Siemens SINUMERIK 840Di Function Manual page 681

The following machine data can be used to configure subroutine calls with M, T, and
D auxiliary functions:
Machine data
MD10715 $MN_M_NO_FCT_CYCLE
MD10716 $MN_M_NO_FCT_CYCLE_NAME
MD10717 $MN_T_NO_FCT_CYCLE_NAME
MD10718 $MN_M_NO_FCT_CYCLE_PAR
MD10719 $MN_T_NO_FCT_CYCLE_MODE
MD11717 $MN_D_NO_FCT_CYCLE_NAME
Note
The functions described above are also effective in ISO dialect mode.
Block search response
During block search with calculation and SERUPRO, subroutine calls with M, T and
D functions are executed in the same way as in normal program operation.
M functions that cannot be configured
M functions with a fixed meaning must not be used to call subroutines. The following
M functions have standard predetermined meaning:
M function
M0 to M5, M17, M30, M19, M40 to M45
M98, M99
M functions can be defined for specific tasks using the following machine data. Through this,
they receive a fixed meaning and, therefore, must not be used to call subroutines:
Machine data
MD10714 $MN_M_NO_FCT_EOP
MD10804 $MN_EXTERN_CHAN_M_NO_SET_INT
MD10806 $MN_EXTERN_CHAN_M_NO_DISABLE_INT
MD10814 $MN_EXTERN_M_NO_MAC_CYCLE
MD20094 $MC_SPIND_RIGID_TAPPING_M_NR
MD20095 $MC_EXTERN_RIGID_TAPPING_M_NR
