ANALOG 1 VALUE
— This setting selects the FlexAnalog parameter used to drive the associated direct analog output.
ANALOG 1 DEADBAND
— This setting specifies the deadband value used to trigger transmission of the associated direct
analog output. This value is stored as an IEEE 754 / IEC 60559 floating-point number. Because of the large range for this
setting, not all values can be stored—some values can be rounded to the closest possible floating point number.
ANALOG 1 TRIGGER
— This setting selects the FlexLogic operand used to trigger the transmission of the associated direct
analog output. Transmission occurs on the rising edge of the operand. The operand must transition from 0 to 1 and remain
at a value of 1 for at least one power system cycle to ensure detection of the rising edge and transmission of the
associated direct analog output.

INPUTS/OUTPUTS
DIRECT ANALOGS
DIRECT ANALOG INPUTS
DIRECT ANALOG 1(32) INPUT
The direct analogs feature allows the transmission of analog values between any two UR-series relays supporting the
feature. The communication channel is the same as that used for the direct inputs and outputs feature. When the direct
inputs/outputs and direct analog features are used together on the same channel, the UR-series relays must be using
firmware version 5.20 or higher.
The settings for direct analog input 1 are as follows. The description applies to all 32 direct analog inputs.
DIRECT ANALOG 1 DEVICE ID
— This value selects the source of the direct analog 1 input. Direct analog input 1 is driven by
the device programmed in this setting.
DIRECT ANALOG 1 NUMBER
— This value specifies which input to extract the value for the direct analog 1 input. Direct analog
input 1 is driven by the input programmed in this setting. This setting value corresponds to the direct analog output
number of the sending device.
DIRECT ANALOG 1 DEFAULT
— This setting specifies the value of direct analog input 1 when the associated direct device is
offline and the
DIRECT ANALOG 1 DEFAULT MODE
is set to “Default Value.” When the associated direct device is offline and
the default mode is set to “Last Known,” the value of direct analog input 1 remains at the last received value. This value is
stored as an IEEE 754 / IEC 60559 floating-point number. Because of the large range for this setting, not all values can be
stored—some values can be rounded to the closest possible floating point number.
DIRECT ANALOG 1 UNITS
— This setting provides a four-character string that is used in the direct analog input 1 actual
values display.
DIRECT ANALOG 1 PU
— This setting defines the per-unit base factor when using the
DIRECT ANALOG INPUT 1 ACTUAL
FlexAnalog value in other N60 features, such as FlexElements. This value is used to normalize the direct analog input 1
FlexAnalog quantity to its per-unit base. See the FlexElements section for additional details on per-unit base values.
5.9.7.4 Application example
Direct analog input FlexAnalog parameters (the
DIR ANALOG INPUT 1
to
DIR ANALOG INPUT 32
values) are available for use in
other N60 functions that use FlexAnalog parameters.
