• Code to skip the steps: initialization of local variables failed

  Hi all

  I'm upgrading some software LabVIEW RT I inherited LabVIEW 2011 to 2015 LabVIEW (32-bit) on a host Windows 7 Professional PC. The target is an SMU-8135. The software ran well when it is compiled under LabVIEW 2011.

  I modified the code to enable the monitoring of what is happening by looking at screen on the target outputs. The initial error that brought me here is that a local cluster variable initialized in the first window of the flat sequence described below have been appearing as the in windows later.

  The code begins with the initialization of local variables in the first window of a flat sequence and provides a quick line of text output to the display of the target (call this text #1) (using RT Debug String.vi) I send two lines of text so that a new row is created and later text does not replace it. . It then writes to the next window in the sequence flat screen two groups of text output to the target. Second text in the window 2 (#3 text) output is equipped with a wire entry from the error from the first text output in the second window (text #2). That is the second exit must wait for the first exit to complete before being sent to the screen.

  I see now some weird symptoms:

  1. when I connect to the target under a remote debugging session I see expected display outputs. Not remotely connected, text #2 is displayed. The code passes to the third window in the flat sequence, so everything in the two window should have executed.

  2. the text #1 appears on the target screen * before * I get the message "Welcome to LabVIEW Real-time 15.0." Is this normal? Whence this message? I searched my screws and subvis to this text and it is not there then it mucst come LabVIEW screws somehow.

  This all started with local variables no initialization in the first window, so apparently, I have a problem of data flow. Given that the problem disappears under the remote debugging, I'm a bit of a loss.

  Thanks in advance for any help,

  Your "text 2" seems to be powered by a collection of nodes comments to "initialize on compile or load.  This will return once the empty string the first and therefore should not be display nothing until the code I run a second time.  That is the crux of feedback for?

• Block initialization parameter default value of the session variable used in default prompt as "(toutes les valeurs de colonne)" "

  Hello

  I have a business requirement for a dashboard that we built location to get the users that belong to a certain geographic location to the default view of the dashboard with guests together in their geographic area.  He is just giving them a default view to enhance their experience when they connect each day.   Because of the way that we put the default value for the period of time they watch, with the HELP of SAUVÉ the CUSTOMIZATIONS IS NOT AN OPTION.

  I created the default values for the prompt called "area" in a block of initialization. This variable is called V_USER.

  My problem is that only about 80% of users have a value of 'Area' in the hierarchy of our employees.   I would like to someone else by default "(toutes les valeurs de colonne)". "  I was unable to understand how and where do.

  Some of the things I've tried:

  (1)	Setting the default value in the initialization of an empty space block ("in SQL)
  (2)	Setting the default value in the initialization "(toutes les valeurs de colonne) block '"
  (3)	Setting the default value in the initialization block 'null '.

  None of them have worked and the result is that the user who does not have an area ends with a load of zombie dashboard, and while the guest gave rise to fashion "- select value -", the user must press "Apply" again to get the dashboard to display the data.

  The text which lies behind the encircled area in green below correctly becomes the value of the variable to V_USER (it is empty as default and I don't have a box).

  For @{biServer.variables ['NQ_SESSION.]} {[USERS ']} the default zone must be @{biServer.variables ['NQ_SESSION.]} {[V_USER']} {}

  In the red circles below you can see that the guest actually becomes a value: *) nqgtu(* )

  
  

  The illustration below indicates the default value for a user without a box. the second quick block is not updated until you press on apply again...

  

  Thanks for your comments.  I was not able to make this work for my needs.  I have however to solve the problem by changing using a 'SQL result' for my default selection.  Then I created a query that returns rows NULL unless there is a correct answer:

  SELECT 'Service Delivery MOS '. "' Organizational hierarchy. "" Area ".

  "MOS DELIVERY."

  WHERE ("organisational hierarchy". ("" Area number "> 0) AND ("Service Delivery MOS". "Organizational hierarchy" "." " Zone' = ' @{biServer.variables ['NQ_SESSION.]} {[V_USER']} {} ")"

  The "returns no line' I mentioned above resulted in all values being selected.

• store internal variables in the nodes mathscript/scilab

  Is it possible to store the values of local variables in mathscript node? Maybe have an initialization section where variables are implemented and then later updated. And then something to reset the closure of the vi? Im guessing not, im guessing that we must do the same as labview, pass new releases at the entrances, but it is much more natural in a text based language to do it this way (for me anyway).

  Gordal salvation,

  You can use the backup and loading of orders to store variables for your scripts in a file.  Note that these commands will a warning glyph occur which reduces performance, so what I propose is the following:

  

• Repository initialization Blocks (OBIEE) variable

  Hello

  I've created a repository variable and the type of variable is dynamic, the variable called "Read_Data" and I initialized the block with this query "select FirstName from employees where idEmp =: val.

  My problem is in obiee when I call the variable I need to initialize the value of idEmp

  How can I do this?

  I have another on the initialization blocks why when I use this query 'select FirstName from employees' and I get only the first data, even though my table contains 100 data?

  Thanks for help

  In addition to this Gabin says (initialization) to your first question, I assume that you have some idea of 'dynamic variable repository' a little bit.

  A dynamic variable repository is not as dynamic as you imagine. The main feature compared to a static is that the value of the variable comes from a SQL instead of being entered manually in the administration tool.

  SQL is a type of static query and not refresh when you call the variable and want to use it, but it is filled only once or maximum according to the calendar. For example, you use this query to store values as the period under review (and you have a query that retrieves the period max responsible for your data once per hour or something like that).

  Even a session variable will not really what you expect or at least not exactly how you think that it: initialize the variable when you call it works only once if you check the box "performance" you just to delay the execution of the query until you access it for the first time , but at this point, it is defined and it will not refresh until you do not close the session to begin a new.

  So for what you are trying to do, I suggest you find another way because it really does work.

• How to create a group/list of the variables in the box for display in the text field, in the format in annex

  I need to identify a series of variables single-response checkbox and display links selected (as a group) in a text field in an annex (comma, space) format. Last week, you provided a small script for a similar requirement by using the list box (multiple response) variables. This time, I need to know how to identify the variables of the box officially and, presumably, use a similar script to display the results in a comma, space format.

  You've been a great help.

  Thank you

  Here's the script for this situation. It assumes there are ten boxes named cb1, cb1, cb2,... cb10.

  // Custom Calculate script for text field
  (function () {
  
      // Initialize the string
      var v, s = "";
  
      // Loop through the check boxes to build up a string
      for (var i = 1; i < 11; i++) {
  
          // Get the value of the current check box
          v = getField("cb" + i).value;
  
          if (v !== "Off") {
              if (s) s += ", ";  // Add a comma and a space if needed
              s += v;  // Add the selected value
          }
      }
  
      // Set this field value to the string
      event.value = s;
  
  })();
  

  You will have to change the name of the field and start/end numbers to match your form.

• How to share a variable between the Mathscript Windows and a Mathscript node

  Hello

  I'm trying to share (just) a variable between the Mathscript Windows and a Mathscript node. I don't know why, but the use of the "global" Matlab function makes the mathscript node output formats change.

  I'm looking for a "Mathscript RT V9.0.1 module" as it may seem, there is. French technical support have some difficulty to find...

  Hi patrick33,.

  The code that you have attached should not report an error, so it seems that something has gone wrong with your installation of MathScript. My best guess is that it is the problem that is described in this knowledge base article. Your signature says that you use f3 patch, which is a good start. But the KB lists some other steps to take when you see errors about MathScript, impossible to compile. Can you try the procedure described in the article and let us know if that fixes the problem?

  Thank you

• Using a Global Variable for the input recorder DisplayRange

  I'm assuming; Since I can't do it; that you cannot change the display range of a graphic recorder by using a variable.  If there is a way I'd love to know how.

  Thank you!

  Determine if you can use a global variable is to click right in the parameter field. If the global variable is available in the context menu, then you can use a variable y.

  You can use a variable of the y-axis from the settings.

  You cannot use a variable for the display range of the x-axis parameter. This is because DASYLab needs to know the amount of memory to be allocated at the beginning of the measure.

• Programmatically create an appointment: missing variable in the container of result

  Hello world

  For my purpose of tests, I need to programmatically create a sequence. In this sequence, I need to insert steps from Rendezvous.

  Everything works very well when they are created, but when I run the sequence / stages created this error always appear for the appointment stage:

  • Unknown variable 'TimeoutOccured '; Error in the item "Result.TimeoutOccured".

  According to using TS, this variable must be created when I set up stage of the operation to date. Drag and drop step of inserting TS palette works very well, and the variable is created when you select the operation "appointment". But when you do the same thing through programming, the variable is not created.

  Here are the steps performed to create the Appointment stage:

  1. I have create a new step by using the Engine.NewStep method
  
  
  2. I put the name of the step using Step.Name
  
  
  3. I put the properties of an appointment using a statement (Parameters.BranchesRendezVous.RDVStep is the variable holding the reference of step):
  
  
  • Parameters.BranchesRendezVous.RDVStep.AsStep.Operation = 1, //A value that specifies the operation of the step to perform. Valid values are 0 = crΘer, 1 = Rendezvous and 2 = Get Status
  
  
  • Parameters.BranchesRendezVous.RDVStep.AsStep.NameOrRefExpr = Parameters.BranchesRendezVous.RefName, //Contains the expression name Rendezvous for operation of creation and expression name Rendezvous or reference for all Rendezvous operations
  
  
  • Parameters.BranchesRendezVous.RDVStep.AsStep.TimeoutEnabled = False, //The Timeout allowed for the operation of Rendezvous
  
  
  • Parameters.BranchesRendezVous.RDVStep.AsStep.ErrorOnTimeout = True, //The Timeout causes Run-Time Error for the Rendezvous operation
  
  
  • Parameters.BranchesRendezVous.RDVStep.AsStep.RendezvousCountExpr = Parameters.NbBranches, //The expression number of Threads by appointment for the create operation
  
  
  • Parameters.BranchesRendezVous.RDVStep.AsStep.Lifetime = 3, //A value that specifies the lifetime setting to use for the create operation. Valid values are 0 = same as sequence, 1 = even as a thread, 2 = use reference object, and 3 = same as execution
  1. 4. then I insert the step in my current sequence by using the Sequence.InsertStep method

  Everything works fine, the appointment stage is perfectly created and all the properties are set finely. However, the TimeouOccured variable is missing in the container Step.Result (help says TS that this furniture exists when the step is configured as a date (see operation = 1)).

  I'm doing something wrong somewhere? Why did this variable missing?

  You probably need to create the property programmatically using NewSubProperty().

• How to make appear a message that can enter some settings such as a variable for the next step?

  Hi all

  How to the dialog box or window pop up a message that can input some parameters as a variable for the next step?

  My sense is if Teststand stage can do that, not using Labview or other language.

  Thank you

  Take a look at the Options of a stage of pop-up Message tab. The response is returned in Step.Result.Response.

• Update of the variables of the container

  Hello

  in 4.1.0 TestStand I noticed that, when I change a container type by adding new elements that the variables of this type automatically receive new items, but without their default values (I use it as a replacement for constant values that TestStand does not). Instead, the new elements are set to 0 (they are all numbers).

  Following questions:

  • Are variables inside the sequence of files automatically updated when loading the sequence file? or only the sequence currently in memory files when the type is changed?
  • Is that the behavior of use 0 as a default value instead of the default value in the definition of type of design or a bug?

  and a request: I think it would be good to have constants to TestStand, that is, definitions of the same type in a TypePalette-INI-file, which can be used without an instance of a variable.

• Support of the shared Variables in the third part XP embedded based of PTC?

  I sent a request in an embedded XP touch function (third party). The application works very well, but hosted on a RT (sbRIO Board) shared variables are not getting updated in the app on PTC

  1. the PTC is part of the project as a Windows XP Embedded Touch Panel

  2 NI TPC Service has been installed on the PTC and the application can be deployed remotely from the PC development via ethernet. (Where network connections and communications are OK)

  3. using distributed in the development computer systems manager, I can see that the shared variables are getting updates on the network

  I think that the problem can be solved if the following programs are installed on the TPC

  A. Support for variables that are shared for XPembedded

  B. shared Variable engine

  I tried to install the support of variables shared Program Files > National Instruments > Labview 8.6 > PDA > utilities > Variables > x 86 - but I get an installation error "cannot find the application for the Pocket PC applications Manager.

  Shared variable engine was installed from the ve220 folder. The program is installing. But the engine Variable is not start Control Panel > administrative tools > Services, Xpe, the service is stopped and cannot be started. When I try to start the service, I get the following error on PTC

  "Cannot start Service engine of National Instruments Variable on the local computer."

  Error 1053. Service has failed to demand launch or timely control.

  Please suggest solutions to the addresses above or another of the following:

  1. support of variables shared for XP built-in PTC

  2 Installer engine Variable shared.

  Thank you

  Krish

  Problem solved!

  Update for interested people working on XP Embedded PTC

  Just to ensure that shared Variables were indeed accessible to the TPC, I wanted to install Distributed Systems Manager 8.6 on the TPC. However given that the TPC was only 1 GB of DOM (disk on memory) and with all the software that I had tried, there remained only a few megabytes on the system. I had to add an another DOM of 2 GB.

  All products in the Installation went well, with the exception of the Logos NOR (Version 5.0). Logos OR installation has failed repeatedly.  I tried to install NI Logos separately, with the same results. Then I had this intuition that NI Logos had anything to do with the question.

  Then, I downloaded the new version of NI DSM 2009 SP1. Even if it were to settle on any fresh system without Labview, the installation would not proceed beyond the stage of configuration. I tried to install NI Logos of the folder on the download of new products separately and it worked magically!

  Once the new Logos (Ver 5.5) installed, the Shared Variable engine starts automatically and the shared Variables are finally unleashed - free stand up and shine! I thank Almighty God!

  On the lighter side, come to think of it - to run an application about 400 KB, we need NEITHER of Run Time, XP embedded, DSM, Logos...  (around 900 MB). Can make us everything simpler?  Invite your comments...

  Thank you
