This part of I EC 62453 is an interface specification for developers of Field Device Tool (FDT) com ponents for function control and data access within a client/server architecture The specification is a result of an anal ysis and design process to develop standard interfaces to facilitate the development of servers and clients by m ultiple vendors that need to interoperate seam lessl y With the integration of fieldbuses into control system s, there are a few other tasks which need to be performed I n addition to fieldbus- and device-specific tools, there is a need to integrate these tools into higher-level system -wide planning or engineering tools I n particular, for use in extensive and heterogeneous control system s, typicall y in the area of the process industry, the unam biguous definition of engineering interfaces that are easy to use for all those involved is of great importance A device-specific software component, called Device Type Manager (DTM), is supplied by the field device manufacturer with its device The DTM is integrated into engineering tools via the FDT interfaces defined in this specification The approach to integration is in general open for all kind of fieldbusses and thus meets the requirem ents for integrating different kinds of devices into heterogeneous control system s Figure shows how this part of the I EC TR 62453-52-xy series is aligned in
