• MD10718 $MC_ M_NO_FCT_CYCLE_PAR = <Index>
Programming
Rules for replacing M functions:
• The replacement subprogram is called at the block end
• Within the replacement subprogram, no M functions are replaced
• In an ASUB, the M function is also replaced if the ASUB was started within the replacement subprogram.
M functions that cannot be replaced
The following M functions trigger system functions as pre-defined auxiliary functions and must not be replaced by
a subprogram:
• M0, ... M5
• M17, M30,
• M19
• M40, ... M45
• M98, M99 (only for MD18800 $MN_MM_EXTERN_LANGUAGE ≠ 0)
User-specific M functions parameterized via machine data must also not be replaced by a subprogram as they
also trigger system functions.
Note
For an M function replacement with transfer of information via system variable, the
address extension and function value of the M function must be programmed as constant
values.
Permissible programming:
•
M<function value>
•
M=<function value>
•
M[<address extension>]=<function value>
Illegal programming:
•
M=<variable1>
•
M[<variable2>]=<variable1>
