5-78 B30 BUS DIFFERENTIAL SYSTEM – INSTRUCTION MANUALPRODUCT SETUP CHAPTER 5: SETTINGS5RxGOOSE Analog1 IDRange: 0 to 20 charactersDefault: RxG Analog1This setting allows the user to assign descriptive text to RxGOOSE Analog1. Unlike RxGOOSE Booleans and RxGOOSEDPS, the RxGOOSE Analog operands have fixed names, for example RxGOOSE Analog1.RxGOOSE Analog1 RxGOOSERange: None, RxGOOSE1, RxGOOSE2, and so onDefault: NoneThis setting selects the GOOSE message that drives the RxGOOSE Analog1 FlexAnalog operand. If set to None, theRxGOOSE Analog1 FlexAnalog operand assumes its default state.RxGOOSE Analog1 MemberRange: 1 to 64 in steps of 1Default: 1This setting selects the GOOSE message member that drives the RxGOOSE Analog1 FlexAnalog operand. A setting of 1selects the first member, 2 selects the second member, and so on. Entering a number greater than the number ofmembers in the message and entering the number of a member that does not contain a FLOAT32 results in theRxGOOSE Analog1 FlexAnalog operand assuming its default state. The Subscribed to column identifies the particularFLOAT32 subscribed to even if the member is a structure containing more than one FLOAT32.RxGOOSE Analog1 DEFAULTRange: -1000000.000 to 1000000.000 in steps of 0.001Default: 1000.000This setting specifies the value of the GOOSE analog input when the selected RxGOOSE has lost its connectivity with thepublisher and the RxGOOSE Analog1 DEFAULT MODE is set to "Default Value." Otherwise this setting has no effect. Thissetting is stored as an IEEE 754 / IEC 60559 floating point number. Because of the large range of this setting, not allpossible values can be stored. Some values can be rounded to the closest possible floating point number.RxGOOSE Analog1 DEFAULT MODERange: Default Value, Last KnownDefault: Default ValueWhen the selected RxGOOSE has lost its connectivity with the publisher and this setting is "Last Known," the value of theRxGOOSE Analog1 FlexLogic operand remains at the last received value. When the selected RxGOOSE has lost itsconnectivity with the publisher and this setting value is "Default Value," then the RxGOOSE Analog1 FlexLogic operand isdefined by the RxGOOSE Analog1 DEFAULT setting. After restart, until a message is received, the operand value is thedefault value.RxGOOSE Analog1 UNITSRange: up to 4 charactersDefault: empty stringThis setting specifies a four-character string that is used in the actual values display of RxGOOSE Analog1.RxGOOSE Analogs are floating-point values, with no units. The RxGOOSE UNIT and PU base settings allow the user toconfigure RxGOOSE Analog, so that it can be used in a FlexElement.RxGOOSE Analogs that represent current, voltage, power, frequency, angles, or power factor can be used in aFlexElement. 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.RxGOOSE Analogs can be compared to other RxGOOSE Analogs with any character string or no string.RxGOOSE Analog1 PU Base in kiloRange: 0.000 to 1000000000.000 in steps of 0.001Default: 1.000This setting specifies the per-unit base value for other B30 features to use with the RxGOOSE Analog1 operand. AFlexElement for instance subtracts two quantities after converting their values to integers rescaled to a common base,the common base being the largest of the base values of the two quantities. If one of quantities is RxGOOSE Analog1 andits per-unit base value is not appropriate, the rescaling operation can result in unnecessary loss of precision or overflow
