Using simulink models with CompactRIO 9012

[MihaiC]

Good day,

I am experiencing some problems in using simulink models along with cRIO 9012 RT controller + RIO 9104.

I am using LabVIEW 2009 on a WindowsXP machine, Microsoft Visual Studio 2008, Matlab 2009a.

I have followed the instructions from SimulationInterfaceToolkit 2009 install directory:

"Add the following three files to support SIT on VxWorks.  

 - X:\SimulationInterfaceToolkit\2009\ModelInterface\tmw\R13\nidll_vxworks.tlc

 - X:\SimulationInterfaceToolkit\2009\ModelInterface\tmw\R14\nidll_vxworks.tlc

 - X:\SimulationInterfaceToolkit\2009\ModelInterface\tmw\R2007b\nidll_vxworks.tlc

Add the following three files to support SIT on VxWorks.   - X:\SimulationInterfaceToolkit\2009\ModelInterface\tmw\R13\nidll_vxworks.tlc - X:\SimulationInterfaceToolkit\2009\ModelInterface\tmw\R14\nidll_vxworks.tlc - X:\SimulationInterfaceToolkit\2009\ModelInterface\tmw\R2007b\nidll_vxworks.tlc"

I've downloaded the Wind River VxWorks "updated_vxworks63gccdist.zip" as refered in "Developing Shared Libraries for the cRIO-901x and Other VxWorks Targets".

I've tried 2 simple simulink models, the simplest is summing 2 inputs and displaying the result. In the simulation mode, the SIT manager works well and I can both have control and view the result.

The second example I've tried is an artificial neural network which output follows the input. Here also, I have control of the input and view the result correctly.

As I am selecting the "nidll_vxworks.tlc" and the "nidll.tlc" in the Real Time Workshop from Matlab, the vxworks gcc compiles the 2 models without any error.

I've put the *.out and the *.dll files in the same directory for automatic upload to the controller.

Switching to SIT manager in LabVIEW, i select the Real Time hw- cRIO 9012, and *.dll as the model DLL. I RUN the model, some files are deploying to the controller but some error occurs:

For the second example, the one with the ANN, as I select the model DLL file an error occurs and I loose access to the output of the model. The artificial neural network however has intermediate points where i can view the data so I map the display output to any one of them. 

As with the first example some deployments are made to the controller but errors occur:

With a FTP file manager I navigate to the ni-rt/system folder of the cRIO 9012 and I can see the *.out files deployed. 

However something isn't working well.

Is something that i'm missing?

I mention I don't have the LabVIEW 2009 SP1 or SimulationInterfaceToolkit 2009 SP1 installed, where I saw that some bugs are resolved. 

The SIT 2009 read-me states that it has support for VxWorks targets.

It looks like you do not have the shared variable engine loaded onto your cRIO. Open MAX and install the variable engine support onto your target.

[MihaiC]

Hi Scott W,

Thank you for the answer. It wasn't the variable engine but the Simulation Interface Toolkit the one not installed. It works now.

If you are kind I do have another questions:

1. The ANN model I've developed in Matlab lost it's output connection when I switched from *.mdl to *.dll file. The model has masked and linked blocks. It's that why I lost the Output mappings to the model?

2. It is possible to call the *.out files on the VxWorks target without using the SIT?

For example I want to use the ANN model in a bigger project. I'd like to call the library with "Call Library Function Node" and use the inputs and outputs of the model to interface LV code. 

In the KnoledgeBase "Calling external code on VxWorks Targets" it's stated that "...the LabVIEW development environment cannot read the library information in VxWorks shared libraries, and configuration of the Call Library Function Node must be done with a stub DLL." 

Thank you,

Mihai C.

Hello.

I am having the same issue with SIT and a cRio9073.

Do I need to install the Simulation Interface Toolkit on the cRio then?

When I go to MAX I don't see the option to install the toolkit.

Any advice will be greatly appreciated.

Hello,

You will need to complete a 'Custom Installation' in order to select SIT as an option to install on the cRIO. See the attached pictures to see which selections you should make in the Software Wizard dialogue box. Hope this helps.

Best,

Patricia B.
