3.1.5 RxGOOSE
The IEC 61850 standard does not contain a control block or equivalent for subscribing to GOOSE messages. The standard
assumes that the subscriber has access to a description of the information model of the publisher, and from that can
extract the information that it needs to subscribe.
Since UR 7.30, an RxGOOSE is a UR element that contains in a single entity all the information necessary to subscribe to a
specific GOOSE message. Both the UR and EnerVista UR Setup software automatically extract this information on receiving
an appropriate SCL file. However, EnerVista UR Setup also allows manual entry of this information via RxGOOSE
configuration pages. The figure shows an example of an RxGOOSE configuration page, which subscribes to the message
generated by the TxGOOSE and dataset examples of the preceding sections of this manual.
Figure 3-6: IEC 61850 RxGOOSE Messages panel
The RxGOOSE Dst MAC, RxGOOSE GoCBRef, and RxGOOSE Member settings must be correctly entered for GOOSE
messages to be accepted. 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. 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 configure structured GOOSE messages that are
used to communicate FCDs.
