IEC 61850 server configuration

114
The following settings are available for each of the IEC 61850 GOOSE analog inputs.
Default Value
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
offline and this setting value is "Default Value", then the value of the GOOSE analog input
is defined by the
Default Value
Units
Range: up to 4 alphanumeric characters
Default: ---
This setting specifies a four-character alphanumeric string that can is used in the actual
values display of the corresponding GOOSE analog input value.
PU Base
Range: 0 to 1000000000 in steps of 1
Default: 1
This setting specifies the per-unit base factor when using the GOOSE analog input
FlexAnalog™ values in other D90
base factor is applied to the GOOSE analog input FlexAnalog quantity to normalize it to a
per-unit quantity. The base units are described in the following table.
