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.

Best regards

    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.)

  • 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.

    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.

  • PowerCLI interface / tools

    Above is what I use... can we get any better tool for interface... a lightweight & handy...

    For example we use mRemoteNG to putty.exe

    PowerCLI is a number of PSSnapins and version 6 partially modules that run in PowerShell.

    You can use any PowerShell interface to use the PowerCLI cmdlets.

    The PowerCLI includes a CLI which takes care of those PSSnapins (and the modules since v6) for you.

    But you can use what PowerShell interface you want, you will need to load the PSSnapins PowerCLI and the modules since v6, yourself.

    These interfaces can be the provided PowerShell ISE or one of the commercial IDE that exist.

    Some examples: ISESteroids (an Add on ISE), More of PowerShell, PowerShell Studio...

  • 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

    While it is for 2011, I doubt that they decided to remove 64-bit compatibility as they went forward as 64-bit has become more rather than less demand.  In this document,notes LabVIEW Simulation Interface Toolkit does not support 64 bit versions of MATLAB application software."

    The extent of the compatiblitly for 32 - bit, I'd take a peek at: http://digital.ni.com/public.nsf/allkb/D174674A91E5536286257428005C2426

    The OP's question was SIT support 64 - bit version of LabVIEW and 64-bit version of the MATLAB/Simulink itself, not the operating system software.

    Document in your second link is on a completely different topic to have API for LabVIEW and MATLAB/Simulink/RTW (well, mostly Simulink & RTW). Here is the relevant link for the 32-bit compatibility: http://digital.ni.com/public.nsf/allkb/049295038FF0EE2A86257A06006B2DAD is no SIT 64-bit.

    Other underlying issues is that Pharlap does not have a 64-bit version. Finally, simulations are better performed on some RTOS (embedded PXI) for a deterministic execution rather than PC operating systems.

  • Localized user interface

    Hello

    I have some problems to reload the complete dictionary (GSD file)

    with the LabWindows/CVI 'User localized Interface' tool.

    DO NOT run a multilingual, with the good translation software.

    The final executable works perfectly, with LWL file.

    BUT if I need to correct an error of translation (I'm only a man ).

    and try to reload the previously saved dictionary (GSD file) for that.

    After leaving the tool,

    many completed translations previously disappeared (see pictures attached).

    You can save the dictionary as much time you want.

    After put again and again... the same missing translation.

    Whenever you reload, after the tool 'User Interface localized',

    some translated lack again and again in the tool.

    See the attached example.

    See with 'Fonction_EN. GDL' and 'OK (enter)' message button of the Panel "in context".

    It is correcly filled in the final file of LWL, so the executable is correctly loaded.

    But it still does not save in the GDL dictonary file.

    We had the problem, since almost LabWindows/CVI 2012 (and perhap previously).

    And especially with some IUR with many panels on the inside

    and/or using the same translations (__OK, __Cancel, etc...).

    Thanks a lot for your help.

  • Support of basic interface

    Hello world

    I received one the development of Playbooks, and I need to develop at least an app before a certain date in order to own the device.

    I was simply going to one of my IOS apps for the playbook of port and present it as my eligible application before starting to work on a game or something.

    However, I have found that the SDK is available for development for Playbook Miss INCREDIBLY.

    All I want to do is a background image, with a 'picker wheel' (this could even be approached with a view of small table), there would be a bunch of lables dot background.

    Manipulation of the selector wheel would affect the values of the help of labels.

    This app took me half a day to develop with Xcode for iPhone and iPad (which at the time in question 3 resolutions)

    I'm recreating this application on a device, with resolution of 1 (the playbook), I already have all the data and resources ready to leave when I developed it for IOS (the creation of these resources took most of the half-a-day when developing for IOS)

    Me seems to have very few options here, and when you develop with the native SDK, there are just a few examples of the C language (seriously? don't not even c ++?) I use the IDE provided and I can build the fine of the camera, but any specific syntax of c ++ causes the build fails. I am a proffesional software engineer, and I know what I'm doing with regard to the creation of the actual product. What is simply baffling to me how little effort RIM seems to have invested in the developer tools. I spent weeks trying all the options I can find including the marmelade SDK, which does not offer many of the design interface either as it is a compatibility layer and not intended to be a complete development environment, however it offers a lot more than what RIM does.

    Is could someone please tell me I'm missing something, that there is a design tool easy to use with a bunch of pre-defined and easily configurable widgets Interface. Cause as it is, there is absolutely no way I'm going to invest the time necessary to develop my own set of interface tools, and rethink available would be a complete pain in the end without an interface generator.

    -RIM, really so little to invest in to make life easier for developers it is? If so, its really not great mystery why it's market share is so dismal.

    Any suggestions appreciated

    Thank you

  • Dynamics of the instructions for the training simulation

    I'm looking for some advice with an idea for a dynamic list step by step for a training created in 7 Captivate simulation.

    The behavior by default when you create a simulation of guided training is for the steps appear in a text box is close to the click box. Instead, I want to stack the instructions step by step in a Panel on the left side of the screen that was sitting next to the interface simulated on the right side of the screen. All high-level steps could not be visible throughout the simulation, and every step in the list of the Panel would have highlighted where appropriate.

    I started with Knockout blog post of the Lilybiri ('create and use a Master 'Knockout' Blade'), which appears as a possible solution, but I have not yet arrived at the point to add my dynamic instruction Panel.

    In essence, the dynamic panel will work as follows:

    • Step 1 in the instruction Panel is highlighted at the beginning of the simulation.
    • Clicks of learning partners step 1 box click in the simulation interface (as shown in the instruction Panel).
    • During the click on box 1 click the step, step 2 in the instruction Panel is highlighted and step 1 highlight disappears.
    • Clicks of learning partners step box 2 click in the simulation interface (as shown in the instruction Panel).
    • And so on through all the steps listed in the instruction Panel.

    I work to make fun of something using variables and stocks advanced to reach the Panel of dynamic education and you want to superimpose on the left side of the screen. I think he would sit at the top of the left panel in the hole.

    Different positions, I saw that it is not advisable to insert a Captivate SWF in another project file, it seems that the Knockout of Lieve approach is the way to go. I am pleased to address the technical aspects of this on my own, but first of all, I would like to confirm that it is even possible with Captivate, or if it would be better to use a Flash. A that someone is doing something similar, or if someone sees no problem with this approach?

    Any comments or suggestions would be greatly appreciated!

    Thanks in advance!

    I think it is possible, Nancy, but not easily, and doubt that you will get complete instructions in this forum. What Captivate version do you use?
