Issue Details

I have generated a Simulink model and would like to call it in LabVIEW. When I use Model Interface Toolkit 2024 Q1 with LabVIEW 2024 and call the library (.dll or .so) file generated from the Simulink model, Error 383200 occurs. How can I solve this error?

 

Error -383200 occurred at Main.vi >> NI_MIT.lvlib:Model Interface Toolkit.lvclass:Load Model.vi >> NI_MIT.lvlib:Model Interface Toolkit.lvclass:Load Library

 

<Additional message>

Model Interface Toolkit: Failed to load file model C:\SimulinkModel.dll


Possible reason(s):

Model Interface Toolkit: Cannot load model. Ensure the Model Library Path is valid and the model conforms to the NI VeriStand Model Framework header file (ni_modelframework.h).

 

Solution

In Model Interface Toolkit 2024 Q1, models generated with the VeriStand Model Generation Support Add-On should be loaded using the generated .vsmodel file. Attempting to load the accompanying .dll or .so file directly may result in Error 383200, as these binaries are not intended to be used as deployment artifacts in this workflow. The legacy VeriStand Model Framework workflow continues to support direct use of .dll files on Windows targets and .so files on NI Linux Real-Time targets.
