1. Program containing many flags (example of instruction execution complete flag M8029)
If you program the instruction execution completion flag M8029 for two or more sequence instructions which
actuate the flag M8029, you cannot judge easily by which sequence instruction the flag M8029 is controlled.
In addition, the flag M8029 does not turn ON or OFF correctly for each corresponding sequence instruction.
Refer to the next page when you would like to use the flag M8029 in any position other than the position just
under the corresponding sequence instruction.
