DCP200 Profile Controller & Recorder - Product Manual

15 Appendix 1 – Glossary of Terms Used

Active Setpoint

The term Active Setpoint is used to describe the currently selected setpoint when the instrument is in Controller Mode. Controllers can use Local Setpoint 1 and/or the Alternative Setpoint. Only one of the setpoints can be active at any time. During Profiler Control, the setpoint value is controlled by the profiler function.

Also refer to: Actual Setpoint, Alternative Setpoint, Controller Mode, Local Setpoints, Profiler Mode, Remote Setpoint, Setpoint, and Setpoint Selection.

Actual Setpoint

Actual Setpoint is the effective current value of the active setpoint. This will be different to the Active Setpoint’s target value if the setpoint is ramping. The actual setpoint will rise or fall at the ramp-rateset, until it reaches its target setpoint value. During Profiler Control, the Actual Setpoint value is controlled by the profiler function.

Also refer to: Active Setpoint, Controller Mode, Profiler Mode, Setpoint, Setpoint Ramp Rate and Setpoint Selection.

Alarm Configuration

A sub-menu of Configuration Mode used to adjust the alarm parameters. (Alarm types, values, hysteresis and inhibiting).

Also refer to: Alarm Hysteresis, Alarm Inhibit, Alarm Operation, Alarm Types and Configuration Mode.

Alarm Hysteresis

An adjustable band through which the process variable must pass before the alarm will change state. This Hysteresis is only applicable to alarms based on the Process Value or Control Deviation, as illustrated below. The band is always on the “safe” side of an alarm point, e.g. a high alarm’s hysteresis band is below the high alarm value, and a low alarm’s hysteresis is above the low alarm value. Rate Of Change Alarms have a different type of

hysteresis based on the length of time the rate is above the threshold.

 

Settings = 1 LSD to full span from the setpoint.

Default value = 1 LSD.

Refer to the Alarm Hysteresis Operation diagram on the next page.

Also refer to: Alarm Types, Loop Alarm, Alarm Operation, LSD, Minimum Duration Of Change, Process Variable, and Rate Of Change Alarm.
