Channels view parameters (HART Output)

The
Channels
 view includes these parameters:
Parameter
Description
Channel
Shows the channel number to which this configuration applies.
Output Range
Determines the output range for the Current output.
Enable HART
Enables HART functionality on the channel.
Output State During
Program Mode
Determines channel action when the controller transitions to Program mode.
  • Hold Last State
     causes the output to remain at the last value sent from the controller prior to being placed in Program Mode.
  • User Defined Value
     forces the output to whatever value is entered in the field. The value is entered in the
    Ch0x
    view in the engineering units defined by the scaling parameters for the channel.
Output State During
Fault Mode
Determines channel action when a fault occurs.
  • Hold Last State
     causes the output to remain at the last value sent from the controller prior to loss of communication.
  • User Defined Value
     forces the output to whatever value is entered in the field. The value is entered in the engineering units defined by the scaling parameters for 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.
Enable Diagnostics
Enables short circuit and open wire detection on the channel when selected.
