Glossary
Communication branch
A communications branch corresponds to the configuration of 1 to n users that communicate by means of a
common bus.
Communication reference CR
The communication reference describes the type and version of a station in communication by PROFIBUS.
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, however, 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 operations. 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 information 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 Frankfurt/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 conjunction 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 positions)
Double-point indication
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).
DP
→ Double-point indication
