DIV_HI_ALARM 64 None The DV HI alrm data,
which includes the value
of the alarm, a timestamp
of occurrence, and the
state of the alarm.
DV_HI_LIM 57 EU of PV_SCALE The setting for the alarm
limit used to detect the
deviation high alarm
condition.
DV_HI_PRI 56 None The priority of the
deviation high alarm.
DV_LO_ALM 65 None The DV LO alarm data,
which includes a value of
the alarm, a timestamp of
occurrence, and the state
of the alarm.
DV_LO_LIM 59 EU of PV_SCALE The setting for the alarm
limit used to detect the
deviation low alarm
condition.
DV_LO_PRI 56 None The priority of the
deviation low alarm.
ERROR 67 EU of PV_SCALE The error (SP-PV) used to
determine the control
action.

feedforward calculations.
FF_GAIN 42 None The feedforward gain
value. FF_VAL is
multiplied by FF_GAIN
before it can be added to
the calculated control
output.
FF_SCALE 41 None 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).
