CHAPTER 5: SETTINGS
RxGOOSE Analog1 RxGOOSE
Range: None, RxGOOSE1, RxGOOSE2, and so on
Default: None
This setting selects the RxGOOSE containing the value that drives the RxGOOSE Analog1 FlexAnalog operand. If set to
None, the RxGOOSE Analog1 FlexAnalog operand assumes its default state.
RxGOOSE Analog1 Member
Range: 1 to 64 in steps of 1
Default: 1
This setting selects the GOOSE message member that drives the RxGOOSE Analog1 FlexAnalog operand. A setting of 1
selects the first member, 2 selects the second member, and so on. Entering a number greater than the number of
members in the message and entering the number of a member that is not a FLOAT32 results in the RxGOOSE Analog1
FlexAnalog operand assuming its default state.
RxGOOSE Analog1 DEFAULT
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 selected RxGOOSE has lost its connectivity with the
publisher and the RxGOOSE Analog1 DEFAULT MODE is set to "Default Value." Otherwise this setting has no effect. This
setting is stored as an IEEE 754 / IEC 60559 floating point number. Because of the large range of this setting, not all
possible values can be stored. Some values can be rounded to the closest possible floating point number.
RxGOOSE Analog1 DEFAULT MODE
Range: Default Value, Last Known
Default: Default Value
When the selected RxGOOSE has lost its connectivity with the publisher and this setting is "Last Known," the value of the
RxGOOSE Analog1 FlexLogic operand remains at the last received value. When the selected RxGOOSE has lost its
connectivity with the publisher and this setting value is "Default Value," then the RxGOOSE Analog1 FlexLogic operand is
defined by the RxGOOSE Analog1 DEFAULT setting. After restart, until a message is received, the operand value is the
default value.
RxGOOSE Analog1 UNITS
Range: up to 4 characters
Default:
This setting specifies a four-character string that can 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 to
configure 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 a
FlexElement. 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
Range: 0.000 to 1000000000.000 in steps of 0.001
Default: 1.000
This setting specifies the per-unit base value for other N60 features to use with the RxGOOSE Analog1 operand. A
FlexElement 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 and
its per-unit base value is not appropriate, the rescaling operation can result in unnecessary loss of precision or overflow
in the integer result. The FlexElement Base Units table in the Settings > FlexLogic > FlexElements section later, which
tabulates the per-unit base value used by its pickup setting and implies the per-unit base used by other FlexAnalogs, can
be of use in selecting a value for the RxGOOSE Analog1 PU setting.
Some UR elements have requirements for the type of input operands, for instance current type or voltage type. These
elements assume that RxGOOSE Analog operands are of whatever type is necessary to meet these requirements.
