KB
Kilobytes.
kHz
KiloHertz.
L
LCD
Liquid Crystal Display.
LED
Light-Emitting Diode. A status light.
Long Tag
A name (up to 32 characters) for a device in the wireless network. Each device in the
wireless network must have a unique long tag, different from all other devices in the
network. Typically you specify the long tag using a Field Communicator or PC-based
AMS Device Manager software.
M
m
Meter.
mA
Milliamp(s); one thousandth of an ampere.
MAC Address
Media Access Control Address; a hardware address that uniquely identifies each node
of a network.
Modbus
A popular device communications protocol developed by Gould-Modicon.
mm
Millimeter.
MMBTU
Million British Thermal Units.
msec
Millisecond, or 0.001 second.
MVS
Multi-Variable Sensor. A device that provides differential pressure, static pressure, and
temperature inputs to a flow computer..
mV
Millivolts, or 0.001 volt.
mW
Milliwatts, or 0.001 watt.
N
NaN
Not-a-Number. This refers to a value which cannot be expressed as a number, such as
a division by zero error condition.
NEC
National Electrical Code.
Network ID
An identifying number for the wireless network. During transmitter setup, you assign
the same Network ID to every device in the network, typically using a Field
Communicator or PC-based AMS Device Manager software. When you configure your
ControlWave project using ControlWave Designer, you will need to know the Network
ID for this network.
NEMA
National Electrical Manufacturer’s Association. See

.
Node
A basic element of a network. Typically this would be an RTU or flow computer.
O
OE
Abbreviation for OpenEnterprise
– a brand name for our SCADA software package.
Off-line
Accomplished while the target device is not connected (by a communications link).
Ohms
Units of electrical resistance.
On-line
Accomplished while connected (by a communications link) to the target device.
Orifice meter
A meter that records the flow rate of gas through a pipeline. The flow rate is calculated
from the pressure differential created by the fluid passing through an orifice of a
particular size and other parameters.
