The DM data will be written to the built-in flash memory.
Note
The DM data that is saved and written at startup is the entire DM Area (D0 to
D32767).

!Caution
The CP1L CPU Units automatically back up the user program and parameter
data to flash memory when these are written to the CPU Unit. Also, the CX-
Programmer can be used to save all of the data in the DM Area to the flash
memory for use as initial values when the power supply is turned ON. Neither
of these functions saves the I/O memory data (including HR Area data,
counter PVs and Completion Flags, and DM Area data other than initial val-
ues). The HR Area data, counter PVs and Completion Flags, and DM Area
data other than initial values are held during power interruptions with a bat-
tery. If there is a battery error, the contents of these areas may not be accu-
rate after a power interruption. If HR Area data, counter PVs and Completion
Flags, and DM Area data other than initial values are used to control external
outputs, prevent inappropriate outputs from being made whenever the Battery
Error Flag (A402.04) is ON.

Overview
CP1L CPU Units have Memory Cassette functions that enable data in the
CPU Unit to be stored on and read from a special CP1W-ME05M Memory
Cassette. These functions can be used for the following applications.
• Copying data to other CPU Units to produce duplicate devices.
• Backing up data in case the CPU Unit needs to be replaced due to any
malfunction.
• Writing and updating data when existing device versions are upgraded.
