Description / Range / Selections / Note
16 L_TYPE RW S U8 1 S
0 Uninitialized ** Doesn’t allow at the AI to move out from OOS
1 Direct PV = CHANNEL_VALUE – To be used when XD_SCALE = OUT_SCALE
2 Indirect
PV = FIELD_VAL% * (OUT_SCALE_100% - OUT_SCALE_0%) + OUT_SCALE_0%
To be used when XD_SCALE != OUT_SCALE
3 Indirect Square Root
IF FIELD_VAL < 0.0 when PV = OUT_SCALE 0%
ELSE IF FIELD_VAL < LOW_CUT when PV = OUT_SCALE 0%
ELSE when PV = √ Field_Val% * (OUT_SCALE_100% - OUT_SCALE_0%) + OUT_SCALE_0%
17 LOW_CUT RW S FLT 4 S 0 or >0
Limit used in square root processing. A value of zero percent of scale is used in block
processing if the transducer falls below this limit, in % of scale. The features may be
used to eliminate noise near zero for a flow sensor.
18 PV_FTIME RW S FLT 4 S 0….60 seconds
Time constant of a single exponential filter for the PV, expressed in seconds. This is the
time necessary for reach the 63% of the variation in input.
19 FIELD_VAL R R DS-65 5 D
The percent of the value from the
Transducer block or from the
simulation value, when enabled,
before the characterisation (L_TYPE)
and Filtering (PV_FTIME).
20 UPDATE_EVT R R DS-73 14 D This alert is generated by any change to the static data
21 BLOCK_ALM RW R DS-72 13 D
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 parameter. 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 ALARM_SUM RW R DS-74 8 mix
The summary alarm is used for all process alarm 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 parameter. As soon as the Unreported status is cleared by the alert
reporting task, another block alert may be reported without clearing the Actve Status, if the subcode has changed.
23 ACK_OPTION RW S B_STR 2 S Used to set auto acknowledgment of the alarms
24 ALARM_HYS RW S FLT 4 S
0 or > 0 expressed as percent of
the OUT_SCALE span
(default =[0.5%])
Alarm Hysteresis is the amount the PV must return within the alarm limit before the alarm
condition clears.
25 HI_HI_PRI RW S U8 1 S 0 - 15
Expressed in OUT_SCALE unit.
26 HI_HI_LIM RW S FLT 4 S Critical Limit High
27 HI_PRI RW S U8 1 S 0 - 15
28 HI_LIM RW S FLT 4 S Advisory Limit High
29 LO_PRI RW S U8 1 S 0 - 15
30 LO_LIM RW S FLT 4 S Advisory Limit Low
31 LO_LO_PRI RW S U8 1 S 0 - 15
32 LO_LO_LIM RW S FLT 4 S Critical Limit Low
33 HI_HI_ALM RW R DS-71 16 D Critical High Alarm
34 HI_ALM RW R DS-71 16 D Advisory High Alarm
FIELD_VAL = 100 *
CHANNEL_VALUE – XD_SCALE_0%
XD_SCALE_100% – XD_SCALE_0%
