to the earth through a grounding rod, water pipe or other reliable
connection.
is a family of frame-based computer networking technologies for
local area networks (LANs). It defines a number of wiring and
signalling standards for the Physical layer of the OSI networking
model as well as a common addressing format and Media Access
Control at Data Link Layer.
It may or may not be connected to earth ground, though it is
generally assumed to be at zero volts. Sometimes used
interchangeably with the term "Common".
method of data flow control for serial communications
number in HEX ranges from 0 to 15, represented by 0 to 9 and A to
F.
Human-Machine Interface (formerly MMI)
Umbrella concept for ABB's vision for enterprise automation.
The architecture of the Industrial IT system. The architecture
defines how the system is built, in terms of basic concepts,
underlying technologies, system topology, modularity, and
mechanisms for interaction between different parts of the
system. It also defines concepts, rules, and guidelines that a
component must comply with in order to fit in the Industrial IT
system. A central feature of the IIT architecture is that information
and functions are centred on Aspect Objects.
A product that is Industrial IT enabled has been verified according
to the process of Industrial IT certification. It has the right to use
the "Industrial IT enabled" symbol.
An Internet Protocol (IP) address is a numerical label that is
assigned to devices participating in a computer network that uses
the Internet Protocol for communication between its nodes. An IP
address serves two principal functions: host or network interface
identification and location addressing.
A test used for checking functionality of a serial port, utilizing a
test plug that connects send, receive and handshaking signals
Analog value consisting of two consecutive 16-bit registers
