AO Control - Pre‐Characterization
Setpoint
Setpoint (FINAL_VALUE.VALUE [13.2]) shows the value of the setpoint in % (percent) of ranged travel or pressure.
Setpoint is used for both travel and pressure control. This parameter will be written directly if the transducer block is in
MAN mode, or will be written automatically by the AO block if the transducer block is in AUTO mode.
Setpoint Status
Shows the Foundation Fieldbus status of Setpoint Value (FINAL_VALUE.STATUS [13.2]); Good, Uncertain, or Bad.
Travel (DeChar)
Travel (FINAL_POSITION_VALUE.VALUE [17.2]) shows the value of the travel in % (percent) of ranged travel. Travel
always represents how far the valve is open.
AO Control‐Post Characterization
Travel Target
Travel target is the output from the characterization function.
Travel
Travel (TRAVEL.VALUE [34.2]) displays the actual position of the valve in percent (%) of calibrated travel.
Travel Status
Shows the Foundation Fieldbus status of Travel Value (TRAVEL.STATUS [34.1]); Good, Uncertain, or Bad.
DO Control
Setpoint(D)
Discrete Setpoint (SETPOINT_D.VALUE [32.2]) shows the value of the setpoint in discrete values.
0 = closed, 1 = open, 5, 10, 15... = setpoint in 5% units. This parameter will be written directly if the transducer block is
in MAN mode, or will be written automatically by the DO block if the transducer block is in AUTO mode.
Travel(D)
Travel (TRAVEL_D.VALUE [33.2]) shows the value of the setpoint in discrete values.
0 = closed, 1 = open, 5, 10, 15... = setpoint in 5% units.
Input Characterization
Input Characterization (INPUT_CHAR [50]) defines the relationship between the setpoint specified by the output
function block and the desired valve position.
