G-iii
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 field 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 device. This field is
stored in the HART device and can be modified.
Instantiation
Some F fieldbus devices support instantiation of function
OUNDATION
blocks in the device. This means the device allows a command to be
sent to it that will create or instantiate additional function blocks in the
device. Once instantiated, these function blocks operate like any
other block in the device. The 375 Field Communicator does not
currently support the command to instantiate function blocks in a
fieldbus device. The 375 Field Communicator is, however, able to
access function blocks that have been instantiated by other external
means.
Internal Flash
Non-volatile memory that stores the OS application software, internal
device configurations, event captures, fieldbus statistics, and user
generated text files.
