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
Figure 60 this is shown by two 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.
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
