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 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. Time stamp records the time when parameter
was updated.
Uninitialized
Setting:
MM / DD / YY (Month / Day / Year)
HH:MM:SS (Hour:Minute:Second)
Static Revision 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
Setting:
0…65535
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
Setting:
0…65535

Drive Level
The measured drive level value and status of available to the
Function Block. (Fct. B2.11)

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.
