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 mech-
anisms 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 As-
pect Objects.
A product that is Industrial IT enabled has been verified according to the process of Indus-
trial 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 participat-
ing 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
Longitudinal Redundancy Check
In computer networking, a Media Access Control address (MAC address) is a unique identi-
fier assigned to most network adapters or network interface cards (NICs) by the manufac-
turer for identification, and used in the Media Access Control protocol sub-layer. If assigned
by the manufacturer, a MAC address usually encodes the manufacturer's registered identifi-
cation number.
A measurement is a value computed by the controller through its analog and digital inputs.
Measurements can be read from the RVT front plate, or through the Modbus protocol.
It is an optional small interface module through which the RVT is connected to an external
Modbus serial communication bus. It performs an optical to RS485 conversion. The commu-
nication with the Modbus adapter is activated with an RVT parameter.
OLE™ for Process Control. OPC is Plug-n-Play in the field of Automation and HMI. OLE™
for Process Control (OPC™) is the most standard way for connecting hardware and data
devices with HMI client applications.
OPC is a concept agreed upon by a committee of members from the OPC foundation. Most
automation companies in the market place including ABB are members of this foundation.
OPC uses state-of-the art technologies like COM, DCOM, ActiveX of Microsoft and makes
development and programming easier.
In the OPC world, there are two major types of applications: OPC Servers and OPC Clients.
OPC Server applications are used to collect data from the data sources like hardware de-
vices. At the bottom level, the servers are mainly for reading inputs and writing outputs of the
data sources. At the upper level, the servers make the data available in a standard way to
the OPC client applications.
The OPC Client applications can communicate directly with the OPC servers and get the
data. This way OPC enhances the interface between client and server applications by
providing a standard mechanism to communicate data from a data source to any client appli-
cation.
A parameter is an operating data for the controller. Parameters can be read and pro-
grammed with the RVT front plate, or through the Modbus protocol.
