Analog Input (AI) Function Block
HI_HI_LIM 26 EU of PV_SCALE The setting for the alarm limit
used to detect the HI HI alarm
condition.
HI_HI_PRI 25 None The priority of the HI HI alarm.
HI_LIM 28 EU of PV_SCALE The setting for the alarm limit
used to detect the HI alarm
condition.
HI_PRI 27 None The priority of the HI alarm.
IO_OPTS 13 None Allows the selection of
input/output options used to alter
the PV. Low cutoff enabled is the
only selectable option.
L_TYPE 16 None Linearization type. Determines
whether the field value is used
directly (Direct), is converted
linearly (Indirect), or is converted
with the square root (Indirect
Square Root).
LO_ALM 35 None The LO alarm data, which
includes a value of the alarm, a
timestamp of occurrence and the
state of the alarm.
LO_LIM 30 EU of PV_SCALE The setting for the alarm limit
used to detect the LO alarm
condition.
LO_LO_ALM 36 None The LO LO alarm data, which
includes a value of the alarm, a
timestamp of occurrence and the
state of the alarm.
LO_LO_LIM 32 EU of PV_SCALE The setting for the alarm limit
used to detect the LO LO alarm
condition.
LO_LO_PRI 31 None The priority of the LO LO alarm.
LO_PRI 29 None The priority of the LO alarm.
LOW_CUT 17 % If percentage value of transducer
input fails below this, PV = 0.
MODE_BLK 05 None The actual, target, permitted, and
normal modes of the block.
Target: The mode to “go to”
Actual: The mode the “block is
currently in”
Permitted: Allowed modes that
target may take on
Normal: Most common mode for
target
OUT 08 EU of OUT_SCALE The block output value and status.
OUT_D 37 None Discrete output to indicate a
selected alarm condition.
OUT_SCALE 11 None The high and low scale values,
engineering units code, and
number of digits to the right of the
decimal point associated with
OUT.
PV 07 EU of XD_SCALE The process variable used in
block execution.
PV_FTIME 18 Seconds The time constant of the
first-order PV filter. It is the time
required for a 63% change in the
IN value.
