AO Control - Pre‐Characterization
Final Value Setpoint (FINAL_VALUE.VALUE [14.2]) 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.
Final Value Status (FINAL_VALUE.STATUS [14.1]) shows the Foundation Fieldbus status of Setpoint Value ; Good,
Uncertain, or Bad.
Travel (DeChar) (FINAL_POSITION_VALUE.VALUE [18.2]) shows the value of the travel in % (percent) of ranged travel.
Travel always represents how far the valve is open.
AO Control‐Post Characterization
Working Setpoint is the output from the characterization function.
Working Setpoint Value (WORKING_SP.VALUE [20.2]) displays the actual position of the valve in percent (%) of
calibrated travel.
Working Setpoint Status (WORKING_SP.STATUS [20.1]) shows the Foundation Fieldbus status of Travel Value; Good,
Uncertain, or Bad.
DO Control
Working Setpoint(D) (WORKING_SP_D.VALUE [35.2]) 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.
Discrete Working Postion(D) shows the value of the setpoint in discrete values.
0 = closed, 1 = open, 5, 10, 15... = travel in 5% units.
Instrument Info
Temperature (TEMPERATURE [75]) displays the internal temperature of the instrument in either degrees Fahrenheit or
Celsius.
Protection (PROTECTION [104]) Indicates the status of Protection.
Travel/Pressure State (TVL_PRESS.STATE [65.2]) indicates if the instrument is being used for travel control (position
control) or as an I/P (pressure control).
Characterization (INPUT_CHAR [76]) defines the relationship between the setpoint specified by the output function
block and the desired valve position.
PD Inside Status (PD_STATUS [105.2]) shows the status of Performance Diagnostics.
