5-56 C70 CAPACITOR BANK PROTECTION AND CONTROL SYSTEM – INSTRUCTION MANUALPRODUCT SETUP CHAPTER 5: SETTINGS5TxGOOSE1 VLAN IDRange: 0 to 4095 in steps of 1Default: 0The value entered sets the VID value in the IEEE 802.1Q VLAN tag included in published TxGOOSE1 messages. VID can beused by network devices to direct messages to only selected devices, reducing network burden. VID values of 0 and 1are assigned by IEEE 802.1Q to other functions and are not to be used for GOOSE.TxGOOSE1 ETYPE APPIDRange: 0 to 65535 in steps of 1Default: 0The value entered sets the APPID value in published GOOSE messages and can be used by subscribers to discriminateTxGOOSE1 messages from other GOOSE messages.The standard reserves the value range 0 to 16383 for GOOSE Type 1 (Fast messages), and reserves the value range32768 to 41151 for GOOSE Type 1A (Trip messages). Some subscribers can process messages in the Type 1A rangefaster than messages in the Type 1 range. The standard reserves the default value (0) to indicate lack of configuration.The standard strongly recommends unique, source-orientated APPIDs within a given system.TxGOOSE1 CONFREVRange: 0 to 4294967295 in steps of 1Default: 1The entered value sets the confRev value in published GOOSE messages and can be used by subscribers to discriminateTxGOOSE messages of the expected configuration revision from messages of a different revision. The standard requiresthat CONFREV be incremented each time the members or the order of the members published is changed. The standardstates that the value of 0 is reserved.TxGOOSE1 RETRANS TIMERange: 0 to 100 ms in steps of 1 msDefault: 4 msIf the entered time is non-zero, when a member value change is detected, four event transmissions are sent, thenheartbeat transmissions resume. The interval between the first and second event transmissions, and between thesecond and third, is the time set here. The interval between the third and the fourth event transmission is double the settime. If the entered time is zero, only a single event transmission occurs, then heartbeat transmissions resume.TxGOOSE1 TIME TO LIVERange: 1 to 300 s in steps of 1 sDefault: 300 sThe value entered sets the timeAllowedtoLive value in published TxGOOSE1 messages. The standard requiressubscribers to assume a failure has occurred when another TxGOOSE1 message is not received within the publishedtimeAllowedtoLive time.Base 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 setting10 * 3 + 1 = 31 s. The extra second is to ensure that arrival of the third heartbeat transmission beats thetimeAllowedtoLive timer.TxGOOSE1 UPDATE TIMERange: 1 to 60 s in steps of 1 sDefault: 60 sThis setting specifies the time interval between heartbeat messages, meaning messages that are sent periodically whileno events are detected.
