Automatic transfer from flash memory to RAM
If DIP switch pin 2 is ON, the function block data stored in flash memory will
be automatically transferred to RAM at startup. This enables battery-free
operation. To prepare for battery-free operation, the function block data must
be store in flash memory in advance using the CX-Process Tool.
Note
Before turning ON pin 2 on the DIP switch, transfer the function block data to
the flash memory using the CX-Process Tool. If the function block data is not
stored in flash memory, RAM data will be overwritten and deleted at startup.
