• Cannot create global variables in calc Manager in 11.1.2.1

  I am trying to create execution variables to use in calc Manager rules at the application level. But when I select the name of the Application and click Create new variable, that it gives me the dimensions used in my App list rather it gives some names of General dimension. I can create variables at the level of the plan type, but I'll try to avoid it.
  
  How can I create performance variables in Calc Manager rule to the application level?
  
  Thank you

  This is how the product works when it comes to global variables:

  -During the creation of the global variables so only common dimensions are selectable (period, currency, entity, year, period, etc.) makes generic sense or defined by the user dimensions are the specific database because applications can have several common dimensions and other databases.

  -At the database level dimensionality, you select the database of planning when creating variables that use the user defined dimensions and overall at a higher level when creating variables that uses common dimensions.

• How to create Global Variables in Essbase

  Hi gurus,
  
  In essbase automation, I saw generally the statement below.
  
  Connection $1 identified by $2 $ 3;
  
  and of course many other statements also.
  
  1. now, my question is where and how can we create the variables ($1, $2 and $3).
  2. they are Substitutinal Variables or Environment Variables.
  
  Pls let me know in detail how to create and define the variables above.
  
  
  I tried to create them as variables indirect in environmental assessments, but when you run the maxl order Login $1 $ 2 $3 its saying this $1.. variable cannot find etc.

  They are variable positional parameter and are passed in a maxl script, you can read all about it at:-http://download.oracle.com/docs/cd/E12825_01/epm.111/esb_techref/maxl_syntax_vars.htm#syntax_techref_proj_maxl_ddl_utils_shell_d0e227

• global variables shared between several targets of RT

  Hello

  I'm looking for some information about variables shared between RT communication network.

  Scenario: a PXI 'master' and several 'slave' PXIs running that screw RT. data is available in the form of a cluster of definied type on each slave PXIs (inside a non deterministic while loop). I guess I create global variables of network shared for each PXI slaves. A variable for each slave. I only write data in these variables in one place (above mentioned, while loops), on the PXIs slave. I need to read that data in a way with loss (I just need that value the most recent, as tags) from the master PXI.

  Question: can I simply use "network shared variable" settings by default? I mean, I do not enable the option RT FIFO (single element), because I think that for a cluster that is a no go in the case of RT (variable length)?

  What do you think? Or would you have better idea how to share data between slaves and masters RT targets (I do not have deterministic/losless transmissions, only these last values)?

  I think that the way to proceed is to use the shared Variable Aliasing/binding - they allow you to 'link' shared variables in any of the multiple targets. https://forums.ni.com/t5/LabVIEW/Bind-Alias-shared-variable-to-scan-engine-variable/td-p/3290043.

  You can also use shared variables of programming access to access running on another target: http://zone.ni.com/reference/en-XX/help/371361G-01/lvconcepts/usingdynvarapi/

  With regard to the other methods - you could always disseminate data via UDP multicast (or with a TCP/IP connection manager).

• How to create a Global Variable through the Project Explorer

  Hello world!

  I know how to create a global variable (in a vi through the range of functions...).

  but I'm missing a way to create one via the Project Explorer.

  It's a missing feature or just this documentation (and the intuition of myself) are missing?

  It would be very convenient.

  THX for your time and hope that answers.

  jwscs

  Right click on my computer > new > new... > select Global Variable.

  EDIT: although I agree with Gerd (he probably wondering why you need so we can recommend a better way ), I rarely use them in easy to write once - read many applications such as security levels overall program at initialization (VER) to read later, but NOT modified.  I know it would be better to make a good class, functional Global Variable (FGV) or a motor Action (AE) but globals ARE practical and safe IF used wisely.

• How to create a global variable?

• Create the global variable

  I am new to animate. Please can you tell me how I can declare a global variable?

  I try to have a single button that plays the next 10 frames, another button that plays the next 20 images. I put the event listeners for the buttons on the first image. I'm putting the code on the timeline each 10 images that works if the game has to stop. I would like to connect with some global Boolean values. The project is the html canvas.

  It must be simple. Can you help me?

  Scope of variables in canvas mode:

  myVar = 1; variable is accessible everywhere in the current page

  this.myVar = 1; variable is accessible in all the images of the current clip

  var myVar = 1; variable is accessible in the current context only

  So yes, the creation of a global variable is simple the most.

• Create a global variable, get/set of action of the div nested

  I read a lot of posts on this subject that offer slightly different solutions, but I can't seem to get one of these solutions to work in my context.

  Perhaps my difficulty comes from the fact that this div is nested in a symbol and 2 groups of div. I try to access within a click action.

  So it goes: Stadium > Parent symbol > Group div > div group > Group div with the click action.

  I create the variable in a compositionReady on the stage action. I tried the following statements:

  • sym.myVar = 'myVal ';
  • sym.setVariable ('MyVar', 'myVal');
  • setVariable ('MyVar', 'myVal');
    
  • var myVar = "myVal";

  And the Committee of action of the div group, I tried the following syntaxes:

  • Alert (sym. MyVar);
  • Alert (sym.getVariable ('myVar');
  • Alert (getVariable ('myVar');
    
  • Alert (sym.$('myVar'));

  And I tried all reasonable combinations of elements on these two lists.

  Anyone know what I'm missing? All documentation to help me get my head around the principles at work here would be appreciated!

• DLL and global variables

  OK, here's a strange problem.  I am very new to create the dll, so I don't know that I have just an installation problem.

  But I'm trying to pass a global variable of a host program to its attached DLL.  I got this job when I was the CVI 2014. I recently upgraded to 2015 and then started getting "undefined symbols" errors.  With some struggle I managed to compile again, but broke the variable connection in the process.

  I have compiled my DLL in debug mode so that I walk in from the test project.  Right now, my global variable exists in the test project, as well as in the DLL.

  Can I export the variable and the use of DLLIMPORT/DLLEXPORT?  Confused and curiously not to find anyone quite like this on the forums.

  EDIT: this post stack overflow described pretty well from my experience.  I am linking statically.

  Well, what do you know?  I found my problem.  This draft article and example WERE vital to the solution.  This article called, "using the Export method qualifier"was also useful.  I'll cut to the Chase...

  If you use a qualifier of export on the definition and the import on the declaration, LabWindows/CVI identifier export symbol.

  This is the right key.

  So in my example, it should look like this:

  DLL fichier.c

  int DLLEXPORT varName = 0;

  Header.h DLL

  int DLLIMPORT varName;

  Project that uses DLL.c

  #include "header.h DLL.
  
  varName! = 1 ;  a method to change this variable for local use

  Pretty easy, huh?  But wow, it took some time to find.

• Functional global variables with polymorphic VI

  Hello

  I am keen to build a functional global variable in a polymorphic VI. So, for example in a functional global variable, we have case structure. I want to build separate VI for the structure of the case and make a polymorphic VI.

  Is it possible that I could use a polymorphic VI rather than business structures?

  Thank you!

  You could create a polymorphic VI that serves as a wrapper for the FGV.  The idea is that each instance of the polymorphic VI called FGV with selected appropriate case-sensitive.  Then your API is the polymorphic VI instead of FGV.

• global variable functional to read and write data from and to the parallel loops

  Hello!

  Here is the following situation: I have 3 parallel while loops. I have the fire at the same time. The first loop reads the data from GPIB instruments. Second readers PID powered analog output card (software waveform static timed, cc. Update 3 seconds interval) with DAQmx features. The third argument stores the data in the case of certain conditions to the PDM file.

  I create a functional global variable (FGV) with write and read options containing the measured data (30 double CC in cluster). So when I get a new reading of the GPIB loop, I put the new values in the FGV.

  In parallel loops, I read the FGV when necessary. I know that, I just create a race condition, because when one of the loops reads or writes data in the FGV, no other loops can access, while they hold their race until the loop of winner completed his reading or writing on it.

  In my case, it is not a problem of losing data measured, and also a few short drapes in some loops are okey. (data measured, including the temperature values, used in the loop of PID and the loop to save file, the system also has constants for a significant period, is not a problem if the PID loop reads sometimes on values previous to the FGV in case if he won the race)

  What is a "barbarian way" to make such a code? (later, I want to give a good GUI to my code, so probably I would have to use some sort of event management,...)

  If you recommend something more elegant, please give me some links where I can learn more.

  I started to read and learn to try to expand my little knowledge in LabView, but to me, it seems I can find examples really pro and documents (http://expressionflow.com/2007/10/01/labview-queued-state-machine-architecture/ , http://forums.ni.com/t5/LabVIEW/Community-Nugget-2009-03-13-An-Event-based-messageing-framework/m-p/... ) and really simple, but not in the "middle range". This forum and other sources of NEITHER are really good, but I want to swim in a huge "info-ocean", without guidance...

  I'm after course 1 Core and Core 2, do you know that some free educational material that is based on these? (to say something 'intermediary'...)

  Thank you very much!

  I would use queues instead of a FGV in this particular case.

  A driving force that would provide a signal saying that the data is ready, you can change your FGV readme...  And maybe have an array of clusters to hold values more waiting to be read, etc...  Things get complicated...

  A queue however will do nicely.  You may have an understanding of producer/consumer.  You will need to do maybe not this 3rd loop.  If install you a state machine, which has (among other States): wait for the data (that is where the queue is read), writing to a file, disk PID.

  Your state of inactivity would be the "waiting for data".

  The PID is dependent on the data?  Otherwise it must operate its own, and Yes, you may have a loop for it.  Should run at a different rate from the loop reading data, you may have a different queue or other means for transmitting data to this loop.

  Another tip would be to define the State of PID as the default state and check for new data at regular intervals, thus reducing to 2 loops (producer / consumer).  The new data would be shared on the wires using a shift register.

  There are many tricks.  However, I would not recommend using a basic FGV as your solution.  An Action Engine, would be okay if it includes a mechanism to flag what data has been read (ie index, etc) or once the data has been read, it is deleted from the AE. 
  
  
  There are many ways to implement a solution, you just have to pick the right one that will avoid loosing data.
  

• Global variable control and simulation

  Hello!

  I have a probem with the export data of the Simulation loop in the graphic form.

  I have created a global variable, but in the façade is not updated or exported the data necessary, but in the file as a global variable do?

  I would like to gather (gathering) all the data after the simulation data file as Excel (trace the export data to Excel or save the spreadsheet file) as well as the image of terminal.

  Please find attached my files - someone has an idea or a solution?

  There must be some easy trick

  Thank you!

  (1) why are you doing this problem much more complex it must be using a global variable and another loop like that?

  (2) why you son of path of the VI in the picture? You try to crush the VI on disc with the image?

  (3) be careful not to ignore the output error.

  The code shown in the attached screenshot works very well. I'll take Bravo if it helped you.

  

• Functional Global Variable reference

  Hi all

  I want to update the value of the indicator element in primary VI, I don't want to use the global variable, due to the problem of race condition. So I create a functional global variable to control reference. It is reliable and can avoid the race condition critical?

  I have attached two Test VI.

  Thanks for your advice.

  Personally, I use user events to send data to the main VI and then he can update the indicator.  This generally works very well since most GUI screws using a Structure of the event anyway.

• How to make a USB-TC01 temperature data a global variable?

  Hi all!  I have a simple question (probably).  I bought the box USB-TC01 and with the software came a VI called LabVIEWTempLogger.  This VI reads a thermocouple voltage and internal conversions using DAQmx and a CYC edge to give a reading of simple temperature.  My problem is that I want to use this temperature in an another VI, then I want to make a global variable of temperature of LabVIEWTempLogger.  How to set a global variable such as temperature of LabVIEWTempLogger?  Thank you!

  You must get out of the recorder temperature VI the DAQ Assistant. Put it in a Subvi if you wish.

  Your main VI has some problems. The first fact a comparison is equal to the current temperature. Never make an equal comparison on a floating point number. Use in the range and force.

  The local 'Set Temp deg C' should be replaced by a wire from the Terminal. All local variables should be replaced by a wire. You can easily have the cable terminals from outside the main loop.

  Can't the difference in code in the States True and False when you read voltage.

  Don't use VISA bytes to the Serial Port. It's just bad style. You programmed it for a terminal character LF to get rid of fixed forward and set the number of bytes to read at a high number. Playback will wait until the stop character is detected and then automatically end.

  Finally, you have already created a world so I do not understand your questions about it.

• Table as a global variable

  It left me speechless.

  I have looked through examples and the forum, but could not find a solution to my problem.

  I am writing a program that has a table of values on the screen before and various under vi that update the values in the table.  I have to be able to read the values of the cells in the table, but I understand that this cannot be done.  So I try to use tables to keep the values that I want to read and just write to the table when I have to.

  In any case, I need to create a table that can be accessed by all the sie.  I added a table to the gobal.vi control but when I select a sub vi I get a node of Blackboard, and if I have anything wiring him get a cut wire.

  I have attached the screws overall and initializatio

  You have added an empty array to the Global Variable. Just add a numeric control to the table in the GV, and you will get a table of numerical values, which you will be able to use.

  Thank you
