They make all this so proprietary I can't dig up any schematics or data regarding the internal workings of either the Fast Tool or this Allen Bradley. If I had more time and attention span I'd attempt to reverse engineer Kone's KST DMC tool to understand the coding and how it communicates but two small kids and a wife dictates my time otherwise. Also, I've been mainly wanting to poke around KST exe files with a reverse engineering app.
