List of almost all IEC 61850 Logical Nodes

A list of some 280 Logical Nodes from the following documents has been posted (see below):

  • IEC 61850-7-4 Ed2
  • IEC 61850-7-410 Ed1
  • IEC 61850-7-420 Ed1
  • IEC 61400-25-2 Ed1


Download the list of the 280 Logical Nodes [pdf; 314 KB].

You can see if the LN is new, extended (few, several, many extensions) or more or less unchanged.

You will find a lot of new LNs in IEC 61850-7-4 like the LGOS (GOOSE Subscription). The LN LGOS is defined for the monitoring of GOOSE messages:
