Channels view parameters (HART Input)

The
Channels
 view includes these parameters:
Parameter
Description
Channel
Shows the channel number to which this configuration applies.
Input Range
Determines input range for the Current input.
Enable HART
Enables HART functionality on the channel.
High Signal
Sets one of the four constants in the scaling equation.
High Signal
 is in terms of the input signal units and corresponds to
High Engineering
 when scaled.
High Signal
 must be greater than
Low Signal
.
Low Signal
Sets one of the four constants in the scaling equation.
Low Signal
 is in terms of the input signal units and corresponds to
Low Engineering
 when scaled.
Units (Signal)
Shows the unit of measurement for
High Signal
 and
Low Signal
.
High Engineering
Sets one of the four constants in the scaling equation.
High Engineering
 corresponds to
High Signal
 and helps determine the engineering units that the signal values scale into.
Low Engineering
Sets one of the four constants in the scaling equation.
Low Engineering
 corresponds to
Low Signal
 and helps determine the engineering units that the signal values scale into.
Units (Engineering)
Shows the unit of measurement for
High Engineering
 and
Low Engineering
 and for the channel’s input value.
Digital Filter
Sets the time constant for a first order lag filter used to smooth noise transients on the input with a range from 0 through 32767. When set to 0, no filtering takes place.
Disable Alarms
Determines whether process alarms are generated.
  • If selected, the device does not generate process alarms.
  • If cleared, the device generates process alarms.
Enable Diagnostics
Enables short circuit and open wire detection on the channel when selected.
