FDT container applications can be stand-alone tools, or can be part of other engineering tools such
web browsers providing FDT interfaces. Since FDT standardizes the interfaces, it allows devices
from different manufacturers to be integrated in any automation system, regardless of the fieldbus
system.
CX-IntegratorFDT is an example of a FDT container application. It is described in detail in the follow-
ing sections.
 Device DTM
DTMs are provided by the manufacturer of the device. A DTM is comparable to a printer driver,
which allows interactive configuration and diagnostics.
The DTM provides not only the configuration, manipulation and monitoring functions for a device
including the user interface functions, it also provides the connection technology to the device.
 DTM Properties
In general, a DTM is a Microsoft COM-component, which can be executed from within a FDT con-
tainer application. A DTM is not a stand-alone tool, it requires a FDT container application to be exe-
cuted. The DTM provides a number of interface functions, through which it can be controlled and
accessed in order to transfer data to or from the DTM. A DTM provides all the options for configura-
tion and monitoring of a device, which it can present to the user through its own user interface.
 ActiveX User Interface
The user interface for a DTM is provided using ActiveX windows. Control of these windows is done
by the DTM, but the FDT container application can request specific user input from the DTM, based
on which the DTM will provide the necessary ActiveX windows. In general multi-language user inter-
face windows, including DTM specific Help files are supported by the DTM.
 XML based Data Transfer
Data transfer to and from a DTM is provided using XML-documents. The XML-documents are stan-
dardized for the communication between the FDT container application and for communication
between DTMs. An additional specification covers the definition of XML-data formats for the transfer
of application specific data, such as PROFIBUS data.
 Communication DTM
In general, a device configuration DTM is accompanied by a communication DTM. This specific
DTM facilitates device specific communication, e.g. for downloading a configuration to a PROFIBUS
Master Unit and/or for retrieving monitoring information from PROFIBUS Master Unit. It may incor-
porate the specific communication protocol, or rely on other available drivers.
 CX-ConfiguratorFDT
CX-ConfiguratorFDT is an FDT container application. Together with this container application,
OMRON provides four DTMs:
• A DTM to facilitate configuration and operation of the CJ1W-PRM21 PROFIBUS DP-V1 Mas-
ter Unit (As of Unit version 2.0).
• A DTM to facilitate configuration of the CJ1W-PRM21 PROFIBUS DP Master Unit (Unit ver-
sion 1.0).
• A DTM to facilitate configuration of the SmartSlice GRT1-series GRT1-PRT PROFIBUS Com-
munication Unit.
• A DTM to facilitate integration of GSD file based devices into CX-Integrator FDT (1-1-10 GSD
File Technology for more information)
