How to display updated values in an array of clusters?

Hi all!
I am designing and coding a LabView application. In one of the modal dialog boxes of the application, I have to dynamically create an array of a cluster in the front panel. The array of the cluster is one dimensional. The number of rows of the array control containing the clusters is dynamic, depending on the user input. I have selected number of rows of the array as 4 in the test vi. The number of columns is fixed to 1.
The cluster comprises of two elements - a numeric indicator labeled "Machine #" and a radio button control with three choices. The three choices are "Pump", "Compressor", and "Fan". I am assigning a machine number to the numeric indicator in the cluster during initialization of the screen. Similarly, I am assigning a default selection - "Compressor", among the three choices of the radio buttons of the cluster. This is done for each element of the array.
As far as I can figure out, I am assigning these values correctly. However, I am unable to see the changes on the front panel in the values of the elements within the cluster during the run time. What am I doing wrong? How can I solve this problem?
I am uploading the test vi that I have written till now. Any help is much appreciated. Thanks a lot in advance.
Sincerely,
Aninda

Hi!
Maybe, I forgot to attach the VI in my previous posting. Here it is.
Sincerely,
Aninda

  • How to get updated value at run time in oracle forms

    How to get updated value form oracle database on a field in oracle forms 6.0 at run time if the same form is opened by multiple users and both have get the same maximum value if one commit the record then how other would get that maximum value with out exiting that form...

    This issue is fairly common and Forms handles the situation by displaying the error, "Record has been updated by another user. Requery to see changes." if a user tries to update a record that was updated by another user.
    If your data is in a base table block, you can check before you save by checking the value in the form against the database using the Get_Item_Property('<BLOCK.ITEM>',DATABASE_VALUE). You can compare the value returned by the built-in against the value in the field to see if they have changed. This could be a lot of work and a lot of network traffic if you are checking numerous items in your data block. Forms has a standard locking mechanism that will lock the queried record as soon as a user makes any changes. If another user queries and attempts to change the record locked by another user - they will receive a "Record Locked" message.

  • How to display negative values in a screen field of a screen

    Hi All,
    Please let me know how to display negative values in a screen field of a screen.
    thanks

    Hi Kishore,
    You can do this method. In the screen , create a text field of CHAR instead fo creating an INT4 field.
    I have created a field of CHAR of name say TEXT.
    In the main program,
    declare a variable of the same name ie. TEXT.
    data: TEXT(5) TYPE C.
    In PBO, just assign the negative values.
    It will work.Since there is automatic conversion between character and integer data types, it will work for positive values as well.

  • Setting Values in an Array of Clusters via COM

  • Using DMA to update values in an array

    Good afternoon, 
    I've been running into a few problems with my vi, and I'd like to give a bit of the background information before I ask my questions. I'm using Labview 8.5 and the NI USB-6009 DAQ. I want to use an encoder to control values that are being written to a file for DMA. I found that I couldn't use the encoder as an external clock since the 6009 DAQ doesn't have this capability. So I've been trying to go a differenet route by using a case structure with a True/false statement to allow me to input values from a simulated signal into a write vi (each time the encoder pulses, a value from the simulated signal should be inputed into the write data storage vi). From there, I want to then read those values and put them into an array. So the plan is to have a 10 element array that reads in values from the storage file (just like in FIFO for FPGA). As I continue reading values, the oldest value of the 10 element array will leave the array and be replaced by a new value. 
     Now here come the questions, I'm using the Write/Read data storage vi's and I keep getting errors. First, if I'm wanting to use DMA to read these values am I using the correct vi's, or is there a different route? Also, once I read these values into the array how would I be able to constantly update the array in a descending order from begining to end of the stored values? 
    I'm posting my most recent vi that I've been editing. Also, in advance, thank you!

    Using Encoder as an analog input 10_9_13 - Copy - Copy.vi ‏390 KB

    Thank you for your reply.
    First, I'm ultimately trying to use the array as input into a visual display for a meter (to display the mean of the array). I've been successful (in the past) with inputting into an array by not using DMA and using the Sort 1D Array point by point vi. The only problem is the timing mechanism with the encoder, and you are correct with stating that there is uncertainty with the encoder when trying to retrieve values from the input signal (sine wave). I thought about going down the route of using the encoder as a counter (since I am able to see the counter increase by a single digit with each pulse).
    My question would then be how to control the case structure with a counter input? 
    I'm posting both my setup with the Sort 1D Array Point by Point and the simple vi for the encoder as a counter. My idea is to try to merge the two and have the counter control the case structure. 
    Is there a way I can do this?

  • How to set the value of an array element (not the complete array) by using a reference?

    My situation is that I have an array of clusters on the front panel. Each element is used for a particular test setup, so if the array size is three, it means we have three identical test setups that can be used. The cluster contains two string controls and a button: 'device ID' string, 'start' button and 'status' string.
    In order to keep the diagrams simple, I would like to use a reference to the array as input into a subvi. This subvi will then modify a particular element in the array (i.e. set the 'status' string).
    The first problem I encounter is that I can not select an array element to write to by using the reference. I have tried setting the 'Selection s
    tart[]' and 'Selection size[]' properties and then querying the 'Array element' to get the proper element.
    If I do this, the VI always seems to write to the element which the user has selected (i.e. the element that contains the cursor) instead of the one I am trying to select. I also have not found any other possible use for the 'Selection' properties, so I wonder if I am doing something wrong.
    Of course I can use the 'value' property to get all elements, and then use the replace array element with an index value, but this defeats the purpose of leaving all other elements untouched.
    I had hoped to use this method specifically to avoid overwriting other array elements (such as happens with the replace array element) because the user might be modifying the second array element while I want to modify the first.
    My current solution is to split the array into two arrays: one control and one indicator (I guess that's really how it should be done ;-) but I'd still like to know ho
    w to change a single element in an array without affecting the others by using a reference in case I can use it elsewhere.

    It isn't possible to get a reference to a particular element within an
    array. There is only one reference to the one control that represents
    all elements in the array.
    While it may seem better to use references to update
    an element within
    an array, it shouldn't really be necessary, and it can also lead to
    race conditions. If you write to an element that has the
    possibility of the user changing, whether you write with a local, a
    reference, or any other means, there is a race condition between the
    diagram and the user. LV will help with this to a certain extent,
    especially for controls that take awhile to edit like ones that use
    the keyboard. In these cases, if the user has already started entering
    text, it will not be overwritten by the new value unless the key focus
    is taken away from the control first. It is similar when moving a slider
    or other value changes using the mouse. LV will write to the other values,
    but will not rip the slider out of the user's hand.
    To completely avoid race conditions, you can split the array into user
    fields and indicators that are located underneath them. Or, if some
    controls act as both, you can do like Excel. You don't directly type
    into the cell. You choose w
    hich cell to edit, but you modify another
    location. When the edit is completed, it is incorporated into the
    display so that it is never lost.

  • How to get updated values from the loops while they are running

    Hello,
            I am having difficulty solving a very basic problem, how to access the updated values from the 'FOR loop' while its running?  Basically, the VI  I am currently working on calls two sub VIs. Each sub VI has a for loop, and both VIs may or may not run for same number of iterations. My goal is to read the values at each terminal inside the loop of both sub VIs, in the Main VI. I tried to achieve it using Global Variables, but in main VI it displays only the last iteration value from both sub VIs. Could anyone please tell me whrere am I going wrong? Is there any other/better way to achieve this.
    I appreciate any input on this issue.  
    Kudos are (always) welcome for the good post. :-)
    Solved!
    Go to Solution.

    Dennis,
                In attached VI, I can see the values changing in the sub VI from the main VI with the numeric indicator whose reference is passed on to the sub VI. Now if I wanted to store or use those values how do I do that? I tried to chnge the indicator to control and read from it (in the attached VI) , but the the indicator updates only once. Tried to create a property node and read the Value from it and it didn't work either.
    Thanks in Advance!

  • How to get the values of an Array using JSP Tags

    Hey guys,
    I need some help. I've splited a String using
    fn:split(String, delim) where String = "1,2,3,4" and delim is ,
    This method returns an Array of splited Strings. how do i get the values from this array using jsp tags. I don't wanna put java code to achive that.
    Any help would be highly appreciated
    Thanks

    The JSTL forEach tag.
    In fact if all you want to do is iterate over the comma separated list, the forEach tag supports that without having to use the split function.
    <c:set var="list" value="1,2,3,4"/>
    <c:forEach var="num" items="${list}">
      <c:out value="${num}"/>
    </c:forEach>The c:forTokens method will let you do this with delimiters other than a comma, but the forEach tag works well just with the comma-delimited string.

  • How to display(binding) values in the table from more than one node?

    Hi,
    I have two nodes (TRIPS & AMOUNTS)in the context. How to bind these values into the table control?
    When i bind second one, first one is getting replaced.

    Hi Mog,
    Of course it is possible to create a table from attributes of more than one node, and in some cases this is still necessary, but you have to do this the hard (manual) way.
    If you have a table control, have a look at the properties and the elements belonging to it.
    First of all, there is the property "dataSource", which binds to a multiple node (let's name it TableRootNode). This means that for each element of THIS node, one row is created. In each row the data of exactly one element of this TableRootNode is displayed.
    Then you have columns in this table. Inside of the columns there is a header and an editor. The editor is the interesting part.
    Normally the primary property of this editor is bound to an attribute of the TableRootNode. Then everything works as expected. If it binds to an attribute of a subnode (SUB) of TableRootNode, then in row i the data of the subnode of the i-th element of TableRootNode is displayed. There is no need for SUB to be a multiple node, but it must not be a singleton.
    If you bind a property of the editor to an attribute, which does not lie in the subtree of TableRootNode, then you will see the same value in each row.
    Now it depends on the structure of your context. Take the node, which is relevant for the change in each row (I assume it is TRIPS) and bind the table to the node as you are used to. Then for each additional column, you have to create a new column in the tree, create a new header element with a title and a new editor (e.g. textview or inputfield) and then bind the right property of the editor to the corresponding attribute in node AMOUNTS).
    If these 2 nodes do not have parent-child-relationship, the tip to create a new node, which consists of the attributes of both nodes is the only solution.
    Ciao, Regina
