PRODUCT SETUP
R-TxGOOSE1 IP CLASS
Range: 0 to 256 in steps of 1
Default: 46
When the TxGOOSE1 MODE setting is other than R-GOOSE, the value of this setting is not used. Otherwise this setting
selects the IPv4 Differentiated Services Code Point-DSCP (formerly called TypeOfService-TOS) value. This value provides
priority routing, when supported in the routers. The default value is for Expedited Forwarding (101110B, 46 or 2EH).
R-TxGOOSE1 DST IP
Range: 0.0.0.0 to 255.255.255 in steps of 1
Default: 224.0.0.0
When the TxGOOSE1 MODE setting is other than R-GOOSE, the value of this setting is not used. Otherwise this setting
specifies destination IP address for the R-TXGOOSE1 that is entered in Standard IPV4 address format. The destination IP
address needs to be a valid multicast or unicast IP address. The value specified in this setting is mapped to IPv4 header
32 bit field for Destination IP Address while publishing R-GOOSE1.
The default IP address 224.0.0.0 is reserved, and hence not a valid multicast IP address.
The source IP address is that of the UR port from which the R-GOOSE messages are transmitted.
R-TxGOOSE1 SECURITY
Range: None, Signature, SignatureAndEncryption
Default: None
This setting specifies level of security (authentication/encryption) used for TxGOOSE1. None specifies no security
mechanisms are to be used. Signature specifies only signature (no encryption) is to be used. SignatureAndEncryption
specifies that both signature and encryption are to be used.

IEC 61850, GOOSE is an efficient method for simultaneous high-speed delivery of the same generic substation event
information by a publishing device to more than one subscribing device. An RxGOOSE is a UR element implementing a
single IEC 61850 GOOSE message subscribing service. The publishing function in URs is performed by TxGOOSE elements,
as described in the previous section.
Each UR with the IEC 61850 order code option has 64 RxGOOSE elements. Each RxGOOSE element can subscribe to GOOSE
messages from a specified publisher. Each RxGOOSE can either use the original format specified in IEC 61850 8 1:2011 or
the routable GOOSE (R-GOOSE) format specified in IEC TR 61850-90-5:2012. Subscribed message members can be
DataObjects, SubDataObjects, DataAttributes or SubAttributes. In E2-2.0 mode members are restricted to basic types
BOOLEAN, FLOAT32, INT32, Dbpos, TimeStamp or Quality. Each subscribed message can contain up to 64 values. A
member can be a structure containing several values; note that it is the number of values rather than the number of
members that are limited to 64.
GOOSE messages from any device of any manufacturer that implements the IEC 61850 edition 1.0 or 2.0 GOOSE publish
service or the 61850-90-5 R GOOSE service can be subscribed to. The UR accepts both the variable length encoded GOOSE
messages specified IEC 61850 8 1:2004 and the Fixed-Length encoded GOOSE messages as specified in IEC 61850 8
1:2011 clause A.3.
Each enabled RxGOOSE monitors for interruption of the GOOSE messages it subscribes to based on the value in the
timeAllowedtoLive field of the last message received. If a new message is not received within that time interval, the
RxGOOSE assumes that connectivity is lost. FlexLogic operands (for example RxGOOSE1 On, RxGOOSE1 Off) reflect the
status of each RxGOOSE connectivity. An RxGOOSE connection is also considered lost after the UR finishes restart until a
message is received. While any RxGOOSE connectivity is lost, a common RxGOOSE Fail self-test is activated.
Messages that contain the value true in the ndsCom field are never accepted. Messages that contain the value true in the
simulation field (test field in edition 1.0 messages) are accepted only when the UR Test Mode Function setting is set to
Forcible or Isolated.
RxGOOSE messages can be received through any UR Ethernet port.
