How to use inlining for S-Function in Simulink with PLC Coder? Or, how to convert C++ code to other languages with PLC Coder?

When I compile my C++code into ST language using the S-Function in Simulink with the PLC Coder compiler,it shows that the PLC Coder supports inlined S-Functions but does not support non-inlined ones.How can I use inlining?Alternatively,how can I convert C++to another language through the PLC Coder compiler in Simulink?

Hi @min,

I faced a similar issue while generating code from an ‘s-function’ block using PLC Coder. I came across a previous MATLAB Answers post, where it was mentioned that PLC Coder does not support generating code from ‘s-function’ blocks, and that the error message might be misleading: https://www.mathworks.com/matlabcentral/answers/725-can-i-generate-plc-code-from-an-s-function-using-plc-coder.

As a workaround, you can try using the ‘MATLAB function block to implement the ‘s-function’ block functionality, since PLC Coder supports code generation from the ‘MATLAB function’ block.

Additionally, if you wish to know more about how ‘s-functions’ can be inlined, please refer to the following documentation link:

I hope this helps.
