(1) • Data is backed up from RAM to the built-in flash memory when
changes are made, e.g., from the CX-Programmer.
• When the power supply is turned ON, data is transferred from the built-
in flash memory to RAM.
(2) • A CX-Programmer operation can be used to transfer DM Area initial
values from RAM to the built-in flash memory.
• The PLC Setup can be set so that DM Area initial values are trans-
ferred from the built-in flash memory to RAM when the power supply
is turned ON.
(3) • CX-Programmer operations can be used to transfer data from RAM to
the Memory Cassette or from the built-in flash memory to the Memory
Cassette.
