Incorporation of Fuzzy Block From Simulink into LabVIEW Through SIT

I am working on a project where I am using Simulation Interface Toolkit. In my applciation, I am using PXI-8176 with a PXI-6070E DAQ card. I generated my model using Simulink in which there is a Fuzzy Logic Control block.
However, when I run my application real time on my PXI 8176 machine, for some reason, the output of the fuzzy logic block is always constant when
it is supposed to be changing as I change the inputs to the block ( I am able to observe my hardware input). I got in touch with the Mathworks people and confirmed that the DLL file generated by the real-time workshop contains the fuzzy block and everything seems to be working well with that dll file. I was wondering if there is any additional step that I have to follow in order to make the fuzzy block work in real time in my real-time machine. Or is there something that I need to do to be able to observe the fuzzy logic outputs?
The steps that I walked through as folows:
1-)I went to build option and the pick nidll.tlc, as I am targeting a PXI
machine for the real-time application.
2-) I built my appliciation using Real-time workshop.
3-) Then I opened Labview program to generate a user interface for my
simulink model using (Simulation Interface Toolkit). Then I loaded the dll
file generated by the real-time workshop and deployed the final code into
the PXI Real-time machine. Everything is working just fine except that
when I probe the output of fuzzy logic control block, it always spits out
constant values. However, the output of the fuzzy logic block is always
constant when it is supposed to be changing as I change the inputs to the
block.
Thank you so much!

Hi Serdar,
Have you tried running your model in LabVIEW on your host computer? Try simulating the hardware with controls and indicators and see if it is running correctly without the hardware. Also does your model work correctly before using SIT to connect to it. LabVIEW and SIT only reference the model you created.

Fuzzy system from simulink to labview

Hey all, hope you are well.
I have a developed fuzzy system in simulink, how would I go about transfering this over to labview? If anyone has any help or developed a model that can do this. Any advice is well recieved.
regards
Alim Guy

Hi Alim,
This can be achieved using the Simulation Interface Toolkit, which can be purchased from this URL, which allows you to directly interact with models developed in Simulink. This toolkit will import the developed files into LabVIEW. In terms of researching Fuzzy Systems created within LabVIEW, if you have the Fuzzy Logic Toolkit, you can go to the NI Example Finder (LabVIEW > Help > Find Examples...) and search for the keyword 'Fuzzy' you can view Fuzzy Systems developed purely in LabVIEW. You can learn in depth about Fuzzy Logic Toolkit here to see if these tools suit your specific requirements.
In terms of the ease of implementation, it really depends on what you're after. It's not so much what process is easiest, but what you are suits your current process of development. If you're used to developing systems in Simulink and it's the standard at your workplace, then it's probably more suitable to implement your Fuzzy System through the Simulation Interface Toolkit; there are some extra steps required when importing the data in terms of referencing the variables appropriately in LabVIEW but it's not a lot of extra work. If you're interested in developing and implementing your systems entirely from the LabVIEW environment, it will be worth using the Fuzzy Logic Toolkit.

Reading controller data into LabVIEW through serial connections to controllers?

I'd like to read data from environmental chamber controllers (System Plus) into LabVIEW through RS232 connections. Has anyone done something similar?
I see interfacing with the serial controllers as the biggest obstacle and although not directly related to LabVIEW programming, I'm hoping someone here can give me some advice or resources on how best to do so now days.
My first thought is to write a program with VB or C++ to act as a terminal and write the data to a text file for LabVIEW to poll. Aside from using Telix decades ago to work with BBSes, my only other serial experience consists of interfacing with a Kiethly multimeter using a C++ program.
I would rather not use multiple PCs but I have never worked with more than one serial port on a computer before in the past. Perhaps LabVIEW itself already provides for multiple serial card communications (wouldn't that be perfect)?
Any info would be great.
Regards,
Dave

Thanks Dennis.
I spoke with Envirotronics and they do not provide the driver for the System Plus controller any longer since there were issues with changing hardware and software. Their IT department may be able to put something together for me.
Using USB->RS232 connections would be nice given the abundant number of USB ports available on modern PCs.
Without a driver I see parsing the serial text as a challenge in LabVIEW. I know how to approach this with a traditional programming language but are there any examples around here of how this is done with LV (most recent version is fine)?

Without NI DAQ device- how to get data from MSP into labVIEW and process it

Hi,
I do not have an NI DAQ device. I have an MSP430 and my sensor is an ADXL335 Accelerometer. How do I get data from my MSP into labVIEW and process it?
Just looking for a nudge in the right direction. I'm having a hard time finding resources on labVIEW that don't involve NI specific DAQs.
Thanks in advance,
Aziz

There are many ways to get data into LabVIEW that do not involve NI-DAQ devices.
I think your easiest option would be to stream it via serial port if the data rate isn't too fast.

How to import timestamps from excel into labview

hello everyone, how to import timestamps from a column in excel into labview?
I am bugged with this problem for long now... can anyone help please?
Now on LabVIEW 10.0 on Win7

LV and Excel use a different reference time (LV was 1.1.1904?). You need to convert between both references. I don't remember the details how I did it and I'm away from my code base.

Sending arrays from Excel into Labview

I want to send an array from Excel VBA into a LabView VI.
The Excel example shows how to send individual numbers and return an array into Excel but not send an array.
Everything tried sends blank arrays into LabView, which can then be modified in LabView and returned to Excel.
A VBA code snippit that does not work is:
Sub LoadData()
' LoadData Macro
' Keyboard Shortcut: Ctrl+l
' This is an example to demonstrate LabVIEW's Active-X server capabilities.
' Executing this macro loads a LabVIEW supplied example VI "Frequency Response.vi",
' runs it and plots the result on an Excel Chart.
Dim lvapp As LabVIEW.Application
Dim vi As LabVIEW.VirtualInstrument
Dim paramNames(0)
Dim paramVals As Variant
Set lvapp = CreateObject("LabVIEW.Application")
viPath = lvapp.ApplicationDirectory + "\examples\apps\freqresp.llb\DAK Frequency Response.vi"
Set vi = lvapp.GetVIReference(viPath) 'Load the vi into memory
vi.FPWinOpen = True 'Open front panel
paramNames(0) = "Foo"
paramVals = Sheet1.Range("j1:j1000").Value
Call vi.Call(paramNames, paramVals)
This code generates an error - expecting 1D array or variants.
However, if I supply the correct array, then LabView thinks it is empty
'foo' is a cluster
'Array' is a double array
Neither work to receive the data

Thanks for the reply but that approach will be difficult. The problem to solve is relatively simple IF LabView could read arrays (it writes arrays easily). Here is the problem:
I want to convolute two large arrays. I have written VBA programs to do this but they take too long - over 30 sec whereas the LabView version take <1 sec IF I could get the data into LabView.
The convolute is part of an optimization program that goes though many loops so that it takes hours to run efficiently AND if I manually change cells in the spreadsheet, then it takes 30sec to come back as VBA does not respect clean cells (for some reason).
I was trying to write a function in VBA to do this calculation via LabView rather than VBA. One way to do this is to write a text file in VBA and read in LabView, then pass the results back or maybe the clipboard as a buffer. That is faster but clumsy. You could also have LabView look for dirty cells and then do the calculation as the server rather than the client. Again, time consuming and cumbersome. I have written pure LabView code to do the curve fitting but prefer to use Excel as that is easier to incorporate and work with the data. You can do convolute using FFTs but Excel does not do that correctly - they CANNOT make their FFTs into a function (VBA functions cannot modify cells in the spreadsheet but only return variables. FFT modifies cells so cannot be called from a function, only a macro, which then needs to be updated manually). Again, I can kluge VBA (real kluge this time) to make FFTs work as a function BUT prefer the LabView solution, if possible, as I am not sure the FFT will actually save time.
I am not sure if the problem is LabView's fault or Excel's (2013) fault that the variables are not set-up properly. LabView claims to be able to do this. Again, you can pass single variables into LabView and read back arrays but try as I might, I cannot get arrays into LabView.
Any help in sending arrays (maybe Labview expects a variant variable and needs to convert it somehow) would be appreciated. Variants are suppose to be able to be converted automatically but maybe there is a bug in LabView (2010) that does not handle input variant arrays correctly (I have tried making them clusters, double arrays, ect). LabView thinks that all the arrays sent by VBA are empty. If LabView modifies the same array, VBA sees that modification so that the addresses appear to be sent correctly i.e. the array "handle" is being sent to LabView or else it could not fill the array to send back to VBA.
If ever this is solved, I will put on-line the solution for others as again marrying both programs will have advantages. Others may find this interesting is marry LabView with Excel so that LabView does some of the heavy calculations that Excel has kluged.

Help with reading information coming from a software into LabVIEW through Serial port

Hi,
I am new to LabVIEW and also an amateur in using RS232 for communication. I have this software that has these icons like speed increase/decrease, elevation up/down, start/stop. Now, when I click these buttons on the software, they perform the appropriate functions. For example, if I press start button, the signal must go through a serial COM port into LabVIEW to start the machine. How do I do that? How do I find what format the code word is when I press a button on the software? And how to decode the information to read whether the button pushed is start etc...? Any help would be appreciated.
V
I may not be perfect, but I'm all I got!

That information would be in the programming manual for the device you're controlling. Unless you have a device that has no documentation or you cannot get the documentation that's the first place you should look. If you cannot get the documentation at all then you've got some reverse-engineering to do. To do this you will either need a serial port sniffer (a hardware device), or you can try to use a software-based port capturing program. On Windows PortMon is the most prevalent. This will show you how the port was configured (baud rate, stop bits, etc). Warning: the information is technical.
As far as how to get it running in LabVIEW, you should take a look at the serial port communication examples that ship with LabVIEW. The most problems occur in figuring out how to (a) terminate a write command, and (b) determining when to stop reading. For (a) this is typically done by appending a carriage return or linefeed to the command. This is device dependent. For (b) this is usually done by the byte stream ending with a character like a linefeed. Again, this is device-dependent.
You may also want to peruse this KB article: Serial Instrument Control Tutorial. There are also lots of tutorial on the internet for basic tutorials on serial port communication.

No output from Simulink to LabVIEW with Simulation Interface Toolkit (0/1)

I'm able to send data from labview to simulink, but the labview
display doesn't show any output from the simulink model. I've attached
two very simple labview and simulink files which gives me this
problem. I have the same problem when trying to implement the sinewave
example in the manual for the toolkit as well.
I'm using LabVIEW 7.1 Pro, Matlab 6.5 and Simulink 5.0 on WinXP pro.

The Simulation Interface Toolkit 2.0.1 or earlier does not work with LabVIEW 7.1. There is a patch available (or available soon) from NI support that corrects this problem. THe patch is Simulation Interface Toolkit 2.0.2.

How to Map XML Summary comments/tags from OpenScript into OTM through Java

Matlab, simulink et labview

Bonjour à tous,
Je me suis renseigné sur le sujet, et j'aimerai savoir si j'ai bien compris.
On peut incorporer du code matlab dans labview , via la boite script "matlab" du diagramme, pour utiliser simulink avec labview, il faut creer une dll à partir du code généré sous simulink.
Est ce que j'ai bon, ou peut on incorporer aussi du code sous simulink dans Labview, via une boite spéciale.
Merci pour vos réponses

Bonjour,
Merci d’être venu sur le forum de National Instruments.
A priori vous avez bien compris comment intégrer du code Mathlab dans LabVIEW. Pour ce qui est de Simulink il faut effectivement appeler un DLL créé sous Simulink. Ce lien vous permettra de savoir comment faire.

Merging iWeb 06 site into iWeb 08 site

Hi,
I've looked around at other posts regarding this subject but don't really understand what's going on.
I have an old site built in iWeb 06 that I want to use in iWeb 08. I have multiple copies of the Domain.
I have a new site built in iWeb 08. The domain file is in users/app support/iWeb folder. It is the only file in that folder.
Is it possible to be able to launch 08 and show both my sites in the sites pane instead of having 2 domain files for each site or should I just keep 2 domain files in the iWeb folder? I'm kind of nervous about that because I have noticed if I'm not careful, I will overwrite a Domain file and lose what ever I had on the old one. I thought about launching 08, starting a "new site" (in addition to the one already built) and somehow copying and pasting the old site from 06 into a "new site" section of 08 but I can't figure out how to do that.
Again, I do have multiple copies of each websites domain file.
Thank you for the help. I think others have had this problem as well. I'll see what else I can come up with.
Thanks, LowBb

I found this posted by Roddy,
