19 4019 4119 –FIELD_VAL
TA0102-2.EPS
–
20 4020 4120 –UPDATE_EVT
–
Raw value of the field device in percent of thePV
range, with a status reflecting the Transducer
condition, before signal characterization (L_TYPE)
or filtering (PV_FTIME).
21 4021 4121 –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 EnableALARM_SUM
The current alert status, unacknowledged states,
unreported states, and disabled states of the alarms
associated with the function block.
–
23 4023 4123 0xFFFFACK_OPTION
Selection of whether alarms associated with the
block will be automatically acknowledged.
AUTO
24 4024 4124 0.5% ALARM_HYS
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.
AUTO
AUTO
25 4025 4125 0HI_HI_PRI
Priority of the high high alarm.
AUTO
26 4026 4126 +INFHI_HI_LIM
The setting for high high alarm in engineering units.
AUTO
27 4027 4127 0HI_PRI
Priority of the high alarm.
AUTO
28 4028 4128 +INFHI_LIM
The setting for high alarm in engineering units.
AUTO
29 4029 4129 0LO_PRI
Priority of the low alarm.
AUTO
30 4030 4130 –INFLO_LIM
The setting for the low alarm in engineering units.
AUTO
31 4031 4131 0LO_LO_PRI
Priority of the low low alarm.
AUTO
32 4032 4132 –INFLO_LO_LIM
The setting of the low low alarm in engineering units.
–
33 4033 4133 –HI_HI_ALM
The status for high high alarm and its associated time stamp.
–
34 4034 4134 –HI_ALM
The status for high alarm and its associated time stamp.
–
35 4035 4135 –LO_ALM
The status of the low alarm and its associated time stamp.
–
36 4036 4136 –LO_LO_ALM
The status of the low low alarm and its associated
time stamp.
This alert is generated by any change to the static data.
17 4017 4117 Linear: 0%
Square root: 10%
LOW_CUT
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, in % of
scale. This feature may be used to eliminate noise
near zero for a flow sensor.
AUTO
18 4018 4118 2secPV_FTIME
Time constant of a single exponential filter for the
PV, in seconds.

CHANNEL
The number of the logical hardware channel that is
connected to this I/O block. This information
defines the transducer to be used going to or from
the physical world.
O/S
16 4016 4116 Specified at the
time of order
L_TYPE
Determines if the values passed by the transducer
block to the AI block may be used directly (Direct)
or if the value is in different units and must be
converted linearly (Indirect), or with square root (Ind
Sqr Root), using the input range defined by the
transducer and the associated output range.
