M3B The number of M codes that can be specified in one block
0 : One
1 : Up to three
CAUTION
1 M00, M01, M02, M30, M98, M99, or M198 must not be
specified together with another M code.
2 Some M codes other than M00, M01, M02, M30, M98, M99,
and M198 cannot be specified together with other M codes;
each of those M codes must be specified in a single block.
Such M codes include these which direct the CNC to
perform internal operations in addition to sending the M
codes themselves to the PMC. To be specified, such M
codes are M codes for calling program numbers 9001 to
9009 and M codes for disabling advance reading (buffering)
of subsequent blocks.
The M codes which can be specified in a single block must
be those which the CNC sends the M code signals to the
PMC side.
NOTE
1 CNC allows up to three M codes to be specified in one block.
However, some M codes cannot be specified at the same
time due to mechanical operation restrictions. For example,
M42 can be specified only after the mechanical operation of
M41 is completed.
2 The 1st M code can be up to 8 digits and 2nd, 3rd M codes
can be the values up to 65535.
