Well, the answer is “Yes”. (it is at the end of your question). Just create a Proforma in Studio, and try it out alone (return
42 as output to check it works). Then, add your source to the project (don’t use a separate
compile project for it, it is much easier to use the generated one), and call
your function where it says “call N” to compute the outputs in the TYPEXX()
function, and hand the result back to TRNSYS in the out() array. That’s it, a child’s play. J Werner De : Bezzarga, Amine

you for your quick reply Werner, You
said: “If
you have the source code of the exe, another option would be to recompile it as
a DLL, adding the TRNSYS TYPE function which should then just call the main()
function of your application (you can then easily pass parameters and recover
results).” That’s
a good idea, I tried to do that but can I have more explanation of how do you
do that : “adding
the TRNSYS TYPE function which should then just call the main() ” Because
I tried to recompile my exe into a dll, then link my lib to the new component
project, it compile without problem but when I run the simulation in TRNSYS, I
get this error: 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 : Reported by LINKCK As
you said, TRNSYS is only able to load dll that contain a type (that is
explained in that message) 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 : 1 user DLL was loaded
after searching in "C:\Program Files\Trnsys16_1\UserLib\ReleaseDLLs" So
the question is, how do you add the TRNSYS type function which will call the
main function of my program ? Should
I create a new type with the studio, then add a function wich will do the same
as my exe, and call that function where there is that comment //*** Call N ('normal'
call) ? Thx

[mailto:werner.keilholz@cstb.fr] Hi Amine, ‘Call’ is not the name of a TRNSYS API function, but just a
comment to say that at this point in the example, the C routine is called for
the Nth time. To call an external program in C, you should use the Windows
API. There are many ways to do this, one is to use CreateProcess() function, as
described here: http://msdn.microsoft.com/en-us/library/ms682425(VS.85).aspx One challenge is to make sure the exe has finished before you
try to recover any results it may have put somewhere. If you have the source code of the exe, another option would be
to recompile it as a DLL, adding the TRNSYS TYPE function which should then
just call the main() function of your application (you can then easily pass
parameters and recover results). Hope this helps, Werner De : Bezzarga, Amine
(SCR US EXT) [mailto:amine.bezzarga.ext@siemens.com] Hi everybody, I’m stuck with
TRNSYS v 16.1 , the part of the API that normally
allow to call an external program (an exe written in c++) seems
to not be supported by the C++ plugin (I can just create my
own component that will basically calculate the output from the input) I mean the
linker can’t find the “call” subroutine just like
described in the programmer’s guide of the manual (part 8): 8.4.4.1.
Calling External Programs I know the
example shown is for fortran but, in the file
..\Trnsys16_1\SourceCode\Templates\CppType.cpp we have this at the line 133: //***
Call N ('normal' call) That seems to be
the function that allow me to call an external program, however there is no
reference of that function in the “TRNSYS.h”, So I’m being
stuck with a linker problem. What I want to
do is
to start
a simulation in TRNSYS, then when it reach a certain component, TRNSYS will
call a external program with data (in argument if possible)
and wait for it to finish, and then get back value from my
program? Unfortunately,
TRNSYS doesn’t seem to support Socket connection to exchange data. I see that
type66 do it (This routine calls a program called Engineering Equation
Solver (EES)) with the data exchange protocol via the windows’
clipboard. To resume: So do I have to
start over with the fortran plugin to be able to call external
program? Or do you know
a other way to do what I want ? And do
you think I need to communicate through a file ? Thanks a lot for
your help. Amine |
