4017 4117 4217 4317 4417 LOW_CUT Linear: 0%
Square root:
10%
AUTO
Limit used in square root processing. A value of zero
percent of scale is used in block processing if the
transducer value falls below this limit. This feature
may be used to eliminate noise near zero for a
flow sensor. The setting is in an engineering unit of
OUT_SCALE.
18
4018 4118 4218 4318 4418 PV_FTIME 0 (s)
AUTO
Time constant of a single exponential filter for the PV,
in seconds.
19
4019 4119 4219 4319 4419 FIELD_VAL —
—
Raw value of the field device in percent of the
PV range, with a status reflecting the Transducer
condition, before signal characterization (L_TYPE) or
filtering (PV_FTIME).
20
4020 4120 4220 4320 4420 UPDATE_
EVT
—
—
This alert is generated by any change to the static
data.
21
4021 4121 4221 4321 4421 BLOCK_
ALM
—
—
The block alarm is used for all configuration,
hardware, connection failure or system problems
in the block. The cause of the alert is entered in the
subcode field. The first alert to become active will
set the Active status in the Status attribute. As soon
as the Unreported status is cleared by the alert
reporting task, another block alert may be reported
without clearing the Active status, if the subcode has
changed.
22
4022 4122 4222 4322 4422 ALARM_
SUM
Enable
—
The current alert status, unacknowledged states,
unreported states, and disabled states of the alarms
associated with the function block.
23
4023 4123 4223 4323 4423 ACK_
OPTION
0xFFFF
AUTO
Selection of whether alarms associated with the
block will be automatically acknowledged.
24
4024 4124 4224 4324 4424 ALARM_
HYS
0.5%
AUTO
Amount the PV must return within the alarm limits
before the alarm condition clears. Alarm Hysteresis is
expressed as a percent of the PV span.
25
4025 4125 4225 4325 4425 HI_HI_PRI 0
AUTO
Priority of the high high alarm.
26
4026 4126 4226 4326 4426 HI_HI_LIM +INF
AUTO
The setting for high high alarm in engineering units.
27

Priority of the low low alarm.
32
4032 4132 4232 4332 4432 LO_LO_LIM –INF
AUTO
The setting of the low low alarm in engineering units.
33
