Figure 60: IEC 61850: communication interface principle
IEC 61850 provides a method for identifying all signals that belong to a function.
These signals are identified through the logical nodes representing the functions. All
signal information for commands and monitoring are available in logical nodes.
Whenever a function block is instantiated in the Application Configuration tool,
PCM600 automatically generates the corresponding logical node data.

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, reads the telegram and handles
it. The telegrams are multicast sent and not acknowledged by the receiver.
