Glossary
ControlNet network An open control network that uses the producer/consumer model to combine
the functionality of an I/O network and peer-to-peer network, while providing
high-speed performance for both functions.
cycle Scanning of inputs, execution of algorithms and transmission of output values to
devices.
device description (DD) Abbreviated as DD, this is a set of files (CFF, SYM, and FFO) that describes the
parameter capabilities of a fieldbus device. The file information on these block
parameters includes names, data types, and specifications.
device The term in this manual refers to the instruments that make up the
fieldbus system.
device ID An identifier for a device that the manufacturer assigns. Device IDs must be
unique to the device; no two devices can have the same device ID.
device tag A character string name that uniquely identifies a device on a fieldbus network.
DO Abbreviation for discrete output; signal is generated by the host system and
transmitted to a field device.
Ethernet Physical and data link layer defined by IEEE 802 standards used by EtherNet/IP.
EtherNet/IP An open, industrial networking standard that supports both real-time I/O
messaging and message exchange.
fieldbus A digital, two-way, multi-drop communication link among intelligent
measurement and control devices. It serves as a Local Area Network (LAN) for
advanced process control, remote input/output, and high-speed factory
automation applications.
FOUNDATION Fieldbus The communication network that the Fieldbus Foundation created.
function block A named block consisting of one or more input, output, and contained
parameters. The block performs some control function as its algorithm. Function
blocks are the core components with which you control a system. The Fieldbus
Foundation defines standard sets of function blocks.
gateway Translates another protocol to FOUNDATION fieldbus or vice versa, for
example HART to FOUNDATION fieldbus or Modbus to
FOUNDATION fieldbus.
H1 A FOUNDATION fieldbus segment that operates at 31.25 Kbps.
