Siemens SIPROTEC 5 - Overview of Functions

Overview of Functions
The measurands are recorded at the measuring points and forwarded to the function groups.
Within the function groups, further measurands are calculated from these measured values, which are
required for the functions of this function group. This is how, for example, the electric power is calculated
from the voltage and current measurands.
Basic instructions for acquisition and editing process data can be found in the chapter Basic Functional Struc-
ture 2.1 Function Embedding in the Device.
