Glossary 2
Data Link Layer
(DDL)
Controls transmission of messages onto the fieldbus, and manages access to the
fieldbus through the Link Active Scheduler (LAS). The DLL used by FOUNDATION
fieldbus is defined in IEC 61158 and ISA 50. It includes Publisher/Subscriber,
Client/Server and Source/Sink services.
Device Description
(DD)
Set of files (CFF, SYM and FFO) that describes the parameter capabilities of a fieldbus
device.
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 name you assign to a fieldbus device.
Ethernet Physical and data link layer used by HSE fieldbus.
FF FOUNDATION Fieldbus.
Factory
Acceptance Test
(FAT)
The final test at the vendor’s facility of the integrated system being purchased.
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.
Fieldbus Access
Sublayer (FAS)
The Fieldbus Access Sublayer (FAS) maps the Fieldbus Message Specification (FMS)
onto the Data Link Layer (DLL).
Fieldbus
Foundation
The organization that developed a fieldbus network specifically based upon the work
and principles of the ISA/IEC standards committees.
FOUNDATION
Fieldbus
The communications network that the Fieldbus Foundation created.
FFLD Foundation Fieldbus Linking Device; an HSE node that connects either two or four H1
segments to an HSE network and to the Ethernet/IP network. The 1757-FFLD supports
all H1 and HSE functionality and basic, link master, and bridge modes of operation (as
specified in the FOUNDATION fieldbus Technical Overview) as well as Class 1 CIP
produce/consume and Class 3 CIP server.
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. There are ten function blocks for the most basic
control and I/O functions.
H1 A two-way, digital, serial communications link that operates at 31.25 Kb.
H1 Field Device A fieldbus device connected directly to an H1 fieldbus. Typical H1 Field Devices are
valves and transmitters.
HSE High Speed Ethernet that operates at 10/100 Mb, full-duplex communications link.
HSE Device Any device connected directly to HSE media that contains a conformant FOUNDATION
Fieldbus HSE communications stack, including a configurable Network Management
Agent (NMA) (e.g., linking devices, I/O gateways, and HSE field devices).
HSE Host Non-HSE devices capable of communicating with HSE devices (e.g., configurators and
operator workstations).
HSE Linking
Device
A device used to interconnect H1 fieldbus networks/segments to High Speed Ethernet
(HSE) to create a larger system.
