The RxGOOSE MODE, RxGOOSE Dst MAC, RxGOOSE GoCBRef, ConfRev, and RxGOOSE Member settings must be correctly
entered for GOOSE messages to be accepted. The RxGOOSE MODE setting enables the UR to receive GOOSE rather than R-
GOOSE messages. Dst MAC is used by the UR hardware to pass only subscribed messages, so the CPU does not parse
messages of no interest to that device. GoCBRef is used to determine which if any of the RxGOOSE an incoming message is
for. ConfRev is used to verify that the publisher has the expected configuration revision. And the Member settings define
the structure of the data in the message, so that appropriate buffers can be pre-allocated. In EnerVista UR Setup, the
structure must consist of the basic data types BOOLEAN, FLOAT32, INT32, Dbpos, Quality, and TimeStamp; that is to say,
EnerVista UR Setup cannot manually configure reception of structured GOOSE messages that are used to communicate
FCDs. However, messages with structure can be used by importing into UR Setup SCL files wherein the message structure
is already defined.
When RxGOOOSE MODE is set to R-GOOSE, the R-RxGOOSE DST IP needs to be a valid multicast or unicast IP address. R-
RxGOOSE RECEPTION MODE specifies the R-RxGOOSE DST IP range. When RxGOOSE RECEPTION MODE is set to SSM, R-
RxGOOSE DST IP must be in the range of 232.0.0.1 to 232.255.255.255. When RxGOOSE RECEPTION MODE is set to ASM, R-
RxGOOSE DST IP must be in the range of 224.0.0.1 to 239.255.255.255, excluding the SSM range. Note that the SSM range
is inside the ASM range and therefore the ASM use excludes the SSM range. The default destination IP address 224.0.0.0 is
reserved, and hence not a valid multicast IP address.
With R-GOOSE subscription, a UR can subscribe to a maximum of 25 unique destination IP addresses.
Each of the remaining settings on this page can be left at its default value, in which case the value in the corresponding
field of incoming messages is not validated, the message is accepted no matter the received field value.
For a value received in a subscribed GOOSE to be used by the UR, it must be mapped to a FlexLogic or FlexAnalog operand.
This is done by RxGOOSE Input elements, of which there are three types: an RxGOOSE Boolean Input maps a BOOLEAN
Member to a FlexLogic "On" operand; an RxGOOSE DPS Input maps a Dbpos (double point position) Member to "Bad,"
"Interm," "On," and "Off" FlexLogic operands; and an RxGOOSE Analog Input maps a FLOAT32 Member to an Analog In
FlexAnalog operand. These operands can be used as inputs wherever a FlexLogic or FlexAnalog operand can be used.
3.1.6 Reports
A report is an IEC 61850 service whereby a client IED can establish a one-to-one connection over a local area network to a
server, and over this connection the server keeps the client updated on the values of a set of the server's signals. The set of
signals reported on is defined by a dataset, with datasets being explained earlier in this chapter. Report messages can be
configured to be issued periodically, on request, and/or on events, where an event is defined as one of the signals
