FDT Use Cases
(beyond device
configuration)
Motivation for this presentation
FDT is more than…
... a Frame Application that …
… has a Tree View
on left hand side that
shows hierachical
ordered network
topology
… opens DTM user
interfaces for offline or
online parameterization
… uploads and
downloads
device parameters

interface to directly connect to devices and read
process variables.

TransactionRequest()
Process variable address information
from Process Channel Parameter
Process variable value read from the
device. Returned byte stream must be
converted to data type described in

Process Value Reading via OPC Server (1/2)
If OPC Server acts as a FDT Frame Application it
even can use the Communication or Gateway
DTMs, so it becomes independent from used
hardware.
