You can use the FN17: SYSWRITE function particularly for OEM cycles if you
wish to overwrite certain NC data, e.g., an active basic rotation, from the NC
program. A group number, a system data number, and an index specify the
particular item of system data that you write: FN17: SYSWRITE IDxxxx NRxxxx
IDXxxxx = Qxxx or numerical value; comment. In the NC program you must
enter the code number 555 343 before you can define function FN17 (soft
keys: Q-parameter programming, special functions). After a control reset, the
code number must be entered again if you wish to program FN17. The iTNC
provides the following functions:
