FDT/DTM FRAMEWORK FOR NEW FIELD DEVICE TOOLS

摘要

We have developed FieldMate, a field device configuration software package offering a graphical interface and easy operation, by adopting FDT/DTM (Field Device Tool/Device Type Manager), a new open framework for field device tools. FDT defines the data exchange interface between field devices and each of the control systems, engineering tools and asset management system tools. A DTM is a software component that works on the framework and facilitates operation through a graphical interface. Many field device vendors including Yokogawa develop and provide DTMs which work on any control systems that have the same framework. FDT/DTM is becoming popular in not only the process automation industry but also the factory automation industry. This paper describes the characteristics of FDT/ DTM and gives a technical overview.
