This depends which file type on the RJ platform you want to convert to ASCII. There are several extension types on the robot: *.tp, *.sv, *.io, *.df.......etc. TP(teach-pendant files are the most basic, you need a FANUC utility called printtp.exe. To convert sv files you need a utility called kcovars. You cannot covert the *.pc files they are FANUC source code, they have been coverted from ASCII using ktrans to machine language and cannot be converted back to ASCII. You can save the program on using the teach-pendant print file utility, this will convert only tp programs to ASCII, the new extension will be *.ls, use any word editor to view this.
