4.4.11 File Register R, ZR

 As with the data registers, the file registers are memories used to store data. However, there are some that have fixed
applications, and those that are released.
The file register has a 1-point 16-bit configuration, and can be read and written in 16-bit units.
To handle 32-bit data, two points must be used. The file register No. designated with the 32-bit instruction will be the low-
order 16-bit, and the designated file register No. +1 will be the high-order 16-bit.

Data storage
High-order 16-bit
 The data that is stored once in the sequence program is held until other data is stored.
 With the file registers, the following registers are the user release.
R8300 to R9799 Data are not cleared even when the power is
turned OFF.
R9800 to R9899
R18300 to R19799 Data are not cleared even when the power is
turned OFF.
R19800 to R19899
R28300 to R29799 Data are not cleared even when the power is
turned OFF.
R29800 to R29899
The other file registers have fixed applications such as interface of the PLC and CNC, parameter interface, etc., so use
according to the application.
 Values that can be stored:
Decimal -32768 to 32767
Hexadecimal 0 to FFFF
Decimal -2147483648 to 2147483647
Hexadecimal 0 to FFFFFFFF
