5.4.3 Memory capacities of files
The sizes of the files used by the CPU module change depending on their types.
This section indicates the memory capacities of the files for each CPU module.
When files are written to the memory area, the units of the storage capacities change
depending on the target CPU module and memory area. ( Section 5.4.4)
(1) When Basic model QCPU is used
When using the program memory, standard RAM or standard ROM, calculate the
rough size of each file according to Table5.15.
* 1 : 136 is the default value. (It can be increased or decreased by parameter setting.)

Device comment
74 + (sum of comment data sizes of devices)
• Comment data size of one device = 10 + 10250 a + 40 b
• a : Quotient of ((device points)/256)
• b : Remainder of ((device points)/256)
