• storage of the data output of while loop

  Hello

  I have a data acquisition system set up to read the couple of a transducer. The output needs to be fed with an excel document, once the program stops running, or when a key is pressed.

  with the current code attached, the excel document is created, but it only shows the most recent series of data. How to make the table to store all the data coming from while loop?

  Ive only been programming with labview for two weeks, so chances are that it is something simple, but please help us in any case.

  JM

  To get what you expect, the Terminal output of table a while loop right click and select the option activate Indexing. Usually if you want to save data use queue to pass data inside the while loop to another loop/VI and perform data recording. For all that you have examples, please do a searc in LabVIEW help > find examples.

• OR 9403: Digital Input/Output slows timed loop?

  Hi all

  I use a loop timed sample of 7 current channels (NI 9023), 3-channel (NI 9025) voltage at 1000 Hz in scan mode and it works fine. However, when I add for 8 output channels of the input/output module digital module NI 9403 for timed loop, CAPAS sampling cannot exceed 1000 Hz. According with time stamp data I wroten in file, it seems that I have in all ten milliseconds, I missed a miliseconds.

  I would like to ask is there a reason for this? The digital I/o module affect the timed loop?

  Thank you much in advance.

  I'm not familiar with the FPGA code, so I can't comment there.  However, I noticed that you call writing to text file twice in the timed loop.  Can you only collect data and then write the files after the time loop?  This would save a lot of time.  For each entry, the program needs to access the hard disk, find the end of the file, add him and return to write on the hard drive.  A lot of your time, especially since the files are getting bigger.

• output to the loop iteration

  Hi people!

  I am trying to use a very simple "loop For" with "16" iterations and Shift Registers starting at '0' and adding '4' on each iteration.

  But I am not successful to display each value in the iteration. Only the final value of '64 "!

  Is it possible to generate the value of each iteration in each loop?

  If this is the case, then could you give an example?

  See you soon!

  
  

• FORTRAN syntax mathscript code

  So I have a set of 2D data (at the moment it is a set of random numbers) I got histogram binning data of 100,000 points in 1000 bins.  A column (column 0) are the values of the intensity of the (I) I am after and the other column (column 1) is the number of these intensity values of which was put in a cell (ie the number of observations, N)

  Now I have to do now is to go through the table in its entirety (IE 1000 bins) and find the maximum product of N * I, where these values of N and I are now Nm and Im respectively (so the maximum product is Nm * Im).

  What I've done is to separate the two columns in separate tables, one for the intensity and a number of observations.  The best way I could think to find the maximum product is now using the Mathscript node.  I have a Fortran code that already has, it is indicated here.

  Normal 0 false false false MicrosoftInternetExplorer4 / * Style Definitions * / table. MsoNormalTable {mso-style-name: "Table Normal" "; mso-knew-rowband-size: 0; mso-knew-colband-size: 0; mso-style - noshow:yes; mso-style-parent:" ";" mso-padding-0pt alt: 0pt 5.4pt 5.4pt; mso-para-margin: 0pt; mso-para-margin-bottom: .0001pt; mso-pagination: widow-orphan; do-size: 10.0pt; do-family: "Times New Roman"; mso-ansi-language: #0400; mso-fareast-language: #0400; mso-bidi-language: #0400 ;} "}

  nximax = 0

  make 140 ints = 1, 1000

  If (* ints.gt.nximax num (ints)) then

  nummost = num (ints)

  intmost = ints

  nximax = nummost * intmost

  end if

  continue to 140

  (Note that in my node code I changed - nximax NmIm, nummost and Nm, intmost im, num (inst) to N and inst i)

  But I find that when I run the code as I have, it does not work.  I'm not sure that my data before entering the node preparation is correct (I tried to put it in a loop, but he does not like that (he said that the table was wired wrong and probably especially I don't think that I made the conversion from the Fortran code (as described above) appropriate syntax mathscript.))

  I'm so help after here is a double check on my before wiring the data entering the mathscript node (as much as I want to get the product of the number of intensity and observation of each location) and how convert correctly mathscript code fortran codes so that it does the same thing.

  Any help would be appreciated.

  I use LV 8.6.1

  I have attached the man of interest: PE profile # 1(vi)

  and some random data, I put in place.

  Thank you

  Scott

  Hello Scott,

  Your wiring code seems good.  In general, when you work with tables, you should avoid treatment elements in each both loops in MathScript.  If you want to calculate the maximum product of N * I, you can do it with a few simple instructions.  One thing to note is that you want to perform a scalar multiplication of two vectors (N and me) - Note the point before the time.  If you use the ordinary multiplication, it will try to do a multiplication of matrix and returns an error.  If you navigate using LabVIEW for the max function, you will see it can return two outputs: the maximum value and the index into the array where it occurred.  You can use these values to get the desired information:

  [Index NmIm] = max (n. * I);
  NM = N (index);
  IM = I (index);

• cDAQ 9178 simultaneous independent loops counters?

  I have a cDAQ 9178 wherein I am scanning in various mainly analog channels, but also unique sending digital outputs. These tasks are started during the execution of the program and basically scan continuously, filling variables according to the needs.

  In addition to this, I needed to count impulses and the only way I managed to do that work was to begin the task of counter when necessary, and then stop it. This happens at the same time (within a state machine) and works very well.

  Now, I want to add a second counter, which will take place if necessary (same scenario, task of beginning, read the pulses, work stoppage).

  So in summary, I have to:

  Main outputs and analog loop, digital inputs, tasks began before the great loop and continuously, work stopped only after the termination of the program. (works fine)

  Counter task began when necessary, stopped when necessary, of the main inside while loop. (works fine).

  2nd job counter starts when necessary... (I was wondering if it will work)?

  Should it be a problem?

  Jeff

  Hi Jeff,

  I don't think that you will have problems with that.  To test this, I took an example of the meter and it - create two tasks, each using a counter of the device even duplicated and I has not encountered any errors.  That said, the best way to check for your application would be to add a second straightforward and test it.  As long as it works, there is no problem even if your final configuration can be much more complex.

• How to create a chart using two independent loops while?

  Hello world

  I'm currently developing a program for the acquisition of data. In this program, I have two independent, while loops that each output a number of type double with each iteration of the loop. I am able to successfully create two independent waveform graphs (data / time) for each of the loops when placed inside. However, I now want to create a live data xy chart (the output of a loop is x and the output of the other is there).

  I have a problem, that the distinct nature of loops... When I try to extract data outside of the loop (naturally), it is not refresh with each iteration of the loop causing the graph xy does not work in the way I intend. Is there an easy way to solve this problem? If more clarification is needed, please let me know!

  David

  If the two loops are not synchronized, exactly how do you do the xy graph, where each point, by definition, must have a value of each loop.

  1. updated when updates or the other value and combine with the last value from the other loop?
  2. updated on a constant basis with the current value of each loop?
  3. ... There are many other possibilities.

  #2 is the easiest. Simply create a third loop with a reasonable time and graph the two values via local variables. You probably also should limit the history of ranking somehow.

• Time output USB-6009

  Hello guys,.

  I am trying to create a simple VI to generate two outputs analog square with USB-6009. Each output supplies a LED and it is necessary that single LED shines at the time - so when Out0 is active, Out1 is zero and the other way around.

  To get started, I created a VI in which the goods are made manually by Boolean and it works fine (square v1.vi of signal).

  But I need the output to switch automatically after the amount of time given (I needn't of high frequencies, at about 1 Hz). To do this, I changed "square wave v1.vi" in "square wave v2.vi" and set the Structures of the case in an another While loop which would be timed by the wait function (ms). The idea was that the loop internal would turn the output rate of frequency while the outer loop would ensure a continued implementation of the programme. But the reality is very different and my low level of competence (this is my first VI) let me down. Could you please help me out of this? I appreciate all the advice.

  To summarize: The VI must be continuously running program that generates two dependent signals with adjustable amplitude and opposite phases (Out0, when active, Out1 is zero and vice versa.). Signals must be switched automatically to the given frequency.

  Here's a simple flip-flop - while time the loop runs, the Boolean line connected to the digital output passes from true to False to True... with the schedule determined by the time you put in waiting for him (note that you can have regardless of the different times for the true = on and False = off case).  Of course, the life of signal (represented by 'Digital output') 'inside' this loop - you have to put the 1 point 1Line DAQmx VI write digital Boolean inside the loop, or find a way (for example, a queue) to get the data between the inside and outside.

• How can I create a loop with delays in the series?

  Hi all

  So I wrote a Labview program to control both machines. Very simply, one is a source of tension, and the other is a Lock-In amplifier. What I want to do is change the applied voltage, wait a few seconds for the response of GARLIC to settle, then take a number of measures of GARLIC, then those on average and save to file.

  Here is a flowchart of what I mean:

  

  I did it for the most part, but I'm having a little trouble with the delay. VI file is huge, so I tried to make a simplified architecture that shows the basics of what I do:

  

  (The string and the constant matrix constants aren't actually what I use, it's just to illustrate, because I don't know how to make a quick easy space reserved for diagrams... is there an easy way?)

  So my assumption here (and it seems that it is happening) is that, for each iteration more outside of the loop, the first thing it does is start the countdown and start the change applied voltage/etc. at the same TIME, right?

  And then he only goes in the loop of measure LIA once she completed both of these tasks, right? (Please correct me if I'm wrong!)

  Then, how would make a delay after the loop of measure LIA? If what I've said so far is correct, then if I put a 'waiting' in the main loop, I don't think that it works (or at least not be very specific) because he would begin as soon as the iteration, would therefore be cash while GARLIC measured, and so do not wait the right amount of time after the loop LIA was finished (if I even put that it is long enough that it was still underway after This loop was completed).

  Am I correct in what I said?

  What is the smart way to do this?

  Thank you!

  You're right about the order data flow, which is usually the fall of most starting LabVIEW developers.

  To add a wait behind the inside loop, ask a node pending within a structure (the simplest being a structure flat sequence) and add some sort of data flow from the output of this loop to the structure of waiting. This will force this structure will not work until the loop ends.

  That being said, there is a better way to do this. Look in the Simple State Machine with LabVIEW 2012 and more recent architecture model.

  Edit: NIquist beat me to it.

• Improving the performance of the loop

  Morning all,

  I have a loop For, execution of 5,000 times nested within a structure of the event. I parallelization allowed that each iteration is completely indepentant of all other iterations. I am performing an optimization to each iteration. I have several multidimensional arrays as inputs I at the start of the index outside the loop For and then auto-index on the loop. I then accumulate several tables with the results of each iteration as outputs on the loop for run time is between 40-60 minutes, where, as the same code by one of my colleagues using Python takes 10 minutes. Is that what I can do to improve performance? I'm running a quad core, computer laptop i7 with lots of RAM, so not a hamster in a wheel, the code of conduct.

  Thank you

  Paul

  I agree to say that (a) you should zip code (the easiest way is to attach your VI, not a photo, certainly not PowerPoint), and (b) you should not use form nodes if you want speed.  I bet a dime that your code is going to fight many times more.

• You can select a group of clips on the timeline to loop through reading?

  In order to help me learn reading and lessons complex clip I use Premiere Pro to isolate sections of the difficulty of the study. I have independent clips on the timeline laid out in groups, each group marked with color labels so I can review and play only the groups of clips, or "parties", overall, but I would like to isolate each of these groups a little more if I could play each independently "in the loop" so I can still study them independently and isolated from others. Is it possible to do it on the timeline? I know I can score points on the clips themselves in the preview and output screens and loop, but now I would do each set of clips on the timeline in loop in the sections of clips. I hope that I wrote this clearly.

  Put them on a different schedule and those in the playback loop.

• Loop help please

  Hello
  I'm almost there with a game that has traveled fifteen versions of an equation and then make a return based on the answer. I have a small problem that one click has 15 functions click on it and it takes two clicks to the duties to be performed and the correct answer to display. I would pop a loop in the final clickfunction to pause before executing the if statement and the return of feedback. I do not know how to reference the fields of output in the loop for. All output fields must have something in them. I enclose the code for the final control only because that's who I have the case set out in.
  Your help would be most appreciated.
  Thank you

  Thank you very much, which did the trick. I put the final if statement into its own function, delayed it and then allowed the interval as the last thing in the service. He now works like a charm.

• File operation

  Hello

  I find difficulty in the following issue,

  When I'm in a file operation using the method of Queuing for a loop to another loop, I get the previous values measured at the beginning of the file. To remove it, I blush every time in the queue, but the problem remains so please suggest an idea. I use the binary as well as the worksheet for more explanations for the measurement value recording, and when I go to my data analysis using the saving data the problem persists.

  So please help me and if you need more information or clarification of the problem please let me know.

  I'm looking forward for the solution.

  Thanks in advance...

  Hi Sam,

  1. get queue, and the queue of output in both loop?

  You can close the queue wait either in a loop in the loop of the consumer or the producer.

  2 loop synchronization is necessary.

  3. indicator of error to get the queue queue / recessed.

  4 put force destroy real on the output queue function

  Now in my opinion if you use the function flush queue at the beginning on any program this problem should not be triggered because the queue is already at the same level. It's a strange behavior because I develop a dummy VI and try to run code similar to yours and his works fine for me.

• Mapping the table matrix 2D

  I can't try to plot the graph of an output matrix, Sk since a MathScript node.

  The Sk parameter should be a way out of the matrix (12 x 1) with the length of the added step.  I can see that its fate in the form of a table 3D but can not get the graph of the function works.

  What I aim to do...

  I need to draw responses to the 12 line separate items of the Sk parameter over time.  This means that I have to post 12 separate parcels, ideally to be on the same graph with a shift on the value axis for stacking the answers (I'm not worried about the relative amplitudes since I was only interested in seeing the step responses in 12 plots).

  If someone can provide some guidance it would be greatly appreciated.

  Just right click on the tunnel exit SK and select data type "matrix of 1 d, DBL.

  (The way you slice the table at the beginning is crazy.) Why do you want to create all copies of these data for the most part redundant? Simply no autoindex on 2D and table use the table to index resized to five outings and wire the first clue to the final iteration to get five tables 1 d. You must also calculate the value connected to N for the number of columns minus four, or similar)
