Low Scaling Value

The low engineering value corresponding to the analog
value of 0. The low scaling value must always be less than
the high scaling value (-32768 < x < high scaling value).

PID Controller Name

The name of the control loop. Follows the same format as
tag names. The controller name must not be the name of a
variable.

PID Controller Title

A controller may be given a title containing up to 40
characters of descriptive text. This is the only optional
parameter for a controller.

Input

The name of the process variable which is to be maintained
at the desired setpoint.

High Scaling Value

The high engineering value corresponding to the analog
value of 4,095. The high value must always be greater
than the low value (low scaling value < x < 32767).

Scaling Type

Choose the Linear option button for linear value
conversion. Choose the Square Root option button for
square root extraction (square root extraction is typically
used to linearize flow signals that are measured using
differential pressure transmitters).

Output

The name of the variable which receives the result of the
current control computation.

Output Bias %

The bias portion of the control loop. May be in the range
0.0 to 100%. The default value is 0.0%. The corrective
output that maintains the output at the setpoint.

Output Delta %

The maximum change of output allowed between two loop
calculations. May be in the range 0.0 to 100%. The default
value is 100%.
