Battery Monitor
This section describes the battery monitor function that monitors the voltage of the FC6A Series MicroSmart backup battery.
Function Description
You can know when to change the backup battery before it dies by monitoring its voltage. The battery voltage in mV as measured
after the power is turned on is stored in a special data register (D8056), and the battery level status is displayed on the battery
status LED [BAT]. The battery voltage can also be measured at any time.
If the battery dies, device values are reset to their initial values when the power is turned off. Replace the backup battery before it
dies.
Battery voltage (D8056)
Stores the measured battery voltage in mV. The battery voltage fluctuates according to the usage environment.
When the power is turned on, this value is 65,535 until the initial battery voltage measurement has completed.
This value is 0 when there is a measurement error or when there is no battery.
Battery voltage measurement (M8074)
Shows the battery voltage measurement status.
0: Battery voltage measurement completed
1: Battery voltage being measured
The battery voltage can also be measured by writing 1. The measured value in mV is stored in D8056. The value is reset to 0
when the measurement has completed.
Battery level indicator
The status of the battery level is displayed on the battery status LED [BAT] according to the battery voltage value.
Battery Status LED [BAT] Condition Battery Status
Off Battery voltage (D8056) > 2,300 Normal Sufficient battery level.
Blinking (1 s cycle) 2,300 ≥ battery voltage (D8056) > 2,000 Warning Low battery level.
On 2,000 ≥ battery voltage (D8056) Dead battery The battery is almost dead. Or no battery.
