FDT - DMT purpose

integrate field devices (sensors and actors) of different manufacturers in any control orengineering system

device description file (HART, GSD) -> device type manager (DTM)

DTM is a software module (a kind of driver) that comes with each device.DTM encapsulates the device's configuration, functions, parameters and describes theuser interface

The Device Type Manager ...

... knows all business rules of the device

... contains all user dialogs

... does the device configuration anddiagnosis

... generates the device specificdocumentation

... has no data storage capability

... has no direct device link to any device

The Device Type Manager ...

... supports one or several devices

... could be created from existingdevice tools

... could be automatically compiledfrom Device Descriptions

... could be developed from scratch

... should be an Active X Control for use inWebBrowser

... should be designed according to Microsoft MultiLayer Architecture
