FDT Technology Overview
What is FDT?
FDT (Field Device Tool) technology
standardizes software
interface between
field devices drivers
and host systems.
FDT Technology Overview
Concept
 DTM (Device Type
Manager) is a
software driver
delivered with the
device
 Standardized software
interface
 Similar idea as a
print driver

The Simplest Case: Standalone
Tools (2)
 Typical Use Cases:
 Workshops or small installations
 Online connection to the device
 Operation mainly via the DTM’s GUI
 User has access to all DTM functionality, e.g. by switching
between different tab cards
 Current configuration and parameters are read from the
device
 Parameters may be written to the device e.g. for test purposes

FDT Technology Overview
The Complex Case: Control
Systems (2)
 Typical Use Cases:
 Different ‘Frame Applications’ may use a DTM in different
contexts
 Availability of DTM functions is controlled according to the
application context
 All settings loaded to the device are stored in a system
database
 Online connection to the device is not always available
DTM works on database only
 DTM functions are frequently used in the background w/o
starting a user dialog

FDT Technical Details
Communication
 Each component wraps the communication frame from the
component below, WITHOUT knowing the contents
 Routing through system topology
 DTM below does not have any knowledge about the network
topology
 DTM must only support its own communication protocol
 Communication / routing through ANY network topology, no
limitations
 Communication / routing is possible even if the underlying
protocol is unknown by the engineering or standalone tool
