PID Function Block
Range Initial Value
Data Type: Unsigned16
The revision level of the static data associated
with the function block. The revision value will be
0
incremented each time a static pa rameter value
in the block is changed.
Data Type: Octet String
Spaces The user description of the intended application
of the block.
Data Type: Unsigned16
The strategy field can be used to identify
0
grouping of blocks. This data is not checked or
processed by the block.
Data Type: Unsigned8
The identification number of the plant unit. This
0
information may be used in the host for sorting
alarms, etc.

Dynamic This parameter reflects the error status
associated with the hardware or software
components associated with a block. It is a bit
string so that multiple errors may be shown.
Data Type: DS-65
Dynamic
The process variable used in block execution.
Data Type: DS-65
The target block setpoint value. It is the result of
Dynamic
setpoint limiting and setpoint rate of change
limiting.
Dynamic
DS-65
The block output value and status.
100 Data Type: DS-68
0 The high and low scale values, engineering units
% code, and number of digits to the right of the
2 decimal point associated with PV.
