b) DIRECT MESSAGES
Direct messages are used only between L30 relays connected directly using type 7 or type 2 digital communication cards.
These messages are transmitted every one-half of the power frequency cycle (10 ms for 50 Hz and 8.33 ms for 60 Hz) This
facility is of particular value for pilot schemes and transfer tripping. Direct messaging is available on both single channel
and dual channel communications modules. The inputs and outputs on communications channel 1 are numbered 1-1
through 1-8, and the inputs and outputs on communications channel 2 are numbered 2-1 through 2-8.
Settings associated with direct messages are automatically presented in accordance with the number of
channels provided in the communications module in a specific relay.

c) LOCAL DEVICES: DEVICE ID FOR TRANSMITTING GSSE MESSAGES
In a L30 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

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 devices are available for setting purposes. A receiving relay must be programmed 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.

Note that the dataset for the received data items must be made up of existing items in an existing logical node. For this rea-
son, logical node GGIO3 is instantiated to hold the incoming data items. GGIO3 is not necessary to make use of the
received data. The remote input data item mapping takes care of the mapping of the inputs to remote input FlexLogic oper-
ands. However, GGIO3 data can be read by IEC 61850 clients.
