Up to 100 miscellaneous functions (M functions) can be programmed in HEIDENHAIN contouring
controls. The code for these M functions is transferred to the PLC either before or after execution
of the NC block. A number of these M functions have a fixed meaning for the NC. These M
functions are marked with * in the following table. The other M functions are freely assignable.
