DL8000 Preset Instruction Manual
A-4 Glossary Revised February-2016
Firmware
Internal software that is factory-loaded into a form of ROM. In a ROC, the firmware
supplies the software used for gathering input data, converting raw input data values,
storing values, and providing control signals.
FlashPAC
module
ROM and RAM module for a ROC300-Series unit that contains the operating system,
applications firmware, and communications protocol.
Flash ROM
A type of read-only memory that can be electrically re-programmed. It is a form of
permanent memory (requires no backup power). Also called Flash memory.
FloBoss
A microprocess-based device that provides flow calculations, remote monitoring, and
remote control. A FloBoss is a type of ROC.
FM
Factory Mutual.
Force
Write an ON/OFF, True/False, or 1/0 value to a coil.
FPV
Compressibility Factor.
FSK
Frequency Shift Keypad.
FST
Function Sequence Table, a type of user-written program in a high-level language
designed by Emerson Process Management’s Remote Automation Solutions Division.
Ft
Foot or feet.
G
GFA
Ground Fault Analysis.
GND
Electrical ground, such as used by the ROC unit’s power supply.
GP
Gauge Pressure.
Gross Quantity
The indicated quantity times the meter factor derived from a meter proving of the flow
meter at a specific flow rate. Calculation: gross quantity = indicated quantity times
meter factor.
H
HART
®
Highway Addressable Remote Transducer.
Holding
Register
Analog output number value to be read.
Hw
Differential pressure.
Hz
Hertz.
I, J
IC
Integrated Circuit. Also, Industry Canada (more recently known as Measurement
Canada), an organization that grants custody transfer approvals on certain ROC units.
ID
Identification.
IEC
Industrial Electrical Code or International Electrotechnical Commission. See
http://www.iec.ch.
IEEE
Institute of Electrical and Electronic Engineers. A professional organization that, in
conjunction with the International Standards Organization (ISO), establishes and
maintains the Open System Interconnection (OSI) reference model and an international
standard for the organization of local area networks (LANs). Refer to
http://www.ieee.org.
IMV
Integral Multiplier Value, used in AGA3 (orifice) calculations.
Indicated
Quantity
The change in the flow meter reading that occurs during a product flow measurement
operation. (Not displayed by the DL8000 calculation: indicated quantity = end reading
minus start reading.)
Input
Digital input, a bit to be read.
