• Cannot insert field or paste into the existing local Variable (Boolean container)

  Cannot insert field or paste into the existing local Variable (Boolean container)...  TestStand 4.1.

  It is very strange, especially since I've done it before.

  'Paste' and "insert field" selections are grayed out and disabled in the context menu.  I tried everything I could imagine and tried various combinations of positions.  I'm sure it's something simple, bu redicoulously, I can't find the redicule to solve this annoying problem issue.

  The local variable is a container of Boolean.  It has 90 elements and I need to add one more.  I can not change / rename or do something with this Local.  Must be karma (for those who know me in the LabVIEW forum).  Usually, you do a right click, insert field and that's where...  Not this one...

  Anyone seen this before?  Closing and re-opening TestStand doesn't change anything.  There is a collection in LabVIEW that feeds the local section in TestStand.

  It is a container of data custm type.  To change flags are ok (edit is allowed).  Can't think of any other valuable information...

  He finds...

  It should be edited in the Data Types...  It was not automatic after reloading the prototype of LabVIEW.

  I knew it was something stupid that I didn't...  I became close... but had not sought far enough.

  I was looking at the range of Types, but not in the file of the sequence...

  

• How to replace the more local variables

  It seems that I had far too many local variables in my VI.  Is there a way I can replace it with a database server?

  
  

• I can do something that would cause all the new sequence files to have the same local variables?

  I would like to add local or drop some variables global to all the new sequence files I create. I was hoping that I could simply add the variable to the process template and make it appear whenever I created a new sequence or in any order who have used this process model, but it doesn't seem to work.

  Does anyone know a way to do what I'm doing?

  Thank you.

  Skeptic,

  If you use TestStand 4.0 and later versions, you can create a sequence model by adding a sequence selected in the models pane of the TestStand sequence editor.  You can then use this template to create all your future movies.  Once you configure the model you like you will be easy to reuse this sequence skeleton again.

• Cannot write to the TEMP environment variable path

  I am trying to install PostgreSQL 9.3 program and I get this error whenever I try to run the application. Please give me a solution.

  It still does not work. Another error occurs when I try to add the new value (C: \ Windows-System32------vbscript.dll): write new content of the value error. Thanks anyway. I hope that I managed to install. Or perhaps there is another solution.

  Hi, Roxane, I had the same problem as yours. This is how I fixed it

• By the way the local variable to a default module

  I use LV 8.6 and TS 4.1.

  I made a custom step Type where I specified a default Module to run and I created a substep VI Edit that the user can move the entry to the default maodule.

  If I pass a value it is working properly. So, I want to pass a local variable, so I have a button in the edict Vi, which displays the property browser dialog box I get the name of the selected local variable. How can I pass the local variable to the default input module? (The value of the local variable is installed during the execution of the sequence).

  Thank you.

  Max.

  Hello

  Yes, I see what your problem is.

  If I am proving a means of suppling a variable as a fixed value or a search string then in my step type I organize the property as a container that contains two properties, one to hold the value and one the search string.

  If you don't have what it takes to change your step types, then you must indicate another to contain this search string, IE a local / fileglobal / global station. Or store it in the memory of your labview. None of them are ideal, as it is best to keep the properties of the step in the step.

• How is it my local variable is not updated its value compared to what is happening in the while loop?

  Hello

  I am trying to extract data from a time that my statements updated in what concerns the number of loop iteration. I tried to use the two local variables and travel records, but without success.

  I also did the following example: http://www.ni.com/white-paper/7585/en and it works like a charm.

  I've attached the PNG file with declaration of the local variable circled in red. Join a VI in the next respnose.

  Thank you

  No, the two while loops are stacked and not parallel, which means the outer loop cannot go to the next iteration until all code in this document, including the inside so that the loop is finished.

• Change local variable boolian Programaticaly

  Hi all

  I came across something today, that I have ever dealt with in Labview...

  I downloaded a driver of instrument for a power supply, and got it working OK (using VISA on the USB communication).

  The example program pilot itself works very well and is a quasi State machine.  It it turns on and off and adjusts the voltage and current correctly, as it should.

  Then I need to edit the .VI to add a time on another timer .VI.  I wrote that the small simple VI and it works properly as it should.

  It's just a boolian power timer.  Lights at 08:00 daily, stops at noon every day.

  The problem I have is the boolian called variable "Output (T:Enable)" which is located in the .VI power supply example is a Panel button, but it is called several times as a local variable.

  (once again, I did not write this part and please no lectures on why you should never use a local variable...)

  When you change the State of the button "Output (T:Enable)" Panel, the power supply turns on and off as it should.

  The problem comes when I try to control this value boolian using my timer VI.  I've tried several things, and using debug, I can't 'Output (T:Enable)"to change state.

  The value will change ONLY if the button is pressed or not.

  ATTENTION: The illustrated local variable condition is also a security in case of short or overload, power off if the name cannot be changed.

  Is there a way I can trigger "Output (T:Enable)" using 'My exit timer' but always make sure that stop you it if there is a short circuit?

  This left me speechless... I tried several different things and just can not understand.  Any help would be appreciated.

  

  Thank you!

  The guy

  Hello guy!

  You are not sure, I understand the problem in its full extent, but I'm guessing that you want to trigger the event that controls the output (T: Enable)? If you want to programmatically, create a node of the control property and use the property "value (follow the signs). Writing of a local variable will not draw the event, although this will change the value of the façade.

• Direct local variable data VS

  Hey!

  I do LV Core 3 and hope someone enlighten me more... (Excersie 7-2 Solution more about 01:50 in the video to be more precise)

  According to this module, an indicator that is updated very frequently must be connected with direct data and not a local variable. Research assistance he said local variables to make copies of the data.

  It's a bit like this:

  1. I have an indicator that is 'coupled' to the X position of the memory.

  2. If I write a light directly he wrote directly to the X position of the memory.

  3. If I could write instead through a local variable... It would first create a copy of the data to write to the position indicator Y memory and then copy it to the X position of the memory?

  Thank you

  Peter

  Yes it's true.

  Now, imagine if you have a very large painting (and the elements of array must be States.map in memory).

  the first memory manager must find a place in memory where it can hold the table and you now have a memory more occupied by the local variable location.

• Initialization of a local Variable (variable uninitialized perhaps, but it is initialized?)

  I have behaviors very weird with my code. Some error messages complaining about reference uninitialized variables has led me to search around and found out that the shareware I use has very little initialization of local variables. CVI gives warning of the compiler on these variables, and I don't think he has caught even near each other. I went through the whole file and initialized everything myself.

  Even after that I booted my variables, however, the compiler always indicates they are unitialized, and my code still does not work. I've attached a screen of warnings from the compiler as well as one of the problem functions. Note that in the first warning (36, 9 WARNING: variable '(*tw1).i' maybe is not initialized when used here) there two notes under it, the one who told me where the variable is declared and who says "1, 1 Note: Add initialization to silence this warning. When I double-click on that note, he points to the top of the file, as if he says me to initialize the variable outside the function.

  I also found a very similar post about this but the user has said they were defining the structure twice.

  http://forums.NI.com/T5/LabWindows-CVI/local-array-initializations-not-recognized/m-p/2638119/highli...

  In addition, I understand that the screenshot I've not yet initialized the members of the struct, which I intend to do once that I get rid of these warnings.

  What should I do to remove this error? Any help is greatly appreciated, I've been messing around with this for too long. Thank you!

  emoser,

  I think that the strange warning is due to a bug in the analysis of the variables uninitialized in the compiler. The inaccurate diagnostic tests is issued at the line where you set a variable of local pointer to structure kiss_fft_cpx. It seems that the warning is caused during the pointer variable declaration is immediately followed by a local declaration of a structure of the same type:

  kiss_fft_cpx * tw1 = NULL;

  kiss_fft_cpx t;

  Basically, the incorrect diagnosis will happen:

  1. If a local pointer to a typedef struct variable is followed by a statement of the same variable type.
  2. If the second local variable declaration is not initialized.
  3. It doesn't matter if the pointer variable is initialized or not.

  The bug can come because the compiler can guess that the region of memory in the data segment continues from the pointer variable through the definition of the second variable, because they are of the same base type. A possible workaround in your case would be to go to the declaration of the variables of the same type (in your case, the declaration of the variable t) before the declaration of the pointer:

  kiss_fft_cpx t;

  kiss_fft_cpx * tw1 = NULL;

  Fortunately, this problem is fixed in the latest version of 2015 LabWindows/CVI.

  I hope this helps. I would like to know if the workaround works for you.

  Best regards!

• stage of statement do not write to the local variable

  I have a 2 local variables that are custom data, type, a container with 2 numbers u64, I am trying to assign numbers of these variables by using the stage of the statement, but variables do not change, here's my statement:

• LabVIEW: Concerns with local Variables and the readability of the program

  Hello everyone. I was hired for the summer to work at my University to a new laboratory. All right, but I have some problems with my main VI. I am a new user of labview coming from a C++ background. I went through several iterations of adding features, fixing bugs and doing my readable program. Before the last "cleaning" my program was so big that I couldn't see it all at once on my screen. My goal was to solve this problem. My solution contained three parts: use a state machine show parts of my code at the same time, to remove the son as much as possible, and use structures element to position my code manually.

  I met since problems write other programs that brought me here, and I saw a series of messages condemning the new programmers for their use of local variables instead of cables. I do not know my use of structures element as fancy boxes I can exclude the automatic cleaning is also a terrible practice.

  After doing some more reasearch on the subject I see local variables to add the duplicate in memory entries and their suppression can significantly speed up execution time. I have a delay programmed in a part of my code, but the rest can run as fast as he can as far as I'm concerned.

  I have attached my main program. Looking at it I think I did a good job to make it readable. But I'm not a user expert labVIEW.

  How to balance (do not use local variables, these structures element, etc.) efficiency and readability. Before you make these changes, there was so many things and so many threads all over the place that I couldn't even tell what was going on, and even less my teacher. I really wish I could see my entire program without scrolling on this computer of the laboratory (resolution 1280 x 1024).

  Advice on how I can achieve the efficiency, simplicity and common readability would be greatly appreciated. I feel I've done the latter while sacrificing the first two. Ultimately the three should probably be equally important.

  Thank you.

  As said altenbach, attach your event structures.  It should really be only need structure of an event, especially for a simple VI like that (I counted 3).  This is the second time I have recommended this today, but fetch JKI State Machine.  I use as the basis for most of my interfaces.

  Here's a way to manage the break with JKI.

  

  

  

• Initialize controls/indicators: invoke node-local variables Vales. Which is faster?

  Hi all

  I would like to get the opinion of the people. This thought just happened for me while I was reading some materials the other day.

  And I have not found any topic which talks specifically about speed after searching the forum.

  It is faster to initialize your controls/indicators using Invoke node OR write directly to the initial value of your local variables?

  From my experience (not large), I have always used the invoke node to initialize controls or indicators.

  But when I but this question, I did a simple reference point and it seems the local variable approach is faster, especially

  If you have the large number of orders/lights to initialize.

  Am I missing something here? The invoke node running something that writing a value of local variable would not do?

  I thought since you need to set the initial state by default for the node to invoke anyway, why not just write the desired initial value

  your local variables?

  I would appreciate if someone can express his own opinion based on their experience and knowledge.

  Thank you ~ ~

  I may need another Cup of coffee this morning, you are in fact callling the reset by default on each individual control.  My last despises, it is that you use the default method Vals.Reinitialize VI all failing.  It will probably be a bit faster than the method on individual controls.  Still not instant, if.

  Are a few msec is worth to you?  If so and you consider the local path, my advice is to group as many controls as possible into clusters for minimize you headaches.

• Why flatten data chain not getting past all about TestStand via a local variable of the string?

  I tried to go around a series of data in TestStand as a string using "flattened chain" of LabVIEW. When I create a local variable in TestStand of type 'string' and try to write the cluster flattened at this that he simply not transmitted. If I convert the string flat binary table and then pass it around, I can recover all the data very well.

  Is there something I'm missing here?

  I've attached an example Teststand sequence that illustrates this problem. If you run this sequence that the 1st test will fail, which is the attempt to simply pass the flattened string data structure and the 2nd test will pass as it is the binary table that I generated from the flattened string.

  Thank you

  Pete

  crossrulz is correct.  The Null character affects how TestStand handles the string.  You will need to specify the string to a binary string in the list of settings both the VI.  TestStand then encodes the stringso it can prevent the loss of data.

  If you need work on the binary string in TestStand, you will need to convert it to an array of raw data with PropertyObject.GetValBinary.

  

• How to find the steps associated with a local variable?

  In a sequence, we have to write or read from a local variable. Is it possible (for example right-click the variable) to find out related measures?

  Thank you!

  Are you talking about discover what steps use the local variable.  Because the measures are not really "related" variables.  Either they are or they aren't.

  You can use the search/replace tool.  Edit > find/replace

  In the look for:, enter inhabitants.

  You can check her search for: box, and then select the order in which you want to search.  This should show you a list of all instances of the local variable.

  Hope this helps,
