- Description
The Siemens 6ES7297-0AX30-0XA0 is a SIMATIC S7-1200 Battery Board BB 1297, a plug-in board for the signal-board slot of an S7-12xx CPU (firmware V3.0 or higher) that buffers the real-time clock over long power-off periods using a CR1025 battery, which is not included. It is rated IP20 and weighs 40 g.

Selection Notes
This board only makes sense on installations where the RTC must survive extended power-off periods beyond the CPU's own 480-hour capacitor backup; short outages don't need it. Because it plugs into the signal-board slot rather than a full expansion slot, adding it does not reduce the CPU's signal-module or communication-module count. The CR1025 battery ships separately, so it has to be ordered alongside this board to be functional.
