*1 Refer to the following for the setting range of usable device numbers(n).
MELSEC iQ-R Motion Controller Programming Manual (Common)
*2  = CPU number (CPU No.1: 0, CPU No.2: 1, CPU No.3: 2, CPU No.4: 3). A CPU number that exceeds the number of CPUs in Multiple
CPU system cannot be set.
*3  = 00h to FFh (Module I/O number  10h). The accessible range differs depending on the module. Refer to the manual of the module
used for details.
• For differentiation, the 32-bit floating-point type is ended by L and the 64-bit floating-point type by F (":F" for the link
register).
• For the 32-bit integer type and 64-bit floating-point type, specify the device number with an even number. (It cannot be set
as an odd number.)
