Descriptions
The DV HI alrm data,
which includes the value
of the alarm, a timestamp
of occurrence, and the
state of the alarm.
The setting for the alarm
limit used to detect the
deviation high alarm
condition.
The priority of the
deviation high alarm.
The DV LO alarm data,
which includes a value of
the alarm, a timestamp of
occurrence, and the state
of the alarm.
The setting for the alarm
limit used to detect the
deviation low alarm
condition.
The priority of the
deviation low alarm.
The error (SP-PV) used to
determine the control
action.
Enables the use of
feedforward calculations.
The feedforward gain
value. FF_VAL is
multiplied by FF_GAIN
before it can be added to
the calculated control
output.
The high and low scale
values, engineering units
code, and number of
digits to the right of the
decimal point associated
with the feedforward
value (FF_VAL).
The proportional gain
value. This value cannot
equal
.
