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 interface
A low-cost Advantys STB network interface module that supports up to 12 Advantys
STB I/O modules. A basic NIM does not support the Advantys Configuration
Software, reflex actions, nor the use of an HMI panel.
basic power distribution module
A low-cost Advantys STB PDM that distributes sensor power and actuator power
over a single field power bus on the Island. The bus provides a maximum of 4 A total
power. A basic PDM requires a 5 A fuse to protect the I/O.
BootP
BootP (bootstrap protocol) is an UDP/IP protocol that allows an internet node to
obtain its IP parameters based on its MAC address.
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.
