FDT/DTM (Field Device Tool / Device Type Manager) technology is an open, vendor-independent standard for integrating field devices into automation and control systems.
FDT defines a common framework that allows different devices and systems to communicate, while DTMs are software components provided by device manufacturers that contain all the device-specific data, functions, and user interfaces.
Together, they enable seamless configuration, diagnostics, and maintenance of field instruments—regardless of manufacturer—through a single, unified interface, improving interoperability, efficiency, and lifecycle management in industrial automation.
