Sixteen remote devices, numbered from 1 to 16, can be selected for setting purposes. A receiving relay must be pro-
grammed to capture messages from only those originating remote devices of interest. This setting is used to select specific
remote devices by entering (bottom row) the exact identification (ID) assigned to those devices.

MESSAGE
Remote Inputs which create FlexLogic™ operands at the receiving relay, are extracted from GSSE messages originating in
remote devices. The relay provides 32 remote inputs, each of which can be selected from a list consisting of 64 selections:
DNA-1 through DNA-32 and UserSt-1 through UserSt-32. The function of DNA inputs is defined in the IEC 61850 specifica-
tion 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 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 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 the GSSE specification, refer to the Remote Devices section in this chapter.
