R/W Determines if the values passed by the TB 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.
Uninitialized
Setting:
Uninitialized / Direct / Indirect / Ind Sqr Root

Settings of 5 subelements for previous 2 parameters "Low Alarm" and "Low Low Alarm":
UNACKNOWLEDGED
Unacknowledged
R/W A discrete enumeration which is set to "Unacknowledged"
when an alarm occurs, and set to "Acknowledged" by a write
from a human interface device or other entity which can
acknowledge that the alarm/event has been noticed.
Uninitialized
Setting:
Uninitialized / Acknowledged / Unacknowledged
ALARM_STATE
Alarm State
R A discrete enumeration which gives an indication of whether
the alert is active and whether it has been reported.
Uninitialized
Setting:
Uninitialized / Clear - reported / Clear - not reported / Active -
reported / Active - not reported
TIME_STAMP
Time Stamp
R The time when evaluation of the block was started and a
change in alarm/event state was detected that is unreported.
The time stamp value will be maintained constant until alert
confirmation has been received - even if another change of
state occurs.
Uninitialized
Setting:
MM / DD / YY (Month / Day / Year)
HH:MM:SS (Hour:Minute:Second)
SUB_CODE
Subcode
R An enumeration specifying the cause of the alert to be
reported.
Other
Setting:
Other / Block Configuration / Link Configuration / Simulation
Active / Local Override / Device Fault State / Device
Maintenance / Input Failure / Output Failure / Memory
Failure / Lost Static Data / Lost NV Data / Readback Check /
Maintenance Needed / Power Up / Out Of Service
VALUE
Float value
R A numerical quantity entered by a user or calculated by the
algorithm.
