Model Interface Toolkit Evaluation

I have a need to integrate a Matlab/Simulink model into LabVIEW. Luckily I saw that NI has a few options. Recently NI had updated their toolkit and call it the Model Interface Toolkit and include it with Veristand 2013. So I downloaded Veristand and installed the toolkit. I then went to the Example Finder and opened the MIT User-Interface with F-14 Model to see it work.
The problem is the VI is broken, and reports "This VI or item belongs to a library that is in evaluation mode." Well yeah so what I want to evaluate it to make sure it works with my stuff before buying it, isn't that the purpose of an evaluation? This seems like a bug that VIs won't run in evaluation mode. That would be like evaluating LabVIEW but not have a run button. What good is the evaluation?
Can someone at NI help me to get a working evaluation of the Model Interface Toolkit before I decide if the product is right for our application? Thanks.

If 10 out of 10 experts in any field say something is bad, you should probably take their opinion seriously.

I must be missing something here. So for all other LabVIEW toolkits I've ever used, you download it and install it. During the install on the newer ones they will say, do you want to enter your serial number or just run in evaluation for a little while. I selected evaluation which gave me 7 day with the option to extend. When I launch LabVIEW it shows that the Module Interface Toolkit is installed and in Evaluation (2 days remaining at the moment). I choose to Launch LabVIEW anyway. Every example in the Example Finder that uses the Load Model function is broken. This is all examples other then the "Importing Model and Setting Light.vi" example.
I do not have the Control Design and Simulation Toolkit installed. Is it requried? I don't need to make simulations I need to control already made models which is what the Model Interface Toolkit looks like it does. Thanks.

Does the Model Interface Toolkit support the new Linux based cRIO-9068?

Hello, I have a cRIO-9068 and am needing to integrate a Simulink model into my controller. Does the Model Interface Toolkit support the new Linux based cRIO-9068? For that matter, does Veristand? This page implies that it does not:

Model interface toolkit (MIT) code generation failes in simulink

Hello,
I'm running into an odd Simulink Coder failure and I can't tell if this is due to an NI/MIT but or a general Simulink Coder issue.
System:
Windows 7
Matlab/Simulink R2013b w/ Simulink Coder
MIT 2013 SP1
System target file = "NIVeriStand_VxWorks.tlc"
Not that we even get to this point but... my "WindRiver GNU Toolchain Setup Path" is properly configured to: c:\gccdist\supplemental\setup-gcc.bat
The attached image shows the error I'm getting:
"Error: Invalid character in: 'SMA_model/SMA Driven Arm/wire/Heat Transfer Model/ ', exiting code generation. The name cannot end with / character".
In the image you can see that the "Heat Transfer Model" subsystem in fact does not have a "/" in the name.
Has anyone else ever run into this code generation problem before? If so, any suggestions on how to get around it?
Thanks.
Solved!

That error is actually being reported by Simulink® before the build process begins. I'm guessing you would see it regardless of the TLC file you choose. Interestingly, in my tests here Simulink® doesn't allow me to leave a subsystem with a "/" at the end of the name. It automatically changes the name back to what it was before I tried to add the "/." That same error you see in the compilation window is displayed in the command line output when I attempt it. It looks like I'm running a different version than you though.
The screen shot doesn't really confirm the subsystem block name itself, at least the hierarchy at the top of the window appears to have parsed out all backlashes. Could you provide a screenshot of the heat transfer model subsystem block?

How do i pass a daqmx task from labview to matlab using the math interface toolkit?

I want to use DAQMX functions from Matlab using the Math Interface Toolkit (MIT). How can I have a labview function output (return) the DAQMX task to matlab via the MIT?
I want to do this so I can start a DAQMX task in Labview from a matlab function and return control to matlab without losing the task.

Hi Mark,
(I already posted this answer in your other thread, but let's keep THIS thread alive - it makes more sense here in the LabVIEW forum than in Instrument Control forum.)
Since the DAQmx Task is not a native data type that can be passed directly to MATLAB from LAbVIEW, try flattening the DAQmx Task to a string before passing to MATLAB. However, I doubt that you can access the task from within MATLAB, but feel free to give it a try.
Good luck!

Required SW for the Simulation Interface Toolkit

Hello,
I would like to add a LabVIEW front panel to my Matlab/Simulink model. According to the data sheet, the following software is required for the SIT:
System Requirements
The LabVIEW Simulation Interface Toolkit requires that you have a
proper license for the following products:
• MATLAB® version 6.0 or later
• Simulink version 4.0 or later
• Real-Time Workshop® version 4.0 or later
• Microsoft Visual C++ version 6.0 and
• LabVIEW version 7.0 or later
To simply create a LV front panel for my model, do I still need to have LabVIEW installed? If so, which versions would be compatible?
I currently have the student version of Matlab 6.0 and Simulink 4.0. Will the SIT work with the student version?
If I only want to create a LV front panel, do I still need to have the RT Workshop or Visual C++ installed?
Thank You,
Mike

Greetings!
Yes, you are required to get the sw as mentioned.
To simply create a LV front panel for my model, do I still need to have LabVIEW installed? If so, which versions would be compatible?
Yes, to create a LabVIEW user interface / front panel, LabVIEW is required. LabVIEW 8.2 is the latest version.
The Simulation Interface Toolkit (SIT) 3.0.2 updates SIT 3.0.1 to support LabVIEW 8.2, the LabVIEW 8.2 Real-Time Module, and the LabVIEW 8.2 FPGA Module. You also can use SIT 3.0.2 with LabVIEW 7.1.x or with LabVIEW 8.0.x. However, you cannot install SIT 3.0.2 for more than one version of LabVIEW on the same computer.
2. I currently have the student version of Matlab 6.0 and Simulink 4.0. Will the SIT work with the student version?
The MathWorks, Inc. MATLAB® / Simulink® application software R2006a.
The MathWorks, Inc. Real-Time Workshop® R2006a.
Support for The MathWorks, Inc. MATLAB® / Simulink® application software release 13.x or 14.0, 14.1, 14.2, 14.3
If you install SIT 3.0.2 for LabVIEW 7.1, you can use Microsoft Visual C++ 6.0 to convert models to model DLLs. If you install SIT 3.0.2 for LabVIEW 7.1.1, 8.0, 8.0.1, or 8.2, you can use either Visual C++ 6.0 or Visual C++ .NET 2003.
If you installed more than one version of The MathWorks, Inc. MATLAB® / Simulink® application software, SIT installs support only for the latest version on the computer.
You want to make sure the Matlab release is one amongst the above.
3. If I only want to create a LV front panel, do I still need to have the RT Workshop or Visual C++ installed
RT Workshop comes with SIT. You will have to get Visual C++ and use that compiler.
Thanks and hope this helps
Best regards

Simulation interface toolkit tutorial

I'm trying to perform the tutorial titled "Converting a Simulink Model into a Model DLL", found on p.22 the Simulation Interface Toolkit manual (http://www.ni.com/pdf/manuals/370420b.pdf).
It starts off by building a new Simulink model of a sine wave (p.9). On step 7 of that process, it mentions a "NISink" block from the "NI Toolkit Sinks" library in Labview. I do not see this library, and I got zero hits when I searched the libraries for "NISink". I do have a library callled "NI SIT Blocks" but it does not have a "NISink" block, only "SignalProbe", "SIT Out1", and "SIT In1".
I am using SIT V5.0 with Simulink V7.2(R2008b), but the tutorial appears to be a bit older, perhaps from SIT V2. I assume that "SIT Out1" has replaced "NISink" but, as a novice, assumptions bother me. Is there a more up-to-date users guide available? I found the "SIT 2009 Help" file online (http://zone.ni.com/reference/en-XX/help/371504E-01/) but the how-to's there do not contain any tutorials.

I found a help example that was installed on my system with Labview, obviously a little more up to date. It’s also found online here:
http://zone.ni.com/reference/en-XX/help/371504E-01/TOC5.htm
I ran through the help example for the SIT how-to "configuring a simulation" and it worked as expected. When I then proceeded to the "configuring a simulation on a real-time target", I found that tasks 1 and 2 were already complete and verified working from the first how-to. During task three, however, step 7 fails at compile time (see attached file matlab_output.txt)
It looks to me like it is mssing a header file from the Simulink Real Time Workshop (called rtwtypes.h). It contains declarations for some sized and unsized generic data types, including uint_T. However, that file is available in the regular RTW library directory. Not sure why I can use the SIT server in Simulink to control the s-function with LabView, but I can't build a stand alone DLL for a real time system.

Simulation Interface Toolkit

Hello,
I'm using the Simulation Interface Toolkit 3.0 because I want to control a Simulink model in LabVIEW 7.1. For instance, I want to generate a sine wave using a constant block. In this manner I can provide to my Simulink model every kind of signal without changes in it.
To perform this task Simulink needs an input value at each integration step.
I would to know if this task is achievable and if someone could tell me something about the communication between LabVIEW and Simulink.
Thank you for your help!:smileywink:

Hi Alessio,
Maybe you have the solution to my problem:
I have a Simulink model that works with a LabVIEW VI using the Simulation Interface Toolkit and the SIT server.
In order to use this model and this VI without Simulink, I created a dll (nidll) of my Simulink model like shown in the following manual:
http://www.ni.com/pdf/manuals/370420b.pdf
By doing so, LabVIEW automatically created 6 VIs that should work with my model DLL.
My questions are:
- Can I use the VI that I previously made for my Simulink model with the model dll ?
- If yes, How ?
- If no, How can I use my model dll and these new VIs?
Thanks in advance.

Simulation Interface Toolkit 4.0 cannot map to indicator

I have LabVIEW 8.5, SIT 4.0 and Matlab R2007b which uses Simulink 7.0. NI has a manual and example for using the Simulation Interface Toolkit at http://digital.ni.com/manuals.nsf/websearch/679117802743CC128625732B00697485 I can map control signals just fine between LV and Simulink but when I try to connect an indicator such as a Waveform Graph or numeric indicator to Port 1 of a Simulink object like a Sum block or Sine Wave (as the example shows) it always says that the mapping is invalid and greys out the box. It seems like there is a bug here because this should just work. Port 1 of a Sum or Sine Wave should be its output as a scalar. Anyone that uses the SIT have any ideas?
I've attached the help file with example that I followed.

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:

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.

Hi Z
Please make sure that you have version 1.0.2 of the math interface tool kit as version 1 is not fully compatible with LabVIEW 8 you can check what version you have if you got to start>>control panel>> Add Remove programs >>National Instruments>>change look for Math Interface Toolkit XX.
Here is a link to check what version of the tool kit you need for different versions of LabVIEW

Math interface toolkit install

Hi,
Please is there any chance to download somewhere a trial of the math interface toolkit?
I want to use my VIs on matlab as a GUI, and I guess this is the tool to make it works...
Thanks, Pierre

I installed evaluation version of Math interface toolkit to convert VI into Mex functions.
but the toolkit only allows me to make LNX functions, there is not Mex function tab.
I installed the evaluation version...and in the tools menu it says "math interface toolkit for xmath" which I think is not the toolkit i'm looking for.
I downloaded it from the link :
http://zone.ni.com/devzone/cda/tut/p/id/2716
I tried both links on the above page i.e NI LabVIEW Math Interface Toolkit (MIT) and NI LabVIEW Math Interface Toolkit. but both install it for xmath and only make LNX function.
where I can get the right toolkit?

Posting the same question, multiple times is just impolite and does not get it answered quicker. You posted this thread 10 minutes after you posted the first question.

Math Interface Toolkit in Matlab: Can I interact with a VI as a parallel process

I'm curious if it's possible to create a Matlab MEX file using the LabVIEW Math Interface Toolkit (MIT) that can be called in matlab and accessed while running?
I'd like it to effectively work just like any other object in matlab. I'd like to be able to query the object while it's running, dump values out of a buffer, and even hook events if possible.
As it currently stands, the VI to MEX setup seems to just allow me to call a VI, run it, and then drop out. I want to be able to continuously acquire and access the data as it's coming in and interact with it from matlab (i.e. fully integrate the VI into my matlab code as a separate object).
Is this possible in some form or am I stuck with dedicating the matlab interface to the VI whenever I want to call it?
Thanks

Hi GusLott,
You are correct that when you call a VI the command line will not continue until the output is obtained. This makes sense since in LabVIEW that is how a VI operates (a subVI does not ouput until all outputs are obtained). I believe this is also how commands in MATLAB work as well (correct me if I am wrong). On the otherhand this is not a disadvantage in labVIEW since you can run VIs in parallel. If you can create some way to run parallel threads in MATLAB then you will be able to do two (or more) MEX calls at once.
As far as object oriented programming goes, there is a labVIEW OOP, but I do not think it has been tested in conjuction with the Math Interface Toolkit.
