• tasks timed inside the loop

  I have a program that has multiple tasks, and I want to work at different frequencies inside the loop.  I wonder what is the most effective way to do this?

  I read on several tasks running button push-based or events, but have not found much of the timed tasks.

  Is the loop timed the best way to go with this?  Have a loop timed for each required task?

  I have attached a vi corrupt that shows what I'm trying to do.

  I'm sure there is an easy solution, but want to find more effective this way.

  Thank you

  For a simple task like this, just turn the loop at the faster pace, you need and perform other tasks to integer multiple of it.

  Here's a simple project (LV 8.6)

  (Of course you have serious problems with stolen memory, as you grow berries of infinite sizes in the uninitialized shift registers. Which must be fixed too).

• conditional of the loop will not control read in a business event

  I made a simple conditional to the loop, with a timer and a generator of random numbers in the loop as a stop button attached to the conditional stop Terminal.  Everything works well and stop the loop when I click on the stop button. But I then wrap the conditional for the loop with a structure event and create an event to run the conditional for the loop.

  To my surprise, when I run this updated VI I can never get the loop to stop via the wired button until the conditional terminal stop.  How is what happens? And how to do this?

• Is it possible to put the property inside the loop node?

  I created three nodes of separation of property (color graphics) for my 3 XY graphs.

  Is it possible to have a property node, put this tag inside the loop where I ranges from 1 to N, and say plot_color_i

  where plot_color_1 would update 1 XY graph, plot_color_2 update XY Graph 2, etc. ?

  See the attached VI.

  Yes.  Create an array of references to the XY graphs and have this auto-index in the property node in the loop For

• Change the width of digital pulse inside the loop

  Hello

  I am looking for a solution that allow you to change the width of digital pulse inside while loop.

  Thanks in advance

  

  Check the operation of dataflow and single pulse meter output

  First counter generates little time, then big time.

  Your AO task then is to adjust tension on IT after Dig pulse. After the AO pulse width, he needs to put down

  If the Trac software is small enough for you, you might have used USB-6008 ($250), not Xseries $ 1600 - apparently of an overdose. X series can do this work with a void microsecond resolution.

  

• Graph XY plotting the question with the data of repeting inside the loop

  Hello

  I have this problem I'm having with my plots. Maybe there is a better way to do it.

  I have a set of data that I use inside a loop. I want the loop to keep reusing the same data. The reason I do that is because I want to continuously stream that loop exactly like that of my data file and plot it and do something different with it. My problem is that the XY graph does not draw correctly. I wonder if someone can help me to get field work and alo get data through the graph XY waveform.

  The files are attached. Test.VI is the main vi

• The sum of several waveforms, created inside the loop for

  Hello

  I am currently viewing the Gibbs phenomenon by adding several sine waves. The issue I'm having is that I can't understand how to add sine waves created in the loop. I have attached a picture of the basic structure for my project below. I tried to use simply "add" with a feedback loop, but it seems that my programming skills apply here. Any suggestion is appreciated. Thank you!

  Something like that?

  1. make sure that you "reset" the generation of signals with each iteration

  2. with the waveforms, please make sure that the sample rate is the same.  This may be a problem with the first iteration.  Then add in a check to use only the first waveform on the first iteration.

  

• Node inside the loop - out of memory

  Hello world

  I have a Mathscript node inside a Subvi is called inside a loop for. After a few iterations of the loop, I run out of memory. That's why I added another node in Mathcript with the function 'clear' outside the Subvi, hoping that after I get the variables from the node I could erase the memory of the Mathscript, but this does not work, it is always short of memory.  Is anyone know how can you delete variable memory Mathscript node, once they were saved in the variables in Labview? Thanks in advance.

  

  You don't even really any useful information to solve the problem. As I exaplained, constantly deleting data sets just to reassign them to the next iteration is generally ill advised, because it causes just more performance and same memory fragmentation issues. It is best to operate locally as much as possible.

  Who wrote the code matlab? Maybe it's very inefficient? What is doing? Perhaps rewrite in LabVIEW you gain significant performance.

• indicators inside the loop does not display a value in hand VI

  I have little indicators one table and another is the display image to the inside OF the loop in the sub vi (see attachment of files). If I'm running under vi individually, it works fine, but when I call these indicators in my main vi It shows something, and these indicators appear to be empty or blank, although at the same time the sub vi indicates the values of these indicators perfectly.

  Can any body guide me why I can't see these indicators correctly in vi main even if I can see them in the sub vi correctly.

  Control references that you want to pass to your VI are the images and output array references If you want to update.

  Then, in your Subvi, write in the nodes property of these references If you want to see the updates on your hand VI.

  EDIT: Although this method can you work around your immediate problem, I don't think it's something you really want to do often. There is probably a better way of this option to get the results desired real architect.

• Cannot use Select inside the loop For inside the SCTL (FPGA) - Bug? An alternative?

  When I put a Select statement inside a loop in a loop of Timed Cycle in LabVIEW FPGA, I get the following error when I try to compile:

  "An internal software error occurred. Please contact National Instruments technical support on ni.com/support with the following information:

  Error-61003 occurred at

  Possible reasons:

  LabVIEW FPGA: you cannot include this function in a loop For when the loop is within a single cycle timed loop. »

  I didn't know that whatever it is documented that says that this is not allowed; is this a bug or am I missing some documents?

  The code that causes this error looks like this, inside a SCTL (ignore Boolean wire wandering behind the loop for)

  

  I came up with the code below instead, which compiles into one Cycle timed loop, but it is a bit ugly. Does anyone have a better suggestion?

  

  This issue is currently followed under the CAR # 592391. Please keep an eye on our patches and new versions as usual!

• Move data directly from inside the loop

  Is it possible to move data directly from inside a loop outside the structure of matter in real time? I would like a chart of the data in a structure of matter in real time outside the structure of the case. Ideally, it would include information of the real deal and then the waiting period as a '0' for false case. Attached is a version simplified VI I'm working. I tried the local variables, but they only read the first item for loop puts each cycle T/F. One idea is welcome including a complete change in the structure of the VI.

  Thank you!

  
  

• Event inside the loop 'for' confusion

  Hi all

  I have an event inside a N = 2 for the loop, which generates an array of 2 elements (auto-index mode). The first value is a first event, the second of the second round. The events are the mouse clicks on a front panel with many buttons control.

  Am I able to access the i counter inside the front loop of 2 elements output table? He does not appear.

  Maybe I want just 2 events in the order I should put two copies of this event in a sequence of 2 image... but it creates the need to set up the event twice... a concern, because it contains many possible sources.

  Ive tried everything in loops, by the way I like a local variable, tunnels, shift... registers but I don't seem to be able to access I have during the loop.

  Can anyone suggest a method or a better structure/approach for this issue.

  In any case, it seems that the program is blocked waiting for the second round, so I can't do anything with the value anyway?

  I want to take action after the first test and before that I'm waiting for the second event.

  Thank you

  OK, you're much too complicated things dong.

  • Use a unique event for all low Boolean mice, then use the ctrlref of output event to detect only one. For Boolean values, you can use an array of Boolean instead of all these individual buttons.
  • Don't do the "table of cluster... unbundle" songs and dances. It's just ridiculous! 'array Index' is sufficient.
  • You need an event for the stop button.
  • The structure of your outdoor sequence has no purpose.
  • The coloring is registered with VI, no need to recolor with each race.
  • Do not reproduce any of this code. Your internal matter differs only in a constant of the diagram, it's everything that belongs inside the case. The "subset of table to replace" belongs to the outside.
  • Now, simply do the processing in a new event and ignore if the State isn't fair. Modify if needed.

• How to show under condition inside the table

  Hi Experts,

  JDev version 11.1.1.4.0.

  I have a table inside the table, I have 2 Date.MinValue i.e startdate and enddate. The necessary should be fired in the click of a button, apart from the table record.

  For each line, there is a date of start and enddate.

  Scenario1:

  StartDate = null. end date = null. When the click on save the date must be recorded and no message validation should be triggered when the click on the button Save. (It works fine).

  Scenario2:

  startDate = date and end date = null. When the click on save the date must be recorded and no message validation should be triggered when the click on the button Save. (It works fine).

  Scenario3:

  startDate = null and endDate = someDate. When the click on save the date must be registered and validation should be triggered only when the click on the button Save. (It works fine)

  Scenario 4: When I go start date and end date and remove the start date and pulls on the validation tab manually. But I want to be pulled on save button that is outside the table.

  Thank you

  Roy

  Try playing with the immediate property for af:table and autosubmit to date component. MinValue (must be false)

• If doesn't work is not inside the loop for the registration of the declaration file?

  Hello!

  I have the following documents open in Photoshop:

  123456_mrp_ou. TIF

  869548_mrp_ou. TIF

  896589_mrp_in. TIF

  896589_mrp_ou. TIF

  .. and I have this if statement in a loop for to search for files with a specific 'pid' number and save them in the folder My Documents:

  var originalPid = 896589
  for(i = 0; i < app.documents.length ; i ++) {
        activeDocument = app.documents[i]
          if(activeDocument.name.substring(0,6) === originalPid) {
                  var standardSave = new File('/Users/constantincerdan/Documents/' + activeDocument.name)
                  activeDocument.saveAs(standardSave, TiffSaveOptions, false, Extension.LOWERCASE)
  }
  }
  
  
  

  It did not find the two files and save them when I run. However, the loop without if statement runs very well and saves all the documents in the Documents folder:

  var originalPid = 896589
  for(i = 0; i < app.documents.length ; i ++) {
        activeDocument = app.documents[i]
                  var standardSave = new File('/Users/constantincerdan/Documents/' + activeDocument.name)
                  activeDocument.saveAs(standardSave, TiffSaveOptions, false, Extension.LOWERCASE)
  }
  
  
  

  How it works with an if statement so that it saves only the two?

  Any help is very appreciated!

  You are comparing apples to oranges, you need to compare strings.

  originalPid = 896589;

  alert (typeof originalPid);
