10 ROM OPERATION FUNCTION
(b) Operation at applicable data into ROM
When the ROM writing is requested to the Motion CPU module using "ROM
writing" menu of SW6RN-GSV43P, the applicable data into ROM stored in
the internal SRAM are batch-written to the internal FLASH ROM after erase
of an user memory area of internal FLASH ROM built-in Motion CPU
module.
When the writing completes normally, the registration code
(Note-1)
is written
and ROM writing ends.
The process overview is shown below.

(Note-1) : "Registration code" is used to judge whether the programs and parameters written in the internal
FLASH ROM are normal or not.
POINT
(1) When the RAM is selected with "Communication" - "Transfer" menu of
SW6RN-GSV43P, the SRAM memory built-in Motion CPU module is targeted
at the "Installation mode • mode written in ROM" and "Mode operated by
ROM".
(2) The SRAM memory built-in Motion CPU module is targeted at the "Backup •
load" operation of SW6RN-GSV43P. Set the "Mode operated by ROM" after
"ROM writing" for the ROM operation after "Backup • load" at the CPU module
replacement.
(3) The internal FLASH ROM serves as a life in 100000 times writing. If it passes
over a life, "writing error" will occur. After that, replace a module for the ROM
operation.
