Is there a BodePlotter on LabView?

Hello,
I use LabView 6.1.
I want to measure a Lowpass with the analog input.
Can I indicate the whole frequency spectrum (for example from 1khz to 10khz) in dependence of the amplitude? Is there something like a Bode Plotter?
Thanks

Is there compatible motion driver for LabVIEW 8.6?

Is there compatible motion driver for LabVIEW 8.6? The latest motion driver seems to be 7.6 and it only support up to LabVIEW 8.5...

If you buy LabVIEW 8.6, you will also get 2008 August Driver CD.
NI-Motion 7.7 driver should be included in it.
Or you can wait for a while.
I guess NI will put on Web these days.

Is there a way to interface Labview Web GUI with Fusion Charts?

Is there a way to interface Labview Web GUI with Fusion Charts for dynamic web presentation?
http://www.fusioncharts.com/

I have a ballistics program which our clients can use (see attached). Basically there is a series of Cascading Combo boxes that the user must select for Bullet Manufacturer, Caliber, and Bullet ID. The program then goes out to the relevant data file (.CSV) and provides ballistic inputs for the selected projectile. The user is also required to enter in additional data, such as Sight Height, LOS Range, Temp, etc.. Once all data is input, the user either hits the Calculate Button or the Tab (I'm using Event Structures and I now realize this is an issue for Web UI Builder), and the data gets passed to a MathScript which then crunches numbers and spits output to fill a table and a series of Graphs based upon the tablulated data (if so desired).
I was hoping to use Labivew for the first two parts ( Data Collection and Number Crunching) and use something like Fusion Charts for the presentation. I tried learning Ruby on Rails. I was successful with the Ruby part (basically the Mathscript portion) but really got hung up on the Rails section and the need for something like JSON to interface with it. Could not find a useful source of information which really showed you how to combine the two effectively.

Is there a way to make labview messages always appear on top of all windows?

I have a main VI running and a user selects a non-Labview window to work on. Is there a way make the user prompt or user input express VI messages appear on top of all windows? I have experimented with the "make window always on top.vi" from the NI website. That brings the VI that is running to the top but not the prompt for the express VI message. I have also used the "make window always on top.vi" in a sub-VI and called that sub-VI to be always on top and it works. I was just wondering if there was a way to do it with the express VIs that NI already has written instead of making a custom message the way I have mentioned.
Thanks,
Troy

If you only need to display a prompt and can get by with a limited set of canned buttons (OK, Cancel, Retry, Continue, etc.), you can try a VI that calls the Windows API MessageBox function. You can display a message box with user-defined title, text and buttons. There is an option to use the system modality which is what you want in this case. I use my own version of this all the time for that very reason.

Is there a .sld file for LabView runtime engine when creating Embedded XP image

I'm looking for a .sld file to aid inclusion of LabView runtime engine in my embedded XP image. Has anyone already written one?

Hi,
unfortunately, National Instruments doesn't have any sld files for embedded OS'es, however, please checkout the links from the Lookout discussion forum, where someone was trying to do something similar.

Are there any packages compatable with LabVIEW to make the program CFR21 part 11

Hello All,
Are there any packages that are compatable with a LabVIEW program, which creates a .csv file, that would make the program CFR 21 Part 11 compliant?

A quick search of Google for " cfr 21part 11 labview" returns several links.

Is there still a list of LabVIEW tips and tricks on NI's site?

There was such a list there a couple of years ago, but I can't seem to find it on NI's site.
Anybody know where it went?

The LabVIEW documentation team tried to collect information about how people used the Quick Tips in another discussion forum earlier this year. I believe they took the information they got back and decided to incorporate the Quick Tips into other LabVIEW help topics. However, the Quick Tips still exist for LabVIEW 8.0, and most tips are generic enough to transcend versions of LabVIEW.
If the Quick Tips are something that you would like LabVIEW to include in future versions, please make a product suggestion, so that they can be aware of the interest for this feature.

Are there large performance gains in labview with a dual processor?

I have an application that is very cpu intensive using 4 ni6052e's with lots of data aquisition going on. Does anyone have experience with dual processors and labview? What processors? What OS? What are the complications to switching?

You might be interested in the following documents:
Using LabVIEW to Create Multithreaded Applications for Maximum Performance and Reliability
Optimizing Test with Multiprocessor Machines
LabVIEW and Hyperthreading
You'll want to look at multithreading along with multiprocessing. On multiple processor systems, multithreading is almost always beneficial, because it allows for each multiple i
ntensive threads to run simultaneously. However, it is the operating system's responsibility to schedule threads on the processors, and may not always schedule the threads of your application on separate processors.
On either single or multiple processor systems, there is often a benefit if you are sharing time between CPU-intensive threads and I/O-intensive threads. While one thread is reading or writing to the network (or GPIB, or hard drive, or DAQ device) other CPU-intensive threads can keep running. In a single-threaded system, the CPU would sit idle at times, waiting for the I/O to complete.
Hope this helps.

Is there a sizeof() vi in labview?

I would like to get the size (in bytes) of various labview data types. Is there i vi which will do this? I can't find one. It seems flatten to string followed by string length does the job, but its a of shame having to create a string just for this...

Hi Pawel !
That works...except if you try to wire a cluster containing a string !

Is there a way to use Labview for Linux for IBM AIX 5.1.

I think any application built for linux can run on the AIX 5.1 if the application is recompiled on the AIX 5.1. So theoretically NI can just recompile there Linux version of Labview on the AIX 5.1 and it will work. Is there a possibility that NI will port Labview for AIX 5.1.

I think that the use of LabVIEW for linux is platform independent as far as hardware. I believe that as long as you are running a compatible GUI (I believe XWindows and KPT??? are two that are recommended - check ni.com/linux for more information. So, for your purposes, as long as you can install the proper GUI, and then LabVIEW for Linux, you can then run, code, compile, and deploy applications on the AIX 5.1.
I am personally VERY interested in knowing about your success (or failure, should that unlikelyhood occur) on Linux. If you browse the topics, there is actually one on non-windows useage of LabVIEW. I am currently setting up my first Linux machine at my home office, and am very curious to know how other people do with this 'adventure into unc
harted territory'. The only documented useage I have seen is in Gary Johnson's newest edition of Power Programming.
Good luck, and please keep us posted. I sense that I am the only LabVIEW for Linux fan besides yourself. But please feel free to post to this thread, and to the topic.

Are there any issues regarding running Labview on Windows Vista

I am a cognitive psychology graduate student, and I am considering switching to LabView to display stimuli and gather RT data. I have previously used E-Prime for this task, but E-Prime doesn't seem to run well with Windows Vista. Are there any known issues regarding running LabView with Windows Vista?
Thanks
Chris

I've had no problems on Vista*. Only issue I've had was concerning how Vista uses fonts, but if you start on Vista and don't switch between XP and Vista, etc., then you'll be OK.
*no problems with LabVIEW's compatibility with Vista. Now, Vista in general, that's another story and not for this thread/forum.

Why are there no advantech drivers for labview by ni ?

the advantech drivers do not integrate well in labview. The VIs provided by advantech are not direct equivalents and neither do they have the same features. I need some help on this.

Hi PC
I am using an Advantech PCI-1713 card and I was just wandering how your program is going because I am having difficulty with mine and was wandering if you would like to help each other out.
I am trying to measure 16 channels using one of there sample VI, I think it must be the same as your Multi Channel Interrupt VI you described in your message.
I have a question, how do you get it to save more than one cycle because mine is only saving one cycle and I do not know how to fix it.
For example if I enter COUNT = 100 then it will only save 100 samples. How did you get your VI to continue saving samples???? I also am using Cyclic.
I am new to DAQ and would like any help if possible
I have attached the Vi and an example o
f what I am getting.
Cheers mate

Does there exist a .mat-to-LabVIEW converter?

I need to be able to read from and write to .mat files from within LabVIEW. The .mat file format is what Matlab uses to store arrays. I have found that The Math Works offers a C library with functions for accessing .mat files. I suppose I can use this library to create a .dll (or use CINs). Is there a software utility currently available to do this?

This isn't a convertor, but you can reuse Matlab from within LV. LV5.1
I think, added the script node. You can type in or popup and import
matlab scripts. At runtime, the script contacts a Matlab EXE to have
the computations performed and to return the results into LV.

Is there any block in the Labview similar to that of clock block available in Matlab ?

Hi guys, i have generated a pulse in the matlab using the embedded block having some code in it and it takes the clock as one of it's input as shown in the figure.
Now i want to do the same in the Labview, but here i need a block which is exactly similar to that of the clock block used in Matlab.Kindly reply at the earliest. Thanks in advance.

The function you are looking for is available in LabVIEW Control Design and Simulation Module:
http://zone.ni.com/reference/en-XX/help/371894G-01/lvsim/sim_simulationtime/
This module is part of the Academic Version for LabVIEW.
Also, notice that your code from the competitor software has a 'implicit' loop around the formula node, which you can also do in LabVIEW by using:
1. Control and Simulation Node
2. Place it inside a simulation subsystem
3. Not using the Control Design and Simulation Module and using a For-loop around the node and controlling the time-step using index control (the 'i') and using multiply by a constant to simulate time. All this is abstrated inside the control and simulation loop, though.
One more thing... if you have the Module, look at the shipping examples under:
C:\Program Files (x86)\National Instruments\LabVIEW 2013\examples\Control and Simulation\Simulation
and look at the folder Utilities and Signal Generation. You should find those example exactly what you are trying to do.
Let me know if you have more questions.
