TLC of M-S Function or workaround

What is the best way to include Matlab-Function in Simulink and make it ready for Code generation?

I wrote some Function in Matlab to Connect Matlab it with a SPS. This Function are Shadowfunction, who use MEX by running in Workspace and CPP by running in Matlab Coder.

Now I like to have the function in Simulink and also ready for coding. I created M-S-Function Level 2, in it I call the Shadowfunction. During simulation, it works fine. But I can not create code from it, by using the Simulink coder. I get following Error:

The corresponding 'mlpiConnectionBlock.tlc' file for the MATLAB S-function 'mlpiConnectionBlock' in block 'MSFunction/mlpiConnectionBlock' must be located in the current working directory, the MATLAB S-function directory 'C:\...\Simulink', or the directory 'C:\...\tlc_c'

I know, TLC files are not trivial. Exist a better way for easy including? If not, can someone help me with the TLC file? The S-Function "mlpiConnectionBlock" has one boolen Input, one uint32 output and one parameter (string).

M-S Function:

function Outputs(block)
%rising edge. Only one time
if (block.Dwork(1).Data == 0) && (logical(block.InputPort(1).Data) == true)
    ipaddress = char(block.DialogPrm(1).Data);   

      block.Dwork(1).Data = mlpiApiConnect(ipaddress);%shadow

elseif (block.Dwork(1).Data ~= 0) && (logical(block.InputPort(1).Data) == false)      
    %falling edge, only one time

     mlpiApiDisconnect(block.Dwork(1).Data);  %shadow

      block.Dwork(1).Data = uint32(0);
  else
     % do nothing
  end

block.OutputPort(1).Data = block.Dwork(1).Data;
%end Outputs

Shadow-Function example:

function [con] = mlpiApiConnect(ipAddress)

if isempty(coder.target)
    % running in MATLAB
    con = mlpiApiConnectMex(ipAddress); %call MEX
else     
    % running in the generated code
    con = uint32(0);
    ipAddress = [ipAddress 0]; %terminierungszeichen    
    con = coder.ceval('mlpiApiConnectCoder',ipAddress);    %call LIB
end

did you found any solution because I'm having similar problem, i have level 2 s-function that i wish to run in External mode for windows real time target.

Since you already have code that is compatible with MATLAB Coder, you can simply call your function using a MATLAB Function block, which automatically supports code-generation as long as you are able to generate standalone code from your code using MATLAB Coder. You don't have to worry about writing an S-function or its TLC file.

But if I like to run the toolbox in non-realtime only in the Simulink-Simulator, I need the Simulink-Coder license. But I like to need the license only for Code generation.

[Kaustubha Govind]

You won't need a Simulink Coder license to run the MATLAB Function block in normal mode simulation. You can verify this by starting a fresh session of MATLAB, run your model in normal mode and see the list of license checked out using:

>> license('inuse')
