4Ć15DCP Configuration

Original Ć June 1990 CE4.2:CL6211

Gain Ċ The proportional gain for BIAS AND GAIN, P_PD WITH BIAS,

and PI/PID/I Direct Control points. The valid range for gain is any floating

point number from 0.0 to 128.0, and is tunable using DDP #3, GAIN.

Gain Limit Ċ The proportional gain limit for the ERROR_SQUARE

PI/PID, and ADAPTIVE_GAIN PI/PID Direct Control points. The valid

range for gain limit is any floating point number from 0.0 to 128.0, and

can be changed using DDP #4, GAIN LM. For the ADAPTIVE_GAIN

PI/PID PCA type, if the gain limit is greater than the gain value, the limit

serves as a high gain limit; if the gain limit is less than the gain value, the

limit serves as a low gain limit.

PCA Type Ċ The PCA of the Direct Control point determines the

algorithm that will be used to process the PV. The PCA is defined on the

Direct Control Point form, and is displayed here for reference only.

Rate Ċ Used to define the derivative gain of a P/PD WITH BIAS or

PI/PID/I Direct Control point. The valid range for rate is any floating point

value from 0.0 to 895.0 minutes. The rate time may be changed using

DDP #6, RATE.

Ratio Enable Ċ Determines whether this point supports the Ratio value.

The valid range is YES or NO. This configuration item cannot be

changed from the DDP list.

Reset Ċ Used to define the integral gain of a PI/PID/I Direct Control

point. The valid range for reset is any floating point value from 0.0 to

293.0 repeats per minutes. The reset value may be changed using DDP

#5, RESET.

Restart Bias Ċ Defines the initial value of the bias after a power fail

restart, if the Restart from Last Bias enable configuration item is

answered NO. The valid range is -113.97 to 113.97 percent for the BIAS

AND GAIN PCA, and -13.97 to 113.97 percent for the P_PD WITH BIAS

PCA. The restart bias value may be changed using DDP #31, RST BIAS.

Restart from Last Bias Ċ This configuration item allows the use of the

Restart Bias value after a power fail has occurred. If NO is selected, the

restart bias value defined in the Restart Bias configuration item is used.

If YES is selected, the last bias value prior to power fail is restored upon

restart. This configuration item is valid for Bias and Gain and P/PD WITH

BIAS PCAs.

Restart from Last Ratio Ċ This configuration item allows the use of the

Restart Ratio value after a power fail has occurred. If NO is selected, the

restart Ratio value defined in the Restart Ratio configuration item is used.

If YES is selected, the last Ratio value prior to power fail is restored upon

restart.
