IEC 61850 COMMUNICATIONS
NOTE:
General transmission configuration
GSSE transmission configuration
112
GSSE messages can transfer changes very rapidly, making them suitable for performing
interlocking and other time-critical substation functions. The IEC 61850 server supports
both GOOSE and GSSE protocols in publisher and subscriber roles. In dual-IP redundant
configurations, the IED transmits and listens on both ports simultaneously.
Since GSSE/GOOSE messages are multicast Ethernet by specification, they will not usually
be forwarded by network routers. However, GOOSE messages may be forwarded by
routers if the router has been configured for VLAN functionality.

configuration window.
Figure 90: General transmission configuration settings
The following setting is available for GSSE/GOOSE general transmission configuration.
Default GSSE/GOOSE Update Time
Range: 1 to 60 seconds
Default: 60 seconds
This setting specifies the time between GSSE or GOOSE messages when there are no
remote output state changes to be sent. When remote output data changes, GSSE or
GOOSE messages are sent immediately. This setting controls the steady-state heartbeat
time interval.
This setting is applicable to GSSE, fixed D90
