Function Manual, 11/2006, 6FC5397-0BP10-2BA0
Application
Controlling machine functions in synchronism with the part program.
General remarks
• The following M functions have a predefined meaning: M0, M1, M2, M17, M30
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.
•
The predefined auxiliary functions M0, M1, M17, M30, M6, M4, M5 cannot be redefined.
