Fieldbus device
A device that communicates information using the fieldbus protocol on
a digital, serial, multidrop data bus.
Fieldbus Foundation
The organization that develops and supports FOUNDATION fieldbus, an
international, interoperable standard for communication of process
automation and control information. Members include suppliers and
end users of process control and manufacturing automation products.
Support for the standard includes education, interoperability and
conformance testing, testing tools, and development software.
FOUNDATION fieldbus
A specific fieldbus technology developed and supported by Emerson
Process Management and the other members of the independent
Fieldbus Foundation. F
OUNDATION fieldbus technology uses device
descriptions and function blocks to enable intelligent devices to
execute control functions traditionally performed by a distributed
control system.
Graphics
A feature that enables the 475 Field Communicator to display device
information as images, charts, and graphs by using enhanced
Electronic Device Description Language, EDDL. To view the graphical
representations, you need a device using an enhanced EDDL device
description.
HART device
A device that communicates information using the HART protocol.
HART loop
A communication network in which the master and slave device are
HART-smart or HART-compatible.
HART protocol
Highway Addressable Remote Transducer communication protocol.
An industry-standard protocol for digitally enhanced 4-20 mA
communication with Smart devices.
HART tag
An 8-character field used to identify a device. A 32-character long tag
is also possible with HART Universal Revision 6 or higher devices.
This field is stored in the HART device and can be modified.
