device. A similar connection may be realized using PC configuration software.
Each transmitter includes a configuration database that stores its operating characteristics
in a non-volatile memory.
The handheld or PC software is used to establish and/or change selected operating
parameters in a transmitter database. The process of viewing and/or changing database
parameters is called configuration.
Configuration can be accomplished both online and offline with the transmitter powered
up and connected to the handheld.
Online configuration immediately changes the transmitter operating parameters. For
offline configuration, transmitter operating characteristics are entered into the handheld
memory for subsequent downloading to transmitter.

1.4.3 DTM-based tools and Experion

HART and FOUNDATION Fieldbus models support Device Type Managers (DTMs)
running on Field Device Technology
Manager (FDM) / Experion.
The transmitter establishes communication with the host systems using DD or DTM.
Device Description (DD)
DD is a binary file that provides the definition for parameters in the FBAP of the
transmitter. For example, DD refers to the function blocks that a transmitter contains, and
the corresponding parameters in the blocks that are critical to the interoperability of
Fieldbus devices. They define the data required to establish communications between
different Fieldbus devices from multiple vendors with control system hosts. The DD
provides an extended description of each object in the Virtual Field Device (VFD).
The Fieldbus Foundation provides the DD for all registered devices on its website,
