ROM) automatically writes parameters and programs written to a memory card to the standard ROM.Note2
As shown in Figure 5.29, this function boots programs and parameters from a memory card to the program
memory and writes the booted programs and parameters from the program memory to the standard ROM.
(2) Applications of automatic write to standard ROM
Using this function can write programs and parameters in a memory card to the standard ROM without GX
Developer (personal computer).
This function is useful when:
• the same parameters and programs are written to multiple CPU modules, or
• the same environment is configured at a remote site.
