ARP address resolution protocol. IP’s network layer protocol uses ARP to map an IP
address to a MAC (hardware) address.
auto baud The automatic assignment and detection of a common baud rate as well as the
ability of a device on a network to adapt to that rate.
auto-addressing The assignment of an address to each island bus I/O module and preferred device.
auto-
configuration
The ability of island modules to operate with predefined default parameters. A
configuration of the island bus based completely on the actual assembly of I/O
modules.
BootP bootstrap protocol. A UDP/IP protocol that allows an internet node to obtain its IP
parameters based on its MAC address.
BOS beginning of segment. When more than one segment of I/O modules is used in an
island, an STB XBE 1200 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.
bus arbitrator A master on a Fipio network.
CAN controller area network. The CAN 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 standard CANopen device to the island bus.
