BLOCK_ALM BLOCK_ALM BLOCK_ALM BLOCK_ALM
Block Alarm Block Alarm Block Alarm Block Alarm
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.
-
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
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
R/W 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.
Uninitialized
Setting:
0 Uninitialized
1 (volume flow in m
3 /s)
2 (mass flow in kg/s)
3 (speed in m/s)
4 (coil temperature in °C)
5 (conductivity in S/m)
6 (electronic temperature in °C)
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 analog 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
Bad: NonSpecific:
NotLimited
VALUE
Value
R A numerical quantity entered by a user or calculated by the
algorithm.
