I have created a .dll file (see fig: PID_win64.dll) and associated headers (see fig: in PID_ert_shrlib_rtw) with the aid of Simulink (see fig: PID.slx). I now want to call it in a simulink model (see fig: test_dll.slx) where I am going to test it. I have read in older posts that I have to use S-Function block. Please let me know if this is the proper route I should follow and if so could you please share with me the exact steps (where should I allocate the name of dll and headers - which headers) ?

The final aim is to import the created .dll file in DIgSILENT POWERFACTORY. If anyone can share any further information regarding this would be highly appreciated.

hi, i have the same quesition. Have you solved your problem? I have a DLL (compiled from visual studio), i want to know, how can i call it in Simulink. This DLL was also used in Powerfactory.

Hello,

I have the same question. I have generated a dll using embedded coder.I want to test this dll before I send it further to be used in Powerfactory. I tried some links from forum but didnt reach the goal. Can anyone help me on this if you have developed any solution that i can follow. thanks

Yes, creating an S-Function one possible approach. I presonally prefer the legacy_code tool, but S-Function builder will also work.

Note that you can also call C code in a DLL from a MATLAB Function block using the coder.ceval() function.

Same here. Given the attention of this post, can Mathworks offer a target specifically for exporting DLLs from Simulink that are compatible with DigSILENT Power Factory?
