The D90 supports the Manufacturing Message Specification (MMS) protocol as specified
by IEC 61850. MMS is supported over the TCP/IP over Ethernet protocol stack. Polling,
unbuffered reporting, and buffered reporting are supported. Direct operate and select-
before-operate are supported.
IEC 61850 provides two fast mechanisms to exchange information between peers in a
substation. One is used for transferring status information and is called Generic Substation
Status Event (GSSE). The other includes support for a variety of information types, including
measured values. It is called the Generic Object Oriented Substation Event (GOOSE)
mechanism.
GOOSE or GSSE messages are multicast repeatedly across a substation LAN. All devices on
the LAN can receive these messages, but only those devices that require the data are
configured to act on them. Because there is no handshaking between devices, GOOSE and
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 are not usually
forwarded by network routers. GOOSE messages can be forwarded by routers if the router
has been configured for VLAN functionality.

The following setting is available.
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
