I am trying to generate a Visual C++ project for a 'GRT' target, of a simple model that contains a single OPC read block, and an OPC write block, just so that when I run the simulation in Visual Studio, I will be able to view the output of the model in the real time and also supply new inputs on the fly using Matrikon OPC explorer.
When I try to generate the code, I get the following error:
'The corresponding 'opcslread.tlc' file for the MATLAB S-function 'opcslread' in block 'testGen/OPC Read' must be located in the current working directory, the MATLAB S-function directory 'C:\Program Files\MATLAB\R2012b\toolbox\opc\opcblks\opcblks', or the directory 'C:\Program Files\MATLAB\R2012b\toolbox\opc\opcblks\opcblks\tlc_c''
I have searched in the folders that it specifies, and cannot find the .tlc file it talks about, I heard in earlier releases of Matlab that .tlc files were shipped for every (if not most) sfunction(s), but nowadays they are not.
I am currently running Matlab r2012b if this helps anyone,Has anyone had any experience using Simulink Coder with OPC toolbox, or know how to generate .tlc files or bypass this whole shabang entirely.

I am not 100% sure about the OPC Toolbox, but if the TLC files aren't being shipped, it seems to indicate that the blocks are not supported for code-generation.

I'm having the same problem, although I admit I'm new to using the RTW... Any help here would be welcome.

Problem still exist in the 2016 Matlab version :(
