• 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!

• A witness flashing without property node

  Hey!

  I am familiar with property node flashing but I want to do a Flash of the LED due to a timer interfering with a cycle FOR I almost did a VI that compares the value of the timer value y. When the value of the timer is larger than y, then my LED should shine. The timer value is smaller than y then it should turn off. Something wrong, perhaps someone could help me.

  I came up with this real quick. I'm sure there are more elegant ways to do this.

  

• Property node enabled even if it is removed from the diagram

  Hello

  I messed around with the property of one of my tests node and when I had finished and removed the property node the block diagram it's always my control blinking.

  How can I stop?

  The option to enable State is not possible in mode of property node. I turn off and active in gray.

  Thank you.

  To stop the flashing:

  1. Create the node property flashes again.
  2. He lead a constant False .
  3. Run your VI once.
  4. Remove the property node.

• Property nodes are all seriously affect performance

  LabVIEW gurus,

  I'm running continuously in some serious performance degradation by using nodes property to update the attributes of the objects of the public Service. A classic example is attached.

  I have 8 plots XY which are fed 600 SGL tip all the 200 ms - one very modest flow. Each plot is a dynamically instantiated .lives placed in one of the 8 sub-panels in a container of VI. The VI container also acts as Server data for charts, each of them sending their data in the queue for their own unique item. The entire architecture works great (~ 4% CPU load, see attached picture) until I by updating a node property to display the value of the value of the cursor there. When I activate the property node 'Caption.Text' of the XY graph to display the value of the slider, the CPU usage rises to more than 30%.

  As an aside, I'm developing on a platform of 2.1 GHz dual core with 4G memory with LV8.5.1, and the target machine is not nearly as strong. That's why 30% CPU on my plant is a problem - it essentially brings the target incorporated to its knees.

  I've included an example VI to run on your machine. Think of it as 'representative' of my biggest problems. The VI series update the CPU without the legend about 10% and 20% with updates of the legend.

  Finally, I tried to put the screws in the system of execution of the user interface. I also tried to postpone Panel updates, but this actually slows performance.

  Best regards

  With captions

  Use captions only for noncyclical display. With the help of a text indicator should solve the problem.

• 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.

• property nodes, controls reference

  Hello

  I just want to know what is the difference between the two approaches below to see in the excerpt. Both work. What is the real role/reason for the conversion? Both are OK to use?

  Thank you!

  

  It depends on what you are feeding into it.

  If really you are breast-feeding refs control CREDITS, then the TYPECAST does nothing.

  If, however, you are breast-feeding in mixed references (Boolean, string, I64, cluster), then the TYPECAST throws everything in GENERIC refs.

  I would NEVER recommend doing this, however.

  1. If all you do changes the ownership of persons with DISABILITIES, and given that the DISABLED property is common to all controls (i.e. Generic), generic Ref is fine as it is.

  2 - If you need to cast, use the MORE GENERIC TYPE CAST or the SPECIFIC TYPE CAST MORE and let them tell you (error) if there is a problem.  The TYPECAST will take whatever you give him and spit out a reference, but it will not necessarily legitimate.

  Using the MORE SPECIFIC TYPE CAST is useful when you get an array of controls from a cluster, but you KNOW they are all list boxes, then you can throw in a type of list box and do things specific to the ListBox on each of them.

• How to change the constant value for the property node "Disabled"?

  Hi all

  I enclose one vi example of what I'm willing to do. It happens during the event for "left selectorrogrammed 1: changing values.»

  Basically, I created a property to a Boolean LED control node. Once clicked, I'm eager to turn it off so that the user cannot change the value (I have a reset all button for use on that).

  I created the node property for this control for disabled people.  When I'm in the block diagram, I change to write mode.

  I rt clicked on it and said: ' create constant ", he does.  However, the constant comes each time as "Enabled". I tried clicking on this constant and looking through all of that property, but I can't find a way to scroll the values or set the value of this constant to "Enabled" to "disabled."

  I see where you can change the elements of this constant... but I guess there is a way to switch this constant to the value you want... any suggestions?

  Thanks in advance,

  Cayenne

  To change a constant value, your cursor must be in the mode 'finger '.

  You can select this option in holding down the SHIFT key and right-click on the diagram - then select the finger.

  Another way is to put the automatic selection of tools:

  Tools > Options > environment > lock automatic selection of tools

  With this option, LabVIEW will choose the tools for you.

  Play with him a bit to see how it works.

• Error: The property node (arg 8) visa to configure the Serial Port

  I'm trying to control 8 USB to R232 via a HUB of 10 ports Tripp-Lite (model U222-010-R) and do not have consistent results.  Just after rebooting my computer, I have no problem in running the following program: (I tried to download the VI directly but without success, so here's the extract)

  

  I made sure that the COM ports that I select are that one is available on both the Device Manager and in the NOT-MAX.  But after awhile, it does not work or if the HUB is unplugged and replugged in (even if the names are correct and up-to-date in devices and NOR-MAX Manager) I get the error code "property Node (arg 8) visa set up a Serial Port (Instr) .vi" I want to be able to see these ports consistantly more without having to restart my computer all the time.  Is there a better Setup for this? The previous installation of the computer has a PCI card for it and we have not had any problems with the code, but are facing problems with our upgrade.  The old computer ran Windows XP and had cards PCI and the new computer that I am using a Windows 8 and the USB HUB.  Thanks for any help you can give!

  Mr says:

  Jeff,

  It is a one off lines from specifications Tripp-lite:

  -On bus power, 500mA from the USB 2.0 computer port is shared between hub ports

  This would be in support of what I need or not necessarily?

  No! That's the 50mA by port not 500mA.  an order of magnitude full powered USB (if you want reliable - if you want real problems which appears irratically each time only and is a headache to track down which would)

• RT - property node error 1055

  Hi all

  Currently I develop an app RT on LabView 2014 SP1 which consists of three parts:

  • A PC vi that read the data and sends it to the target of RT;
  • A RT vi running on the CRio-9074 which receives data, convert it to current values and send it to current output modules. It also sends PFGA a number of pulses must be generated.
  • A FPGA target that receives a number of pulses to be generated and then do the work by a module ttl

  Things will work perfectly when the RT vi cover is open on the PC. This happens when I enter debug mode simply run the vi RT of the Project Explorer.  The problem started to happen when I tried to run the program without the RT vi front open. After some research, I discovered that the application of the RT was generating an error 1055 in a stream property node. The strange thing is that this does not happen while the RT vi façade is displayed on the PC!

  Althouth it seems to be a problem known as I found on the Web site of NOR, it is not clear for me, how do I solve the problem. Should I just close the RT VI, open it, close the vial, compile and deploy it finally? Well, if it is that means that workaround, it did not...

  537230 Return

  Changes to the VI with dynamic references breaks VI with the error-1055 the Node property When a VI deployment that allows to get a dynamic to refer to a control on a x 64 Linux target in real time, the VI deploys successfully. After you make a change to the VI, error-1055 is thrown from any node property is trying to access the dynamic refnum. The error says "error-1055 has occurred to the property node...". » Workaround: Close, and then reopen VI. Report version: 2014 SP1    Solved Version: N/A    Added the: 23/07/2015

  Thank you all for the help. I use a few cards in the RT vi and was the use of the nodes properties to clear the history. These cards are only for the control of the application while it is still in development, and it worked fine while I ran the RT application with its façade exposed on the PC screen. At the moment I leave be executed only in the CRio, he started planting and throwing the error 1055. I removed the nodes properties because they are not indispensable and everything works fine.

• Visible property node question

  I need to enlarge the various controls on my front and disapper with function of what is done is there an easy way to do a lot of different things appear and disappear without creating a node property for each individual. His slow me down a little during the execution and the sound also make my huge primary VI.

  Try to create a table of references to the things you want to make visible/invisible, and then pass this array in a loop with a property node inside. This should make you save a lot of space to block diagram.

• 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!

• [] DisabledItems property node

  Hello

  I use a couple of controls of the ring to allow the user to my GUI to make certain choices.  I want the options available in a ring of control depend on the selection made using it.  I do this using the [] DisabledItems property node.

  See the attached example.  The selection is made by using the 'Commission' control affects items that are disabled in the "Image Type" control.  However, it is still possible for the user to select an invalid option (which would cause significant dysfunction of the overall GUI) indirectly.

  For example, in the attached VI, select 'CBS' in control of "Board", then select "Initial start-up" in control "Type of Image.  Then change the jury selected in "ACB".  The type of image remains as "Initial Boot" (although gray)-a scenario that is not allowed.

  Is it possible to prevent the disabled items in remaining selected?  Otherwise, is it possible to report when a disabled element is selected, so that the user can be prompted to change their choice?

  Any advice greatly appreciated.

  Dan

  I find that the Structure of event helps out a lot in situations like this.  See my attached VI... in the case of change of value for the control of the Board of Directors, I see if the current Type of the Image is one of the newly disabled... and if so, I change its value (in my case simple, I put it to "Operational" since this seems to be a correct value for all types of room).  I hope this helps...

• Visible property node tab Page work does not correctly

  I do a vi in which we have a tab with 6 pages control and to move from one page to the next there is control of ring with option for each page to page 1 (page 1 is the default value), at the same time only a single page is visible, so that we can move only through the control of the present ring on page 1 and return to page 1 of all the other pages there is button "return" on all other 5 pages, everything works well for 5 pages, but when after going to page 6 and then if I press return button instead of going back to page 1 program crashes and one more thing I've noticed is after that judgment of the program on page 6 becomes the default page (which is page 1) I know not why it is past.

  I enclose the snippet of code that runs when I press go button "back".

  one more thing I get here is when I checked the program through the execution of the step, the last property node (page6) that runs first, after that it goes to the first node in property, then he goes in order, this also I want how is what is happening.

  It would do the same thing as your code?
