STRATEGY 03 None The strategy field can be used to identify grouping 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 initiates 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 the 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.
UBETA 72 Percent Used to set disturbance rejection vs. tracking response action for a 2.0 degree of
freedom PID.
UGAMMA 71 Percent Used to set disturbance rejection vs. tracking response action for a 2.0 degree of
freedom PID.
UPDATE_EVT 43 None This alert is generated by any changes to the static data.
