Glossary
Battery The buffer battery ensures that specified data areas, flags, timers and counters are re-
tained retentively.
Bay controllers Bay controllers are devices with control and monitoring functions without protective
functions.
Bit pattern indica-
tion
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.
BP_xx → Bit pattern indication (Bitstring Of x Bit), x designates the length in bits (8, 16, 24 or
32 bits).

CFC Continuous Function Chart. CFC is a graphics editor with which a program can be
created and configured by using ready-made blocks.
CFC blocks Blocks are parts of the user program delimited by their function, their structure or their
purpose.
Chatter blocking 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
Combination devices are bay devices with protection functions and a control display.
Combination matrix Up to 16 compatible SIPROTEC 4 devices can communicate with one another in an
Inter Relay Communication combination (IRC combination). Which device exchanges
which information is defined with the help of the combination matrix.
Communication
branch
A communications branch corresponds to the configuration of 1 to n users which com-
municate by means of a common bus.
Communication
reference CR
The communication reference describes the type and version of a station in commu-
nication by PROFIBUS.
