAN interface IP address (that belongs to the first subnet)
    You can configure the other subnet between your ASA and the ISP can configure both of the subnet on their link towards the ASA. Even though the second subnet is not configured on your ASAs WAN interface you are able to configure NAT using the second subnets IP addresses on the ASA. In this case when traffic is incoming to the second subnet from the Internet the ISP router will send ARP requests for the second subnets IP addresses (as the ISP has the subnet as directly connected) and the ASA will respond to those ARP requests with its WAN interface MAC address IF there is a NAT configuration present. You will also have to make sure that the ASA is configured to answer to ARP requests on the WAN interface. If you were to go with this option then let us know the software the ASA is running and we can confirm what commands you need enabled/disabled.
    To avoid any ARP related problems and other problems I would suggest that you ask the ISP to route the second subnet towards the ASA WAN IP address. Much more simple that way.
    Now you mention that you want to do a Static NAT on the ASA for the internal router? This should be no problem and there should not be any problem allowing all traffic to the internal host when it has the Static NAT configured.
    Since you have 2 public subnets you also have the option to configure the second public subnet directly on the internal interface of the ASA and the other company can use the public IP address directly on their Router. Naturally configuring this second subnet on the ASA might waste some public IP address (since you need one for the gateway etc.) but it completely depends on your setup.
    Hope I made any sense :) Feel free to ask more if needed

  • Continuous stock definition

    Hi to all
    Nowadays in SAP BO 2007 A there some basis initialization as "Use Continuos Stock" that is a global definition for company.
    Since we have now the G/L Account Determination per Period, why not include also this defition related to Continuous Stock?
    We have an issue that we have because in Portugal related to Continuous Stock.
    In our legal system not all companies have to use Continuous Stock, but could be mandatory so some companies start without continuous stock but for some legarl issues must change to Continuous Stock.
    Now what we do here is the creation of new database with the new Basis Initialization.
    So if we have this definition in G/L Account Determination it will not be necessary to create a new database.
    Comment pleasethis issue.
    Regards
    Vasco Silva

    Hello,
    Thank you for this interesting request.
    As you know continuous and non-continuous stock (aka perpetual and periodic) inventory valuation concepts are completely different in regards to posting rules and valuation during the year. It is hardly a question of single switch. Therefore to implement control to change how company valuates stock requires huge development effort.
    You have noticed correctly posting period selection on G/L Account Determination form. This was implemented as 'current period' concept was left in 2007 version making user work more flexible. G/L Account Determination were set per posting periods even before the 2007 version but this was controlled by 'current period' switch.

  • Capturing continuous HDV over timecode breaks

    Hello! I hope someone out there can assist me - I've been searching google and doing some trial and error, but cannot find a solution.
    I have HDV video that I'm trying to capture into FCP 7. The footage has timecode breaks in it, some longer than others. I'd love to FCP to just gloss over them, ala capturing DV footage, but it seems it cannot.
    Re-recording is not an option as the client doesn't want to pay for the additional work. The capture itself is a byproduct of the videographer not remembering to compress live on site.
    Thanks for any help you might have!
    Additional info - capturing to a FW800 drive, Macbook Pro 2.2 i7 with 16GB ram - HDV coming from Sony HVR 1500
    Thank you!

    Can you get your hands on the same make and model camcorder that the footage was shot on?  I know this was suggested in a prior post and you said that you can't get the camera.  But, if you can rent a Sony HVR 1500 (I'm assuming it's a rental), can't you rent the same camera that it was shot in?  It's not uncommon to sometimes have to capture from the same device that was used to shoot the video in the first place.
    The drop frame error that you linked does not result from non-continuous time code.
    Also, the free run time code setting on the deck affects where it looks for tc source when recording (it doesn't affect tc during playback of a recorded tape).
    Based on everything in this forum so far, I'd suggest you go with Michael's suggestion and get a Blackmagic Decklink card (assuming that your computer can accomodate one).  Patching the SD-HDI out of the deck to the SD-HDI input of the Blackmagic Decklink should do the trick.  If you have something with HDMI out on it that can play the tape, you can go with Blackmagic's more affordable Intensity product that has HDMI in.
    Plan C would be to rent or buy a HD field recorder and patch the video out of the deck to the video in of the field recorder.  As long as the tape plays, you should be able to get it across.
    Good luck!

  • Ext3+dir_index vs JFS, XFS, ReiserFS. Choice problem

    I'm a linux noob.
    Going to install Archlinux to new laptop Inspiron 1520
    Right now playing with Archlinux on vmware.
    I want my laptop be fast, and of course choosing right FS is important in this regard.
    Let me sum up all i read so far about different FS.
    ext3 vs XFS, JFS, ReiserFS:
    - ext3 is most stable, most supported. But also slowest.
    - XFS, JFS, Reiser are much faster, but have stability and or support problems.
    - ext3 with dir_index is fast, almost as fast as others.
    - noatime,nodiratime considerably improve performance of all these FS
    So here are my questions.
    1. Will ext3 + dir_index + noatime,nodiratime be up to the par with XFS,JFS ?
    2. Does disr_index enabled by default on latest Arch or do I have to enable it manually ?
    3. What other advantages besides speed JFS,XFS have comparing to ext3 ?

    lucke wrote:Fragmentation can be an issue. <snip>....<snip>s impact on performance.
    Yes indeed fragmentation can cause a significant penalty in performance, especially if you are copying large, very fragmented files. But for a desktop system people usually deal with smaller files than ones downloaded in large torrents; at least that was my impression for my previous post. The thing about XFS being designed as it is, is that it doesn't handle fragmentation of large files well. Basically, the extensive use it makes of B+ trees make it particularly cpu intensive for working with reads that are non-continuous and hence is particularly hurt when copying highly fragmented, large files. This isn't quite as pronounced in JFS (but the performance hit is there) because it's cpu usage isn't as high as XFS; and it's algorithms are more optimized for working with smaller continuous reads than XFS (to my understanding). This is probably the main reason why XFS has a defragmentor and JFS does not.
    One thing that fragmentation of a JFS filesystem will have a major effect on is performance of a VMware virtual machine whose image is highly fragmented on JFS. I mentioned this in the wiki article. If you use VMware with a growing image, I recommend somewhat regular defragmenting of the JFS partition, otherwise the VM will be significantly impeded. I imagine this situation is true for other file systems other than JFS. Also, if you torrent frequently with large files, then I would suggest regular JFS defragmenting in this scenario as well.
    Gullible Jones wrote:Re JFS data loss: bug reports have been filed. See here and here.
    The first report is most likely due to the fact that JFS journals metadata only. This is also the case with XFS, Reiser, and ext3 (with the popular journal=writeback implementation). Caching data losses like the first bug report seems to describe what has been known to happen with other file systems on linux and not JFS. Nonetheless, JFS has never hidden the fact that it journals metadata only as journaling both metadata and actual file data incurs a big performance hit.
    The second bug report could easily be a hardware failure. Indeed with both the log and no inodes being dumped to the lost+found directory, I would not jump to judgment that this was necessarily a JFS issue as that would imply JFS failing in SEVERAL different places. It is more likely that the issue was one with hardware.
    As I said before, neither one of these show that JFS conclusively looses files in its own right. If you really require journaling of both metadata and file data, then ext3 is the only option for linux (with no journaling /etc/fstab optimizations); JFS and other journaling file systems don't do this as it significantly reduces performance.
    Anyway, I am done going on about this; if people are hellbent on believing JFS looses files, so be it. Personally, I have never had a data loss issue with JFS despite years of use and abuse in the spectrum of possible hardware and software configurations.

  • How to connect Mac Mini with LG 19LS4D LCD TV?

    Hi all,
    I just purchased my Mac Mini and tried connecting to my LG 19" HD TV using the supplied DVI to VGA adapter. When I first booted the machine "No signal" was displayed on my TV. I plugged in another 15" monitor and played around with resolutions and cable swapping and it works at 1024 x 768 at 60Hz (not ideal but better than nothing). Everytime I turn off the Mac Mini or it goes to sleep the resolution is reset and "No signal" appears again.
    I have tried connecting via VNC to play around with the settings remotely but this has no effect on my TV monitor and is only resolved by the solution above or by leaving my Mac awake and not sleeping.
    The documentation for the TV says that all the resolutions I have tried, and more are supported and Detect Displays under System Preferences shows these but defaults to a resolution that produces a "No signal" box.
    Any ideas would be greatly welcomed.
    Thanks in advance

    Hi BSteely,
    Thanks for the reply. To answer your questions, the LG shows on the mini as it should do i.e. there is a specific code (the LG model number) and lists the resolutions and refresh rates listed in the manual. Adobe Photoshop complains of a bad colour profile but I think that was only because when the LG is finally lit up it is as a result of me connecting the 15" monitor then hot swapping before OS X has change to realise.
    When using VNC with the LG attached 1024 x 768 at 60Hz is shown but selecting that does not show the screen on the LG.
    I did install SwitchResX from looking at other forums but was unable to save a usable state as the profile and resolutions were from a different monitor effectively despite my LG being connected. The P&D file that it gave back is listed in full below although I suspect this is for my 15"monitor (Excuse the length but I am unsure as to which bits are most useful).
    The LG manual lists 1440 x 900 at 60Hz as the native default however the mini fails to recognise this. The easiest resolution I can get after hot swapping monitors is 1024 x 768 at 60Hz although the other day (not sure how) I did get 1280 x 1024 (at 60Hz?). The LG does not however have a DVI port. It does have HDMI so a DVI to HDMI cable could work but without buying a cable I don't know.
    Here is the LG's information file:

  • External Display native resolution suddenly not available

    Hello,
    I'm using a Westinghouse LCM-22w3 external monitor with my MBP, connected via a DVI-to VGA adapter. I've used this computer/monitor setup for quite some time with no problem. Yesterday, I hooked my computer up to my 46" Samsung HDTV with no problem.
    When I hooked my computer back up to the Westinghouse, the native resolution (1680x1050) was no longer available. Instead, the monitor hooks up at 1600x1000. Strangely, though, the EDID information appears to suggest that 1680x1050 should be available. Here's the EDID:

    Any ideas? Switchresx didn't work, either

    Well, you can move the file from the desktop back to its original location to at least get back to what you had before.
    The file structure under Snow Leopard has changed and it's hard to keep up with this stuff. There is also now a com.apple.WindowServer.plist file in /System/Library/LaunchDaemons that you could try moving to the desktop and restarting. I dunno. Same rule applies.....if it doesn't help, move the file from the desktop back to its original location.

  • File Adapter: Different lines in one file

    Hi,
    I receive a flat file where I have to do content conversion.
    In this file, I have different structures which could appear unsteady.
    Means, every could structure appear in a non continuous way:
    File:
    struc1
    struc2
    struc3
    struc3
    struc3
    struc1
    struc1
    struc2
    struc3
    How to handle this in file adapter?
    Regards
    Chris

    Hi,
    do you mean like this:
    /people/jeyakumar.muthu2/blog/2005/11/29/file-content-conversion-for-unequal-number-of-columns
    How to identify the different structures? Every structure got different fields and different
    amount of fields.
    Every struc1 to struc3 should be a single message.
    And how to specifiy line break in file adapter?
    thanks
    chris
