Therefore, at each terminal, directinputs 5 and 6 should be ANDed in FlexLogic™ and the resulting operand configured as the permission to trip (HYB POTTRX1 setting).5.7.11 IEC 61850 GOOSE ANALOGSPATH: SETTINGS INPUTS/OUTPUTS IEC 61850 GOOSE ANALOGS GOOSE ANALOG INPUT 1(16)The IEC 61850 GOOSE analog inputs feature allows the transmission of analog values between any two UR-seriesdevices. The following settings are available for each GOOSE analog input.• ANALOG 1 DEFAULT: This setting specifies the value of the GOOSE analog input when the sending device is offlineand the ANALOG 1 DEFAULT MODE is set to “Default Value”.This setting is stored as an IEEE 754 / IEC 60559 floatingpoint number. Because of the large range of this setting, not all possible values can be stored. Some values may berounded to the closest possible floating point number.• ANALOG 1 DEFAULT MODE: When the sending device is offline and this setting is “Last Known”, the value of theGOOSE 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 ANALOG 1 DEFAULT setting.• GOOSE ANALOG 1 UNITS: This setting specifies a four-character alphanumeric string that can is used in the actualvalues display of the corresponding GOOSE analog input value.GOOSE Analogs are floating-point values, with no units. The GOOSE UNIT and PU base settings allow the user toconfigure GOOSE Analog, so that it can be used in a FlexElement.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.
