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 in an integrated circuit,
in such a way that users cannot change the programming.
First In, First Out (FIFO)
An order for handling or processing items placed in a queue or buffer.

Fixed Gain (K) A multiplication factor for a process control value. System or device
configuration establishes the amount of this factor. A user cannot change
a fixed gain without reconfiguring.
FST Acronym: Function Sequence Table
FTIM Acronym: Filter Time Constant
Full Duplex Communication
Simultaneous transmission in both directions over a communications
channel.
FWD Abbreviation: Forward
G
Gain The ratio of output change to input change in a controller. The amount of
gain determines how much the controller output initially changes in
response to process deviations.
H
Hard Manual Mode (HMAN)
A special control mode associated with controller backup: in some Fisher
systems, if a controller fails, additional hardware lets the operator retain
manual mode control of the loop output.
Hexadecimal A base 16 number system commonly used in digital computers. It
consists of the numbers 0 through 9 followed by the letters A through F,
