11.6.4.12 M Code

Function: Interacts with general programs.

Format: N_ M_ D_

Parameter Explanation:
N_
：
The row number of M code in NC program
M_
：
The number of M code, range: 0~99
D_
：
Output parameter, data type: LREAL.

Instruction Explanation:
1.
D_ can be omitted and then no paramter is output after M code is executed.
2. Two methods of using M code: one is to write it outside the row of G code; the other is to write it
in the row of G code.
3. When M code and G code are not in the same row, e.g. N0 M10 D10.02
；
N1 G1 X100 Y100.
When arriving at the row N0, G code exution will stop. Meanwhile, DMC_ReadMFunction is
used to read the state of M code, MFuntion is TRUE and the value of MFunctionValue is 10.02.
After M code is reset by using DMC_ResetMFunction intruction, G code execution will continue
and then N1 row will be executed.
4. When M code and G code are in the same row and M code can only be placed after G code,
e.g. N0 G1 X100 M10 D10.02. When the execution arrives at N0 row, G1 is executed.
Meanwhile, DMC_ReadMFunction is used to read the state of M code, MFuntion is TRUE and
the value of MFunctionValue is 10.02. The following execution will continue after G1 execution is
finished and reset instruction will no be needed to reset M code.
