I am not aware of a way to share logical units between a Fortran DLL and 
a C++ DLL. In case you can't get it to work, I wanted to mention another 
option to handle files in TRNSYS: you can use labels to pass filename(s) 
to your component and then handle file opening, access etc. completely 
in the Type.
This is done in some of the standard Types, e.g. the Matlab link (Type 
155). You can take a look at the code of that component to get a better 
idea of what I mean. Note that the filename handling is done in the 
"ReadParameters" subroutine (~line 500). Also, if you open the CVF 
project and look for Type 155, it is in a separate project (i.e. in 
"Type155 files", not in "TRNDll files".

I hope this helps,
