Glossary
Combination matrix
DIGSI V4.6 and higher allows up to 32 compatible SIPROTEC 4 devices to communicate with each other in an
inter-relay communication network (IRC). The combination matrix defines which devices exchange which in-
formation.
Communication branch
A communications branch corresponds to the configuration of 1 to n users which 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 con-
tainer.
Control display
The image which is displayed on devices with a large (graphic) display after pressing the control key is called
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 diagram 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-Technischen-Bundesanstalt
PTB" in Braunschweig. The atomic clock unit of the PTB transmits this time via the long-wave time-signal trans-
mitter 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.
