(flag memory range). You can use specific character strings to express memory position and size. For the M flag memory
range in AX-3 Series PLC, you cannot manually use the bit operation when in online mode.

Memory Area
The numbering that you use for addressing the memory position depends on the target system. Before specifying the
address value in the memory area, you need to know the mapping corresponding relationship of devices to prevent the
overlapping memory ranges. See the table below for reference.
