Table 8-25: PID Function Block System Parameters
(continued)
Parameter Index number Units Descriptions
SP_RATE_UP 20 EU of PV_SCALE per
second
Ramp rate for upward SP
changes. When the ramp
rate is set to zero, the SP
is used immediately.
SP_WORK 68 EU of PV_SCALE The working setpoint of
the block after limiting
and filtering is applied.
STATUS_OPTS 14 None 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.
STRATEGY 03 None The Strategy field can be
used to identify
groupings of blocks. This
data is not checked or
processed by the block.
ST_REV 01 None 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.
STRUCTURE CONFIG 75 None Defines PID equation
structure to apply
controller action.
TAG_DESC 02 None The user description of
the intended application
of the block.
TRK_IN_D 38 None Discrete input that
intiates external tracking.
TRK_SCALE 37 None 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).
TRK_VAL 39 EU of TRK SCALE The value (after scaling
from TRK_SCALE to
OUT_SCALE) applied to
OUT in LO mode.
