BOS BOS stands for beginning of segment. When more than 1 segment of I/O modules

is used in an Island, an STB XBE 1200 or an STB XBE 1300 BOS module is

installed in the first position in each extension segment. Its job is to carry Island bus

communications to and generate logic power for the modules in the extension

segment. Which BOS module must be selected depends on the module types that

shall follow.

bus arbitrator A master on a Fipio network.

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 error 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.
