• block diagram window becomes higher in win7 64-bit using LV2011 32-bit sp1

  I have a strange problem and I wonder if anyone has ever seen this behavior. Often, when I go to the block diagram window, it will become the top window that is it is located at the top of all other windows including LabVIEW non-windows! I have to close the VI and really open to fix the problem. I see this on 3 machines, all the dell of m6600 laptops so I think it's maybe a graphics driver issue. Any ideas?
  Thank you
  Michael.

  Tori,
  I confirm that this problem can be solved by removing the Dell Premier color utility that installs with the driver dell put on hardware compatible color first. The question of the window occurs when LabVIEW works so there is some kind of conflict. Anyway, problem solved for me.

• HOWTO call "n" independent instances of 'Decimate (continuous) .vi"without putting instances of"n"of the VI on the block diagram?

  I have a double 2D chart I want to decimate continuously using the ".vi (continuous) Decimate" located in the range of Signal Processing. This VI is set on reentrant preallouee clone because it uses a FGV to save the State of the call to.  What I could do, but do not want to, is having a huge index table and wire 20 + 1 table of DBL to 20 + unique VI instances decimate to ensure that each have their own data space and no 'cross-talk' doesn't happen, then 'picture of generation' all back after the fact.

  I'm almost certain, there is a much cleaner way to do it with only one instance of unique block diagram of the VI decimate using techniques of the call by reference.   I found my way to this link: Preallocated-Reentrant-VI-within-Parallelized-For-Loop that talks about something similar.  After reading pages of four and the detailed help about the function 'Open VI référence' my head is spinning again on what option I want to spend (0x08 or 0x40 + 0x100) to ensure that whenever a slna 2D table come in, each of them is decimated by using the same clone that was used the last time it was called.

  Although the DBL entry 2D array always has the same number of lines, now, it is not always in the future this number and ideal would not force me to create several references strictly typed in VI decimate that will have to change as grows the number of rows in the table 2D static DBL.

  Anyone ready to set up an example VI that takes an array 2D arbitrary of DBL as input, decimating each line using the same clone independent of the "Decimate (continuous) .vi" and outputs the newly decimated 2D Array of LDM?  Assume that each line uses the same factor of decimation and 'Sprawl' set to False.

  Necessity is the mother of all invention and since it upsets me when I read a post that has a similar problem with no resolution, I felt compelled to post mine here.   I'm sure it's better I can do within the current state of LabVIEW.   The only question I have is what happens if I put the call by reference for loop be parallelizable?  That trash completely the nature of 1 to 1 of what I intended?

  

• Can not see block diagram of an auto run VI

  Hello

  I have an old and dirty VI which runs automatically when opened. I don't see the block diagram because when I stop it, LabVIEW stops. There is probably this function of 'evil' LabVIEW to stop at the end.

  Is there a way to avoid this behavior?

  The VI wrote some time in LabVIEW 7.0.

  Thanks for the help!

  Drag in a BD to another VI and double click on it from here or...

  Find one of the SCREWS he calls and break first or

  There may be other ways...

• Corrupt the VI block diagram (try to view the BD accidents LV)

  The attached corrupt version 2010 VI in the room is '8810A control.vi.'  I put work a few days into it, so it would be nice to get it back.  I can open it fine to display the front panel.  When you try to view the block diagram, an outline of the BD window appears and freezes LV.  Usually, after a few moments, LabVIEW itself disappears completely.  No error message; no sign of it in the taskbar or any where.  I tried to save the VI to a previous version, but LV will receive an error.  In trying to "Double hierarchy to the new location", I get a popup saying "LabVIEW: file generic i/o error.»  I then did a copy of VI, open and tried to delete everything from the face before completely.  Still can not go to the BD.

  I think that what caused the error was when I accidentally clicked my mouse button that I arrived to move the cursor quickly through the BD of this VI.  I couldn't tell if it hit or moved something on the comic.  I don't remember for sure, but I think that at this time there LV froze and I had to kill him and restart.  After happened yesterday, I moved on to work on other screws which have not been affected.  I guess I'll have to recreate (because I had not yet created backups).  in the future, I hope that I can remember save projects at least twice a day.  I've used Mercurial and it works well.  Hard lesson learned.

  Try this.  I saved to LV9, opened with LV9 then did a cleanup of comics.

• How to set a menu of VI function to generate a copy of it self when it is move and dropped on the block diagram

  Is any way to put a VI that I placed on a palette in the menu functions to create a copy of it self when I place it on the block diagram?

  My example is as follows. I create a palette for a messaging configuration. The 'send message', 'message' and so forth will work normally with just called when necessary. But 'Create queues messge' must be specific for each instance, because I'm going to create a different number of queues each time I use it. (See system messages in queue OR for the "Continous Measument and Logging" model).

  So every time I drag and drop that VI (Create message Queues) in the palette, I want that it ask me where I want to save the VI.

  Is this possible?

  See you soon

  There is always the file-> new... that opens a new window.  You can have your models in this window by putting them somewhere (I can't remember where at the moment).

• exec Subvi system. Cannot access the positioning block diagram

  OK I'm back!

  My first question is that for some reason any I can reach is no longer here the files for you all to see...

  Second and more to the point, how can I know the exec.vi for open system where I want it too when the block schema access is password protected and I can't seem to make the nodes property for the vi either.

  I use this vi to call the OSK (on screen keyboard) for touchscreen.

  I have an example to show, but see number one...

  It seems to me that you want to position the osk and that means access to the block diagram is irrelevant.

  To position the program that you are a beginner, try this.

• Block diagram of... block diagram

  Hi, I need your help. IM the wrong person for this post, but I have to do, so I depend on your help. I need to explain how LabView (pasted below) program works, but I don't understand it myself I would like to ask if someone can create a simplified block diagram of the pattern-block LV I paste it here. I appreciate all the help and please take considaration I am short on time

  https://DL.dropbox.com/s/yd10z7yorxvbzux/LVdiagram.jpg

  It is a counter. Meter of photons to be exact.

  Hi, Rodolphe,.

  I will try to explain briefly what is this application:

  Following materials may help you understand the underlying concepts:

  http://www.NI.com/PDF/manuals/371022k.PDF

  It is the manual of series M - chapters 6.7 and 8 explains how digital lines, meter and what is a PFI.

  When you open the block diagram of your application, you can see several branches ranging from left to write.

  The first one on the top is to create a path to a file. This path will be used to write data to a binary file. The data represent the number of impulses which can be counted as edges rising a signal connected to the meter to 1. This information CA be read if you follow the logic on the second branch from left to right, where the first VI is CI INT edges (edges of counter), and it will count up, on a rising edge of the signal connected to CTR1.

  Later, there is another task created for counter 3, that generates impulses. The pulse seems to have 10uS length and 50% duty cycle. The signal generated by this counter is used as sample clock for measure and 1 meter. In addition, the same meter signal 3 will be used by 4 meter from the digital dashboard and create a clock which will clock the timed loop. Basically, the frequency of the timed loop is given by the task on 4 meter which counts pulses generated with meter 3.

  The 3rd branch from left to right, creates three tasks on three outputs digital: Line 0, 1 and 2 where it is controlled by three buttons F0, F1 and F2. Basically, your timed loop will be a specific iteration, and every iteration buttons will be read and will be updated to the specified digital output above.

  Whenver there is a mistake or the button is pressed, your application stops and closes the binary file and dealocate resources used.

  I invite you to also look in the above manual.

  Best regards

• LabVIEW move things on different computers block diagram

  We have a site here license to my work, and I use several computers to develop and deploy our test code. However, I discovered that between computers, often things move on the block diagram simply by opening them on different computers. Mainly text fields. We have some text fields next to rows of a table of block diagram that are alliged with the lines of table on a single computer, while the same without code change when opened on another PC, all text fields are compressed vertically so that they no longer align with the rows of the table. This could be the cause, and is it possible to fix it?

  Thanks for the replies. It is the size of the police which was the issue. However, although I have tried to change the default Application font size (by the "default font" settings of "modification of the characteristics of text") to match the computers that had "correctly" it was not solved the problem. I finally realized that I had to change the police system from the Options > environment > fonts > menu fonts application of the front screen of "Open/create", then completely restart LabVIEW. Problem solved.

• LabVIEW block diagram icons became invisible

  I'm a bit of a loss here.

  I worked on a fairly large vi of higher level for a while when suddenly several vi system developed display problems.  In particular, all the screws of the FPGA module no longer appear on the block diagram.  They are there, because I can move the properties and thread them, but they are invisible.  Even if I add a new menu, it is invisible.  Is the same for the control on the structure of timed loop block.  The loop is visible, but the controls are not.

  I have attached a picture of a part of the vi that shows what should be a 'open FPGA reference' and a timed loop.  As you can see, the wires are connected and it compiles and works very well, but there is nothing on the screen

  It is specific to this vi.  If I create a new vi and add the same vi they look very well.  As far as I know, I did not change to any display settings.

  Any suggestions?

  Hi Nathan,

  You should be able to get a global position by moving one of the scroll bars.  When you click or drag the scroll bar a small box should appear (right of the cleaning if the BD is enlarged or below the bar of horizontal scrolling if the BD is is not maximized) giving the global coordinates.  If you find that you are outside about 15000 pixels (I don't know if it is a hard cut) are trying to move close to the origin.

  You should not recreate anything.  Actuall you can find the line where the icons become visible.  In a quick test here he looked about 15000 pixels.

  

• Do not see diagram opening of vi

  Hello

  It's trivial, but frustrating. When I opened a vi I see the front panel and then have to press ctrl-E to see the block diagram.

  Can someone tell me if there is a way of opening the vi and seeing the front panel and block diagram immediately?

  Thank you very much

  Is there something special examples OR tutorial?

  No, but there is on the dialogue window. It's a custom window (a VI, LabVIEW, actually) that creates a new VI from a template, and then uses the VI server to automatically open the block diagram.

• Block diagram does not

  When I start my VI, a traditional State Machine, I can't use the buttons on the block diagram toolbar, or probe the block diagram. Nothing on the block diagram is accessible, so I opened each State to a separate VI to see if the problem of monitoring, but he goes. This issue seems to happen only with this particular VI, but I have no idea how to solve it. I am running 8.5. Thank you.

  Seems that my FP was not modal by default, which caused all my problems. Thank you very much to those who have tried to help me.

• New effects of resolution monitors on block diagram

  I recently got a new PC with display quad outputs IT.

  I had new monitors with different resolutions, since the old monitors that I used.

  Everyone noticed when opening old projects on a new presentation available to block diagram to become very different?

  For example, look at the attachment, look how big is the area "Group by name", and how it has consumed all the objects around it.

  

  There is a font size setting that must be set to ' small (default) 100%.  Make sure that it is not defined for medium, 125 or more than 150%.

• Double-click the object of front panel to find the terminal block diagram

  Hello world. I don't know why, if I double click on an object to front panel, labview opens the front tab customize, instead of finding control in block diagrams, which would be the normal behavior, as I read in http://labviewwiki.org/Tips_and_tricks#Debugging.

  I tried to reset the initial Setup by renaming the file LabVIEW.ini, but it doesn't seem to work.

  Do you know how double-click the object on the front panel and locate the?

  Thanks in advance!

  Guille.

  Did you restart LabVIEW after you rename the file labview.ini?

  There is an option (Tools... options...... general façade... 'Open the editor control with double click').

  It always seems to be set in your case.

• What this block diagram?

  What this block diagram?

  Match a VI Modbus Library. But I have because if the block is configured to write multiple coils in the coils because reading is set to 1?

  All this work?

  Sorry if the question is a beginner.

  

  In this block diagram, 'Coils Read' and 'Write multiple coils' are enumerated values (or possibly ringtones of appeal, which is not serious for the purpose of this explanation). Enumerations assign names to numbers, to make them easier to read. The coils Read command is set to 1, the command to write multiple coils has a value of 15. You don't need to worry about this number, however, because the enumeration takes care of it for you.

  The constant cluster containing coils of reading is there just to provide the correct data type (a cluster with the right items). Almost all the elements of the latter shall be replaced by the values of wired in the Bundle to node Name. For example, the value of reading coils is there as a placeholder for any function Code. the actual Code of the function is defined by plugging write multiple coils in Bundle by name.
