Definitions of analog input function block system parameters (continued)Table 7-20:
Parameter Index number Units Description
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 trans-
ducer input fails below this,
PV = 0.
MODE_BLK 05 None The actual target, permit-
ted, 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 val-
ues, engineering units code,
and a 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% val-
ue change in the IN value.
SIMULATE 09 None A group of data that con-
taines the current transduc-
er value and status, the si-
mulated transducer value
and status, and the enable/
disable bit.
