DV_LO_PRI
Priority of the low deviation alarm.
FAULT_STATE
Condition set by loss of communication to an output block, fault promoted to an output block or a
physical contact. When Fault State condition is set, then output function blocks will perform their
FSTATE actions.
FEATURE_SEL
Used to select resource block options.
FEATURES
Used to show supported resource block options.
FF_GAIN
The gain that the feed forward input is multiplied by before it is added to the calculated control
output.
FF_SCALE
The feedforward input high and low scale values, engineering units code, and number of digits to the
right of the decimal point.
FF_VAL
The feed forward value and status.
FIELD_VAL
Raw value of the field device in percent of the PV range, with a status reflecting the Transducer condi-
tion, before signal characterization (L_TYPE) or filtering (PV_FTIME).
FIELD_VAL_D
Raw value of the field device discrete input, with a status reflecting the Transducer condition.
FREE_SPACE
Percent of memory available for further configuration. Zero in a preconfigured resource.
FREE_TIME
Percent of the block processing time that is free to process additional blocks.
FSTATE_TIME
The time in seconds from detection of fault of the output block remote setpoint to the output action of
the block output if the condition still exists.
FSTATE_VAL
The preset analog SP value to use when fault occurs. This value will be used if the I/O option Fault
State to value is selected.
FSTATE_VAL_D
The preset discrete SP_D value to use when fault occurs. This value will be used if the I/O option
Fault State to value is selected.
GAIN
Dimensionless value used by the block algorithm in calculating the block output.
GRANT_DENY
Options for controlling access of host computer and local control panels to operating, tuning and
alarm parameters of the block.
