Analog-Input Block
L_TYPE 16 None Linearization type. Determines whether the field value is
used directly (Direct) or is converted linearly (Indirect).
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.
SIMULATE 09 None A group of data that contains the current transducer value
and status, the simulated transducer value and status, and
the enable/disable bit.
STRATEGY 03 None The strategy field can be used to identify grouping of blocks.
This data is not checked or processed by the block.
ST_REV 01 None The revision level of the static data associated with the
function block. The revision value will be incremented each
time a static parameter value in the block is changed.
TAG_DESC 02 None The user description of the intended application of the block.
UPDATE_EVT 20 None This alert is generated by any change to the static data.
VAR_INDEX 39 % of OUT Range The average absolute error between the PV and its previous
mean value over that evaluation time defined by VAR_SCAN.
VAR_SCAN 40 Seconds The time over which the VAR_INDEX is evaluated.
XD_SCALE 10 None The high and low scale values, engineering units code, and
number of digits to the right of the decimal point associated
with the channel input value.
