Purpose
Accommodates the backup battery
The backup battery sustains the power supply to the internal memory
in the event of S5-95U external power failure/power off.
The front connector is the terminal block for the signal lines of the digital
inputs (I 32.0 to I 33.7) and outputs (O 32.0 to O 33.7) and it establishes
the connection to the S5-95U.
If this LED lights up, the backup battery is discharged.
Switches the S5-95U on or off.
