• distinguish between the indicator and controls using property nodes

  How can I distinguish between controls and indicators property nodes?

  I find that the controls and lights on the Panel before all come from the same class... a digital control and a digital indicator share the same properties... I am trying to find a way to distinguish between the two.  I would like to be able to analyse a reference VI pull only the references to the "controls" or "indicators" on the front panel... but when I try this, I shoot all...

  Although I found this case a knot of property ' control value: get all ' referral of VI, I can choose between only indicator or only the values of the controls... it's close to what I want, but instead, I like to shoot only the references to the Group of the "indicators" or only the references to the groups 'controls '.

  does anyone know if there is a simple way to do this?

  Thank you very much!

• OK the property button (LV7.1) cluster node

  Hi people,

  I already found a solution to my problem, but I was wondering if someone could put a logic to it.  I created a group of Boolean values with buttons OK because I wanted to use custom text labels, etc.  When I unbundle the cluster, I get the Boolean desired.  However, when I created a property node, the value was the variant - makes no sense to me.  If I wire the property node to a conversion of the VI Variant (with the Boolean type), the output of the property node suddenly becomes Boolean and stays that way when I remove the conversion VI - makes even less sense.

  Why OK buttons are somewhat different from other Boolean when used in a cluster?

  The fix that I went was to create a bunch of LEDs square with text, turned in the controls and then put them in a cluster.

  The property node was a variant because the 'OK' button is a type of lock. You shouldn't read/write locking type buttons programmatically, because a race condition is inevitable. Your question didn't concern the cluster.

• Formatting a string within a Cluster

  Hey people,

  I have a strange problem. I want to display a string with formatted text in a particular way. I went through the link that talks about the formatting of a string (http://digital.ni.com/public.nsf/allkb/6BD344ACA4DEE20A8625692700737E16).

  The problem I encounter is that I have a control that has 3 channel indicators placed within a cluster. I can perform data management/updated but not able to create a property for the indicator of specific string node in the cluster control that should display the text with specific formatting.

  Is it completely the wrong approach, or can it be reached somehow?

  Thanks in advance, Abel.

  You go about it the right way.  You just need to get the property node bound to the right component.

  

• How do I change the list box within a cluster

  I have a cluster with multiple controls in it. One of them is a combo box on which I need to occasionally change the items to the breast. If the drop-down list box out of the bunch, I could easily access 'Strings []' property of the combo box. However, when inside of the bunch, I don't seem to not be able to get this property. In the excerpt below, the drop-down list box is the control at index 1. I get out of the reference to this control, connect it to a 'property node' and the 'Strings []' property is not found.

  Does anyone know how to fix this?

  

  Hello

  Take this simple way, create a node prperty for the cluster that you have, right-click on the prperty node and select link to, browse lists void until the drop-down list box. See attachment.

• Bytes to Port property node. When to use and when not?

  Hi all

  Ive frequently used bytes to port property node performing bed series and have not experienced any problems.  I've heard mixed on this subject reviews and I would like to know when to use and when not to use it.

  Thanks for any input.

  I will start by when it should not be used.

  When there are (as readable) ASCII data to come through and it is separated by a termination character.  Select the stop character and read more bytes than you ever expect a given message.

  When there are binary data, but a protocol where you know clearly how the message package is put in place.  In this case, you want to disable the stop character because any octet can be given legitimate and be interpreted as the stop character.  With these protocols, if you know the message is always X bytes, read X bytes.  If the message is of variable length, but the Protocol is set to tell you low for a long time the message is, and then make partial readings.  So if each message starts with 2 bytes that says follow X bytes.  Then read 2 bytes, which converted to a number, then read this number of bytes.

  When to use:

  The only time will really use bytes to the port is if you use a terminal of the installation type.  Just enter and display on-screen what never happens happened at the port since the last time it was read.  When you don't care where are message breaks.

  If you use bytes to the port and care message breaks, then you're obligated to all your new message concatenated to a string, you store in a shift register and each reading analysis through data to determine if you have a complete message and valid.  If you do not, do nothing and go back and read more.  In fact, you will need to run through the chain of data several times in a row before coming back to reread in the case where the message ever resulted in a single reading packets.

  The vast majority of applications falls into one of the above situations.  The last situation is not as common, and if you use bytes to the port with a system of e-mail that has defined a defined protocol or packages, you do a job more in programming to maintain a software buffer of data as well as the hardware buffer to the serial port.

• used in a Subvi LabVIEW property node

  I have a group of Boolean control front, I want to minipulate the visibility and color (4) in a Subvi.  I created a Boolean refnum cluster and spent by them in VI.  In VI, I created a group of CTLRefnum that I used as entrance pole.  In the Subvi, I am able to control the visibility through the time property node, but the Color property node (4) does not appear as a selection in the Sub - VI.  Any ideas on how I could control the colors in a Subvi.

  Hello HEJ@WR,

  Looks like you may have thrown your refnums Boolean to more generic control refnums - as the Color property is specific to Boolean values, you will need to ensure that you are now the reference type.  Visibility is a property more generic that applies to all types of controls. Refer to this article for more information on casting refnums:

  LabVIEW Help: For more specific class function

  http://zone.NI.com/reference/en-XX/help/371361H-01/Glang/to_more_specific_class/

  LabVIEWWiki also has a very good discussion of types refnum and properties specific to the class here:

  Also - if you set the example code showing what you're trying to do is much easier for other users of the forum help!

  Kind regards

• Problem with the Value property node (MacOS)

  Insofar that I tested it, the nodes of property Value (and value (signalling)) do not work under MacOS: value property is a Boolean value, the value (signaling) as a cluster (width, height).

  Even with the Boolean controls, the node does not work.

  Not such a problem in LV 8.6.

  Am I missing something? Is that some 'of use' ? Or just a bug?

  This looks like some sort of problem of indexing with the nodes property as somesort of corrupted installation.  What happens if you just delete the property node and recreate him?

  I filed a digital control and looked at the context menu of the list of the nodes property.  Below value and value (signs) are Visible (which would be a Boolean value) and Xcontrol, that when you bring through the submenus, the first choice is container bounds, a cluster of Width and Height.  If these 2 types of data which are located 2 below in the list match those you found.

  What happens if you take another node in property a few elements upwards or downwards in the context menu?  Fact is happen for other properties, and if so, are thereany properties who agree?

  Here's what look like my property for a digital nodes and I draggged the box up and down to show the natural order of the nodes property.  Notice that I have script installed, so there are a few other nodes property (and the blue box at the top) you may not have.

  

  PS. Verify you the signature.  Kudos button is now moved to the left since the update of the forum.

• Why property nodes are not accept input?

  Well, this one is driving me crazy.  I have a Subvi, which contains a string indicator and a drop-down list box, as well as a few buttons on the front panel.  My problem is that when I run the program (in LabVIEW, not an exe file) sometimes the window Question (the light) accepts the string and updates the property of Caption.Text, sometimes it doesn't.  At the same time, sometimes the answer box (combo box) accepts the Bay of cluster in it is StringsAndValues well, sometimes it doesn't.  They both either work, or they do not.  Never a problem with accepting Question window indicator string.

  The block diagram:

  

  Here is an example of the code powering the Subvi.

  

  I don't get any kind of error message.

  Sensors at the entrance of the property offending nodes indicate that the correct data are happened to them, it is just 'ignored '.  Once it starts to spoil, it usually continues to do.

  It seems that the only way I can get to behave correctly should quit LabVIEW, and then restart LabVIEW and run the vi.  Then it will usually works a few times until it starts to work.

  (Win 7, LabVIEW 9.0f3)

  Thoughts?

  What is the source of the wire that goes into your sub - VI Q & A mistake?  Is it possible that you have found errors on this thread?

• Make items within a cluster (in) visible by a Subvi (from LVOOP?)

  Hello

  I would like to know how it is possible to make elements inside an invisible cluster, using a Subvi from LVOOP.

  The description is in the main program, the internal operation is explained in the Subvi.

  Her to give a larger program a better overview. But I don't know how to do it.

  Create a reference instead of a property node.

  Pass this reference to your Subvi and use nodes of property to the rear on the reference that the sub - VI was adopted by the high level VI.

  You can review the images that I have in my "GUI_Controller" Albumn found here. If you click any of these images, it will take you to a page with an image more large and which includes a link to the thread where I spoke at the origin of these images under the model of design GUI_Controller (a form of Action Engine).

  It is apreview of what you will find in this Albumn.

  

  If you post stuff a few photos more (thanks!), so we can take a pic.

• property node

  HI (sorry for my English) I have the problem of monitoring:

  I have a vi that makes measurement it download a cluster with inside some indicators of number and a photo, I create a property node and a control for the cluster reference.

  In my main vi I create the same cluster and I join with my vi measurement using a command reference.

  the problem is... as vi dynamically change the node properties of zoom factor, left and top of image origin origin. I would like to know how to do the same thing for my core related?

  Thank you

• How the index data are managed within the cluster?

  Hello
  
  We are evaluating the consistency.
  
  Regarding indexes, am I right in thinking that the data in the index are stored in a (managed internally) cache on the same node that the attendant at the following indexed values? I'm not interested in getting the data in the index, but rather just to understand how the data in the index itself are stored or processed within the cluster.
  
  So in a 2 cluster node where an index is applied to a distributed cache that has only 2 entries, will there be a key cache on each node 1 {binary,} to enter key where the key points to the value that is stored on this same node? In other words, I'm sure that the index data to be spread out in the cluster in the case of a partitioned topology?

  Hi Peter,.

  up to 3.4.x index have been supported only on partitioned topology, and Yes, the index on each node contain only the data corresponding to the entries that have their main copy on this node (referred to as entered local subsequently).

  The indexes are not stored in a cache, but they are managed under the information that maintains consistency in terms of backup (the map that contains local entries).

  The indexes are in 2 parts:

  -index to the front: this is a mapping of the cache key in an internal representation (Playback key card in the future) the value extracted with the extractor used to create the index of the entry to membership of the cache key (value extracted later)

  -reverse index (aka. reversed card): this is a map of the value extracted from a backup set of the keys of the map of entries which we extract the index key reversed with the extractor used to create the index

  The index can be sorted, which means that the index reversed a SortedMap (sort order is the order of the extracted values)

  Let's see an example. Assuming you have the contents of the following cache within a particular extension storage node:

  A--> Object (PositionX = 5,...)
  B--> object (getA = 3,...)
  C--> object (getA = 3,...)
  D--> object (getA = 4,...)

  The index forward in this node will contain:

  Binary (A)--> 5
  Binary (B)--> 3
  Binary (C)--> 3
  Binary (D)--> 4

  The reverse index will contain:

  3--> {Binary (B), Binary (C)}
  4--> {Binary (D)}
  5--> {Binary (A)}

  Where Binary (...) designates the internal representation (binary) of the... object.

  If the index is not ordered, then the order of iteration over the entries in the index reversed are not deterministic.

  If the index is ordered, the iteration of the entries into the inverted index will be as stated above. Also, you can convert the SortedMap inverted index in order to have the very useful headMap and tailMap and firstKey and lastKey methods.

  I hope this helps.

  Best regards

• Graph plot legend colors Signal not updated when mixed with the property node

  Hello

  We try to put the colors of the trace of a graph of Mixed Signal using a property node. Although we can change the color of the data in the field correctly, the colours of the plot in the legend do not change until some apparently unrelated operator action is performed (for example, to resize the window or by double-clicking a field name).  Waveform to XY charts don't seem to have this problem.

  Anyone know a work around?  I think I saw a similar topic on the forums earlier, but I'm sorry that I am unable to find it now

• Error: The property node (arg 1) in .vi VISA set up a Serial Port (Instr)

  Hello

  I've seen people once they have gotten this error, but none of them really apply to my situation.

  Right now I use LabVIEW example code to read from a device manufacturer. This device is connected using a Tripp Lite USB adapter series (http://www.tripplite.com/en/products/model.cfm?txtSeriesID=782&txtModelID=2430) for the connection from the PC to device with RS232. The adapter works fine when using the software prepared in advance (not LabVIEW) given by the manufacturer and the COM port is seen by LabVIEW. When I run the program, I get the property node (arg 1) visa set up a Serial Port (Instr) .vi (I've also attached the VI but it's a standard VI I got of LabVIEW). I get this error despite the fact that I use the same COM port, who has worked with the manufacturer's software.

  I have attached manual of Protocol RS232/debit BUS (not sure if this applies) that requires the device. The device is a mass flow controller whose operating instructions is: (http://nemu.web.psi.ch/doc/manuals/device_manuals/Bronkhorst/917023--Operation%20instructions%20digi...

  I'm using LabVIEW 10.0.1

  Any help is appreciated

  Try to restart the PC and then try the LV version before trying other software.

  I have seen thrid party serial interfaces work on the first try but fail when you switch to another application. It was as if the pilot did not know that it was no longer the first process.

• Issues related to the cell property node: Position Active for a table control

  Hello

  What determines the Position of the Active cell in a table control property node? I have this in my code and display the value of an indicator on front panel. The displayed value is always set to 0,0. Help for the property node says it's "read - only" so what defines the Position of the Active cell in a table control value?

  Define you the active cell with a property node.  Once you select an active cell, you can do this cell and single cell-specific things, things like the background value color.
