Title and Port Label are only used to label the block. Include Statement inserts code at the top of the generated C code file, to import declarations from a header file. Signature inserts a line directly preceding the expression. This can be used to extern functions or variables. Expression in inserted inline, to update the signal value. Return Data Type must be selected to declare the signal data type in Simulink. The values placed into this block are not checked. A compiler or linker error will occur if there are errors.
