Descriptions
Ramp rate for upward SP
changes. When the ramp
rate is set to zero, the SP
is used immediately.
The working setpoint of
the block after limiting
and filtering is applied.
Allows you to select
options for status
handling and processing.
The supported status
option for the PID block is
Target to Manual if Bad
IN.
The Strategy field can be
used to identify
groupings of blocks. This
data is not checked or
processed by the block.
The revision level of the
static data associated
with the function block.
The revision value will be
incremented each time a
static parameter value in
the block is changed.
Defines PID equation
structure to apply
controller action.
The user description of
the intended application
of the block.
Discrete input that
intiates external tracking.
The high and low scale
values, engineering units
code, and number of
digits to the right of the
decimal point associated
with external tracking
value (TRK_VAL).
The value (after scaling
from TRK_SCALE to
OUT_SCALE) applied to
OUT in LO mode.
