• 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.

• 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.

  Hi Jigar273,

  (1) have you configured MATLAB to use the compiler to MSVC ++ 2008? If not, then just type mex - configure in the MATLAB command window and follow the printed instructions.

  (2) open Windows command prompt and type % NIVERISTAND_ROOT, and then press ENTER. The call to this environment variable returns C:\VeriStand? If this is not the case, then please add this environment with the value of C:\VeriStand variable to your system and restart the PC. To do this, follow the instructions as described in the link: http://support.microsoft.com/kb/310519

• 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.

• What is the best approach to the conversion of the LV7.1 tags to the variables shared by several screws LV2012?

  What is the best approach for the upgrade of the DSC-LV2012/LV7.1/DSC static variable tags in several screws running on several platforms? Our system is made up of about 5 PC running Windows 2000/LV7.1 DURATION, the more a PLC and a PDC running XP/SP3/LV2012. About 3 PC publish information from the sensor through tags on the local network to the PDC. Only the main command is currently being upgraded. Basic questions:

  1. the other computers running RTÉ 7.1 (with labels) will be able to communicate with the PDC running 2012 (shared variables)?

  2. is it necessary for conversion of tags shared variables, or the deprecated legacy tag screws of LV7.1 work in LV2012?

  3 all of the main controllers will be screw must be integrated in a project in order to use shared variables?

  4 is the only way to do it is to find all the tags and replace them with elements of shared variable?

  Thank you in advance with all the information and advice!

• 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

  Pawel

  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.

• How to interface a simple way using LabVIEW 2009 simulink model and SIT?

  Hello

  I finally found a way to use a template simulink with LabVIEW and the Toolbox to SIT, but I'm not satisfied.

  If you have any suggestions, the link of resource that I missed, please do not hesitate to answer

  Note that I do not know much about simulink, so that is my question seems stupid, let me know what

  Software configuration

  OS: Windows (not an RT target)

  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

• 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.

• Problem starting on several Satellite C50 - C70 models

  The members of the forum and Toshiba, Hello

  Recently, I sold several laptop Toshiba Satellite C50-70 and Satellite Pro series.

  With most of them, I knew starting problems.
  When turn on/off the laptop, I see the Toshiba Logo and then nothing happens.
  I have to turn it on and turn it on again so he can start on Windows. (7 or 8.1)

  Sometimes, I have to power OFF / ON several times.

  What I see is that the NumLock light does nothing. If the system starts, I see this LED flashes on / off 2 times. So, I can see on forehand if the laptop to boot Windows or hangs at the Toshiba Logo.

  Anyone having the same problems?

  I put t know if anyone has had this problem but I guess that if the books are new and covered under the Toshiba warranty, you must contact the maintainer authorized Toshiba in your country to check the material part.

  The Toshiba start screen freeze means that the POST (power on self-test) could not be transmitted correctly and it is especially a sign of hardware malfunction.

• Create several screws using a loop for

  Hello

  I am still fairly new to LabVIEW, that this issue might be easy for you guys here...

  I'm going to simplify what I'm doing.

  I have two digital controllers who act as the rows and columns of a matrix.

  I would take those figures of these two controllers and use them to create a matrix of a certain image.

  Example:

  The controller of lines is 3, and columns controller has 4.

  Using these numbers, I would like that the final result to show a certain image (say, a cube) on a matrix of 3 times 4.

  Let's say that the image is an X, then the end result should be:

  XXXX

  XXXX

  XXXX

  I think I should use a double loop for (one inside the other, obviously), and I should also create the 'position' property to display each image of the cube to its rightful place.

  The problem is that I don't know how to CREATE the images over and over again, while being able to control the position of each property.

  Any help would be GREATLY appreciated!

  These small 'boxes' (key word being little) are simply called under screws.  Express vIs are large blue abominations that take valuable real estate and are intended to make life easier for you.

• ISI t possible to use several screws with state diagram module

  Hello

  I'm doing a request using the module state diagram, and I have to use at least for VI I developed. I have problems when I want to set the entries before creating different States. My VI have stop buttons and the e/s I need to use. I have the same problem with the outputs. Because I can not set the input/output (type moore machine) I can't nor define the guards and actions that the state machine must fallow.

  You have an idea if we can use several VI with this module or do I have to use the good old box + all state machine technique.

  Thank you.

  Of course, this is possible.

  

  hope this helps,

  Hey,.

  It depends on what version of SIT you use.

  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

  With earlier versions, you need VS. 2006.

  Now, when you run this CP you should have by default like T1 only.

• 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

  Thank you
