Figure 61: IEC 61850: Communication interface principle
IEC 61850 has as a concept for the identification of all signals for communication
that belong to a function by a logical node as a placeholder. All signal information
in command and monitoring direction, which belongs to a function, is available
within the logical node.
Whenever a function block is instantiated in ACT, PCM600 automatically
generates the corresponding logical node data. In
parts per function block. The upper part is the visible function block in ACT and
the lower part is the logical node data for the function block.

GOOSE data exchange

The IEC 61850 protocol supports a method to directly exchange data between two
or more IEDs. This method is described in the IEC 61850–7–2 clause 15. The
concept is based on sending a multicast over the Ethernet. Whoever needs the
information detects the telegram by its source address and will read the telegram
and deals with it. The telegrams are multicast sent and not acknowledged by the
receiver.
