Siemens 6MD86 - Structure of the Function Group

The circuit breaker [status only] is used only for acquiring the circuit-breaker switch position. This type can be
used to model switches that can only be read but not controlled by the SIPROTEC 5 device.
The available functions are described in the chapters 7 Protection and Automation Functions and 6 Control
Functions.
Structure of the Function Group
Besides the user functions, the Circuit-breaker function group contains certain functionalities that are essen-
tial for general purposes and therefore cannot be loaded or deleted:
•
Trip logic
•
Mapping the physical circuit breaker
•
Circuit-breaker position recognition for protection functions
•
Detection of manual closure
•
General settings
The following figure shows the structure of the Circuit-breaker function group. The individual function blocks
in the image are described in the following chapters.

Structure of the Circuit-Breaker Function Group
The Circuit-breaker function group has interfaces with:
•
Measuring points
•
Protection function groups
Interfaces with Measuring Points
The function group contains the measured values needed from the measuring points associated with this
function group.
