5.8 INPUTS AND OUTPUTS
The direct analog outputs share the direct input and output settings for device ID, data rate, ring configuration, and channel
crossover.
• 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 may 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.

The direct analogs feature allows the transmission of analog values between any two UR-series relays supporting the fea-
ture. 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 all be using firmware
version 5.20 or higher.
The settings for direct analog input 1 are described below. 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 ana-
log 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
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 may 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
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. Refer to the FlexElements™ section for additional details on per-unit
base values.
