Extended Functions

Optional capability that can be enabled for certain point types, increasing

the number of functions the point can perform. Common extended

functions are pressure/temperature compensation, signal

characterization, and extended alarms.

Faceplate An established display figure that shows the most important information

about a process control point. Faceplates are vertical rectangles, several

of which fit on a console screen at once.

FDFWD Acronym: Feedforward

Feedforward (FF or FDFWD)

A type of control action that takes into account signal other than the

process variable, in order to anticipate and minimize deviations of the

process variable.

FF Acronym: Feedforward

FIL Abbreviation: Filter

Filter Time Constant (FTIM)

The length of time required for 63.21 percent of a step change at the

input of a filter to appear at the output.

Firmware Computer or microprocessor programming stored on a chip, in such a

way that users cannot change the programming.

Floating Point Pertaining to decimal value presentation in which the position of the

decimal point does not remain fixed with respect to one end of the digits.

FST Acronym: Function Sequence Table

FTIM Acronym: Filter Time Constant

Function Sequence Table (FST)

A list of controller instructions arranged to perform logical and

mathematical operations in a specific order. An FST resembles a

sequence of programming subroutines, but defining an FST does not

involve actual computer programming.

Gain The change in the output of a controller divided by the change in the

input to the controller. The amount of gain determines how much the

controller output changes in response to process deviations.
