C
CAN
The CAN (controller area network) protocol (ISO 11898) for serial bus networks is
designed for the interconnection of smart devices (from multiple manufacturers) in
smart systems for real-time industrial applications. CAN multi-master systems
ensure high data integrity through the implementation of broadcast messaging and
advanced diagnostic mechanisms. Originally developed for use in automobiles,
CAN is now used in a variety of industrial automation control environments.
CANopen protocol
An open industry standard protocol used on the internal communication bus. The
protocol allows the connection of any enhanced CANopen device to the Island bus.
CI
This abbreviation stands for command interface.
CiA
CiA (CAN in Automation) is a non-profit group of manufacturers and users dedicated
to developing and supporting CAN-based higher layer protocols.
CIP
Common Industrial Protocol. Networks that include CIP in the application layer can
communicate seamlessly with other CIP-based networks. For example, the
implementation of CIP in the application layer of an Ethernet TCP/IP network
creates an EtherNet/IP environment. Similarly, CIP in the application layer of a CAN
network creates a DeviceNet environment. Devices on an EtherNet/IP network can
therefore communicate with devices on a DeviceNet network via CIP bridges or
routers.
COB
A COB (communication object) is a unit of transportation (a message) in a CAN-
based network. Communication objects indicate a particular functionality in a
device. They are specified in the CANopen communication profile.
configuration
The arrangement and interconnection of hardware components within a system and
the hardware and software selections that determine the operating characteristics of
the system.
