DTM-based tools and Experion
HART and FOUNDATION Fieldbus models support Device Type Managers (DTMs)
running on Field Device Technology
®
(FDT) hosts such as PACTware or Field Device
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,
