Veristand Simulink model initialization

VeriStand 2013 has now the ability to initialize the settings of the Simulink model (reference: signals and initial Conditions in a Simulink model mapping).

The question is: is it possible via API in LabVIEW calls?  I would like the user to be able to select the name of the initialization file in my host code.

I have a temporary workaround to have the file name selected by the user copied to a temporary location / name defined in VeriStand System Explorer, but it is certainly not an elegant solution.

Currently, the only way to change the parameter values by default for a system definition is:

1. update the system definition to point to a different file.

2. switch to update the contents of the file that is already stated in the system definition.

#2 looks like the simpler approach recommended for your use case.

One thing that might make your solution a little easier would be to use the index function in the template parameter initialization file. What you can do is the following:

1. (optional) create. that various pattern files of calibration in advance you want to test. Name them sub1.txt, sub2.txt, etc. (or name them as you wish).

2 configure your system definition to point to a calibration of empty template file named Main.txt.

3. prior to deploying your system definition, change the main.txt file to add the following line (assuming that commas here because it's hard to type tabs in a web browser):

Subscript,c:\whatever\sub1.txt

You can also have multiple index files if you want to mix and match. Simply add extra lines.

The advantages of this approach are:

(a) you can easily use the pre-established model calibration files.

(b) you don't have to copy the files autour

(c) the write file you need to do before you deploy is very very simple.

  • How to create a DLL from a .mdl file model to use on veristand simulink

    Hi all

    I want to create a .dll file from a simulink model .mdl file. I created a simple "Sample.mdl" file that adds two entries and gives the result.

    Before you build the .dll, I tried to run file .mdl veristand. Here, I got the below error.

    Method 1: I tried to create a DLL out of it by going to the Simulation-> settings-> workshop in real-time. Here I tried to change the target file system to NIVeriStand.tlc, but I'm not able to see that in the system target file browser dialog box. Can anyone tell me the reason behind that.

     

    Then I tried method 2.

     

    Method 2: I created this .mdl C code using grt.tlc in the Simulation-> settings-> workshop in real-time. I clicked on 'build' button, then he created C equivalent for this code. Using Microsoft visual C++, I tried to generate the .dll file, but I have the following errors.

    Can someone help me on this please. My goal is to launch this model with veristand eithor in.dll or .mdl file format

  • test the simulink model

    Hello!

    I'm currently testing a simulink model in veristand. I import the model into veristand and deploy code to the target. The model seems to work properly.  But I want to measure the time used for the model, I wonder so if it is possible to have a record with tracetoolkit.

    Someone has an idea?

    Thank you...

    Check out this Execution Trace Tool Custom device provided on the page modules VeriStand. Add this device to your system definition file to programmatically configure, start and stop traces of execution that are sent to the host.

    You can examine these tracks to see approximately how long your model is complete by looking for the thread named after your model. For example, if your model is called sinewave, you should see a thread named sinewave_MODEL LOOP. To track the performance of your model, keeping in mind that there are a small amount of additional overhead in the loop of model before program us your model.

  • 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.

  • Several screw-> a Simulink model

    Hi all is there,

    I am using LabVIEW as a UI for a model Simulink.

    According to the user's guide of LabVIEW Simulation Interface Toolkit-> 'using the Simulation Interface Toolkit, you can connect several screws.

    created on the host computer to the same Simulink model.

    And that's what I'm trying to do. I have a Simulink model test3.mdl and I have generated two screws: inputs.vi and display.vi.

    I have traced the commands and views of the two screws for the relevant parameters inside the Simulink model using the SIT connection manager, but trying to run both live and link them to the Simulink model to change the settings and display the results that I get a conflict, alone of the screw can be connected to the model at the same time Simulink.

    Does anyone know what are the steps to connect the two screws to the same Simulink model? SIT documentation claims that it can be done, but unfortunately, it does not explain how it can be done. The only examples are used to connect a vi to the model.

    Thanks in advance

    Jose

    Hi James,

    In the end, I solved my problem with the second option, I told you before: using static variables to pass data between the two screws.

    But it was a little difficult to modify the values of the controls of the façade for the SIT to recognize the change in the value.

    I managed to achieve this by using the following structure for each of the controls of the fron inside the VI Panel where the SIT is running:

    In this case to write the value to the control called "Frequency", I have a variable shared 'f' that is written in the other VI where all data entries will be implemented. Then in the "Frequency" control properties, I bound the control to this variable shared 'f' And the using the structure of the image I managed to do the SIT react against changes in the 'Frequency' control and apply the new value to the Simulink Simulation.

    The truth is that I still do not understand why the SIT does not recognize the change in the control without using all this stuff, but it's working now.

    So could you clarify my doubts about this issue and the problem with the two panels with the SIT fron, that would be great.

    Thank you best regards &,.

  • Problem with Simulink model dll running on target RT

    Hello!

    At the beginning I specify software and hardware that I use:

    LabVIEW 8.5

    Simulation Interface Toolkit 4.0.0

    Microsoft Visual C++ 6.0

    MATLAB 7.4.0 (R2007a)

    NEITHER cRIO-9014

    At first, I did a simple Simulink model (Sine generator, gain and an outdoor sink), then I started with vi empty and abandoned command digital for the gain and the waveform for the sine table. I grabbed SIT Connection Manager and that you have chosen Simulation Environment case. Then I loaded a template file, the mapped controls and indicators. Everything worked like a charm. Problems started when I tried to turn on an RT target. Maybe I'll explain step by step what I did and after the error at the end.

    1. I created a dll from a MATLAB simulink model file. I selected in time real workshop one C language and target to "nidll.tlc". The I compiled without error.

    2. I entered LabVIEW SIT Connection Manager and changed the host execution target in real time. File browser has popped up and I selected the dll already made my template file.

    3. in Add target devices on window, I chose 'existing or peripheral target' and I chose in the other menu in time real CompactRIO. There was my compactrio system, I chose it and LabVIEW began to search for devices.

    4. after that, I clicked the "Ok" button in the SIT connection manager.

    5. I clicked the run button before my vi file panel and LabVIEW began deployment.

    And here the deployment failed with the following error message:

    Deployment of 192.168.1.2 (parameters target successfully deployed)
    Deployment compatOpenFileOperation.vi (5.35 K)
    Deployment of SIT copies values from Replay on Inports.vi (10,96 K)
    Deployment of SIT expand newspapers Signal Names.vi (4.99 K)
    Deployment of SIT PostOutputs.vi
    Could not download SIT PostOutputs.vi
    LabVIEW: Unable to load the shared library SITs.outostOutputs:E on the target RT device.

    I tried to do everything once again and got a little different error message:

    Deployment of 192.168.1.2 (parameters target successfully deployed)
    Deployment of common access to specific Path.vi (22.25 K) path
    Deployment of SIT runtime DLL query.vi
    Could not download SIT runtime DLL query.vi
    LabVIEW: Unable to load the shared library SITs.out:TaskRunTimeInfo:E on the device target RT.

    What I am doing wrong? Any ideas? I will be extremely grateful for the ideas!

    Best regards

    SIT 4.0 does not support VxWorks targets as your cRIO. SIT 5.0 was the first version to have any level of support for this.

    I would recommend contacting support to discuss a possible workaround solution. If they have questions, you can reference this post on the forum and they can contact me. I hope this helps.

  • Mapping to the signals and initial Conditions in a simulink model

    Hello world.  I am pretty competent with old Simulation Interface Toolkit (SIT) and I am moving to Veristand.  I have some basic questions that I think that know the answer, but who want to do some checks.

    First of all, when you map signals, such as the output of a block check, is it possible to make them available for mapping other that mark the test points?  At the bottom of this page, it is a bit ambiguous, but it seems to suggest that if I disable optimization option will appear any sudden without needing me to mark all test points.  The I am referring to something specific is the following, "Certain optimizations that you activate in Simulink can make a not available in NI VeriStand signal. You can disable these options for the entire model to all the signals available to probe, but the model memory footprint increases accordingly.  Alternatively, you can mark individual signals as test points in Simulink to maintain a very reduced memory footprint by keeping test-point available signals to probe. »

    My second question is in what regards the "initial condition" parameters  There was a problem in SIT (although National Instruments has not agree with me at the time that it was a problem), where you can map the controls to these settings, but at the moment where you have been given access to the model, the initialize function had already been called, which means that your maps were useless.  I see that I can still map to these settings in Veristand, and I wonder if the same problem exists.  I'm not quite to the point where I can start trying to change these but I'm hoping to avoid the days of debugging, I lost on this whole by learning to SIT.

    As a follow-up on the second question, to SIT, I could find the C code (located in nidll_main.c) that was called whenever the 'play' button and add a second call to the initialize function.  So let me change the initial conditions without recompiling my entire model which, in my case, would be unworkable. If this problem still someone was able to implement a similar solution?

    Optimization, you can disable in Simulink (TM) I believe is called Signal storage reuse. To my knowledge you either need to use individual test on son points, or you must disable overall re-use of storage of signal for your model.

    Regarding the second question, the question still exists in NI VeriStand. This is something that we are aware of what we expect to address in a future version of NI VeriStand. The workaround you describe might possibly work if you do enough digging in the C code. Currently VeriStand charge and then initializes the model at the same time, and initializing code can read the values of model parameter. If you check out this code and move to the first call to the main function of the calendar, you could allow for the adjustment of the parameters of the model before the model starts.

  • the parameter mapping constant to a control block Veristand simulink block

  • NEITHER Veristand DLL models simultaneous execution

    Hi all,

    I have to solve that problem is with my VeriStand workspace:

    I have a project NIVS with two models of dll (Run/Stop/Pause) execution is monitored in the Versistand workspace by two interface objects user 'Model Control'.

    I wonder if it is possible to manage the executions without a click twice, i.e. together with a click of mouse control.

    I tried to create a custom user interface object whose controls could / should manage all other objects dll controls in the workspace user interface. then I modified 'Model - model Control.vi' with the addition of a "Call by reference" block to call my user object interface custom controls; but an error occurs when trying to load the object in the workspace. The same problem using a Subvi rather than a reference call.

    I hope to be clear.

    You have a solution to this problem?

    Thank you

    Hi, Giulio.

    the fastest way to set values of multiple channels (aka "destinations") with a single source channel is the way user combination and maps. It is:

    (-) In the system Explorer, create a user called channel model batch start.

    (-) Press the button mappings on top and connect the channel the user to both channels of the execution of model, one for each model.

    Bind a control of the workspace to the user of the chain)

    In this way, you can change the execution mode of several models with a single channel model (and thus a mouse click). You can use a Boolean control if you just want to start/stop the model or an entire control if you want better control each State of execution, which are:

    0: start
    1: break
    2: reset
    3: save
    4: restore

    An interface object using custom user is honestly an overdose if you just have to set several values at once.

    Hope this helps

    OS: Windows (not an RT target)

    LabVIEW 2009

    SIT 2009

    question 1: interfacing the model DLL (mapping considerations) with a driver VI

    We have created a model of DLL by using the 'Workshop in real time' tab in simulink.

    In LabVIEW, launch us the tool 'SIT connection manager' and try to use the DLL with a driver VI by mapping the e/s model for screw/lights orders.

    The fact is that I fail to connect to my controls/indicators VI/o model because they do not appear in the mapping dialog box.

    The simulink single objects that I managed to map are "constant" and "test points" while I need to edit the template simulink itself (example below)

    Are in e/s model, not considered as part of the parameters of the model? (this could make sense because the mapping says in fact that it operates on "model parameters")

    Is it possible to link the IO model VI commands/lights?

    Note:

    -the "configure HW i/o mapping" dialog box allows me to map model e/s with e/s HW...

    -The examples also use these "constant" and "test points".

    2nd question: use of direct screw SIT

    I tried to use the DLL directly with the screws SIT (code example below)

    This kind of code works well on another project (target of 8.0/RT LV) but not on the current project (LV 2009/Windows)

    The second stage of the model never ends:

    -0-index of the loop works as expected (model doing its job).

    -index of the loop 1 starts normally, but execution is stuck in the 'SIT scheduler.vi.

    Then I have no choice that to kill LabVIEW ("Reset screws" windows appear if I try to stop/close them).

    Is there a reason that I do not see what explains this behavior?

    Thanks for reading.

    Any help appreciated.

    Kind regards

    Hello

    I spent some time analyzing the VI driver as you suggested.

    Here are my findings.

    Question 1: the SIT connection manager does not pass to the model SW controls/indicators. Only, it allows the user map HW AIs/AOs.

    The only solution I found (to have a SW - for example a shared variable - object that is mapped to an input/output model) is to customize the VI driver that is scripted by the SIT Connection Manager ("_Baserate Loop.vi" in the flat sequence structure named "read code")

    Question 2: after spending some time in the VI driver, it seems that the VI to call right is not 'SIT scheduler.vi' but 'If SIT take model no time' (which uses the other as a Subvi)

    My conclusions are correct? If I use the API in the wrong way, please let me know.

    Kind regards

    With SIT 5.0 and later versions you can use a free compiler as described here:

    http://digital.NI.com/public.nsf/allkb/AAD15283A1F051A1862574F000744DBD?OpenDocument

    Check the XML in your .fpgaconfig and make sure that the values returned by your module HAVE matches the configuration fixed-point.  Looks like your values are currently set to scale by a factor of 16, what could happen if your whole word length is off by 4.  Also make sure you have all the scale applied for channels to HAVE it.

  • Difference between Simulink Inport and Veristand Inport

    I made a simple Simulink model which used default Outport and InPort Simulink and managed to import into Veristand and deploy on RT target successfully.  Recently, I noticed that I have a specific available Veristand in my simulink Library Browser.

    Anyone know the difference?

    VeriStand outport and inport offers two additional features:

    1. you can place an inport or outport VeriStand in a subsystem, and they turn into inputs and outputs in the model that you can map directly to VeriStand, rather than block or out to the subsystem itself.

    2. If you do co-simulation (runs the MDL file directly instead of build in a DLL and running in VeriStand), you can use the VeriStand inports and outports to communicate properly. Since you are a model of compiling and deploying on an RT target, this use case does not apply to you.
