Memory Backup
The user program and memory area data in the CPU Unit are backed up by either one of the following methods.
• Flash Memory:
User program, read-only DM area (DM 6144 to DM 6599), and PC Setup area (DM 6600 to DM 6655).
• Internal Capacitor:
DM areas other than the above, HR area, AR area, and
Counter area.
The capacitor provides backup for a power interruption lasting
20 days at room temperature. If the power is expected to remain
OFF for a period exceeding this data backup period, consider-
ation must be given to the design of the system so that no prob-
lems will occur when the set values become undefined ones. For
further details, refer to CPM1A Operation Manual (W317).
