Specifications

G-iv
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 devices. This field is stored in the
HART device and can be modified.
Instantiation
Some FOUNDATION fieldbus devices support instantiation of function or
transducer blocks in the device. This means the device allows a command to
be sent to it that will create or instantiate additional function or transducer
blocks in the device. After being instantiated, these blocks operate like any
other block in the device. The 375 Field Communicator supports the
commands to instantiate and to delete function and transducer blocks in a
fieldbus device.
Internal Flash
Non-volatile memory that stores the operating system, application software,
internal device configurations, event captures, fieldbus statistics, and user
generated text files.
Intrinsic Safety (IS)
Circuits that are designed to limit the amount of energy consumed or
provided to field devices to levels below those that are required to ignite
specific types of hazardous materials under fault and no fault conditions.
Also a method of providing safe operation of electronic process-control
devices in hazardous areas, such as flammable environments. IS systems
keep the available electrical energy in the system low enough that ignition of
the hazardous atmosphere cannot occur.
