You have to use an older version of Visual Studio.
Here are the limitations of the OPC functionality according to Dymola User Manual Volume 2 in Dymola 2019 FD01:
- You must run Dymola with administrator rights to be able to run the OPC server.
- Currently only the solvers Lsodar, Dassl, Euler, Rkfix2, Rkfix3 and Rkfix4 are supported.
- Only Visual Studio 2008, 2010, and 2012 compilers are supported.
- Dymosim with OPC server is always built as a 32-bit application.
- OPC Server cannot be combined with Export model as DLL.
