GOOSE Analogs that represent current, voltage, power, frequency, angles, or power factor can be used in a FlexEle-
ment. The following text must be used in the UNITS setting, to represent these types of analogs: A, V, W, var, VA, Hz,
deg, and no text (blank setting) for power factor.
GOOSE Analogs can be compared to other GOOSE Analogs with any character string or no string.
• GOOSE ANALOG 1 PU: This setting specifies the per-unit base factor when using the GOOSE analog input FlexAna-
log values in other T35 features, such as FlexElements. The base factor is applied to the GOOSE analog input FlexAn-
alog quantity to normalize it to a per-unit quantity. The base units are described in the following table.
The per-unit base setting represents thousands, not single units. For example, a PU base of 1.000 is actually 1000 and
a PU base of 0.001 is 1.
When using GOOSE Analogs and PU base in FlexElements, the largest value that can be displayed in the FlexEle-
ment actual values is 2,140,000.000.
The GOOSE analog input FlexAnalog values are available for use in other T35 functions that use FlexAnalog values.

The IEC 61850 GOOSE uinteger inputs feature allows the transmission of FlexInteger values between any two UR-series
devices. The following settings are available for each GOOSE uinteger input.
• UINTEGER 1 DEFAULT: This setting specifies the value of the GOOSE uinteger input when the sending device is
offline and the UINTEGER 1 DEFAULT MODE is set to “Default Value”.This setting is stored as a 32-bit unsigned integer
number.
• UINTEGER 1 DEFAULT MODE: When the sending device is offline and this setting is “Last Known”, the value of the
GOOSE uinteger 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 uinteger input is defined by the
UINTEGER 1 DEFAULT setting.
