3.5 Protection Communication
The Connection via parameter is used to set the bit rate required for the protection interface. Different
discrete values can be entered depending on the means of communication (see following table).

Routing Information in DIGSI 5
Protection communications of the same type form a topology.
For more information on this, see chapter
A data bar is exchanged between the devices of a topology connected via protection communication. This can
be written into or read from by the devices. This can be used for exchanging various signals between the
devices. In this case, each signal demands a certain number of data fields.

The data bar is divided into 3 priorities, which also have different transmission rates and data volumes.
The following basic principle applies for all messages: Only pure data contents are transmitted. The quality (for
example,
Valid ) is not automatically transmitted as well. If you want to transmit the quality as well (for
example, for further processing of GOOSE messages), the quality must be transmitted separately (for example,
by using CFC). If a signal that has a test flag is transmitted (because its function is in test mode, for example),
all signals are provided with a test flag on the receiving side. If the connection is broken, all received signals
are flagged with the quality
