MaxRampRate REAL Float Time constant of low pass filter in ms. See Digital Filter on page 71
for more information.
FaultValue REAL Float
ProgValue REAL Float
LowSignal REAL Float Lower current value for scaling to engineering units. Default is 4 mA. Must be less than HighSignal
and more than minimum input range. See Scaling to Engineering Units on page 98
for more
information.
HighSignal REAL Float Upper current value for scaling to engineering units. Default is 10 mA. Must be more than LowSignal
and less than maximum input range. See Scaling to Engineering Units on page 98
for more
information.
LowEngineering REAL Float Measured quantity in engineering units that results in a signal level equal to LowSignal. See Scaling
to Engineering Units on page 98 for more information.
HighEngineering REAL Float Measured quantity in engineering units that results in a signal level equal to HighSignal. See Scaling
to Engineering Units on page 98 for more information.
LowLimit REAL Float Output signal will be clamped at this value in engineering units even if Ch0Data is lower than this.
HighLimit REAL Float Output signal will be clamped at this value in engineering units if Ch0Data is larger than this.
CalBias REAL Float Sensor offset in engineering units added to the measured signal before reporting Ch0.Data.
