specification and is presented in the IEC 61850 DNA Assignments table in the Remote Outputs section. The function of
UserSt inputs is defined by the user selection of the FlexLogic operand whose state is represented in the GSSE/GOOSE
message. A user must program a DNA point from the appropriate FlexLogic operand.
Remote input 1 must be programmed to replicate the logic state of a specific signal from a specific remote device for local
use. This programming is performed via the three settings shown above.
The REMOTE INPUT 1 ID setting allows the user to assign descriptive text to the remote input. The REMOTE IN 1 DEVICE setting
selects the remote device which originates the required signal, as previously assigned to the remote device via the setting
REMOTE DEVICE (16) ID (see the Remote Devices section). The REMOTE IN 1 ITEM setting selects the specific bits of the
GSSE/GOOSE message required.
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.
For additional information on GSSE/GOOOSE messaging, see the Remote Devices section in this chapter.
5.8.7 REMOTE DOUBLE-POINT STATUS INPUTS
PATH: SETTINGS INPUTS/OUTPUTS REMOTE DPS INPUTS 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
SETTINGS COMMUNICATION IEC 61850 PROTOCOL GSSE/GOOSE CONFIGURATION
RECEPTION CONFIGURABLE GOOSE CONFIGURABLE GOOSE 1(16) CONFIG GSE 1 DATASET ITEMS menus). Dataset
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
RemDPS
Ip 1 BAD
, RemDPS Ip 1 INTERM, RemDPS Ip 1 OFF, and RemDPS Ip 1 ON FlexLogic operands. These operands can then be
used in breaker or disconnect control schemes.
