IED Description
Transmit
GOOSE Control
Reference
This field represents the GOOSE control reference information that
includes the IED name, ldInst (Logical Device Instance), LN0
lnClass (Logical Node Class), and GSEControl name (GSE Control
Block Name) (e.g., SEL_787_1CFG/LLN0$GO$GooseDSet13).
Receive
GOOSE Control
Reference
This field represents the goCbRef (GOOSE Control Block
Reference) information that includes the iedName (IED name),
ldInst (Logical Device Instance), LN0 lnClass (Logical Node
Class), and cbName (GSE Control Block Name) (e.g.,
SEL_787_1CFG/LLN0$GO$GooseDSet13).
MultiCastAddr
(Multicast Address)
This hexadecimal field represents the GOOSE multicast address.
Ptag
This three-bit decimal field represents the priority tag value, where
spaces are used if the priority tag is unknown.
Vlan
This 12-bit decimal field represents the virtual LAN (Local Area
Network) value, where spaces are used if the virtual LAN is
unknown.
StNum (State
Number)

expected.
Code
This text field contains warning or error condition text when
appropriate that is abbreviated as follows:
Transmit Data
Set Reference

Receive Data Set
Reference
This field represents the datSetRef (Data Set Reference) that
includes the iedName (IED name), ldInst (Logical Device
Instance), LN0 lnClass (Logical Node Class), and datSet (Data Set
Name) (e.g., SEL_787_1CFG/LLN0$DSet13).
