Cluster elements limit

Hi!
I have problem with big cluster. Big meas that it has 1000 or maybe even more elements, such as numeric, string, boolean, ..., that are in subclusters. Memory that it allocate is less than 5MB. Problems starts when I try to do anythih with it (move, resize, copy, save VI), CPU usage jumps to 100% and it takes some time to drop down again. Next, if this cluster is a constant and try to change it to control, it is not visible on front panel. All I can see is label of that cluster. I need that big cluster because it contains setting of an vision algorithem.So I wonder if there is a limied number of elements in cluster or some other restrictiuons regarding usage of clusters
Thanks,
andrej

Hey,
I build a cluster which is a combination of 8 clusters with each 256 elements. When creating an indicater of that cluster i cannot see it in a proper way too. What I think is the limitation of the frontpanelsize which makes the cluster appear in that way.
I would suggest you should splite your cluster in several sub-clusters and just use the bundle/unbundle function to handle it in the blockdiagram.

  • Change properties of a cluster element withing an array of clusters

    Hello all,
    I have an array of cluster that is shaped as a line with different display elements.
    A list or a tree wouldn't have made it, so I had to use a cluster and make a table.
    The problem is that I want to change not only the text but also the text color.
    Individually.
    I found this :
    http://www.ni.com/example/30904/en/
    But it change the property in all the clusters in the array, not just the one I need.
    Some people have the same problem :

    Obviously, while in a list/table or tree you can change the property of an individual
    cell (font, color) you cannot do it within an array of cluster, by some sort of magic,
    the property of a cluster element (font, color) are all linked together, hence rendering
    the use of an array worthless.
    A possible hack is proprosed by using control masking, setting one visible and the
    other invisble, swapping their position, whatever. It's a hack you have to perform,
    hence add another code to maintain.
    Is that still the case or is there now a more official way to handle individual cluster
    properties, not just its data ? After all that's a common real-life example that should
    be handled by Labview. In my opinion.

  • Determine cluster element clicked in mouse down event

    Is there anything similar to the ArrElem Property Node, that allows a user to detect which element in an array has been clicked on (mouse down event), but for a cluster?
    It seems the only way I can detect which sub-cluster in my main cluster (see attachment) has been clicked on, is to work out the screen coordinates of each element and compare that to the mouse coordinates of the click - is there any other (better) way?  There's is going to be eight of these main clusters all stacked vertically.
    NOTE: All sub-clusters in the main cluster are disabled so that nothing "pops-up" when the user clicks on an object.
    I was thinking of using an array of clusters, but I need the ability to set various properties (eg. blinking) for each individual object.

    That's not bad Ben - thanks.
    I made up a quick VI based on your solution which works great if I have one cluster, but if I have eight+ Main Clusters I have to repeat this Event eight+ times - no?  I was wondering if there was a more scalable solution?
    I suppose I could just lump ALL the sub-clusters into one massive Main Cluster, but the text string for that Event is going to be very, very long eg. "Main Cluster.Cluster1"....."Main Cluster.Cluster24": Mouse Down

  • Property node to cluster element

    Hello All
    When clicking at the control cluster element you can create a property node.
    But if right click on property node you can NOT Link to the cluster element.
    How it is possible, that you can do it only in "one direction"?
    Pawel

    Have you looked at creating a property node for the cluster and using the Controls[] property? Controls[] is an array of control references for the elements in the cluster. The array is ordered in the cluster order. If you're doing the same operations on each cluster element, you can put the operations in a loop autoindexed by Controls[]. If you're doing different things for each cluster element, you could create a state machine controlled by the Controls[] index. The property nodes for the indiviual elements will be disconnected from the controls, then the control reference indexed (or autoindexed) from Controls[] will be wired to the reference input of the property node.
    You can get a disconnected property node from the Commun
    ication >> ActiveX function palette, or your can create a property node for any control, then right-click on the property node and select Disconnect From Control. Don't worry about the label on the disconnected property node until you wire the control reference to it. It will automatically adjust based on what it's wired to.

  • Broken cluster elements

    Sometimes when I load my rather large Main VI it comes up "broken arrow" even after saving it after correcting the errors. I usually have to go 3 or 4 subvi's and relink broken cluster elements. The elements are there, and there may be a dozen broken wires to or from the cluster, but once I reselect the first element all the others relink and it's fine. Its always the same clusters in the same vi's. If I save it and reload, sometimes it comes back OK but sometimes it comes back broken and I have to relink the cluster elements. This is very strange. Has anyone else seen this?

    I don't have any good reasons why your cluster elements would become broken, but I do have a suggestion.  The rule that I follow is that if I am going to be using a cluster in more than two places I will go ahead and create a type def. for it.  This would make it easier for you to add to the cluster in one place and have it update everywhere, and it should help with these linking errors.  If your cluster is a constant, a quick trick is to change it to a control, create a type def. for it.  Once you have replace the cluster control with the type def., change it back to a constant. 
    Hope this helps!

    This can become arbitrarily complex, because a cluster can contain many types of data, even other clusters, arrays, typedefs, etc. So getting a "value" of an element is not as easy as you might think. There is a reason you get a variant.
    If all cluster elements are simple numerics you can use "variant to data" with the correct type. The attached shows a few possibilities. Modify as needed.

  • Dynamicall​y instantiat​e cluster elements

    Hi,
    Is it possible to instantiate new elements in a cluster while the vi is running? I would like to have my vi search a directory and for each file in the directory create an element in the cluster. However, I do not know ahead of time how many files there will be. In addition, the type of cluster element that gets created depends on the file. For instance in the case of one type of file I would like a multicolumn listbox to be created while with a different type of file I would like an array to be created. Is it possible to do this dynamically? Thanks in advance,
    Jason

    Thanks for the quick response, but I'm not sure how this does what I want. I would like the cluster and the front panel display of the cluster to be programatically updated based on the number and types of files found in my directory. Thanks,
    Jason

  • How to connect external inputs into cluster elements?

    Hi all,
      I have a subvi have a cluster embeded

    udka wrote:
    One way is unbundle cluster, get the outside value from enable control and again bundle it with other two values. Since that is cluster, group of all those three you can connect entire cluster as terminal.
    Thanks for reply. What I want is to update one element in a cluster and keep the others elements unaffected. If I understand you correctly, you suggest to pass the cluster strcutre from outside the vi, unbundle it inside the vi, using the enable value from outside and other two elements from inside to bundle a new cluster and pass it to the vi's original cluster. Yes, this way works. But in my future development, I have a very big cluster with so many elements, I just want to update few of them and keeps the others unchanged. The way you suggested works but not that practical. Is that any simple way to do that? Thanks.

  • How to replace cluster element in an array?

    hi,
    I have understood preferable choice is to initialise array first and replace elements in an array instead of inserting new element in an array e.g. in a while loop.
    So I started to this evaluate since I have an application where I want to read lots of measurements from a txt file and display them in a XY graph. XY graph must show Y value and corresponding X value either red if it is out of range and in green if it is in range. I found a solution to do it with an array of clusters.
    In attached example I have two different methdologies represented. My problem is that upper solution doesn't display content of all measurements. Can somebody tell me what I'm doing wrong ?

    That is an odd thing and makes little sense. Why three? four, five, etc are NOT supported, so what if you want more than one color? (in range, fail high, fail low?). For more detail see the discussion here.
    In any case, reading all these values from a datafile and creating xy plots is trivial. I would recommend to use complex data. a single complex array will graph IM vs RE. For multiple plots, combine them using "build cluster array". No loops needed.
    Here's a quick draft. Of course you need to decide if the data is in columns or rows, etc. so modify as needed.

  • Change a cluster element value

    I have an array of clusters and each cluster has dozens of controls in it. I want to go through all the array clusters and change the value of a specific control. Right now, I am using the value property node of the array to get a 1-d array of clusters, looping through it, unbundling each cluster, change value of one element, bundling it back into a cluster, and then giving it back to the array using the value property node again. This works fine but maybe there is a simpler way to do it. With the current method, it is probably using more RAM too because it has to copy all the data.

    (Please always attach an actual VI. It is very difficult to troubleshoot or edit a code image. )
    Anyway, your use of value property nodes is completly misguided here, they just introduce additional overhead and complicate the code! Why???
    All you need to do is (1) read fom the input terminal, (2) modify the array element using "replace array subset", and (3) write the result to the output.
    If you want to also write it back to the control, use a local variable.
    (Depending on the rest of the code, you might also want to keep the array of clusters in a shift register.)

    Title: New Service-Oriented Architecture Patterns with Enterprise Grid Messaging
    Abstract: Messaging systems are essential in enabling the flexibility and loosely coupled nature of a service-oriented architecture (SOA). Oracle WebLogic Java Message Service (JMS) includes new pub-sub capabilities that make architectures more adaptable, allowing message producers to be ignorant of who is the consumer of a message or how many consumers there are. It also enables easy scale out and dynamic adaptability through clustering and message-driven bean (MDB) enhancements, all while still guaranteeing strict message ordering. This session will outline new JMS capabilities and show how they enable new designs with Oracle WebLogic Server and Oracle Service Bus.
