Does OPC UA Shared Variable Server support Alarm&Event and historical access?

OPC UA Shared Variable Server is a sample code and resides at https://decibel.ni.com/content/docs/DOC-25602
It seems to support DSC <-> OPC-UA tag synchronization.
But does it support alarm&event and historical access?
I tried to open it with LabVIEW 2012, but lots of VIs were missing in the code, and I am not familiar with DSC and OPC-UA.

Hi iCat,
From your post on the example itself, a colleague of mine responded with: "This uses the OPC UA server included in DSC 2011 SP1 which does not include direct support for Alarms and Events. However you could use this idea to synchronize to shared variables on a Windows host which could have those abilities enabled."
So it looks like it doesn't directly do this.

  • Does smb in 10.8 server support NTLMv2?

    Does smb in 10.8 server support NTLMv2? If so, how do I enable it?
    Smb worked just fine in 10.6, but after upgrading to 10.8 its broken when windows machines try and connect. It works if I disable the requirement for NTLMv2 on my windows 7 clients, but that is a very poor solution.
    I tried putting "client ntlmv2 auth = yes" in /var/db/smb.conf but that didn't fix anything.

    Wow.....that's fantastic!  I couldn't understand a word from my supplier before.  Now it works, thanks Tom! 

  • How to add a new Shared Variable programmatically to an existing and deployed library?

    Hi there!
    I am trying to accomplish this on both LabVIEW 8.6 and LabVIEW 2010 and seems like it's not any different in this situation.
    My case: A project has a library with 4 Shared Variables (SVs). The library and the variables are deployed (visible in Distributed System Manager 8.6/2010). I want to add 2 more variables into this library. It is possible to do this manually from Project Explorer window's options menu. But while running an application it has to be done programmatically. Can I provide the library reference to the one currently existing without creating a new one?
    "Create Or Add Library To Project" function in the Datalogging and Supervisory Control (DSC) toolkit does not help in this case. That function, as the name suggests, just tries to create a new library in the project.
    Two possible methods:
    The function "Add Shared Variable To Library" (DSC>EngineControl>Libraries & Processes) needs a library reference, which could be provided via "CreateOrAddLibraryToProject" function, but this function tries to create a new library, and if I provide the path of the existing library it throws an exception that the library already exists in the project (yes, as I wrote above, I need to add new variables to an existing and deployed library).
    OR
    The function "Create Shared Variable" (DSC>EngineControl>Variables & I/O Servers) will add Shared Variable in a process, and not physically in a library file, and the problem (limitation) with this approach is that it doesn't allow to add complex data type Shared Variables (for example in LabVIEW 8.6 it has only 4 datatype options in input parameter, and even in LV2010 it does not have "Image" datatype that I need).
    The scond method is my preferred method as it allows to work on Online Shared Variables and doesn't create them physically in libraries (and this is good as the variables' scope remains only till the Variable Engine is running). But it doesn't support advanced data types, and the first method is powerful in terms that it supports to virtually any datatype, it just seems tricky to get that reference to the library.
    Any tips?
    Thanks ahead!

       <<<<>>>>   
    As the above two images show, while a library does not exist, it is easy to use the "CreateOrAddLibraryToProject.vi" which will add a new library to the project (if it doesn't exist on file system, a new library will be created) and that way, using the reference (the green wire going out from the function and the Case Structure, can be used to add Shared Variables to the library. The problem was what to do when a library already exists in the project, how to add more variables to it. I was looking for a way to get a library reference, and somehow I could not see it inside a Project's property (VI Server functions). Hence I posted the question. And upon continuing my search, I found it on the Application's property list.
    I hope it was useful for someone else as well. And thanks for the replies. Please share a better idea if you have.

  • Which application server supports EJB 3 and Java EE 5?

    Hi all,
    I want to develop an application using EJB 3.
    I was planning on using JBOSS 4.0.4 as application server, but I am not sure whether EJB 3 is fully supported.
    Which application server supports EJB 3 and Java EE 5?
    Thanks

    Just install it using the EJB3 profile in the installer. Don't use the "All" profile
    and think EJB3 is included in it :)

  • Shared Variable: Server Failure

    I'm binding Labview 8.2 Shared Variables to Fieldpoint channels, using OPCFieldPoint Server. The OPC Server works properly, i can connect to it using Server Explorer 2.4.1 and see all the channels (though i had to do a repair installation of Fieldpoint 5.0.1 to obtain this!). But Shared Variables bound to OPC Items don't work, i get "Server Failure" error both in Variable Manager and in project VIs.
    Fieldpoint channels are visible in MAX, and readable using direct Bind to Source. Just OPC and NI Variable Engine don't seem to talk to each other, though everything is on the same machine. I have even set up the SVE as explained in http://digital.ni.com/public.nsf/websearch/8719713F089653C1862570F10074E06B?OpenDocument and set an administrator account (do administrators always have DCOM privileges?).
    Thanks for any help!

    With this kind of "intelligent" FP, you don't need to use OPC!
    You can create your variable and write in it in the field point, and read it from the PC, as you can see in the example picture i attached.
    You do this simply using the variable engine.
    Ciao!

  • Shared Variables should support LVOOP as a data type

    Almost all LabVIEW data types can currently be sent through a shared variable without any hassle.  The notable exceptions are native LabVIEW classes, which cannot be selected as the data type for a shared variable.  This causes a problem for anyone who wishes to send objects across a network.  They are forced to rethink their use of LabVIEW classes, use a communication method other than shared variables, or flatten and unflatten the object on either side of the shared variable communication.  The use of classes is growing more common with every version of LabVIEW, so I think it is time for these two prominent LabVIEW features to work together seamlessly.

    There has been some debate (both within NI and with customers) about whether or not the flattening/unflattening solution is actually desirable. After all, if NI made the shared variable support classes, to do the writing to the variable, the object would be flattened to a string and then unflattened when the variable is read. In other words, having the shared variable support classes does not actually remove any work that the program has to do, so having the shared variable do this behind the scenes is just syntactic sugar. The negatives crop up with the issues that Phillip raised -- suddenly the shared varible is reporting a number of errors that it did not support previously, whereas by separating the (un)flattening into a separate node, it is easier to tell where an error is arising -- was it a failure to read a shared variable or was it a failure to unflatten the data therein? By keeping the shared variable ignorant of such complex data types, it is easier to swap out the communication mechanism used -- shared variables might get support for LV classes, but TCP/IP prims might not, or whatever other communication protocol comes along in the future (i.e., the network stream primitives that are brand new in LabVIEW 2010 -- effectively queues that are usable over the network).
    Users may choose to create a custom string format for objects, one that can be unflattened by any system that uses the shared variable -- including CVI and MeasStudio. Having shared variables support classes directly does not get in the way of this, but consideration of exactly what private fields actually need to be exposed in that very global global variable might be encouraged if users are consciously aware of the serialization taking place.
    I'm not pro or con this feature at this point... this post is merely to document debate I've heard about any intermachine communications protocol handling LV classes directly.

  • Does the XMLP full or partially support the Xpath and XSLFO syntax?

    Does the XMLP full support the Xpath and FO syntax? or partially? Thanks

    Hi Robin
    OK, so hopefully you are not leading me into a trap here :o)
    There are two parts to this question:
    1. XPATH - we support as much of the XPATH spec as the Oracle XDK supports ie we rely on the XDK for our transformation engine so as long as they support what you are trying to do then we do. There are a few gaps and we have plugged those in the XMLP layer. So the short answer is yes.
    2. XSLFO - we allow you to use XSLFO in your template. The XMLP engine supports much of the standard but there are a few gaps. the next set of docs will layout exactly what we do support in the spec.

  • Does the 27" iMac wireless card support 802.11a and n

    does the iMac support the 5 GHz wifi format?  How about the N spec?

    I'm sorry but I don't understand this:
    the unit supports 802.11a channels but it doesn't pick up anything.
    Are you saying the iMac cannot connect wirelessly? And why would you be concerned that the very old 'a' standard may not be picked up? The latest standard is 802.11n, not a.
    http://en.wikipedia.org/wiki/IEEE_802.11
    So, is the iMac working wirelessly or not?

  • Mail on iMac not accessing MS Exchange server but both iPhone and iPad access the same account with no problems.

    I have been using an iPhone and iPad to access my work emails via our MS Exchange server for a number of years now with no problems at all.  I recently replaced my home PC with an iMac (first Mac I have owned) but cannot get it to communicate with the exchange server.  I've checked and re-checked the information on the iMac and my iPad - I even deleted the mail account on the iPad and input the details concurrently with setting up on the iMac - but the Mac will not access the exchange server.
    I receive the message "The Exchange server "---------------" rejected the password for user "------"  Enter you password again or cancel."  I am using the correct password.  iPad and iPhone are logging on using that password fine.  iMac just ends up repeating this message.
    Our IT support at work assure me that there is no reason from their end for it not to work, and reasonably point to it working using the iPhone etc.
    I'd be extremely grateful if anyone can provide a solution to this basic, but extremely frustrating, little problem.

    iPhone and iPad use a different way of accessing the server.
    I don't know the exact details, but we are using Zarafa instead of Exchange and have the same problem:
    iPhone and the likes can connect to Zarafas z-push interface, which is some identical interface to the native Exchange interface, while the desktop e-mail application tries to interface with the web front end (via http) of the server.
    These are completely different setups and it depends on the actual installation of the server to get this going.
    So, you will most likely need different access parameters for the desktop - and the web mail feature has to be enabled on the Exchange server.
    In my opinion using the web mail interface is just silly. On the other hand, the native protocol has less features comparedto the web front end, so you are somehow stuck with sins of the past.
    Good luck!

  • Why does iMovie has clumping in dark areas in events and after export

    I coverted some Sony .mts files to .mov's via Wondershare. The .mov previews looked perfect in playback with QuickTime player, so I imported them into events. My importing 'events' preferences are 'original size'.
    I didn't see the choppiness in my darks until after I completed the project! I did not finalize the project yet, just exported to Vimeo and facebook.
    It shows up pretty well at about 1:20 min
    https://vimeo.com/55162309
    Is there a way to fix this? What did I do wrong?
    Thanks!

    What you're noticing is called COMPRESSION ARTEFACTS
    (I downloaded your original file from vimeo, if this is ok for you)
    instead of detail, tiny leaves etc, we see 'posterized' areas, square 'blocks'.
    there are diff. methods happening while compression: reducing detail, reducing colors, condensing 'similiar' content to one solid block etc.
    What you did wrong?
    a) the recording situation was perfect - nothing wrong here, except …
    b) was the cam set to maximum quality?
    c) manual converting? why that? the intended way is going straight from SDcard into iMovie.
    d) conversion anyhow? mts is a wrapper, inside is h264. no conversion needed, just a re-packing into mov.
    e) does Wondershare etc convert into ... what? My assumption is h264 in a mov. converting h264 into h264 is a lossy process.
    f) … with what settings? (double click such a mov, cmd-i - what is said about bit-rate ? my assumption, some silly low one. in effect: the compression artefacts, which ARE in the original recording (not visible on playback) get MULTIPLIED ... and, on low bit-rate, downgrading the quality.......
    g) seems like, you choosed good export settings from within iMovie (720p with 9mbps)
    h) Vimeo converts finally again .... (lossy process again)
    summarize:
    • set your camera to max quality/bit-rate
    • avoid Wondershare (and any other converter) by using iMovie as intended
    • if manual conversion is needed, only straight from h264.mts to AppleIntermediate (or proRes, if avail)

  • To free up some space on my ipad I need to delete some photos. If I do this does it delete them from my Mac Desktop events and albums?

    Have  no idea whether this will help you, however...
    I Have had several problems with my Ipad Air since upgrade, crashing, telling me I had no memory, plus stupid icloud wanting me to log in all the time.
    i Did a reset, still same problem. I have very little on my iPad, so should have had lots of space left.
    eventually checked out iCloud and found that it has been backing up 2 previous ipads, and both our phones. I have deleted them from this ipad and bingo all my memory is back!
    give it a try, go into your ipad account and see what it is up to.
    my last problem now is when I start to type, I only get the first letter out before it stops, second go works????.
    no idea why these updates have to be so large, but then I don't work for Apple LOL
    shouldnt continually have to buy new devices, they should last much longer for the price, so we continue to look for solutions.
