Example 2 The following program just outputs M code 600. (M codes over 499 don’t inter-
lock.)
N000 P000 X
N001 G01 X100 F100 M600

5-6-5 Effect of Mode Changes on M Code Resets
The status of M codes isn’t affected by switching from manual to automatic mode
or vice-versa.
5-6-6 Clearing M000 to M499 with Forced Block End or G74
The M strobe and M code outputs for M codes 000 to 499 will be cleared if the
program block that outputs the M code is cleared with the Forced Block End sig-
nal (PC data area interface bit) or the OPTIONAL END function (G74).
