• 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.

• plot update after each iteration

  Hello

  I have an example of data code where I collect data on different devices.  Can you help me to update "GRAPHIC 2" to display all of the plots on this graph."  However, I would like FIGURE set 2 updated after each throw outside of the loop.  [After the 3rd iteration of the outer loop (defined by "outer loop"), "GRAPH 2' should therefore 3 plots and so on..."]

• 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 upgrade a table after each iteration?

  Hello

  I have a vi which works fine but the problem is that it updates all the data once the vi stops running. I want something as soon as (for outside for loop) 1 iteration it performs updates the table in front of the Panel, then 2nd iteration, it updates again and so on. Can anyone help me please with this.

  Thank you

  In fact, in your case, there are a simpler way to do it... If we talk about the pink channel on the first loop indicator.

  Just move the table from outside the loop inside the loop indicator.

• reset the graph after each race

  Hello

  In attachment VI, I am trying to collect data to interverals (in seconds) and display them in a chart that updates after each iteration.  However, I like the graph to be handed over to zero just before starting a new would go program.  In the current state, after the end of the program, the graph just seems to add data and continues on.  I would like to have the x-axis as time.  In the current state of the program, I wait 1 second, take the data and so on.  I would like a parcel of time data vs.  So in the attached VI, the graph must finish 20 sec.

  Honestly, I'd appreciate any help to determine my dilemma.  I'm under LabView 8.2.

  Thanks for all your help and your time.

• 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.

• State machine with acquisition different modes/loops

  Hi all

  I did a machine design to State (as described here) to organize three (mutually exclusive) process / States: idle, measurement of calibration and continuous measurement. Calibration must be performed before measurement, because the result of the calibration is used for measurement. The data entry is a camera that should run continuously, also in rest mode.

  The problem however is that this state of calibration and continuous measurement (should) have another method of data acquisition. The measure is continuous and the images are processed in real time. To calibrate a number N of images should be accumulated and treated (simply create a background image).

  In the state machine as I have now (see attached image), I have the acquisition of vision outside the state machine in order to have a live view at any time. The problem now is that the inner loop in the State of calibration (the loop that must accumulate the framework) accumulates of course that the first framework N times, it is not question for all new managers during this State.

  Of course, I could fix this with an if/else statement in the first calibration mode accumulate images (if I< n,="" accumulate="" frame="" in="" buffer="" and="" continue),="" but="" i="" am="" not="" convinced="" that="" having="" a="" lot="" of nested="" loops="" is="" the most="" elegant="" way="" to="" do="">

  This also got me thinking, is the state machine, as I built it here all the best way to manage these two processes/acquisition modes? Or are there better ways to do this?

  Contributions and comments are very much appreciated!

  Note: I know that loop as scheduled now in State calibration is wrong with shift registers. It was a test before I realized that the fault was in the interweaving of the state machine altogether.

  Please do not attach pictures, but rather post executable code, screws (easier) or as extracts from LabVIEW (which became the screw when you drag in a block diagram).  If you have more than three attachments, compress the folder and attach the ZIP file.

  I was once describing a system similar to yours, and one of my students, who was a computer science major, said "it's not a State Machine."  I had a similar situation to yours, where I had a procurement process which took time and a 'Stateful' routine that does different things with data (in your case, use it for calibration, waiting to 'Go', absorbent, etc.).

  I understood that it was correct.  I ' D 'opposite' model, with the Acquisition, always running and "driving", the calendar and make 'Appropriate Action' on each set of data, where the Action could (and did) vary according to other conditions.  So I renamed my state machine 'Action engine', and everyone was happy.

  So I won't bother looking at your code (a quick glance showed me that I have only would be frustrated by the limited view), but will give you a suggestion for an alternative architecture.

  You want to (ideally) two parallel loops.  A single loop simply acquires the data (images) at some rate.  For each Image, it signals the loop else it's time to 'Action' on the acquired data (to do this, use a queue or the notifier).  You want that engine of the Action to perform independently the Acquisition loop, just in case a particular Action takes, say, 1.2 times sample to complete - you don't want 'Miss' samples!.

  The loop of the engine of the Action is a unique, appropriate Action at the time, on the newly acquired data.  If you are in the 'State' calibration, the Action will be "add to the calibration.  When you have accumulated enough data to do calibration, set the following Action to (for example) 'wait to start the Signal.  When you receive the Signal to begin, take Action to "acquire, process and save data.  And so on.

  As it happens, I did my code exactly in this way, but it was the idea General - Acquisition was the 'King', he ran the clock and led the ' Machine/Action State engine' to 'do the right thing, appropriate to the time' with the data.  See if this type of model is appropriate in your situation.

• Appellant States in a state machine more than once

  Hello again,

  Is there a way to call a State in a state machine after that he ran already? In order to develop, I have a program that will put pressure in increments of 20% and will then write to a file. Once it is done with the rule of higher pressure (100%), I want it repeated the test, but this time in decrements of 20%. So it will do:

  1. set the pressure at the lowest point

  2 meter to read and write the value

  3. set the pressure at 20%

  4 meter to read and write the value

  All the way up to 100%, then:

  5. set the pressure to 80%

  6 meter to read and write the value

  7. set the pressure at 60%

  8 meter to read and write the value

  All the way to the lowest point.

  Is there a way to do so instead of making a State for reading and writing to each percentage? In this way I haven't read Agilent 20% increment, Agilent read 40% increment, etc..

  I have attached the code to explain what I mean.

  Thank you all, still a newbie

  
  

• VBAI 2012 "save the image calibrated to the file" issue

  Hello

  Under the State of 'Calibrate Image', 'Save the image calibrated to the file' option does not work correctly.

  With the exception of the type 'Point of Distance' of the calibration, the new image is ever recorded. I checked the calibration image .cal2 in the folder \ProgramData\National Instruments\Vision AI\Calibration Builder, each iteration the meta-data are updated but not the image.

  I have a camera calibrated with a grid (see picture) and using the model of the distortion. Working remotely can sometimes change and I need to take a recalibration. This step should be as simple as possible. Example: put a model calibration in the field of view, then press a button recalibrate.

  The problem mentioned above, it is impossible. Whenever I have to manually go into the choice of the State of the Image calibrate and update the calibration image myself. Otherwise, calibration is recalculated from the original image which is not best suited for the new working distance.

  Is there an easy way to make VBAI save a new image of calibration with each iteration?

  Or is it something that I did not understand this option 'save image calibrated to the file?

  Hi Larpin,

  Unfortunately VBAI does not support the suggested behavior. The best solution in my opinion would be to implement your application completely in LabVIEW!

• 2 parallel state machine

  I have 1 state machine controls a number of sensors of pressure and balances.

  The transducers of pressure and the balance is used to analyze soil samples

  I need an another State machine of the exact type as well as others. The only difference is that the new machine of the State must control another set of sensors of pressure and balances.

  2 state machines must run parallel, then I'll be able to analyze soil samples 2 at the same time.
  The State machines need not run at the same speed. It's alright that the computer of a State is ahead of the other.

  Is there a clever way in LabVIEW to get over this, or do I just copy the first state machine and change the id for sensors of pressure and balances?

  Reentrancy is the key here.  I recommend using prealloue reentrancy Clone for reasons of speed and memory management.  If you made an a high level VI which simply calls this State twice, machine in parallel.  Pass the ID to the state machine and you have two running.

• BatchModel - 10 loops and save the test report after each complete loop

  Hello everyone,

  We are using TestStand 2010 and currently using the BatchModel.seq for a quantity of 4 four DUT in a configuration of Burn-In.  Ten 10 times in a loop sequence of customer.  I wonder if there is a way to save the test at the end of each loop data report and create a new one for each of the loops after that.  Is this possible or I asking me too many software TestStand?  Thanks in advance for your responses to this last post.

  Kind regards

  Scott

  Hi Doug,.

  Thanks for the reply.

  I will discuss with my colleague who had a hand in the development of this customer file.  This customer file has been developed mainly by a contractor who works for our client.  These sound options as they will do the trick.  The customer file is used to Burn-In, so there are three levels of testing at three different temperature levels.  We strive to find some possible bugs in the code to that contractor that blocks the client file and all data is lost.  This will at least give us some options of data collection in a way that we should not worry if there is an error during the process and at least keep some data.  Thank you for your reply and if there is anything else, with that we have trouble, I'll post again.

  Kind regards

• Snapshots - how to save the State of the machine before deleting

  Hello

  We have a production VM on a cluster host ESXi5, which was taken earlier (nearly 2 years?). Of course, I want to get rid of the snapshot that he shouldn't have spent so long, and after some research, I'm pretty sure deletion will do what I want (I want to keep the virtual machine, as it is now with all the changes since the snapshot).

  However, I also want to take every possible precaution before to do this because if the changes are cancelled (i.e. if returned to the State of origin before the change), it will create a good amount of work, and I want to keep the virtual machine, as it is currently before deleting the shapshot.

  Is this possible? I read cloning will not clone the snapshot of the files themselves, but the cloned VM will contain changes since shapshot has created or will it be the VM before the snapshot? If the clone itself is a copy of the current computer running (changes since snapshot included), this could be an OK option.

  I don't think another solution could be to stop the VM and copy the VMWare real files somewhere - would this work?

  I am probably being a little cautious with this, but I'm a little nervous about snapshots and I want to make sure that I have all the bases covered... just in case...

  The virtual machine is saved so as a last resort I can restore from a backup, but I would rather avoid this path if possible.

  See you soon,.

  Tim

  This snapshot that one is associated with your virtual machine, which is 2 years old?

  what you think is right about removing it. If you just run this snapshot delete operation, it will merge delta with basic disk (since you instant is very ancient, the size of your delta is probably very much, in this case, this operation may take up very much time to complete) and resulting VM will be your last VM with all changes made after this snapshot was taken too.

  At the time of the snapshot, Deleting, you must also remember that there should be enough space available in your data store where you VM resides, if possible to reach downtime, then make the deletion of the snapshot while VM is powered off, or try opening the process during off-peak hours.

  I'm sure you might have encountered following KB already as you have done enough research on the topic

  VMware KB: Delete all snapshots and consolidate Snapshots feature FAQ

  I read cloning will not clone the snapshot of the files themselves, but the cloned VM will contain changes since shapshot has created or will it be the VM before the snapshot? If the clone itself is a copy of the current computer running (changes since snapshot included), this could be an OK option.

  Cloning will also do the job. Yes cloned VM will be for blocks of basic disk and disk from Delta and merger while then resulting VM cloning will be having only basic disc with all changes that you made after the snapshot.

  I don't think another solution could be to stop the VM and copy the VMWare real files somewhere - would this work?

  The virtual machine is saved so as a last resort I can restore from a backup, but I would rather avoid this path if possible.

  Keep copy of all the files in this virtual machine a safe, desirable for you, but at the same time if you have the frame of this virtual machine already successful backup made so nothing to worry. Your virtual machine can be restored from that successful return. If you want to test the restoration, why not restore you this virtual computer on an isolated network and not little a test for your complete satisfaction before proceeding to deletion of snapshot.

  Note: Do not operate upgraded, this will put your VM around 2 years back State at the time of the creation of the snapshot.
