Range: –1000000.000 to 1000000.000 in steps of 0.001
Default: 1000.000
This setting specifies the value of the GOOSE analog input when the sending device is
offline and the
Default Mode
IEEE 754 / IEC 60559 floating point number. Because of the large range of this setting,
not all possible values can be stored. Some values may be rounded to the closest
possible floating point number.
Mode
Range: Default Value, Last Known
Default: Default Value
When the sending device is offline and this setting is "Last Known", the value of the
GOOSE analog input remains at the last received value. When the sending device is
