9.4.7 Logical Nodes
9.4.7.1 Logical Nodes Table
The PRS-7910 series relays support IEC61850 logical nodes as indicated in the following table.
Note that the actual instantiation of each logical node is determined by the product order code.
9.5 DNP3.0 Interface
9.5.1 Overview
The descriptions given here are intended to accompany this relay. The DNP3.0 protocol is not
described here; please refer to the DNP3.0 protocol standard for the details about the DNP3.0
implementation. This manual only specifies which objects, variations and qualifiers are supported
in this relay, and also specifies what data is available from this relay via DNP3.0.
The relay operates as a DNP3.0 slave and supports subset level 3 of the protocol, plus some of
the features from level 4. The DNP3.0 communication uses the Ethernet ports (electrical or optical)
at the rear side of this relay.
