S600+ Instruction Manual
Holding
Register
Analog Output number value to be read.
Hz
Hertz.
I, J, K
Integer
Any positive or negative whole number, including zero.
Intelligent I/O
The Intelligent Input Output module (P144), also known as “IIO”.
I/O
Input and Output.
IP
Institute of Petroleum or Ingress protection standard, referring to British standard 5420
or International Electro-Technical Commission standard 144.
IP2
In the calculations section of the generator, this option includes the Liquid Volume
Correction Tables (53 or 54) for a non-US configuration.
IPL 600
Interactive program loader; a tool used to transfer application programs from a PC to
the S600.
IS
Intrinsic Safe. A technique used to prevent excess electrical energy, or faults, in
instrumentation from causing explosions in hazardous atmospheres. Often found in the
process industry. It is the only protection method accepted for use in Zone 0
hazardous areas.
ISO
International Organisation for Standards. A voluntary, non-treaty organization founded
in 1946 which is responsible for creating international standards in many areas,
including computers and communications. Its members are the national standards
organizations of the 89 member countries, including ANSI for the U.S. See
http://www.iso.org.
ISO 5167
Measurement of fluid flow by means of pressure differential devices (such as orifice
plates, nozzles, or Venturi tubes) inserted in circular cross-section conduits.
ISO 6976
Natural gas calculation of calorific values, density, relative density and Wobbe index
from composition.
LED
Light-Emitting Diode (an indicator). On the S600, a light to show the status of the S600
in a visual form. As examples, the Alarm LED shows the status of the machine by the
color of the LED and communications between the main processor board and the IO
boards is shown on the rear of the flow computer by use of the transmit and receive
LEDs.
Mantissa
Numerically significant part of a floating-point number.
Meter
Correction
An option applicable only to liquid turbine applications and used to correct the flow rate
due to temperature and pressure effects on the body of the meter.
Meter
Linearisation
An option used to correct the K Factor or Meter Factor of a pulse input according to the
input frequency. This is used to correct discrepancies caused by the non-linearity of
the transducer connected to the pulse input.
Modbus
A device communications protocol developed by Gould-Modicon and used on the
station supervisory computer data link.
Modem
Modulator Demodulator; a device used to communicate with other equipment using a
telephone network.
Modulate
Superimposing one signal upon another.
MOV
Motor Operated Valve; a valve that is motorized and requires a signal to drive the
valve open, a signal to drive the valve closed, and has a two signals returning to the
S600 to describe the valve as being open, closed, moving, or illegal.
Multiplexor
Multiple Input Selector.
Noise
Random electrical interference.
