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.
