Add external routine code to the project files. All calls to external routines require
that you pass an external routine control structure as the first parameter in the
call. The DLL developer must use the Rockwell Automation supplied header file
that describes the control structure. Below is the text of the header file along with
a description of how various parts of the control structure should be used by the
external routine DLL developer.
