12.9 Data/Realtime Buffering

The battery voltage is checked cyclically. The load test of the battery does not considerably
shorten the battery life, instead it gives an early warning of weakened buffer capacity. The status
information, "Battery OK" is available from the B&R-TRAP function, "SYS_battery".
