IFM Octavis OPC server does not update

I am trying to monitor values from an IFM Octivas system using OPC server. Variant data will only update once after every computer reboot. Can read from Labview OPC Demo server fine. Can read all Octavis data but no update with Labview while Octavis Demo server can read the OPC data, so IFM suggests that the problem must lie with Labview.
Any suggestions?

Fred,
Can you read the value being updated directly from the OPC server?  Usually you can just view the values and see if they are updating. 
The next thing to check would be to use the shared variable monitor to see if the variables that are bound to the OPC server are updating.  It is under Tools >> Shared Variable >> Variable Manager. 
Also, when you have the program running, do you get any type of error from reading the shared variable?  If you are seeing an error, it would give us a little more insight into what is going on.

  • OPC Server does not update data value

    Hello,
    I have a problem with a program that uses an OPC server to comunicate with a PLC.
    It happens randomly, when I update the data, i cannot see any patern, sometimes it happens quickly, sometimes it takes longer...
    The data socket is declared like that:
    hr = DS_OpenEx ("psp://localhost/Server/Automate.405466", DSConst_WriteAutoUpdate, NULL, NULL, DSConst_EventModel, TIMEOUT_OPC_mSEC, &ecr_MW5465);
    And is update like this:
    hr = DS_SetDataValue(ecr_MW5465, CAVT_SHORT, l_buf, 1, 0);
    The function does not return any error, but the value is not updated server side.
    Lookout version is 6.6, the program is made with CVI 8.5.1 and communication is in ethernet modbus. I do not know if further details could be useful.
    Thank you.

  • OPC Server Connection not possible (with LabView 7.0 it is working)

    We have used LabView 7.0 to view OPC items on a remote server (Windows CE).
    On WindowsCE it's not possible to browse the remote registry, therefore we
    make the registry settings on the client Computer and are setting the
    "RemoteServerName". For LabView 7.0 it was working.
    With LabView 7.1 when we try the same with the sample "Browse to OPC Item.vi"
    we get the Message Box "NI Network Browser Error!" "This OPC Server does not support
    the interface: IOPCBrowseServerAddressSpace error code - 0x80070005 Access denied!"
    Has any one an idea what has changed since LabView 7.0.
    The OPC Server has also an OPCEnum running. Is there any way to read this information?
    Here are the whole registry setting for the local machine to connet to remot OPC-Server:

    Hi Robert
    LabVIEW 7.1 implements some new security features dealing with DCOM that were not in 7.0. Windows is moving in this direction, and National Instruments decided to follow suit. 7.1 requires a certain level of authentication from the server. If this is the issue in your case, it can be resolved with the following steps (this is for Windows XP; CE will probably be different):
    1. On the computer hosting your OPC server select "Start >> Settings >> Control Panel >> Administrative Tools >> Component Services.
    2. On the tree on the left, expand "Component Services >> Computers >> My Computer >> DCOM Config.
    3. Your OPC server should be registered as one of these items. Right-click on your server and select "Properties."
    4. On the "General" tab, change the "Authentication Level" to "Connect."
    If this property is already set to Connect or Default (and the default setting is Connect) then this will have no effect.
    You can also try checking some of the other settings:
    1. On the computer hosting your OPC server select "Start >> Settings >> Control Panel >> Administrative Tools >> Component Services.
    2. On the tree on the left, expand "Component Services >> Computers >> My Computer
    3. Right-click on My Computer and select "Properties."
    4. On the "Default Properties" tab, make sure "Default Impersonation Level" is set to "Identify."
    You may also want to look at the "COM Security" tab to make sure your computer has the right permissions.
    If all else fails, you can try adding the line "ole.AuthnLevel = 1" to the LabVIEW.ini file. This should reverse some of the changes to 7.1.

  • "The iPod software update server could not be contacted. The Server does not support this version of iTunes." Any thoughts? Also, iPod will not turn or or charge (tried in my laptop, house computer and dock) I have all the lastest updates to my knowledge

    "iPod software update server could not be contacted. The Server does not support this version of iTunes." iPod will not turn on or charge or reset settings. I tried plugging it in my laptop, house computer and docking station to charge and nothing. Also, I have all the latest software updates to my knowledge. This is a classic 8GB iPod, running of Windows 7. Any thoughts/suggestions?

  • Updated my phone, now e-mail will not send because server does not allow relaying

    Updated iphone 3GS to iOS 5, now my company e-mail will not send "because server does not allow relaying".  I'm just an employee, not an IT type - have no idea what this means and I'm very frustrated. Also infuriated with Apple because THEIR update caused this to happen, yet I have to PAY for their support because I have an older iPhone. Someone please help.

    razmee209, thanks for your reply. After signing up for the community, I saw that I wasn't the only one. However, I think I've solved it by looking over the comments in reply to others with this problem.
    First, I think the iOS5 update may have made the phone default to IMAP setting. I noticed when I deleted my account and re-set it up that there is a large button at the top for either IMAP or POP. It is already defaulted to IMAP, but my account must be POP.  So this is the first thing to check when you're setting up your account.
    Second, I noted some other comments about needing to supply a username and password to the outgoing server even though it says optional. I included those, but got a message that it wasn't recognized (or something like that) and did I want to continue anyway. I told it to continue. After a few seconds, it verified my account, and now everything works.
    Hope this helps others having this problem.

  • I suddenly cannot email photos from iphoto. I get a box that says "server does not recognize username or password". I now have to use regular email and cannot re-size my photos.

    Suddenly I can no longer email photos directly via iphoto mail.  The box comes up that says "server does not recognize username or password".  I used to be able to re-size my photos before sending so that they jpeg or pixels were larger for publishing in newspapers or magazines, but I can no longer do that.  Apple tech support told me to change my iphoto "preferences" to using regular email to send.  But that does not allow me to re-size.  Is anyone else having this problem?  I don't know if there was an update that caused this or what?  Please help.

    The box comes up that says "server does not recognize username or password".
    That error message usually will pop up, when there is a conflict between the "From" setting for the mail account you are sending from and the selected outgoing mail server. Probably the outgoing Mail server is receiving a user name and password it does not understand. When the mail returns unsent, do you see the "Try again" panel with the option to select a different outgoing mail server?
    If you do not see this panel, change the Mail "Preferences > General" to "If Outgoing server is unavailable: Show a list of alternate servers". This way, you will know, which server Mail is trying to send from.
    Have you tried to set "From"  pop-up menu to one of your other email addresses?  If that works, change your settings in Mail to always send from this address. You can set this option in the Mail "Preferences > Composing: Send New Messages from". I have my "Send New Messages from" set to "iCloud". That is working best for me with iPhoto.

  • Server does not recognize email address

    I have both an iphone and an ipad until today I was able to send emails from both units using my household internet connection, today when I try to send an email from my ipad I get a pop-up stating server does not recognize the email address, but I can send emails from my iphone using the same internet connection. When I checked the settings both units have the same. Two days ago both units were updated.

    Both devices are using the Home Network. My ISP is  Shaw in Canada. and they will only accept sent email from their subscriber households, for example if I try to send an email from my iphone via 3g it will not be recognized, but will be ok if sent using wi fi at home. I was able to send email prior to doing the last update.

  • Server does not work in yosemite

    Help!  My OS X Server does not work after upgrade to Yosemite!  Disaster!!!

    After the disappointment that I cant manage the servers running the previous versions of OSX server from my upgraded desktop. I upgraded my office server to 10.10 Yosemite with OSX Server 4.0 I am still not able to connect.
    I can remote desktop into the server without a problem (both are on the same LAN with the server on .local). But the Server app is not able to connect.
    Actions taken so far:
    Update software on desktop to 10.10 and Server 4.0
    Update software on server to 10.10 and Server 4.0
    Verified connection by pinging IP and .local
    Verified to connect to the drive and screen sharing via local network
    Rebooted router + switch
    Rebooted desktop + server
    If you manage OSX servers for clients, keep a system on 10.9 around so you can still keep your business running.
    Upgrading the server needs to be done on site with display, keyboard and mouse connected.
    Apple please fix a.s.a.p.

  • The past few days my Mail app has started downloading multiple copies of e-mails from all pop servers.  This is only happening on my Macbook not other macs.  Deleting mail from server does not help. I ran ClamXav found 2 viruses deleted problem continues

    opps.  Long title there... The past few days my Mail app has started downloading multiple copies of e-mails from all pop servers.  This is only happening on my Macbook not other macs.  Deleting mail from server does not help. I ran ClamXav found 2 viruses deleted those.  Checked for software update and installed suggested downloads.  Problem still contintues.  Any suggestions?

    Folks,
    even after having repaired the inbox folder under "properties" a few times, I still had some e-mails where the contents are different from the subject line.
    In other words in the inbox there are two e-mails: one with subject line "abc", and another one with subject line "def".
    When I display the e-mail with the subject line "abc", the contents are from the e-mail with the subject line "def" in the in-basket.
    What else can be done to correct this problem?
    Thanks and best regards.
