We intend to use the RT box as a controller to drive a real machine. I would like to know if it is possible to have access to the variables defined in the C-Script without explicitly sending the signals out through the output port? (analogous to the trace file for Matlab S-Fcn in dSpace). The objective is to observe and tune multiple signals in real time.

Any help is appreciated!

No, this is not possible. Variables within a C-Script are only visible within the C code.
