• How can I autoindex looping for to create several channels daqmx

  I'm trying to autoindex create a loop FOR containing the DAQmx vi to create AI multi-channel voltage with identical settings, except that I need to apply specific channel names using a constant and specific physical channels using a constant of channel. Wiring of a constant DAQmx of physical channel does not work because the data type is incorrect. Similarly, I don't understand how to use a string constant to autoindex through the channel names is or how to configure the constant string (s) to assign names. Also, when I try to make one of these, I get a tunnel to exit the DAQmx autoindex create channel, rather than a task out. I can achieve my goal using several explicit DAQmx create calls to channel, but for high channel count, it is very time consuming.

  I use LV 8.5.

  I'm hoping to find the code showing how to perform the conversion type, flattening, or what to do.

  I have an array of clusters.  Each element of this array is a cluster.  The cluster consists of a (scalar) string and input/output (also scalar).

  In addition, my TI attachment extracted.  I think that your file has been LV2009.  If so, you can drag the image from the browser and drop it onto a diagram.

• How to stop a loop "for".

  Hello

  Do you know how I can stop a loop for? because when I click on the stop switch on my front, the VI didn't stop and continue to perform the loop.

  If you have a newer version of LabVIEW, you can right click on your loop For and show the terminal stop.  This will allow you to stop the execution of the loop For the earlier that you would otherwise based on the N or the number of items in an array of automatic indexation.

• How to make a loop for

  Well, I have a problem I do not know how to solve.

  The idea is simple but I have no idea how to implement it on LabView. Here it goes:

  I start with a picture of a [i]. For i from 1 to 5, I initialize all values to zero. I want to build one because I have 1 to 5 that loop for each iteration replaces the value of a [i] EI with i.

  Maybe I'm missing something but I don't know how to do. I would appreciate it if you could give me some advice.

  Kind regards

  Can be done this way.  You don't know why you must initialize and then replace.  Much easier to create just using autoindexing.

  

• How to export an image animation that loop for a certain period of time?

  I created a sequence of animation images with 6 photos chaque.12 seconds time and I put it for playback 25 times but when I export as a quicktime that it reads only once. How can I make the video loop exported 25 times?

  As far as I know, the only way to get in the gif / png is to repeat the executives making the size of the largest file 25 times, which is obviously not ideal.  But you might be able to control the number of loops in the application that you use to play the animation.  For example, I think you can do that from PowerPoint.

• How image rotation and displacement by using different origins

  Hello
   
  I use LabVIEW 8.5 and 8.5 of Vision.
   
  I need to rotate, scale, and move a 2D image regarding one aspect of the image. I use IMAQ turn and shift, but I don't know what is the point of reference or originally used in this function. The coordinates of the image is very important in my application because I need these details to complete the recording of the image.

  My question is as below:

  (1) the origin (0,0) of an image is located in the upper left corner, can I change it to the center of the image?

  (2) how can I specified a certain point (coordinated) as a reference for the rotation and scale?

  Your help is very appreciated. Thank you.

  Hello

  Thanks for the idea, I'll try it soon.

• How to run a loop for 1 hour

  Hi all

  I am very new to labview and its components. I want to program a loop running for an hour.

  In fact, I would like to make it more user-friendly, by asking the operator to enter it here how long to run the code.

  Can someone offer me please how to do this?

  Please excuse me if I entered the wrong forum...

  1. go in show results
  2. add Pivot view
  3 delete the view table and all other views that you have previously
  4. now you have the title and the Pivot discovered in the Layout is dedicated to the
  5. it displays only Pivot view with title.

• For parallel loops run on hearts of dedicated processors?

  I don't think that this is the case; My confusion is due to the fact that the literature regarding this structure addresses using the maximum number of cores the computer in which this codemay run in the dialog box for parallelism but also loop iteration using the CPU Information function to determine the number of instances to parallelize. I suspect that parallel loops For will first of all be decomposed into Tufts/tasks of iteration which will be either in versatile collaboration & and/or multithreaded in a system of priority of execution before they ever get to be mapped to hearts dedicated instance. Is this correct? -literature, I want to talk about is Improving Performance with loops parallel http://zone.ni.com/devzone/cda/tut/p/id/9393, under the guidance of Performance or the help of LabVIEW (multiprocessing and Hyperthreading in LabVIEW). I don't see how this information applies to how the loop bodies parallelized and executed. I hope someone can enlighten me and perhaps others to read these documents.

  Thank you!

  jorgeinSD, thanks for the insightful question. Your second option is correct. Each instance of a parallel loop is in a different bouquet and schedules of delivery system of these Tufts between the available threads. LabVIEW does not bind son to cores for the parallel loop, so threads can switch between the nuclei they run.

• Create a table in a loop 'for' (reset the number of loops)

  Hello

  I try to incorporate a signal of acceleration from an analog input CRIO to get speed and then further integrate to get the moving of a vibration system.

  I understand that to achieve integration, a table must be fed in. My problem is that I could not buffer the signal in a buffer block, as I couldn't find buffer blocks. so I decided to create my data table by using a loop "for". The nests of the loop 'for' inside a timed loop. The problem that I'm stuck on is how to reset the loop 'for' in order to fill the buffer with each iteration of the outer loop timed.

  I enclose the code if that helps. Note that I use labview in 2013.

  If anyone who has encountered a similar problem before can help me, I would be gratefull.

  Concerning

  Ali

  You can use a shift register initialized as inputs to your curls, to build your table of one. However, you realize, don't you, that the execution of your program as written loops as soon as the computer can spit out responses, then the output array may contain several points that took place before the entry has updated? Assuming that your thing cRIO (I've not worked with these) has integrated into its routine acquisition of calendar data, I suggest you put that inside the loop to get a data point by reading.

  And do you really want your graph to distance for update only every thousand points (points of acceleration million) speed?

• How to create parallel tasks using parallel for loops

  Hello

  I'm going to put in place a program that communicates with the six logical controllers and must read the status of the system every 100 Ms. we use OPC datasockets for this, and they appear a bit slow.

  I created a uniform method of comm. for all controllers, and now I find myself this method of programming six times to communicate with each system. I was wondering if it could be done more elegant using the parallel for loop, in which case I program an Exchange once and then six workers running simultaneously. Since a picture is clearer than a thousand words, what I'm asking is:

  Is it possible to replace something like

  

  by

  

  and that for performing these tasks in parallel loop (on different cores / in different threads)?

  I have configured the loop to create instances of the 8 to the compilation, so I would 2 surplus available when running instances if I find that I need an additional system.

  The benefits of the Show method in the second photo for me are:

  * takes less space

  * changes need be made only once

  * less blocks, son and other things makes it clearer what is happening.

  * flexibility of the actual number of tasks running (8 available runtime instances)

  * If multiple tasks are necessary, I need only update the maximum number of instances and recompile, i.e. no cutting and pasting necessary.

  Unfortunately, I don't have these available system yet, so there is no way to test this. Yet, I would like to know if the above works as I hope - unfortunately the help of labview is not quite clear to me on that.

  Best regards

  Frans

  Frans, the parallel for loop will work as expected in this situation. The six tasks will run simultaneously in different threads. What part of the aid could be made clearer?

• parallel processing: for loop taking place

  Hallo,

  I have a loop 'for' runnin on this system: LabVIEW2009, windows7, intel i7.

  I wonder if and how I can tell to LabVIEW that he would be allowed to run different iterations of the loop at the same time (concurrently) on my processor with 8 cores.

  Now, it will execute the next iteration when it ended the previous, even one so is there no dependencies in iterations.

  I want to give a 'ownership' of the loop, which means that it can be "unfolded" for parallel execution.

  Thank you

  Pier

  pop up on for loop and select "configure interation Prallelism."

  Activate it.

  Wire a certain number to the new 'P' of entry to specify how many processors to spread it everywhere.

• How to get the items on a loop at the same time during the execution of the loop for

  Hello

  I am a student. I would like to know how to get the outside loop counter values For in parallel so that the loop runs rather than obtaining the value finally outside the loop for future prospects for the answers.

  You already said yes, and you have said some of the different ways (registrants, locals, reference, queue, etc.). Since the information was provided to your request, the thread can be considered closed? If you want details about how to implement something, you must provide the details on what you are doing.

• How to stop a flat sequence (or timed sequence) which is inside a loop for

  The problem is this, I have a loop that repeats 10 times and inside this loop, I have a flat sequence (or timed sequence) with four images, each of this chassis to evaluate a different condition of a vector that I introduce.

  What I woud like for example is:

  I'm a fifth County of the loop for and in the case that part 2 does not meet the condition, the sequence of dish (or timed sequence) stops and starts the loop again but this time for the number of number 6.

  I would appreciate your response.

  You can't stop a sequence structure.  This is how they are made.

  What you should consider to get rid fo structures sequence and to change a state machine architecture.  There are many examples in LabVIEW, as well as on the Forums.  The big advantage of the state machine is that at the end of each State, it examines the conditions and determines which State then run. And that is exactly the description of the problem you are experiencing.
