The conformance documents are unique for each product release and refer to each
other; the identities included in the related documents refer to a specific version of the
IED.
The communication profile in IEC 61850 uses the MMS standard, which uses
Ethernet and TCP/IP to handle the information transport within the substation.
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. The standard cannot cover all possible information that is given, for example,
by a protection function of vendor A or vendor B or for the variants of a protection
function given by the process part which is protected. 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 IED. 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.
