The
REMOTE IN 1 DEFAULT STATE
setting selects the logic state for this point if the local relay has just completed startup or
the remote device sending the point is declared to be non-communicating. The following choices are available:
• Setting
REMOTE IN 1 DEFAULT STATE
to “On” value defaults the input to logic 1.
• Setting
REMOTE IN 1 DEFAULT STATE
to “Off” value defaults the input to logic 0.
• Setting
REMOTE IN 1 DEFAULT STATE
to “Latest/On” freezes the input in case of lost communications. If the latest state is
not known, such as after relay power-up but before the first communication exchange, the input will default to logic 1.
When communication resumes, the input becomes fully operational.
• Setting
REMOTE IN 1 DEFAULT STATE
to “Latest/Off” freezes the input in case of lost communications. If the latest state is
not known, such as after relay power-up but before the first communication exchange, the input will default to logic 0.
When communication resumes, the input becomes fully operational.

REMOTE DPS INPUT 1(5)
Remote double-point status inputs are extracted from GOOSE messages originating in the remote device. Each remote
double point status input must be programmed to replicate the logic state of a specific signal from a specific remote device
for local use. This functionality is accomplished with the five remote double-point status input settings.
• REM DPS IN 1 ID : This setting assigns descriptive text to the remote double-point status input.
• REM DPS IN 1 DEV : This setting selects a remote device ID to indicate the origin of a GOOSE message. The range is
selected from the remote device IDs specified in the Remote devices section.
• REM DPS IN 1 ITEM : This setting specifies the required bits of the GOOSE message.
The configurable GOOSE dataset items must be changed to accept a double-point status item from a GOOSE dataset
(changes are made in the

items configured to receive any of “GGIO3.ST.IndPos1.stV” to “GGIO3.ST.IndPos5.stV” will accept double-point status
information that will be decoded by the remote double-point status inputs configured to this dataset item.
The remote double point status is recovered from the received IEC 61850 dataset and is available as through the
