Fanuc previously sold a software product called WinOLPC. I'm told it was something like a programming environment interface. That package was supposed to have the capability to convert the ASCII .LS Listing File to a binary executable .TP Teach Pendant file.
Not certain, but I believe that I was told that the later versions of Fanuc controllers had this capability built-in as a standard function.
