FDT - Field Device Tool
FDT is a standard for interface standardization between device and user interface. With the help of FDT, device
operation can be integrated easily and quickly.
FDT/DTM -Technology
The FDT-technology (Field Device Tool) describes the communication of intelligent field devices. This technology
allows the standard compilation of complex communication architecture of modern, procedural installations in a
superior system. Each communication component between field device and superior system is represented by a
DTM (Device Type Manager). The interface between system and bus is realized by a COM-DTM. The network
topologies of the existing installations often consist of different bus systems that are connected with the help of
protocol converters. Gateway-DTMs make it possible to change the communication type within the FDT. The filed
devices are represented by device-DTMs. The DTMs are managed in a FDT-frame. All component-specific
functions like parameterization, configuration, display, measurement and diagnostics are tasks of the respective
DTMs and not of the frame application. Next to the management and display of the DTMs, the FDT-frame supports
security levels, up- and download functions, establishment and storage of installation architecture. FDT-frames
are available as stand-alone solutionsPACTwareTM) but also integrated into control systems and asset
management systems.
With the help of the FDT-technology you will be able to parameterize your field devices via an application, and to
graphically display measured values and diagnostics from your PC.
The FDT-technology offers the following user advantages:
 Standard navigation and user guidance
 DTMs are supported by almost all systems
 Certified DTMs guarantee interoperability
 Keep occupied with content and not with display
 Suitable for all field devices
 Suitable for all field devices
FF - FOUNDATIONTM fieldbus
is used worldwide and permits that the control is assigned to the field, has time-stamps for alarms in the field
devices, comprehensive interoperability functions and a unique user layer for expanded functions. The
FOUNDATIONTM fieldbus is a fieldbus standard primarily geared toward the requirements of process automation
and represents the functionally comprehensive fieldbus solution for this type of application.
Flexible Function Blocks
Flexible function blocks are suitable function blocks per a specific task wich may be freely defined and
programmed. Input, output and included parameters depend on the programmed algorithm of the FFB.
Programming is done with an IEC-6-1131 programming language.
