The S7-200 SMART SB BA01 battery board provides for long-term backup of the real-time
clock. The battery board plugs into the signal board slot of the S7-200 SMART CPU
(firmware V2.0 and later versions). You must add the SB BA01 to the device configuration
and download the hardware configuration to the CPU for the SB BA01 to gain access to the
additional battery health reporting options.
When you purchase the SB BA01 battery board, it does not include the battery (type
CR1025). You must purchase the battery separately.
Note
The SB BA01 is mechanically designed to fit the CPUs with the firmware V2.0 and later
versions.
