• How to read the data processed on frm loop on each iteration of the loop?

  Hello...

  I need to display numbers as 1, 2, 3... constantly using the loop on each iteration (IE out of the loop using threads). I generated the numbers 1 2 3... using the back power node... I can read the final value after the last iteration of the loop for.

  I connected an indicator of the loop for. This indicator displays the value as a 4 If the number of loops that 4. I couldn't view 1 2 3 4 an indicator of items at each iteration.

  I'm in a position to read the value of the variable on each iteration of the loop. Please help me fromthis regard...

  Thanks in advance...

  In fact, I'm programming for multiplication of two table 2D.

  I need to select the particular code to perform this action using the structure of the case. who is right for which I need to give the value select 1,2,3 to a case selector, so I finish the task. you got my point?

  Thanks for the reply

• A generated within a loop in a subvi output data can be transferred to the main program for each iteration of the loop?

  Hi LV users,.

  I have a very basic question, I have not succeeded to asnwer using basic considerations.

  I made a sub - vi that performs a scan of current-voltage using a unit of measurement-source Keithley and a loop FOR.

  The subvi outputs 2 tables with my data (essentially an array of voltage and the corresponding current table). I also defined a Terminal at the exit of a group of these 2 tables in order to plot a graph XY - output. Specifically, I indexed this cluster to update after each iteration of the loop FOR, in my sub - vi (the indicator is placed outside the loop, of course).

  My problem is that I want my main program to display the XY-graph in real time, with an update after each iteration of the loop FOR which is in my sub - vi.

  I have a problem because my sub - vi output terminals are available for the main program concluded as soon as the sub - vi has completed its own execution (which is what we expect of sub - vi to do).

  How can I use a sub - vi (because it's handy) and get in the main program in the course of its performance data that are generated from the loops of sub - vi?

  Thanks in advance for your help,

  Yoyo87

  Elements of the queue in the Subvi them put your main VI where you want to display the data and the.

  It is similar to the architecture of producer/consumer. There are examples of it in LabVIEW. The examples work with 2 parallel loops, in your case a loop (the producer) will be in the Subvi.

• Graph waveform repeats with each iteration of the loop

  Hi guys,.

  I got some great responses from you many already, so I hope you can help me once more!

  I try now to simply take a voltage that is measured by a sensor, I tied to AI1, and I built a graph of very simple waveform using a DAQ assistant. I have the setup terminal to CSR, the acquisition value continuous sample mode and read samples and rate game to a control on the Panel before which I can control myself. All this is a while loop that is needed to collect data over time.

  However, the problem I have is that for each loop of the loop, it seems, to reset the graph, so my x-axis never increases over time, ideally I want it to do is to show results through from 0 to 100 on the x-axis to say, and then, when it comes to 101, he will start again on the extreme left of the graphic to the right to a crossing another 100 points given) (there's a term for this, but I forgot, sorry!). To be honest, this kind of logic like everything in the loop will be restarted, but after trying to chart the loop it does not work, so I'm fresh out of ideas.

  I think I might have to do is to manually build segments of data acquisition (DAQ mx) and have only certain parts of them in the loop, although I can't be sure. I tried various examples and online on the database of NOR (including tension-int acq & graphic clk which works well in the examples, but not at my request) but no luck for now

  If anyone can think of what could be the problem, then please let me know. FYI the sensor is optical fiber if it makes a difference. I have attached the file VI that I did does not really...

  See you soon!

  Since you use a chart there is no way to fix it. If you choose to go to a XY chart you could solve this problem. See the example below.

  

• How do you give each iteration of a loop IF %

  Subject: Send a signal to step to a stepper motor driver at regular intervals.   My first try to use a loop was a failure because the data is only passed on a loop when the loop ends.   Instead this application requires the data to be passed on a loop on each iteration.

  What happens if changes can be made to a loop for output at each iteration?  Or, if a loop is not suitable for this application which is preferable?

  Howard

  A loop looks like a reasonable approach. But you will have to send the signal to each iteration of the loop, then talk to the stepper motor inside the loop on each iteration. You can also think of calendar of loop (how fast you want to send commands to your engine) and stop the loop (for example, the user clicks on a stop button).

  Another concept, you can familiarize yourself with are state machines. LabVIEW courses cover these, and there are many messages about the machinery of State here on the forum.

• How the entry changes with each iteration of the while loop

  Hello

  can anyone explain (clarify) to know how or what contribution will be fed like the d block of adaptive filtering for the first, second entry (n) and remaining iterations of the while loop as shown in the picture as an attachment...

  As I need to feed the e (n) out of the while loop as input d (n) to the Adaptive block for the first iteration for the next iteration of the previous output e (n) of the block Adaptive must be fed back as input (n) d and other x (n) of entry form the DAQmx.

  Thank you.

  You have a shift register on the edge of the loop, so for the first iteration, the input (n) d will get everything that feeds the shift register on the left of the outside. After that the adaptive filtering performed, e (n) is injected in the shift to the right, register to be read from the shift register on the left on the next iteration. And so on. This seems pretty much what you want.

  If you need retain the value in calls, use a node that is initialized in the world of feedback to feed out of the while loop at the entrance.

• How to save a graph after each iteration in a loop for?

  Hello

  I wrote the code that initializes a spectrometer. Once initialized, if the "Capture" button is pressed, the spectrometer takes a new spectrum three times (see loop for) every second. This spectrum is shown as a diagram in my front. My code works fine... it will update the spectrum every second.

  However, I would like to be able to record each of these three iterations in the form of separate graph. Basically I want to click on "Capture" and have my code to save three graphics to a specified folder. How can I do this?

  I have attached my VI.

  Thank you.

  Probably the easiest is to take the data of the for loop and pass out in a tunnel that is indexed.  Manipulate the resulting data table you want.  You could also do a producer/consumer and write files as the data comes out.

• How to reset a variable after each iteration of a loop?

  Here's the code if you need to see. 'fact' is what I want to zero whenever the factorialN method completes. Thanks in advance.

  What is the problem? Declare the method as "int" instead of "void" and the return value.

• How to add items to a table 1 d with each iteration?

  Hello

  I have a 3 loop iteration For which gives a table of 5 elements after his execution. At each iteration of the loop, how can I add each item to its previous value to form a final picture of the cumulative sum of the parts? For example:

  Array of values for 1st iteration: [A, B, C, D, E]

  Array of values for 2nd iteration: [F, G, H, I, J]

  Array of values for the 3rd iteration: [K, L, M, N, O]

  How can I make the Final table being a cumulative amount of IE: [(A + F + K), (L + B + G), (C + H + M) (D + I + N) (E + J + O)]?

  Your help will be apreciated, thanks!

  The Add function is polymorphic. So, if you give 1 2 tables you will get a table that corresponds to the sum of each item. With a loop, you must use a node registry or feedback shift to keep track of the sum of the currents.

  For example:

• loop nested using iteration of the outer loop as counter

  Hello world.  I have a moment where I perform calculations at each iteration of the loop and display on the front panel.  Then, in a loop iteration randomly (referred to here as I = 9 to test) it fires an event where that performs calculations on x number of iterations (iterations of the outer loop while) the result of external calculations, while performing at the same time and the view from the outside so that the calculations of the loop.  Is that two mathematics algorithms are synchronized in iterations.  After x iteration the program returns then to only calculate and display the while loop calculations using the value from the shift register, updated until another event is triggered (I do not show an another event trigger in the code example) I can just find a way to trigger an event , and at the same time to make two calculations with the same loop iterations.  Any suggestions?

  The VI of the sample in the previous post of crossrulz should provide the functionality you are looking for. The while loop acts to go through ten operations you want to perform and records time difference will allow him to record these values, as you understand. I think that crossrulz refers to shift registers on the while loop that surrounds the case structure that records the shift are unusable on a structure of the case, as you pointed out.

• Difference b/w reading synchronous file and read the file adapter Service

  Can someone tell me the difference between synchronous file read the service and the service of simple reading of the file adapter functions.
  
  where exactly do we use the synchronous file service? Please give me some example of scenario where we can use file synchronous read characteristic of service...

  Synchronous reading is used for playback of files mid process. People tend to use for consuming files based on a business rule. You can specify which files you want to read. An example of this would be an an email is sent telling the faile abc.csv has been downloaded. The BPEL process shuts down gets it. You can also cheange the location of the file dynamically in the process as well.

  Using the file adapter is used to call a process so when a file is placed in a place the BPEL process is called. It is most commonly used.

• How insert elements into a table after each iteration of a for loop

  I'm new to labview and work on an application where I'm supposed to store an element in an array (without crushing) after each iteration in a loop for. I tried using function Array build, keeping the flag outside the loop for and played with indexing, but did not work. Please suggest me an idea how to do it.

  Thank you

  It would be better if you attached the real VI.

  None of your images show an operation 'insert into array.

• 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);
