TLC File Level-2 MATLAB S-function

I got a Problem with writing a TLC-File of a Level-2 MATLAB S-function.

I wrote the .m File for the S-function and started the Simulink Model with the Run Button. So far all works well. But now I want to transfer the Model to my Beaglebone Black, so I have to write a TLC File. I looked at the timestwo.tlc example to get Basics in writing an TLC File. In this example is in the TLC File and in the .m File for the S-function the input multiplied by two and transferred to the output. Now my question is if there is a way to get the Values direct from the Simulink Block without implementing the functionality a second time in the TLC File?

Such as:

output_tlc = output_simulink_block

I hope you can understand my Question :-)

Thanks for your Help
