5.8 INPUTS AND OUTPUTS

PATH: SETTINGS INPUTS/OUTPUTS
 REMOTE INPUT 1

Remote Inputs that create FlexLogic operands at the receiving relay are extracted from GSSE/GOOSE messages originat-
ing in remote devices. Each remote input can be selected from a list consisting of: DNA-1 through DNA-32, UserSt-1
through UserSt-32, and Dataset Item 1 through Dataset Item 32. The function of DNA inputs is defined in the IEC 61850
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.

GSSE/GOOSE message required.
The
REMOTE IN 1 DEFAULT STATE
the remote device sending the point is declared to be non-communicating. The following choices are available:
• Setting
REMOTE IN 1 DEFAULT STATE
• Setting
REMOTE IN 1 DEFAULT STATE
• Setting
REMOTE IN 1 DEFAULT STATE
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
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.
