(Battery life is approximately 5 years at 25°C.)CPU Unit failure (watchdog timer), I/O bus error, battery error, and memory failureProgram checksNo END instruction, programming errors (checked when operation is started)Note301. The DM area, HR area, AR area, and counter values are backed up by theCPU Unit’s built-in battery. If the battery is discharged, the contents of theseareas will be lost and the data values will revert to the defaults.2. The contents of the program area, read-only DM area (DM 6144 toDM 6599), and PC Setup (DM 6600 to DM 6655) are stored in flashmemory.
The contents of these areas will be read from flash memory thenext time the power is turned ON, even if the backup battery is discharged.When data has been changed in any of these areas, write the new values toflash memory by switching the CPM2A to MONITOR or RUN mode, or byturning the power OFF and then ON again.Section 2-1Specifications2-1-3 I/O SpecificationsCPU Unit Input SpecificationsItemInputsSpecificationAll24 VDC +10%/–15%OFF voltage/currentIN00000 to IN00001IN00002 to IN00006IN00007 and upIN00000 to IN00001IN00002 to IN00006IN00007 and upIN00000 to IN00001IN00002 and upAll2.7 kΩ3.9 kΩ4.7 kΩ8 mA typical6 mA typical5 mA typical17 VDC min., 5 mA14.4 VDC min., 3 mA5.0 VDC max., 1 mAON delayAll1 to 80 ms max.
