Organization of LDs, LNs, DOs and DAs in an IED
•
A server represents the communication interface to the subnetwork (Ethernet).
•
One or more logical device(s) (LD) are connected to a server.
•
A set of logical nodes belong to a LD.
•
The LN LLN0 is a special logical node per LD and contains for example the data sets,
the various control blocks, inputs (from GOOSE messages). In IED 650 series, the
data sets and the control blocks shall be located to LD0.
•
The LN LPHD is a special logical node per LD and contains data objects that describe
the status of the physical device (the IED)
•
Each logical node represents a function and contains a number of data objects (DO)
•
Each DO includes a number of data attributes (DA)
The data objects represent information signals that may be routed to station level IEDs or
to other bay IEDs that are communicating via GOOSE. The signal engineering task is to
