3.4 Logical devices and logical nodes
The PM180 IEC 61850 server provides a single logical device MET1.
The PM180 IEC 61850 server provides two logical devices CTRL and MET1 described in the
following table. The domain name of a logical device can incorporate a configurable IED
name (see Section 6.2) that will precede a logical device name.
Logical device Description
CTRL Bay control elements – breaker and switch control
MET1 Metering, measurements and general digital input and output
elements
Logical devices contain logical nodes LPHD and LLN0 dedicated to the PM180 unit, and a set
of functional logical nodes for functions supported by the PM180. Logical node names are
fixed.
The following tables describe attributes of logical nodes. Not listed attributes are either
optional (O), or conditional (C) and are not supported by the PM180. Mandatory (M)
attributes are always present.
The PM180 also uses extension (E) attributes for some logical nodes.
