Remote Inputs - GE G30 Instruction Manual

5 SETTINGS
Receiving devices are constantly monitoring the communications network for messages they require, as recognized by the
identification of the originating device carried in the message. Messages received from remote devices include the mes-
sage time allowed to live. The receiving relay sets a timer assigned to the originating device to this time interval, and if it
has not received another message from this device at time-out, the remote device is declared to be non-communicating, so
it will use the programmed default state for all points from that specific remote device. If a message is received from a
remote device before the time allowed to live expires, all points for that device are updated to the states contained in the
message and the hold timer is restarted. The status of a remote device, where "Offline" indicates non-communicating, can
be displayed.
The remote input/output facility provides for 32 remote inputs and 64 remote outputs.
b) LOCAL DEVICES: ID OF DEVICE FOR TRANSMITTING GSSE MESSAGES
In a G30 relay, the device ID that represents the IEC 61850 GOOSE application ID (GoID) name string sent as part of each
GOOSE message is programmed in the
GSSE/GOOSE CONFIGURATION
Likewise, the device ID that represents the IEC 61850 GSSE application ID name string sent as part of each GSSE mes-
sage is programmed in the

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.
The setting allows the user to assign descriptive text to the remote input. The
REMOTE INPUT 1 ID
selects the remote device which originates the required signal, as previously assigned to the remote device via the setting
(see the Remote devices section). The

the remote device sending the point is declared to be non-communicating. The following choices are available:
• Setting
