– Off — Defaults the input to logic 0
– 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 defaults to logic 1. When communication resumes, the input
becomes fully operational.
– 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 defaults to logic 0. When communication resumes, the input
becomes fully operational.
Events
Range: Enabled, Disabled
Default: Disabled
This setting enables and disables the logging of remote input events in the sequence of
events recorder.
Remote double-point status inputs
Remote double-point status inputs are extracted from GOOSE messages originating in the
remote device. The D90
Plus
provides 16 remote double-point status inputs. 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.
The configurable GOOSE dataset items must be changed to accept a double-point status
item from a GOOSE dataset. Dataset items configured to receive any of
“GGIO3.ST.IndPos1.stV” to “GGIO3.ST.IndPos16.stV” accept double-point status information
that is decoded by the remote double-point status inputs configured to this dataset item.
Select the Settings > Communications > IEC 61850 > GSSE/GOOSE Configuration >
Inputs/Outputs > Remote DPS Inputs menu to open the remote double-point status
inputs configuration window.
