[4] Internal flash ROM and PC card use
All of the control modules in the JW300 series are equipped with FLASH ROM.
This internal ROM can be used to store part of the programs and system memory data in the ROM in
advance, so that the control module will store vital data, even if the back up battery voltage drops.
The models that can also use PC cards (compact flash card, FLASH ATA card) can store data on a
card.
The back up function using these memories can select the back up area, save/load timing, and operation
mode. Set the conditions for use according to your environment and system.
