A
Analog I/O
The analog I/O converts analog process values (for example, temperature)
into digital values that can be processed by the C7 CPU or converts digital
values into analog manipulated variables.

SIMATIC S7 range.
B
Back-Up Battery
The back-up battery guarantees that the
stored safe from power failures and that data areas, bit memory, timers and
counters remain retentive.
Back-Up Memory
The back-up memory backs up memory areas of the
need for a back-up battery. The memory backs up a programmable number of
timers, counters, bit memory and data bytes, the
counters, bit memory and data bytes.
Bus
A bus is a transfer medium that connects two or more nodes with each other.
Data transfer can be serial or parallel, via electrical conductors or fiber optic
cable.
