the operator application.
Software
Description
FDT
(Field Device Tool)
The FDT specification defines the interaction
of DTMs with host computers or software. An
FDT frame application is a PC-based soft-
ware including many DTMs for configuration
monitoring and programming of field devices.
Both the Diagnostic Manager DTM and the
Gateway DTM run in an FDT environment.
