1–64 345 TRANSFORMER PROTECTION SYSTEM – COMMUNICATIONS GUIDE
ETHERNET INTERFACE CHAPTER 1: COMMUNICATIONS GUIDE
GOOSE transmission The 345 firmware supports one transmission dataset.
All elements in the transmit dataset must be Booleans values.
The user can define the number of items in the transmit data setup, to a maximum of 32.
The minimum number of items in a data set is 1.
The number of data items configured before the NULL (below), determines the dataset
length. It is also possible to map any Item to a fixed value (ON or OFF).
For GOOSE transmission the firmware allows users to assign, (through EnerVista SR3
Setup Software) an DataSetReference composed as follows:
1. IEDNameLDInst/LLN0$
2. the string (default: GOOSE1) contained in the Modbus address:
The IEDName is taken from setting S1 Relay Setup > Installation > Relay Name
Setting the IEDName to "Feeder_25Kv_Line1" (for example) would result in a DataSet
Reference:
Feeder_25Kv_Line1LDInts/LLN0$GOOSE1
Another, less common, possibility is to change the 123E setting ( using modbus ) for
example to "GOOSE_Points" resulting in a DataSet Reference:
Feeder_25Kv_Line1LDInts/LLN0$GOOSE_Points
