2.2 Where FDT Fits

Although FDT is primarily designed to control the functionality of a device and for accessing data to configure parts of the control system, FDT interfaces can be used in many places within an application. At the lowest level they can get raw data from the devices into a SCADA or DCS to configure the bus master. At a higher level the Frame Application can start a device specific diagnosis application via the DTM. The architecture and design makes it possible to build and to integrate scalable DTMs, where the functionality depends on the capabilities of the device.
