2.2.5.10 Battery compartment
The battery compartment consists of the battery holder and the battery.
The lithium battery (3 V, 1000 mAh) ensures backup power to the internal real-time clock (RTC). It is located on the
underside of the device behind the gray cover. The self-discharge time of the battery is at least 8 years (at 50°C,
6 μA for the components being supplied). The battery is subject to wear and should be replaced regularly (at least
after the specified service life) by changing the battery (see
"Changing the battery" on page 286
).

Table 49: Battery compartment
The battery state is determined by the system immediately after the device is switched on and subsequently every
24 hours. During the measurement, the battery is subjected to a brief load (approx. 1 second) and then assessed.
The determined battery state is displayed in BIOS (see
) and the B&R Control Center
(ADI driver) but can also be read out in a customer application via the ADI library.
Battery state
Explanation
N/A
The hardware or firmware used is too old and does not support readout.
GOOD
Data retention is ensured.
BAD
As soon as the battery capacity is recognized as BAD (insufficient), the battery compartment must be replaced.
Table 50: Explanation of battery state
As soon as the battery capacity is recognized as insufficient, the battery compartment must be replaced.
To avoid data loss during battery replacement, data is retained by a capacitor for approx. 2 minutes.
