C.7LOGICAL NODES C.7.1 LOGICAL NODES TABLE
The UR-series of relays supports IEC 61850 logical nodes as indicated in the following table. Note that the actual instantia-
tion of each logical node is determined by the product order code. For example. the logical node “PDIS” (distance protec-
tion) is available only in the D60 Line Distance Relay.
