[TRNSYS-users] Building a TRNSYS DLL to couple run Simulink and TRNSYS

[David BRADLEY]

Mustafa,
   The TRNSYS kernel and TRNSYS types communicate with each other in a 
fundamentally different way between Trnsys16 and Trnsys17. In Trnsys16 
the kernel passed certain pieces of relevant information (like the list 
of parameters, inputs, outputs, and certain flags for where the 
simulation is in its overall process) to the Types whereas in Trnsys17 
the Types query the kernel for the information that they need. That 
said, the Trnsys17 kernel is able to communicate with Trnsys16 Types 
using the "passed information" method so long as the Types identify 
themselves as being written using the Trnsys16 coding standard. I don't 
think that the problem you are facing lies here. More likely the issue 
is in either the compiler project settings not matching up with those of 
the Visual Studio Fortran project that is used to compile the DLL or 
that your project cannot access the compiled libraries that contain the 
definitions of all the functions and data structures that your Type 
needs but that are contained and declared in the TRNDLL. I have not 
written any C++ components for TRNSYS so I am afraid that I can't offer 
any hints on how to resolve the problems. If any other users have 
experience with this, I would greatly appreciate hearing about it.
kind regards,
  David
