SB BA01 Battery board
The S7-200 SMART SB BA01 battery board is designed for long-term backup of the Real-
time clock. It is pluggable in 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.
The battery (type CR1025) is not included with the SB BA01 and must be purchased by the
user.
Note
The SB BA01 is mechanically designed to fit the CPUs with the firmware V2.0 and later
versions.
