• PhasorXUseFreqSrc: Enables/Disables the contribution of Phasor channel
X in automatic frequency source selection by choosing On/Off setting.
Each voltage-connected preprocessor block delivers the frequency data,
derived from the analog input AC voltage values, to the respective voltage
phasor channel. Every phasor channel has a user-settable parameter
(PhasorXUseFreqSrc) to be used as a source of frequency data for
reporting to the PDC client. It is very important to set this parameter to On
for the voltage-connected phasor channels. There is an automatic frequency
source selection logic to ensure an uninterrupted reporting of the system
frequency to the PDC client. More information is available under the
section Frequency
3. ANALOGREPORT is the function block responsible for reporting the analog
values. Each instance of ANALOGREPORT function block has 24 analog
channels with the following setting parameters; where X is a number from 1 to 24:
• AnalogXRange: This parameter defines a range between -AnalogXRange
and +AnalogXRange for AnalogX value. The range will be used by the IED
to apply a proper scale factor to the AnalogX values when Integer format is
used. It refers to the 4-byte ANUNIT field of the configuration frames 1, 2
organization and the 8-byte ANSCALE field of the configuration frame 3
organization defined in IEEE C37.118.2 message format. The
AnalogXRange value can be a number between 3277.0 and 10000000000.
This setting is only important if the AnalogDataType setting is selected as
Integer. More information is available under the section
ANALOGREPORT
• AnalogXUnitType: Unit type for analog signal X. It refers to the 4-byte
ANUNIT field of the configuration frames 1, 2 organization defined in
IEEE C37.118.2 message format. The options are Single point-on-wave,
RMS of analog input and Peak of analog input.
