The data modelling uses the concept of logical nodes to identify the published information for
communication. The standard defines a set of logical nodes, each representing a communication
view of a process function with a number of data objects. For example, a transformer differential - or
line differential protection, because the standard defines only a differential protection. Therefore, it is
possible to adapt the logical node, which is defined in the standard, as a logical node class. The
standard defines methods to describe the actually used logical node as a logical node type which is
then based upon the logical node class. This allows all partners to interpret the logical node type
information because the description is completely given in the standard. The type description of all
logical nodes is part of the Data Type Template (DTT) section in the SCL description file of a station
or the IED.
Besides the information about the configuration of the communication facilities, this manual contains
the full description of all logical nodes available in the IEDs. The information about the logical nodes
and their data objects may be used to identify which signals are available for the functions as
described in the technical manual. The link to the technical manual is done in the logical node tables
by listing the signal name as given in the function block, or as seen in PCM600 or the LHMI.
