UNACKNOWLEDGED
Unacknowledged
RW 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
Value
R The value of the associated parameter at the time the alert was
detected.
0
Setting:
0...255
CHANNEL CHANNEL CHANNEL CHANNEL
Channel Channel Channel Channel
RW 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.
0
Setting:
0. Uninitialized
1. Level
2. Distance
3. Conversion
4. Distance conversion
FIELD_VAL FIELD_VAL FIELD_VAL FIELD_VAL
Field Value Field Value Field Value Field Value
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).
STATUS
Status
R Digital transducers, unlike their analogue versions, can detect
faults that make the measurement bad or prevent the actuator
from responding. This additional, valuable information will be
passed along with each transmission of a data value in the
form of a status attribute.
VALUE
Value
R A numerical quantity entered by a user or calculated by the
algorithm.

Options for controlling access of host computers and local
control panels to operating, tuning and alarm parameters of
the block.
