5-52 D30 LINE DISTANCE PROTECTION SYSTEM – INSTRUCTION MANUALPRODUCT SETUP CHAPTER 5: SETTINGS5Base this setting on the TxGOOSE UPDATE TIME and the tolerable number of contiguous message delivery misses. Forexample, if the heartbeat time is 10 s, and missing up to three successive messages is tolerable, make the setting 10*3 +1 = 31 s. The extra second is to ensure that arrival of the third heartbeat transmission beats the timeAllowedtoLive timer.The standard suggests that the heartbeat time be less than (actually half) of the timeAllowedtoLive parameter.RxGOOSENavigate to Settings > Product Setup > Communications > IEC 61850 > GOOSE > RxGOOSE > RxGOOSE Messages.IEC 61850, GOOSE is an efficient method for simultaneous high-speed delivery of the same generic substation eventinformation in a publishing physical device to more than one subscribing physical device. An RxGOOSE is a UR elementimplementing a single IEC 61850 GOOSE message subscribing service. The publishing function in URs is performed byTxGOOSE elements, as described in the previous section. Each D30 has 16 RxGOOSE elements. Each RxGOOSE element cansubscribe to GOOSE messages from a specified publisher. Subscribed messages can contain up to 64 of any set of dataattributes with basic types BOOLEAN, FLOAT32, INT32, Dbpos, TimeStamp, or Quality. Messages containing data objects,that is to say structured data, are not accepted.With these conditions, GOOSE messages from any device of any manufacturer that implements the IEC 61850 edition 1.0or 2.0 GOOSE publish service can be subscribed to. The UR accepts both the variable-length encoded GOOSE messagesspecified in IEC 61850-8-1:2004 and the Fixed-Length encoded GOOSE messages as specified in IEC 61850-8-1:2011clause A.3.Each enabled RxGOOSE monitors for interruption of the GOOSE messages that it subscribes to based on the value in thetimeAllowedtoLive field of the last message received. If a new message is not received within that time interval, theRxGOOSE assumes that connectivity is lost. FlexLogic operands (for example, RxGOOSE1 On, RxGOOSE1 Off) reflect thestatus of each RxGOOSE connectivity. RxGOOSE connectivity of an RxGOOSE with non-zero MAC address is also consideredlost after the D30 finishes restart until a message is received. When RxGOOSE connectivity is lost, a common RxGOOSE Failself-test activates.Navigate to Settings > Product Setup > Communications > IEC 61850 > GOOSE > RxGOOSE > RxGOOSE Messages >RxGOOSE1 to access the settings that specify the messages to be accepted by the first RxGOOSE element. Messages thatcontain 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 is Forcible; see the Testing section at the endof this chapter for details. The settings and functionality for the other RxGOOSE are similar.Navigate to Settings > Product Setup > Communications > IEC 61850 > GOOSE > RxGOOSE > RxGOOSE Messages >RxGOOSE1. The following settings are available.Figure 5-14: IEC 61850 RxGOOSE Messages panel
