Figure 60: 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
upper part is the visible function block in ACT and the lower part is the logical node data for the
function block.
7.1.2.1

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.
