1/03 UDC 6300 Process Controller Product Manual 3

1.1 Introduction, Continued

Control Algorithms

Depending on the Control output type specified, the controller can be

configured for the following control algorithms:

• On/Off control,

• PID-A Equation,

• PID-B Equation,

• PD with Manual Reset.

• 3 Position Step Control

Duplex control can be configured for all algorithms except 3 Pos Step.

Options

Available options include:

Dual Loop / Internal Cascade Two independent loops of control or

internal cascade linking of the primary

and secondary controller in one device.

Includes output override algorithm.

Accutune Automatically adjusts the PID tuning

parameters as necessary while controlling

at setpoint in the automatic control mode.

Second Current Output Fully isolated and configurable as control

output or auxiliary output

Transmitter Power 24Vdc power to supply one or two, 4 to

20mA transmitters for the high level

inputs.

Communications Serial communications link integrates

with CRT-based RS422/485 or DMCS.

Math Options Two pre-configured algorithms have easy

implementation into either control loop.

They can be linked or used individually

and are capable of using any input with

its’ Ratio and Bias.

Gain Scheduling - 8 Gain values may be

applied to 8 Process Variable (PV) bands

for use on known non-linear processes.

Two 8-Segment Characterizers - can be

applied to Input 2, Input 4, Loop 1 Output,

or Loop 2 Output.

Polynomial Curve Characterizer-- a fifth

order polynomial equation can be used on

any one of the five analog inputs.

Totalizer Function - displays actual

current totalized value of up to 8 digits.

Digital Logic Gates - up to 5 gates can be

configured. For each gate you can select

from 8 gate types; each gate having two

input sources and one output use.
