FloBoss 407 Instruction Manual
Rev 5/00 G-3
FST — Function Sequence Table, a type of program that can be written by the user in a high-level
language designed by Fisher Controls.
G
GFA — Ground Fault Analysis.
GND — Electrical ground, such as used by the ROC power supply.
GP — Gauge Pressure.
GV101 — Configuration software used to configure ROC units to gather data, as well as most other
functions. Now replaced by ROCLINK software.
H
HART — Highway Addressable Remote Transducer.
hw — Differential pressure.
I, J
ID — Identification.
IEC — Industrial Electrical Code.
IMV — Integral Multiplier Value.
I/O — Input/Output.
I/O Module — Module that plugs into an I/O slot on a ROC or FloBoss 407 to provide an I/O
channel. See Section 3.2 of this manual for a listing of available types of I/O modules.
IRQ — Interrupt Request. Hardware address oriented.
IV — Integral Value.
K
Kbytes — Kilobytes.
kHz — Kilohertz.
L
LCD — Liquid Crystal Display. Display only device used for reading data.
LDP — Local Display Panel. A display-only device that plugs into a ROC300-series unit via a
parallel interface cable. The LDP consists of a 4-line by 20-character alphanumeric display and
four pushbuttons used to access information stored by the ROC.
LED — Light-emitting diode.
LOI — Local Operator Interface. Refers to the serial (RS-232) port on the ROC or FloBoss
through which local communications are established, typically for configuration software
running on a PC.
LPM — Lighting Protection Module. Use this module to provide lightning and power surge
protection for ROCs and FloBoss units.
LRC — Longitudinal Redundancy Checking error checking.
M
mA — Milliamp(s); one thousandth of an ampere.
MCU — Master Controller Unit.
Modbus — A popular device communications protocol developed by Gould-Modicon.
Modular I/O — I/O channels provided on a ROC using I/O modules. See I/O Module.
