Glossary

ARP	address resolution protocol. The IP network layer protocol, which 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-	The ability of island modules to operate with predefined default parameters. A
configuration	configuration of the island bus based completely on the actual assembly of I/O
	modules.

B

basic I/O	Low-cost Advantys STB input/output modules that use a fixed set of operating
	parameters. A basic I/O module cannot be reconfigured with the Advantys
	configuration software and cannot be used in reflex actions.
basic network	A low-cost Advantys STB network interface module that supports a single segment
interface	of up to 12 Advantys STB I/O modules. A basic NIM does not support the Advantys
	configuration software, reflex actions, island bus extensions, nor the use of an HMI
	panel.
basic power	A low-cost Advantys STB PDM that distributes sensor power and actuator power
distribution	over a single field power bus on the island. The bus provides a maximum of 4 A total
module	power. A basic PDM requires one 5 A fuse to protect the I/O.
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.
