Value
C.ProgToFaultEn
Decimal
BOOL
Sets outputs to selected Fault state when the owner-
controller is in Program mode.
0 = outputs use Program mode setting
1 = outputs use fault mode settings
0
C.Operations[0].FilterControl
(1)
Decimal
SINT
bit 0 = 1 - apply filter to F0
bit 1 = 1 - apply filter to G0
bit 2 = 1 - apply 1second debounce to G0
0
C.Operations[0].MeterSamples
Decimal
SINT
50
C.Operations[0].ThresholdControl
Decimal
SINT
Sets flowmeter input threshold control
0 = 50mV threshold (magnetic pickup)
1 = 1.3V threshold (TTL)
2 = 4.0V threshold (PreAmp)
0
C.Operations[0].CalculationType
Decimal
SINT
Sets calculation type
0 = Counts/K-factor x MeterFactor correction x CCF
1 = Counts/K-factor x MeterFactor correction x AGA 7
compensation or CCF if CCF is not equal to 0.0
0
C.Operations[0].AccelCalculation
Decimal
SINT
Number of past samples to use to calculate an acceleration
value.
Sample range is 0 to 255.
50
C.Operations[0].MinDetectableFreq
Float
REAL
User-defined value from 0 - 120,000.
Sets FreqAverage, FreqPeriod, Speed, GrossRate, and
NetRate reading to 0 when calculated value is less than
value entered. GrossVolume, and NetVolume do not
increment below this value even though TotalCounts
increments over time.
5
C.Operations[0].HighestAllowedFreq
Float
REAL
User-defined value between MinDetectableFreq and
120,000
When the frequency reaches this level, it sets the
Overspeed alarm limit
3700
C.Operations[0].AccelAlarmValue
Float
REAL
Sets Acceleration alarm limit
-Maximum acceleration (cycles per second
2
)
<AccelAlarmValue< +Maximum acceleration (cycles per
second
2
)
100
C.Operations[0].MeterFactor
Float
REAL
Calibration Adjust for metering reading applied after K-
factor correction. Typically, this factor is between 0.8 and
1.2 but the module restricts the value>0.
C.Operations[0].FilterResolution
Float
REAL
Sets resolution of the Speed calculation based on the raw
counts
0 = default of 0.00001
0.00001 = resolution of + 1 count of 100,000 raw counts.
0.166
C.Operations[0].SampleTime
Float
REAL
Sets time for a sample to be taken.
(2.0 second maximum sample time for High Resolution
Frequency mode and 5.0 seconds for Totalizer mode)
0.5
C.Operations[0].kFactStruct.kFactorForChan[0]
Float
REAL
K-factor 0 for Channel 0 when frequency is <
FreqAtKFactor[1]
600.0
C.Operations[0].kFactStruct.kFactorForChan[1]
Float
REAL
This tag is an ordered pair with tag
C.Operations[0].kFactStruct.FreqAtKFactor [1]
600.0
C.Operations[0].kFactStruct.kFactorForChan[2]
Float
REAL
This tag is an ordered pair with tag
C.Operations[0].kFactStruct.FreqAtKFactor [2]
550.0
C.Operations[0].kFactStruct.kFactorForChan[3]
Float
REAL
This tag is an ordered pair with tag
C.Operations[0].kFactStruct.FreqAtKFactor [3]
0.0
C.Operations[0].kFactStruct.kFactorForChan[4]
Float
REAL
This tag is an ordered pair with tag
C.Operations[0].kFactStruct.FreqAtKFactor [4]
0.0
