CHAPTER 5: STATUS COMMUNICATIONS
869 MOTOR PROTECTION SYSTEM – INSTRUCTION MANUAL 5–7
Communications
GOOSE Rx and Tx
The 869 supports 3 GOOSE transmissions and 8 GOOSE receptions each with 64 items per
transmission or reception. Non-structured GOOSE is supported. Each item within the
GOOSE message can be a digital or analog value. Messages are launched within one scan
of a digital point status change or an analog exceeding its deadband. The 869 supports a
t
otal of remote digital outputs.
The 869 server supports a subset of the server features described in part 7.2 of the
I
EC61850 standard.
GOOSE MESSAGING
As indicated above, the 869 supports 3 GOOSE transmissions and eight GOOSE receptions
as shown
in the table below:
* Launch speed is measured by comparing the time stamp in SOE of digital remote output
status change to the time stamp of message seen on the network by a computer who’s
clock is synchronized by an IRIG-B card to the same IRIG-B source as the 869 relay.
REMOTE INPUTS
Path:
Status > Communications > Remote Inputs
The present state of the 32 remote inputs are shown here. The state displayed is the
remote point unless the remote device has been established to be “Offline” in which case
the value shown is the programmed default state for the remote input.
GGIO1 INDICATIONS
Path:
Status > Communications > GGIO1 Indications
The present state of the 32 GGIO1 Indications are shown here. There are up to 32 GGIO
indications that can be used to map any FlexLogic operand into the IED 61850 information
model. Default value is Off.
