Why should you use PD CLC IEC/TR 62453-52-90 - FDT language infrastructure?
PD CLC IEC/TR 62453-52-90 as a part of the IEC 62453 series is an interface specification for developers of FDT components for function control and data access within a client/server architecture. PD CLC IEC/TR 62453-52-90 is a result of an analysis and design process to develop standard interfaces to facilitate the development of servers and clients by multiple vendors that need to interoperate seamlessly. With the integration of fieldbuses into control systems, there are a few other tasks that need to be performed. In addition to Fieldbus- and device-specific tools, there is a need to integrate these tools into higher-level system-wide planning or engineering tools. In particular, for use in extensive and heterogeneous control systems, typically in the area of the process industry, the unambiguous 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 kinds of fieldbuses and thus meets the requirements for integrating different kinds of devices into heterogeneous control systems. Using these guidelines, you enable your end customers to improve their work efficiency.
