Please proceed as follows:
S
Transfer the necessary cycles from the directory
CYCLES\SC\PROG\TEMPLATES to the user cycles directory.
S
Assign the M functions to cycles in the following machine data:
MD 10715 $MN_M_NO_FCT_CYCLE[n] = Number of M function
MD 10716 $MN_M_NO_FCT_CYCLE_NAME[n] = Name of cycle
S
Execute a "Power ON" in the NCK.
