7 M-functions

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 available.
