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.

code and the number of digits to the right of the decimal point

to be used to display the Primary Value.

EU_100

max value

R

The engineering unit value which represents the upper end of

range of the associated Block Parameter.

R

The engineering unit value which represents the lower end of

range of the associated Block Parameter.
