F
Firmware — Internal software that is factory-loaded into a form of ROM. In the ROC, FloBoss, or
EF-Series unit, the firmware supplies the software used for gathering input data, converting raw
input data calculated values, storing values, and providing control signals.
FlashPAC — ROM (and RAM) module that contains the operating system, applications firmware, and
communications protocol in a ROC300-Series unit.
Flash ROM — A type of read-only memory that can be electrically re-programmed. It is a form of
permanent memory (needs no backup power).
FloBoss — A microprocessor-based flow computer that provides remote monitoring and control.
Trademarked by Fisher Controls.
FM — Factory Mutual.
FSK — Frequency Shift Keyed.
FST — Function Sequence Table, a type of program that can be written by the user in a high-level
language designed by Fisher Controls. One or more FSTs can be set up in a ROC or FloBoss.
G
GFA — Ground Fault Analysis.
GND — Electrical ground, such as used by the ROC or flow computer power supply.
GP — Gauge Pressure.
H
HART — Highway Addressable Remote Transducer.
hw — Differential pressure.
I, J
ID — Identification.
IEC — Industrial Electrical Code.
IMS — Internet Measurement Services.
IMV — Integral Multiplier Value.
I/O — Input/Output.
IRQ — Interrupt Request. Hardware address oriented.
IV — Integral Value.
