M3, M4, M5, M6, M19, M70, M40, M41, M42, M43, M44, M45.
• For each M function (M0 - M99), there is a dynamic signal at the NC/PLC interface that indicates the validity
(new output) of the M function. In addition, 64 additional signals can be assigned for user M functions.

• For subprograms, machine data can be used to set whether an output of the M function should be undertaken
for the end of the part program M17, M2 and M30 to the PLC:
MD20800 $MC_SPF_END_TO_VDI (subprogram end to PLC)
• For the predefined M function M40 – M45, only limited redefinition of the output specification is possible.
