Design Notes

VSS/LabVIEW Integration Example

This example illustrates co-simulation with LabVIEW and MATLAB® in VSS. Co-simulation with LabVIEW is achieved by implementing the required functionality into a LabVIEW Virtual Instrument (VI); the Matlab implementation is done through a .m file.

...

In this project, the same input signal is passed through the VSS MTD block,  the LABVIEW block running the MTD.vi, the LABVIEW block running MTD_MathScript.vi and the MATLAB block calling the MTD.m function. The outputs are plotted and compared to verify they are all identical.

Note 1: This example will not run using the LabVIEW Run-Time Environment since the LabVIEW MathScript RT add-on module is not compatible with it.

Note 2: To link to the appropriate LabVIEW version, the variable TCPPORT in the LABVIEW blocks should match the setting of TCP/IP Port in LabVIEW Tools/Options.../VI Server.
