Component view In addition to a topological view, SIMATIC Manager offers you a component view. The
component view does not offer any overview of the hierarchy of a project. It does, how-
ever, provide an overview of all the SIPROTEC 4 devices within a project.
COMTRADE Common Format for Transient Data Exchange, format for fault records.
Container If an object can contain other objects, it is called a container. The object Folder is an
example of such a container.
Control display The display which is displayed on devices with a large (graphic) display after you have
pressed the control key is called the control display. It contains the switchgear that can
be controlled in the feeder with status display. It is used to perform switching opera-
tions. Defining this display is part of the configuration.
Data pane
→
The right-hand area of the project window displays the contents of the area selected
in the
→
navigation window, for example indications, measured values, etc. of the in-
formation lists or the function selection for the device configuration.
DCF77 The extremely precise official time is determined in Germany by the "Physikalisch-
Technische-Bundesanstalt PTB" in Braunschweig. The atomic clock station of the PTB
transmits this time via the long-wave time-signal transmitter in Mainflingen near Frank-
furt/Main. The emitted time signal can be received within a radius of approx. 1,500 km
from Frankfurt/Main.
Device container In the Component View, all SIPROTEC 4 devices are assigned to an object of type
Device container. This object is a special object of DIGSI Manager. However, since
there is no component view in DIGSI Manager, this object only becomes visible in con-
junction with STEP 7.
Double command Double commands are process outputs which indicate 4 process states at 2 outputs:
2 defined (for example ON/OFF) and 2 undefined states (for example intermediate po-
sitions)
Double-point indi-
cation Double-point indications are items of process information which indicate 4 process
states at 2 inputs: 2 defined (for example ON/OFF) and 2 undefined states (for
example intermediate positions).

Drag and drop Copying, moving and linking function, used at graphics user interfaces. Objects are
selected with the mouse, held and moved from one data area to another.
Earth The conductive earth whose electric potential can be set equal to zero at every point.
In the area of earth electrodes the earth can have a potential deviating from zero. The
term "Earth reference plane" is often used for this state.
