FDT/DTM Technology
The FDT/DTM concept specifies the interface between the engineering systems called Field Device Tools
(FDT), and the device-specific software components called Device Type Managers (DTM). FDT/DTM is the
most recent advancement in Configurators.
The FDT/DTM concept separates the device-dependent functionality (which is in the DTM) from the application.
It provides separate interfaces for device configuration, monitoring and maintenance solutions, which before
largely depended on the manufacturer of the application. Because of this concept, any type of network can be
configured and accessed, provided the appropriate DTMs are available.
An FDT container application facilitates configuration of network devices and parameterizing and/or
manipulating their operational modes. All device-dependent functionality is concentrated in the DTM.
FDT container applications can be stand-alone tools or can be part of other engineering tools such as 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-ConfiguratorFDT is an example of an FDT container application.
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.
A DTM provides all the options for configuration and monitoring of a device, which it can present to the user
through its own user interface. The user interface for a DTM is provided using ActiveX windows. In general
multi-language user interface windows, including DTM-specific Help files are supported by the 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 PROFINET IO Controller Unit and/or
for retrieving monitoring information from a PROFINET IO Controller Unit. It may incorporate the specific
communication protocol or rely on other available drivers.
