ABB IEC 61850 Edition 2 - The IED section

3.2 The communication section
SEMOD129771-4 v3
The or
ganization of the physical
IEDs to the communication network is
independent of the substation structure. The IEC 61850 standard defines the
communication network with no relation to an existing media or protocol. The
mapping to an existing media and protocol is specified in IEC 61850–8–1.
The IEC 61850 standard describes in part 7–2 the ACSI in a media and protocol
independent form. Part 8–1 specifies the mapping of this ACSI to the existing
MMS.
The communication section describes how information is routed between the IEDs
and contains the following parts:
• Subnetworks
• IEDs connected to different subnetworks
• Access points per IED to subnetworks
• Address
• IP address of LAN network (is exceptionally part of the address elements)
• Link to GoCB message in transmission direction (extended during signal
engineering and routing)
