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. |
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 | |
| parameters. A basic I/O module cannot be reconfigured with the Advantys |
| configuration software and cannot be used in reflex actions. |
basic network | A |
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 |
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. |
