Maurice,
As soon as you call the TRNExe64.exe, it calls the TRNDll64.dll so I don't think that the communication is going to get any faster since Trnsys is already a dll. The *.exe part of TRNSYS is mostly occupied with the online plotter so if you get rid of all the Type65s in your simulation it will run a bit faster. However, if you have already used the /h switch then that is about as fast as it is going to get.
kind regards,
David

What you advise is what I did:arg1 = directory where TRNSYS.exe isarg2 = name of the DCK file
arg3 = "/h" (to avoid that window open the interface)exe_trnsys = subprocess.call([arg1,arg2,arg3])
but it is very slow. A better way will be to have a .dll

Objet : Re: [TRNSYS-users] ddl or api for trnsys.exeMaurice,
I have not used Python, however, TRNSYS can be called from the command line so I assume it would be able to be called from Python as well. The command line to run one of the TRNSYS examples is:
c:\Trnsys18\Exe\TRNExe64.exe "c:\Trnsys18\Examples\Calling_Contam\CombinedThermalAirflow_AHU.dck"
if you add a /n at the end of the line then there will be no need to click "ok" when the run completes.
if you add a /h at the end of the line then TRNSYS will run entirely in the background.
kind regards,
David

Hi,
I am using TRNSYS for industrial development. For this purposes I develop a program in Python language which calsl TRNSYS.exe via subprocess function. It takes a lot of time because it means running via Windows.
Does it exist a code (something like an API or a DLL) which can be called directly from Python ?
Best regards
Maurice
