5.7 INPUTS/OUTPUTS
Signal flow between the three IEDs is shown in the figure below:
UR IED 1
Figure 5–69: SIGNAL FLOW FOR DIRECT INPUT AND OUTPUT – EXAMPLE 3
In three-terminal applications, both the remote terminals must grant permission to trip. Therefore, at each terminal, direct
inputs 5 and 6 should be ANDed in FlexLogic and the resulting operand configured as the permission to trip (
setting).

 GOOSE ANALOG
 INPUT 1
The IEC 61850 GOOSE analog inputs feature allows the transmission of analog values between any two UR-series
devices. 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 offline
and the
ANALOG 1 DEFAULT MODE
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.
ANALOG 1 DEFAULT MODE: 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
GOOSE ANALOG 1 UNITS: This setting specifies a four-character alphanumeric string that can is used in the actual
values display of the corresponding GOOSE analog input value.
GOOSE ANALOG 1 PU: This setting specifies the per-unit base factor when using the GOOSE analog input FlexAna-
log values in other B90 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.
