A binary digit, representing a one or zero
An electrical circuit over which data is transmitted
A whole number value represented by eight bits (0 to 255)
A connection to an electrically conductive housing or frame of a device. It may or may not be
connected to Earth Ground.
The telegram structure for Modbus transmission is implemented in registers (WORD) or coils
(BOOL). A coil may be either 8 or 16 bits in length.
The voltage reference point of a circuit. It may or may not be connected to earth ground,
though it is generally assumed to be at zero volts, unless otherwise indicated. In floating cir-
cuits, the common is sometimes at a relatively high potential. This term is sometimes used
interchangeably with the term "Ground" or GND
Cyclic Redundancy Check. Complex error checking on a message block.
ClearToSend hardware handshaking signal. Used with RequestToSend.
Global zero voltage reference point. Physical connection is made to the earth through a
grounding rod, water pipe or other reliable connection.
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
A number system using a decimal 16 as its base. A single digit 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 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.
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
