CHAPTER 5: SETTINGS
— This setting selects the FlexAnalog parameter used to drive the associated direct analog output.
ANALOG 1 VALUE
— This setting specifies the deadband value used to trigger transmission of the associated direct
ANALOG 1 DEADBAND
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.
— This setting selects the FlexLogic operand used to trigger the transmission of the associated direct
ANALOG 1 TRIGGER
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.

 DIRECT ANALOG 1
 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.
— This value selects the source of the direct analog 1 input. Direct analog input 1 is driven by
DIRECT ANALOG 1 DEVICE ID
the device programmed in this setting.
— This value specifies which input to extract the value for the direct analog 1 input. Direct analog
DIRECT ANALOG 1 NUMBER
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.
— This setting specifies the value of direct analog input 1 when the associated direct device is
DIRECT ANALOG 1 DEFAULT
offline and the
DIRECT ANALOG 1 DEFAULT MODE
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.
— This setting provides a four-character string that is used in the direct analog input 1 actual
DIRECT ANALOG 1 UNITS
values display.
— This setting defines the per-unit base factor when using the
DIRECT ANALOG 1 PU
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.
