[TRNSYS-users] User written type using external DLL
Hello everybody,
I want to write a TRNSYS type (Type203) which has to call a function of an
external DLL (netcdf).
Therefore I have written a test type, which does nothing meaningful. It just
calls a function of the external DLL.
Compiling this type is not a problem, but simulation studio stops with the
following error:
*** Notice at time : 0.000000
Generated by Unit : Not applicable or not available
Generated by Type : Not applicable or not available
TRNSYS Message 199 : TRNSYS found at least one user DLL in the
UserLib directory. (Note: Only DLL's including Types that are used in the
simulation are loaded)
Reported information : 0 user DLLs were loaded after searching in
"C:\Trnsys17\UserLib\ReleaseDLLs"
*** Fatal Error at time : 0.000000
Generated by Unit : Not applicable or not available
Generated by Type : 203
TRNSYS Message 105 : A TYPE was called in the TRNSYS input file but
was either not linked into trndll.dll or was not found in an external dll. A
dummy subroutine was called in its place. Please link the TYPE or remove it
from the input file
Reported information : Type203 could not be located in either the
trndll.dll or in an external dll. Please relink theTRNDll.dll including this
Type or make sure that an external DLL in the \UserLib\DebugDLLs and
\UserLib\ReleaseDLLs folders contain the Type.
, though the DLL of the Type (and the external DLL) is located in the
ReleaseDLLs directory. Furthermore, if I comment the call to the external
DLL out, everything works fine.
Has anyone an idea how to use external DLLs in TRNSYS?
Thanks and best regards
Sven
