(4) Memory capacity
When a file is written to the memory area, the unit of the stored file depends on the CPU module and memory
area to be written. This unit is referred to as a file size unit.
(a) File size unit for each memory area
The following table lists the file size unit of the CPU module and memory area to be written.
