Schnittstellen zwichen Matlab/Simulink und Labview

Hallo Leute,
ich habe ein Diplomthema wo ich muss ein Fpga I/O (muss nicht die ganze I/O sein) mit ein block in Simulink(Simulink Model) aufrufen.
im moment kann ich die Programmierung des Fpga auf ni pxi 7813R unter labview machen und dann würde mir ein file konfiguriet.
Um ein Simulink model mit Labview zu verbinden braucht man SIT .
Jetzt kommt die Frage :die I/O des Model kann ich nur unter labview definieren, nun musse ich jetzt in meiner Diplomaufgabe in Matlab/Simulink in einer Blockset definieren .
Weiss jemand irgendein Information darüber, ich weiss noch nicht wie kann ich das realisieren. bitte sagen sie mir jede Information die mir helfen kann . ich wäre sehr dankbar

Hi,
ich benötige leider dringend und kurzfristig Hilfe.
Ich hab eine 10-15 Seitige Hausarbeit geschrieben bzw. bin noch dabei, es geht um die Kopplung von Simulink mit LabVIEW zu schreiben.
Die Note der Hausarbeit, wird meine Zeugnisnote für dieses Fach sein.
Daher suche ich jemanden der sich das durchlesen kann und von der Materie versteht.
Natürlich gegen Zahlung
Bitte um schnelle Rückmeldung.
Lieben Gruß,

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.

ABS from MATLAB (simulink) to Labview (.vi file)

Hello
My Antiskid Control System project requires me to plot the graphs of wheel speed and vehicle speed. The original model is from Matlab simulink file-absbrake(this is an example of control)
I tried to convert the whole system into labview representation. I donot want to use SIT or RT or any other Labview tools. I wanted to convert from Simulink model into Labview element-by-element. Can anyone help me...plss
my due date for submission is 15march...so please help me

abs.vi is the file that i attempted to 'convert' from matlab into labview

FPGA Interface between Simulink/Matlab und Labview

Hello People,
I has a diploma topic, where I must call a Fpga I/O (AI/O or DI/O) from a block in Simulink(Simulink Model) . I can make the programming of the Fpga on ni pxi 7813R under labview . Around a Simulink model with Labview to connect one needs SIT.
Now the question:I can define the I/O of the Simulink Model under labview , now I must the I/O in Matlab/Simulink in block set define . White someone any information about it, I white not yet as I know that realize please to say her me each information me to help can.
Thanks very much

Hello FourtwonaFirst thanks for your answer and your interest, I try to explain what i want to realize. I have a Model in Simulink, I can this Model connect in LabVIEW with simulation interface toolkit, and with SIT Connection manager the hardware I/O as Model I/O configure.
I would like to make the I/O interfaces of a FPGA 7813R PXI system from Simulink accessible. Similarly as with dSPACE RTI block, I can access the I/O from Simulink means over S Function Block. for example Analog Input.
Also I want to define the I/O of the Model as FPGA I/O in Simulink and then can I build the ModelDLL in Matlab and in SIT download. finally run the Model-simulation on RT Target.
I think, we need access to the visa server. I am on the search for this concept.
Perhaps you or someone can support me.

How can I put C files gave me from Matlab Simulink Real Time Workshop in a CIN?

I'm doing a turbine simulation, and I've already done it in Matlab Simulink Real Time Workshop. It gave me files .c, and I want to use them to run the same simulation on a PCI 7030/6040 using LabView RT 5.1. I'm using the CINs. My problem is that I'm able to have .lsb files, but them don't work....I mean I have as output the same result 0(zero). What can I do for solving my problem?
Thanks in advance!!

Somehow, this question was posted twice on the same day. See the other posting of this same question for the answer.

Simulation Interface Toolkit - How to toggle a manual switch in simulink from LabVIEW?

I have a manual switch in my simulink diagram that I want to use to switch between to values from my LabVIEW interface. I have tried to connect a toggle switch at LabVIEW`s VI with different parameters in the simulink model(I can choose betweenhow Port Labels, sw, and action), but none of them seem to work properly.
The manual switch in Simulink gets to inputs, one output. There is also an Environment Cotroller that output the simulation(SIM) or Real-Time Workshop(RTW) port depending on the current environment.
At this time I am doing simulations and are not using Real-Time Workshop.
I want to thank you for your help in advance.

Hi
Kotsya,
Thank you for posting to the National Instruments Discussion
Forums.
If you are not using the Math Interface Toolkit, you may be
interested in using the MATLAB® Script Node. This allows
you to call MATLAB® commands using ActiveX and I you
can call your Simulink model from MATLAB® that way.
Here are some resources on how you can do this:

Simulink and Labview

Hi all,
could I use the SimMechanics(Simulink) to create a mechanical model and after that create a DLL with the SIT(Simulation Interface Toolkit) to use it in Labview?
Thank you.
Ziman

Hello!
Yes, you can have SimMechanics and build a DLL and then use it in LabVIEW using the Simulation Interface Toolkit.
However there are a few things to consider since it seems like it works quite differently compared to ordinary Matlab/Simulink
Quote:
“SimMechanics model differs significantly from other Simulink models in how it represents a machine. An ordinary Simulink model represents the mathematics of a machine's motion, i.e., the algebraic and differential equations that predict the machine's future state from its present state. The mathematical model enables Simulink to simulate the machine. By contrast, a SimMechanics model represents the structure of a machine, the geometric and kinematics’ relationships of its component bodies. SimMechanics converts this structural representation to an internal, equivalent mathematical model. This saves you from having to develop the mathematical model yourself."
I am not sure whether the mathematical models are present for the user for optimizations purposes.

Measure signals from Matlab Simulink Model

Hi,
I modeled a six bus power system network on Matlab/Simulink and I would like to measure the voltage and current signals using a DAQ card. The DAQ card im having is a
NI PCI-6132 S Series Multifunction DAQ. How do I go about acquiring this signals?
Regards,
Louwrence

Hey Louwrence,
Are you going to be using the 6132 card with LabVIEW to acquire the signals? If so, you should look in the NI Example Finder that is installed with LabVIEW. Go to Help>> Example Finder. Then go to Hardware Input and Output>> DAQmx>> Analog Measurement and choose the example you would like to look at.
If you are trying to use the card through MATLAB, you will need the DAQ Toolbox. You can check for official compatibility here. I do not know what is installed with this toolbox as it is not National Instruments. There may be some examples in there however.
Hope this helps.

How to use matlab function with labview?

Hello,
I just want to use some matlab functions like floor(),ones()... in my labview code, who can tell me how to do it?
I want to only install MCR in my PC, so MATLAB script node can not work because it need matlab installed.
Thanks
Solved!
Go to Solution.

floor() exists on the standard labview pallet already and the ones() function would be fairly simple to reproduce. If you only need a few basic functions repost asking for direction on recreating those specific methods. However, you're right - there is not a direct way to use compiled matlab code in labview without full matlab and the math script nodes. If you're really desparate to reuse some some exisiting IP there are C++ alternatives that implement many of the same methods and syntax as matlab (http://arma.sourceforge.net/faq.html). I'm fairly sure there are other tools that attempt to translate matlab code into pure c functions, both of which can be called via a DLL from within labview: https://decibel.ni.com/content/docs/DOC-9076
Alternatively, here is an all NI linear algebra solution: http://sine.ni.com/nips/cds/view/p/lang/en/nid/210525

Same code gives different results in Matlab Script in Labview and Matlab

I am implemeting a Matlab code into a LabVIEW application using Matlab script. When I import the exactly same code to the Matlab Script in LabVIEW it gives a different result than it is in Matlab. This code is a simulation code including first kind bessel functions. Using LabVIEW 7.1 and Matlab R14 service pack 3.

Labview 8.5
Matlab R2009b
Attached are the graphs produced by matlab script in labview and in matlab.
The minimum of graph produced by matlab code is below 1 and that in labview is above 1.
Thanks a lot for your reply.
Sorry, I haven't quantified the "sometimes" yet.

How to use a Matlab Program within Labview

Hi
I saw in this forum that many users are using some matlab program
executed in Labview program. I have actually Labview 7.1 and would like
to use some of my matlab program in Labview. Is there an easy way to do
it ?
Thanks
Thomas

The MATLAB Script function is kinda buried in the function palette, and
can be found under Functions >> Analyze >> Mathematics
>> Formula. Unfortunately this feature is not available in
the LabVIEW Base package. Hope this helps!

Using Matlab code in LabVIEW

Hi,
I have never used LabVIEW and I am wondering if there is a way to run Matlab code in LabVIEW. If so, how would I do it and are there any special instructions or tips I should know about?

What is your LabVIEW version?
Do you have matlab installed on your computer?
In older LabVIEW versions, you can only use the matlab script node, which requires that you have a copy of matlab installed.
In newer versions, you have two more alternatives that don't require the purchase of Matlab:
Use a mathscript node.
Use a scilab script node.
Information on mathscript: http://zone.ni.com/devzone/cda/tut/p/id/3502
Information on scilab: http://zone.ni.com/devzone/cda/epd/p/id/657
