Figure 109: 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 relay parameters, settings, control and monitoring are available
in logical nodes.
Whenever a function block is instantiated in Application Configuration, PCM600
automatically generates the corresponding logical node data.
7.2.1.1 GOOSE data exchange
The IEC 61850 protocol supports a method to directly exchange data between two or
more devices (IEDs). This method is described in the IEC 61850-7-2 clause 15.
