119 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. FOUNDATION 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.
