The Ied Section - ABB Relion SAM600 Communication Protocol Manual

1MRK 511 441-UEN Rev. C
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)

The IED section

The IED section describes the complete IED as it is needed for IEC 61850 communication and signal
engineering. The data type template part of an IED may be seen as part of the IED, even when
separated in its own section. The IED's ICD files include the description of the logical nodes, their
data type templates and the used or supported services. The structure of the IED section follows the
definitions made in the IEC 61850 standard.
Two basic IED types are used in system configuration.
• Station level IEDs
are located on the station level and are identified as client IEDs when they read or write
information from or to the bay IEDs. This functionality is represented by logical nodes of group
"Information (I)". These are the logical nodes (LN) = ITCI, IHMI and ITMI. Client IEDs are the

The LPHD.PhyHealth reflects the physical health of the IED. The status is set to
Alarm when there is an internal failure in the IED or Warning if any active
communication link fails.
