How can I filter J1939 CAN messages by Command Byte. (NI-CAN)

We have customers who use the first byte of data as an additional header byte. They have the usual J1939 extended header along with the first byte. Does anyone know of a way to filter on this in "Measurement & Automation Manager" (NI-CAN). We then bring this data into our VB6 application using the NI-CAN API. But I always need to write extra software to filter on the Command Byte (first byte of data).

You have to have at least LabVIEW 6.1 to use the NI-CAN 2.2 driver. So you might be OK running it on a Win95 machine.
I didn't find anything saying that it won't work on Wi95, it may not be supported, which just means that if you run into problems, NI support probably will not help you. On the download page for the driver, it says it supports Windows 2000; Windows 98; Windows ME; Windows NT and Windows XP. They may have indeed dropped support for Win95. LabVIEW 7.1 will not even install on a Win98 or 95 machine, so they may have done the same for the new CAN driver. Only way to know for sure is to try it.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

  • .xlsm Can't exit design mode because Control 'Command Button 3' can not be created

    I have several Windows 7 Enterprise machines that cannot open one .xlsm file properly. When it opens, it is opening in Design mode rather than as a spreadsheet with macros. My users are getting the error "Can't exit design mode because Control
    'Command Button 3' can not be created". All our machines have Office 2010 ProPlus, but this file will only open on the XP PC's that have yet to be upgraded. Any ideas?

    Hi,
    How do you create the button in Excel 2010? Just insert the control manually or insert it using a macro?  This issue may be caused by the controls aren't instantiated before you can exit design mode.
    Please try the method:
    Code can only run after all controls are instantiated and properly connected. Make sure every file needed for the control is available before trying again.

  • Why can't I receive any messages through Thunderbird, but I can read them on the server?

    my mail server is email.it

    SMS (text messages)  are cellar only, they do not use internet connection it's a service provided by your cellular carrier
    iMessage can use both internet and SMS, if iMessage cannot send via wifi it will fall back to SMS
    if configured to do so. iMessages can only be received by other iMessage users , iPhone, iPad etc
    iMessage is part of messages which can be turned off/on and has various setting that can be enabled/disabled
    if you message  someone who does not have iMessage enabled or has no iMessage your message is sent as a SMS message over the cellular network
    depending on how it is configured

    I definitely want this error cleared up for you! When you get this error, is your phone using the cellular data or wifi data? Do you have any issues getting into your email via the web browser?

    Hi Carol,
    Thanks for visiting Apple Support Communities.
    Start with these steps if you are not able to send iMessages to a specific contact:
    If the issue occurs with a specific contact or contacts, back up or forward important messages and delete your current messaging threads with the contact. Create a new message to the contact and try again.
    If the issue occurs with a specific contact or contacts, delete and re-create the contact from the Contacts application. Create a new message to the newly created contact and try again.

  • Exchange issue: send/receive mail fine - can't delete or move messages

    Just installed Snow Leopard this morning - excited to finally be able to hook into my company's exchange server. Everything appears to be functioning fine (I can receive and see all messages in my inbox, I can send email fine) however when I try either delete a message or move a message to another folder I receive the following message:
    "The message "XXXXXXX" could not be moved to the mailbox "Trash - [email protected]"
    An error occurred while moving messages to mailbox "Trash - [email protected]""
    Any ideas? Thanks in advance for any advice/help!
    EDIT: I am not currently aware of what exchange version my company is using.
    Message was edited by: Tyrun

    I'll third the post. Identical problem, but I'm one of the Exchange 2007 e-mail administrators, so people ask me for answers. The autodiscover worked, so I know the settings are correct. Mail, iCal and Address Book all had no problem with the sync. I am also not being blocked by the firewall.
    I'll start tweaking settings and see if I can make any progress. Just to reiterate what was stated by Tyrun, I can receive and send messages, but I can't move or delete (send to Trash) any messages. I'm running Snow Leopard, which was upgraded from an out-of-the-box fresh install of Leopard on a brand new MBP. All Software Updates have been applied.

  • How to Multi-Map N:1 messages in BPM when N is unknown

    I need to perform an N:1 message mapping in a transformation in an Integration Process. SAP Documentation explains how to do this:
    [http://help.sap.com/erp2005_ehp_03/helpdata/EN/21/6faf35c2d74295a3cb97f6f3ccf43c/content.htm|http://help.sap.com/erp2005_ehp_03/helpdata/EN/21/6faf35c2d74295a3cb97f6f3ccf43c/content.htm]
    But it seems to be the case that the first message of the source will be contained in a <Message1> </Message1> element pair, the next message in <Message2> </Message2> element pair, etc.
    So what do I do in the case of a variable number of input message that get mapped to one message? I don't know how many messages will be coming in before the mapping needs to be done; it depends upon how many messages are sent out in a fixed time interval.
    I will be using an ABAP XSLT transform to do this. I cannot use a
    <xsl:for-each select="Message">
    Kind of construct because each message is enclosed by a different <MessageN> element.
    This must be a problem that has come up before. Can anybody please point me to the solution?
    Kind Regards,
    Tony.

    Hi Anthony,
    Yes you can perform N:1 message mapping using BPM by just using a "wait" step. Its very simple. The "wait" step waits for a particular time period or scheduled time(like  25th March 10:00 PM).
    If only "collection of input messages for a particular time interval" is your concern, then I think you can just do it with a simple BPM and no need of ABAP XSLT maaping. It can done by a simple Message mapping itself.
    I can send you screenshot of a sample BPM which does this work on your mail Id if you are interested. Plz provide your email ID.
    If I havent understood your Qn properly, plz do inform.

  • When I update my nano ipod I get an error message "User ipod cannot be updated.  The disk couldnot be read from or written to."   How can I overcome this error message.

    In the iTunes window, when I update my nano ipod, I get an error message "User ipod cannot be updated.  The disk could not be read from or written to."   How can I overcome this error message.

    Hello there dilip77707,
    It sounds like you are getting this error message that your iPod cannot be read from or written to when you are trying to update your iPod Nano. I recommend the troubleshooting from the following article to help you get that resolved. Its pretty straight forward, just start at the top and work your way down as needed:
     'Disk cannot be read from or written to' when syncing iPod or 'Firmware update failure' error when updating or restoring iPod

    how can i stop an error message that comes up when i am using word? the error message is "word is unable to save the Autorecover file in the location specified. Make sure that you have specified a valid location for Autoreover files in Preferences,…"

    It sounds like if you open Preferences in Word there will be a place where you can specify where to store autorecover files. Right now it sounds like it's pointing to somewhere that doesn't exist.

  • How can I output multiple IDOC messages in one dataflow in DS 3.2?

    Hi, we are trying to load some business partner data into CRM through an IDOC. The specific IDOC we are attempting to use is CRMXIF_PARTNER_SAVE_M02. We successfully created a Data Services flow which takes input from a file and can write out an IDOC message which updates the record in CRM. The problem is that we can only manage to run this job for one record at a time - if the file we are using for input contains 2 or more records (2 or more business partners which we are trying to update), then the batch job fails with the error message:
    IDoc Error: Message:      Adding this segment exceeds maximum allowed number of repetition E101CRMXIF_PARTNER_KEYS
    I'm guessing from this error message that it is trying to shove both business partner records into one IDOC which is not supported by this IDOC. Instead what we want it to do is send 2 IDOC messages to the server, one per business partner.
    Does anyone have any suggestions on how we can make this work?
    Thanks

    I am trying to update the ABCIndicator from 2 to 3 and hence have set the Flag to X in the source table as well. I have updated the EDI_DC40 mandatory schema with the necessary values and mapped the values to the schemas in the IDOC
    E1FUNC_LOC_CHANGE - from the source table 
    and sub schemas
    E1BP_ITOB - some from the source table and other values to NULL
    E1BP_ITOBX - FLAG X to the ABC Indicator from Source table and all others to NULL
    E1BP_ITOB_FL_ONLY - NULL for Everything
    E1BP_ITOB_FL_ONLYX - NUll for everything
    I have tried to play around the FROM cluase in the query as well as UNnesting...all of them failed to resolve the issue...Can you please suggest me where I am going Wrong..
    Thanks
