Table C-3: Definitions of Analog Input Function Block System Parameters
(continued)
Index Number Parameter Units Description
19 FIELD_VAL Percent The value and status from the transducer block or from the
simulated input when simulation is enabled.
20 UPDATE_EVT None This alert is generated by any change to the static data.
21 BLOCK_ALM None 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 None The summary alarm is used for all process alarms 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.
23 ACK_OPTION None Used to set auto acknowledgment of alarms.
24 ALARM_HYS Percent The amount the alarm value must return within the alarm limit
before the associated active alarm condition clears.
25 HI_HI_PRI None The priority of the HI HI alarm.
26 HI_HI_LIM EU of
PV_SCALE The setting for the alarm limit used to detect the HI HI alarm
condition.
27 HI_PRI None The priority of the HI alarm.
28 HI_LIM EU of
PV_SCALE The setting for the alarm limit used to detect the HI alarm
condition.
29 LO_PRI None The priority of the LO alarm.
30 LO_LIM EU of
PV_SCALE The setting for the alarm limit used to detect the LO alarm
condition.
31 LO_LO_PRI None The priority of the LO LO alarm.
32 LO_LO_LIM EU of
PV_SCALE The setting for the alarm limit used to detect the LO LO alarm
condition.
33 HI_HI_ALM None The HI HI alarm data, which includes a value of the alarm, a
timestamp of occurrence and the state of the alarm.
34 HI_ALM None The HI alarm data, which includes a value of the alarm, a timestamp
of occurrence and the state of the alarm.
35 LO_ALM None The LO alarm data, which includes a value of the alarm, a timestamp
of occurrence and the state of the alarm.
36 LO_LO_ALM None The LO LO alarm data, which includes a value of the alarm, a
timestamp of occurrence and the state of the alarm.
37 OUT_D None Discrete output to indicate a selected alarm condition.
