Remote double-point status inputs
110
Default State
Range: On, Off, Latest/On, Latest/Off
Default: Off
This 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.
– The "On" value defaults the input to logic 1.
– The "Off" value defaults the input to logic 0.
– The "Latest/On" value 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.
– The "Latest/Off" value 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.
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 are extracted from GOOSE messages originating in the
Plus
remote device. The D90
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" will accept double-point status
information that will be decoded by the remote double-point status inputs configured to
this dataset item.
