Update State

R

A discrete enumeration which gives an indication of whether

the alert has been reported.

Uninitialized

Setting:

Uninitialized / Update reported / Update 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

Balance Time

R/W

This specifies the time for the internal working value of bias or

ratio to return to the operator set bias or ratio, in seconds. In

the PID block, it may be used to specify the time constant at

which the integral term will move to obtain balance when the

output is limited and the mode is Auto, Cas, or RCas.
