UPDATE_STATE
Update State
R A discrete enumeration which gives an indication of whether the
alert has been reported.
Uninitialized
Setting:
• Uninitialized
• Reported
• 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.
Setting:
MM / DD / YY (Month / Day / Year)
HH:MM:SS (Hour:Minute:Second)
STATIC_REVISION
Static Rev
R The static revision of the block whose static parameter was
changed and is being reported. It is possible for the present value
of static revision to be greater than this because static can be
changed at any time.
0
RELATIVE_INDEX
Relative Index
R The OD index of the static parameter whose change caused this
alert, minus the FB starting index. If the update event was caused
by a write to multiple parameters at the same time, then this
attribute will be zero.
0
XD_SCALE XD_SCALE XD_SCALE XD_SCALE
Transducer Scale
The high and low scale values, engineering units code, and
number of digits to the right of the decimal point used with the
value obtained from the transducer for a specified channel.
EU_100
EU at 100%
RW The engineering unit value which represents the upper end of
range of the associated block parameter.
100.0
EU_0
EU at 0%
RW The engineering unit value which represents the lower end of
range of the associated block parameter.
0.0
UNITS_INDEX
Units Index
RW Device Description units code index for the engineering unit
descriptor for the associated block value.
Depends on the
