The buffer battery ensures that specified data areas, flags, timers and counters are re-
tained retentively.
Bay controllers are devices with control and monitoring functions without protective
functions.
Bit pattern indication is a processing function by means of which items of digital
process information applying across several inputs can be detected together in paral-
lel and processed further. The bit pattern length can be specified as 1, 2, 3 or 4 bytes.
→ Bit pattern indication (Bitstring Of x Bit), x designates the length in bits (8, 16, 24 or
32 bits).

Continuous Function Chart. CFC is a graphics editor with which a program can be
created and configured by using ready-made blocks.
Blocks are parts of the user program delimited by their function, their structure or their
purpose.
A rapidly intermittent input (for example, due to a relay contact fault) is switched off
after a configurable monitoring time and can thus not generate any further signal
changes. The function prevents overloading of the system when a fault arises.
Combination devices are bay devices with protection functions and a control display.
DIGSI V4.6 and higher allows up to 32 compatible SIPROTEC 4 devices to communi-
cate with each other in an inter-relay communication network (IRC). The combination
matrix defines which devices exchange which information.
A communications branch corresponds to the configuration of 1 to n users which com-
municate by means of a common bus.
The communication reference describes the type and version of a station in commu-
nication by PROFIBUS.
