Field Device Tool (FDT)
The PLC controlling the HART terminal can therefore linked to the "Beckhoff ComDTM" either via a search or
by entering the known IP address or host name, which subsequently enables access to the sensor-/actuator-
specific device driver (DTM). After successful connection, all EtherCAT master systems that exist on the
target system (including a local computer, for example) are automatically scanned for HART devices. Any
channels that are found are then displayed accordingly:
One possible form of this application shows:
• On the left a Project Explorer with the currently configured devices
• In the center the menus for the individual objects / DTMs
• On the right the device catalog showing the DTMs available for selection
Fig. 129: Example FDT application
The device DTMs can be added in the Project Explorer under the channels (for the assignment
channel → DTM). To this end an additional scan function id available, in order to limit the selection of
suitable device drivers for the already connected sensors / actuators to the device-specific variants (see
also: Accessing a sensor/ actuator by scanning the DTM [} 125]).
The following diagram shows a summary of the whole procedure:
