Destination-columns in Matrix
The engineering is done in the configuration matrix.To allocate information, DIGSI provides two columns as
destination for the system interface
S System Interface with default protection indications (app.10%)
and control indications assigned to logical nodes
X Extended system interface with additional SIPROTEC-
information (app. 90%) and user defined information
(Recommendation) embedded in logical nodes

Destination-columns in Matrix
Which indication/information will be configured with which destination column?
indications/informations described by standard:1.) predefined:
will be configured to Systeminterface S (and cant also be deleted or changed)additionally a configuration to Extended Systeminterface X is possible (so all
indications appear in logical device EXT)
2.) user specific:
will be configured to Systeminterface S, automatically to logical device CTRL,
Extended Systeminterface X is not possible
indications/informations described out of standard:
1.) predefined:will be configured to Extended Systeminterface X, Systeminterface S
is not possible
2.) user specific:will be configured to Systeminterface S, automatically to logical device CTRL
and Logical node GGIO, Extended Systeminterface X is not possible

Application-specific interconnection lists
Interconnections arealways combined in
applications. This is
ideal to keep the
overview even in the
case of a huge
amount of inter-
