• Reproduction of example of Simulation Interface Toolkit

  Hello everyone,

  trying to replicate the example provided in the Simulation Interface Toolkit - how-to , I am facing an error with LabVIEW 2009.

  I have created a host VI working with the file .mdl Simulink on localhost as Simulation environment that runs smoothly.

  And I can't properly compile the file desired .dll (sinewave.dll) with Simulink and nidll.tlc.

  But if I want to use a cRio-9024 as time real target FPGA-interface I get the following error when I start the host-VI:

  Missing file of Simulation Model

  The sinewave.out simulation file could not lie in the projected paths. Please FTP the file manually to your system in real time.

  The following planned paths do not contain the simulation model:
  C:\ [...] \sinewave_nidll_vxworks_rtw\sinewave.out
  C:\ [...] \sinewave_nidll_rtw\sinewave.out

  Why should I produce a file called sinewave.out? I don't think that I really need.

  Can someone tell me please how to use the sinewave.dll properly to make it work on my cRio?

  (I don't want to use e/s material and yet, just run the file .dll on the cRio.)

  The best help for would be a description step by step from a VI of work using sinewave.mdl inside LabVIEW with ready to use sinewave.dll.

  I need to examine any document in order to complete this example?

  Thanks for your effort!

• Changes in the driver vi using the Simulation Interface Toolkit (SIT) for PXI get do not appear.

  Hello

  I use Simulation Interface Toolkit to target a controller built in Simulink on a PXI target. I used the SIT connection manager to generate the driver screws I had to make some changes in the screw driver specifically Read.vi IO. I made the changes and the entire application runs without error. But the changes are not getting in the functioning of the application, essentially when I load the thing on PXI and run it, it contains exactly as it was before behaiving I made these changes. Some how the changes I make to the Read.vi of e/s are not begin day somewhere in the top vi driver.

  Could someone help me with this please.

  Eliane.

  Hi Justin_P,

  Thank you very much for the reply. Solved the problem. What you're saying, that's certainly true, but I do not use the project.

  The problem was that whenever it makes a change one driver that saw VI top-level driver must be opened and saved again. This opening and registration links the pilot with new changed correctly VI and then everything works fine.

  Thanks again.

  Eliane.

• simulation interface toolkit?

  Hi all..

  I have installed LV2014 & model Interface toolkit... but I can't find the function to SIT in the tool Menu,

  Where can I install SIT?

  Thank you!!!

  Simulation Interface Toolkit was the Toolbox that you used to call the models, but since LabVIEW 2013, it has been replaced by the model Interface Toolkit.

• Academic version Simulation Interface Toolkit

  Hi, I am a student Brazilian and I use the Labview in my monograph.

  I need communication between Labview and Simulink. I have in my computer of 2012 Labview and SIT AcademicVersion installed that came to the DVD of the academic version of Labview 2012. I also have the Matlab R2009b X 32.

  It is possible to establish communication using this version of the software.

  UMA outra alternativa e voce converter o modelo mdl você possui para LabVIEW using a Simulation Model Converter dialog box

  http://zone.NI.com/reference/en-XX/help/371894G-01/LVSIM/sim_simtrans/

  E to você puder use o LabVIEW 2013 you can use model o Interface Toolkit (MIT), than substituiu o SIT e possui uma abordagem but intuitiva.

• Problems of Timing Simulation Interface Toolkit Custom IO

  I implement a model of .dll Simulink (execution with a stage of integration of 50ms) with SIT in real time and need to communicate via UDP to another device sockets two-way such that all packets are sent from one to the other in-sync and respecting the time constraints of my loop of base fare.

  To repeat: in the designated for playback in the basic loop vi rate that is generated with Connection Manager, I block structure UDP listening on different ports for my other camera packages (non - OR) and to introduce data in the .dll file, and similarly the structure designated for writing I will send packets to this device. Think that the control loop.

  I have not yet started to implement this because I realize that when these two asynchronous devices are listening/sending packages will not be at the same time I don't have a synchronization mechanism. I do not think that they must stay synchronized each interval of 50ms, but problems with drift, I should address later.

  For a first cut, where can I implement a block that will sit and wait indefinitely until my other device not - NOR sends a packet of synchronization of a certain type then 'kick-off' iterations of 50ms of the original model with a known relative chronology.

  Or is there a better way to handle this? I think this would be a common problem for simulations involving control loops. How is it usually implemented in OR in real time with SIT?

  Hi gdubb85,

  You should be able to do this by adding a while loop outside your VI driver with a wait until the next ms Multiple set to 50 m in this loop, you can listen to with a reading of the UDP packets and send the data you receive to help a functional global to your model.

  Kind regards

• simulation interface toolit

  Hello

  I want to connect the signal generator of Labview for the DLL generated from the simulink model.

  My simulink model has 2 ports of entry 1. Sinus and 2. Cosine.

  How can I connect these ports of entry for the labiew signal generator.

  Is this possible? because I'm not able to see all the Ports of entry during the SIT connection manager mapping.

  I am not able to connect directly to the dll as model...

  Should what type of entry ports I use in the Simulink model, so that Labview signals can be connected to the simulink model. ?

  Thank you

  Mandar Malji.

  Hello Mandar,

  the inputs and outputs of your model can be updated in the VI driver using an array of size of the data, as described in the SIT help (see the link in one of the previous posts):

  "Create a custom driver VI, to correctly index in the table to the size of the data, which is where the Simulation Interface Toolkit places the data of i/o channels. see the modelname _portsReadme.txt file, located in the build model DLL folder, for the list of the order and the widths of all the entries of the template and outputs." The index number of the paintings is the sum of the width of all of the above. For example, the index number of the element 3 is equal to the width of the element 2, more the width of the element 1. »

  If you update the elements of this array of the size of the data with your own code, you can change the values of input for your model, for example. It is important that information how the data is organized in this table are described in the file _portsReadme.txt modelname. This file is automatically generated by the Matlab/Simulink real-time Workshop when the dll model is created from the .mdl file.

• The interface of LabVIEW and matlab

  Hello, I want to interface LabVIEW with MATLAB using the TCP/IP protocol for data transfer. Can anyone, please give me an instruction step by step how to do this? If not, can point out you where I can get them? Thank you.

  Hi Gilles,.

  TCP/IP is a generic protocol then you should easily be able to build enough interfaces TCP/IP for your LabVIEW and Matlab code and data transfer on ASCII or variants, etc., depending on what kind of data you are trying to transfer. I'm not too familiar with Matlab, but on the end of LabVIEW, there are a few examples of server and client very good TCP/IP provided with LabVIEW.

  Another option you may want to, and the reason why I answer it is that I did recently a project through which we took some legacy code MATLAB which we wanted to transpose into LabVIEW, so that we can automate then completely a test system that we use TestStand. A big part of it, we have been able to derive equivalent LabVIEW, but some functions where LabVIEW does not have an equivalent appropriate, or where it was simply more effective, simply copy us and paste Matlab code in any event in the first instance MathScript nodes (not dependant on Matlab) or Matlab script nodes (which will return if all goes well at a later date to transpose in full) LabVIEW for that is no longer dependent on a Matlab license).

  In both cases, the facility to do this was very impressive, and we were able to wrap huge amounts of code Matlab LabVIEW with very few problems. As an idea, have you considered your functionality of Matlab of packaging in this way and keeping all the customer TCP/IP and comms server in LabVIEW?

  Note: If you have not found it pick up the palette "Matlab Script.

  Good luck

• Can I change the period of 'model' of a Simulink model running with the model interface toolkit (MIT) programmatically?

  I would like to be able to programmatically change the time step, a Simulink model uses when it is called by the model Interface Toolkit LabVIEW. The time step is a template parameter or a signal of model. Is this possible to do?

  It is not possible. The timestep for the model is fixed and compiled in the model. You can do things like relaxation model subsystems based on a value entry or event within the model.

• New MacBook (12 ", towards 2015/2016) and MATLAB

  Hey everybody,

  does anyone have experience with the new MacBook (2015/2016) and MATLAB?

  I am currently using the MacBook Pro now after 6 years I want to something new, but I'm quite bad if I have to buy Air or the new one (1.3 GHz dual-core Intel Core m7, Turbo Boost up to 3.1 GHz, 8 GB memory SDRAM 1866 MHz LPDDR3, 512 GB PCIe-based embedded flash storage Intel HD Graphics 515).

  I am a student of neuroscience so I use matlab x times per week as well as spss, otherwise its all the usual stuff (office, senseless surfing the internet, average of much netflix etc.). I will still use my Pro, with a new hard drive, but carrying 2kg of Mac around campus is horrible.

  I regret the new 12 '' MacBook?

  Thank you!

  See you soon

  Magda

  I use the new Macbook and Igor Pro that is similar in the CPU usage and data processing capabilities. I also have a 15 inch MB Pro, which is a pain to lug around... you will be happy with the new Macbook and don't suffer from the "slower" processor if only using MATLAB.

  One thing to keep in mind is that there are only two hearts, then if you don't have any parallel treatment (whether through Matlab or other calculations) they will be slower. If you do not I recommend the Macbook.

• Communication between PCI6251, Labview and Matlab

  Hello

  I work with a Council of PCI6251, driven by an executable labview.

  I get measurements from several sensors (pressure, temperature, etc.) which are read by the executable of labview.

  I would like to know if it is possible to send these Matlab measurements at the same time.

  I mean: is the PCI6251 card can send data to Labview and Matlab at the same time of acquisition?

  Or I need to install a second PCI card for that?

  (Labview and Matlab are installed on the same PC now)

  Hi Nico974,

  If you want to transfer data from LabVIEW in MATLAB, you have to use ActiveX connection between 2 software or to add the node to MATLAB in you program LabVIEW (see http://digital.ni.com/public.nsf/allkb/2F8ED0F588E06BE1862565A90066E9BA?OpenDocument)

  Another solution is to use the of MathWorks Data Acquisition Toolbox, because the card PCI-6251 is supported by this Toolbox (http://www.mathworks.fr/products/daq/supportedio14005.html)

  But here you have a LV executable so if you can't change it you will not be able to use your exe and a Matlab Script at the same time, if you need another PCI card.

  Sincerely

• Myrio and Matlab script

  Hello

  I control my physical robot with labview and my rio. I also have a matlab (m.file) code that uses it the Robotics Toolbox in Matlab. I would like to add this m.file to my labview program. Can I create a matlab script in the program labview and matlab code inside and deploy code to myrio? It will work in this case?

  AFAIK, the nodes in script call script software MATLAB server to run scripts written in MATLAB language syntax. But I don't know about adding my rio to the loop.

  Thanks for the reply.

  I also later get to know that this can be done by establishing communication between Matlab and myrio wifi.

• Difference between FFT LabVIEW and Matlab FFT

  Anyone know why there is a lag in the absolute levels of the results of the function in LabVIEW and Matlab FFT?

  See the VI attached for an example of my code to LV.

  Also attached is the plot generated in Matlab, which seems to be compensated by ~ 37dB.

  This was generated by using the command "plot (10 * log10 (abs (fft (x))))", where x is the same as in the VI input array.

  Thank you very much

  Dan

  I see you are using the VI of spectrum FFT which returns a unique range of face.  To convert a transformation both sides (IE FFT) in one spectrum sided with RMS units there is a standardization of sqrt (2) / n, where N is the number of points in x (t).  You can prémultiplier your x (t) by N/sqrt (2) and get the same results as Matlab.  Or, you can use the FFT.vi so you compare transform to transform instead of spectrum to transform.
