Glossary
Bay controllers
Bay controllers are devices with control and monitoring functions without protective functions.
Bit pattern indication
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 parallel 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).
Buffer battery
The buffer battery ensures that specified data areas, flags, timers and counters are retained retentively.
C_xx
Command without feedback
CF_xx
Command with feedback
CFC
Continuous Function Chart. CFC is a graphical 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 ON
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
From DIGSI V4.6 onward, up to 32 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.
