Error Rate

The maximum rate of change of error allowed for the loop
calculation (in engineering units). May be in the range 0 <
x < Scaling Range. There is no default value.

Differential

Applicable only to the derivative term, calculations may be
based on Error or Process differential. The default value is
Error.

Error SQR P

Enables proportional action to be based on error (No) or
error squared (Yes). The default value is No.

Error SQR I

Enables integral action to be based on error (No) or error
squared (Yes). The default value is No.

Error Deadband

The distance above and below the setpoint for which the
error is ignored (in engineering units). May be in the
range 0 < x < Scaling Range. There is no default value.

Simple/Mod (Error Mode)

Determines the way in which the error within the
deadband is treated. In Simple mode, the error is treated
as zero for P, I and D terms. In Modified mode, the error is
treated as zero for P and D terms and Integral action is
calculated using the error value. The default value is
Simple

Low Deviation

The smallest change about the setpoint that causes a
warning alarm (in engineering units). May be in the range
0 < x < Deviation High. There is no default value.

High Deviation

The largest change about the setpoint that causes a
warning alarm (in engineering units). May be in the range
Deviation Low < x < Scaling Range. There is no default
value.
