SEL-400 Series Relays Instruction Manual Date Code 20171006
IEC 61850 Communication
Logical Nodes
Logical nodes also include the following Beh attributes:
Beh q and Beh t per the Time Stamps and Quality subsection.
Health
The SEL-400 series relay includes at the top-level LN0 within each LD the fol-
lowing enumerations for Health stVal:
The top-level logical node of each LD also includes the following Health attri-
butes:
Health q and Health t per the Time Stamps and Quality subsection.
NamPlt
The top-level LN0 of each LD includes the following NamPlt attributes:
➤ NamPlt vendor which is set to “SEL”.
➤ NamPlt swRev which contains the relay FID string value.
➤ NamPlt d, which is the LD description.
Common Logical Nodes
Table 17.10–Table 17.13 show the logical nodes (LNs) supported in all SEL-400
series relays. See the respective product-specific instruction manuals to see
which additional logical nodes are available in that relay.
Table 17.10 shows the LNs associated with the Logical Node CFG.
Health stVal Enumeration Health stVal Value Description
1 Ok EN Relay Word bit = 1
5 Alarm EN Relay Word bit = 0
